yup - that's where I'm putting Synergy eventually
And that photoshoped chick interesting... kinda weird, but provacative.
robin_sz: The average BDusr wouldn't be likely to use a deb repo
5 gigs DAILY traffic... what the hell??
websys, are they fast?
what's the server apps they got running?
paul_c: conversley, theres certainly a few that would prefer a simple apt-get install a 630 meg download
mysql, apache, php versions?
not sure but my customers told me about it
robin_sz: So we set up both.
paul_c: great plan!
* robin_sz kisses paul_c
already have some of the debs on a server.
* paul_c runs to find the disinfectant
paul_c: gezr mentioned some debian script that exports and builda a directory structure suitable for adding a ine to apt/sources
paul_c: from what I remember, it makes all the index files and such
got the rule set already.
There's the apt-utils package, or apt-move
I used to dislike debain, but .. its completely swung me now
websys, php5, and mysql 4.1 :) sweet.
they're good for that price.
robin_sz's a swinger, and he kisses guy <- Too Much Information
you should join #london.pm
Depends where he's kissing him
I still remember the tech meet when two girls demonstrated the new killer app for 3G phones ...
it involved tongues ... ;)
* paul_c has met more oddballs here....
Pam keeps making eyes at me....
paul_c: It takes one to know one :D
paul_c, I don't know who's balls you're meeting... but I'll just stay over here now.
easiest way to break blue locktight is?
or maybe it's read.
lots of it?
as much as it will stand
or just a propane torch?
doesnt need to glow
250 degrees or so
oh. good. I was hoping it didn't need to glow
don't breath the fumes
so, an outdoor thing... great.
Need to bore a tap a whole for a 1-9/16" x 18tpi into a steel plate... or should I do in aluminium?
I'll do steel... much cheaper.
18tpi is fairly fine at that size
ooh, yes please!
* paul_c introduces robin_sz to Pam.
actually, 18tpi in ally, hmm I think Id just make the hole undersize andget a wrench
I have the tap. :)
robin_sz: You'll like Pam.
ballscrew nuts... standard size for that sized ballnut. They do it to sell you the expensive flanges.
mmm .. flanges.
robin_sz: She is now.
paul_c: hmmm. I'll pass, unless by chance shes turned out looking like pamela anderson
more like a number 13
paul_c: I thought you prefered old trouts
* paul_c prefers young, educated ladies
Then don't come to Ohio - we have a shortage
ah. ok, I'll pass.
gotta go - Having dinner with Clyde
I wish I had the stock here at home already. Time to forage for metal on that shelf full of stock.
anyone ever used a boring head? What's the proper usage of one?
I've got a 3/8" plate that I need to bore a 1.5" dia hole...
Proper usage for a boring head: carefully.
well? it's like what?
drill out to whatever I can... boring, incrementing slowly?
Regular head on a vertical mill?
run the boring head the slowest possible.
yeah, regular hear, vertical mill.
Ok. Yes, make as big a starter hole as you can
I've got a dril that's 1"... so i'm gonna step drill it to that size... and then use the boring head... [which is the part I'm kinda stuck at]
And if you have a table Z, use it instead of the quill
didn't come with instructions.
no table Z... [knee]. I have a column [which doesn't index], and quill only.
[03:11:06] <A-L-P-H-A> http://www.bellmachineryltd.com/new_kingpdm25.htm
except in an ugly green.
asdfqwega, k, so this is what I'm gonna do, step drill, change to the boring head... mill it out with the slowest RPM... incrementing the head as after each pass threw the stock.
Use the quill feed wheel
Basically, you want to feed it slowly, and using the hand lever has too much of a possibility of it grabbing
If the chatter gets too bad, one thing I've done was loosen the quill to "sticky but not stiff", and use the quill feed and hand feed in opposing
I push up lightly with the hand feed, and let the quill feed push it down
This takes up whatever backlash there might be in the quill feed
thanks for the tips.

oh my the blast booth is comming along
got me a black and decker drill and jig saw, the cheap stuff, and its working nicely, not rechargable, got them cords I cAN cut on :)
A-L-P-H-A : you get your hole bored?
asdfqwega : how you doing tonight?
I'm not doing to bad - doing up my books for taxes
I think im really tired
Im not sure, I have 2 more boards to put onthe pyramid base, then some cuts and then some other stuff yet to do, then im going to work on assembly
Where you located, gezr?
Just curious - there's places you can get a blasting cabinet easier than building one
I'm trying to remember a name of a place that even sells kits for blasting cabinets
im in central arkansas
I can buy one any day
this is somewhat an excuse to get some tools and have some fun :)
Oh, well, have at it then
less I spend on stuff I wont use everyday, more I can spend on stuff I will use more often
Ugh...time for a coffee run
asdfqwega : did you see the photos I put up of the cabinet before the recent mods I havent finished yet?
No, I haven't
www.masternode.net/gallery cant remember which dir they are in
I'll take a gander when I get back
Careful with the power tools
gezr, yes. :)
power is still on
* anonimasu yawns
morning folks. :)
looking at proximity switches for home switches.
today, I am having fun with snmp
proxi switches are EXPENSIVE. :(
wonder if I can get a half dozen for samples. :) hehe
and useless in your application too :)
you are using steppers, right?
so .. your homing accuracy depends on switch accuracy, unliek a servo
someone mentioned it... so I was curious.
so the proximity sensor can be used as a switch.
proximity switches are not very repeatable
supposedly this guy can get it within +/- 1 step.
let me put it anothe way
microswitches are $3
I have like a dozen of them.
wellm that was it really :)
oh. just the price diff. understood.
my experience with proximity switches is they are very variable in when they go off
hmm... how about hall sensors?
aren't they really accurate? but the problem is that my machine is made of iron.
I would hae thought the same thing applied
halls were a bit temperature dependent I thought
My mill is inside the basement.
same with my lathe
even my 250K laser uses microswitches ...
hmm. okie. :)
what's the repeatablity of the microswitches?
good. very good.
depepns a bit on how you mount them
I use them with a roller and a ramp
so if it overshoots, death doesnt occur
how should it be mounted? got a picture by chance?
don think i have
heres how it is on most pro gear.
some sort of slotted track
damn my internet is so slow
with a plastic or ally wedge ... sorts_____/------
like a 45degree section an a 5mm step
the microswitch has a roller
you can move the wedge in the track to adjust the zero
ooh, one thing that might work if you dont want you switches
slotted IR sensors
I was thinking those... from a mouse.
yeah, or an old printer
seen those used, but dust may be an issue
* robin_sz luuurrvs mrtg
traffic grapher, sucks data out over smnp and graphs it
[14:13:56] <robin_sz> http://adsl.redpoint.org.uk:82/mrtg/
the 3com switch in my network, plus a bit of ssytem data from another host
you can click the graphs for more detail
well, i find it kinda cute anyway
it's useful... kinda. :)
I can't get omron.ca to work properly.
ahh. enclose an photomicrosensor in a box, with a piston and spring as a trigger mechanism. Making it liquid + dust proof.
it goes ... kilo, deca, <base>, centi, mili, micro, pico, nano right?
micro, nano, pico
uF, nF, pF
found a device that is oh... 5um accuracy... but I realized... if I just modify some code, I could get that accuracy as well... so that I start the table movement, I trigger a switch, slow down, stop when trigger the optical sensor.
I got my machine to work
although it dosent seem like you can redefine pins in the config yet
how can i increase the number of step pulse/second limit in EMC?
so I guess I'll have to re-wire everything
my step motor moves slowly (100 rev/m). i have a driver card with 5000 microstep. i want to increase rev/m. when i increase maximum_velacity higher than 6 (mm/sec) i get an error message: Error - axis 0 follow error
what can i do?
what is P for that axis?
P = 1000.000
that should be fine I think
what is [EMCMOT] PERIOD?
are you are using freqmod?
PERIOD = 0.000020
with that PERIOD you probably can't get over about 10000 pulses per second
when i increase that, my computer locks
what are your INPUT_SCALE and OUTPUT_SCALE
1250.0 0 (both)
when you set max_vel over 6 how many steps per second are you requesting?
~ 7000 microstep
I think you're limited by PERIOD here
what are SETUP_TIME and HOLD_TIME
SETUP_TIME = 1
you need more than (SETUP_TIME + HOLD_TIME) PERIODS per pulse
is it a very slow machine?
no, celeron 1800
but i run emc from livecd
can you reduce the number of microsteps per step in your driver?
yes but if i use 5000 microstep will be better
here's what you're up against
in [EMCIO] section, PLAT will be realtime?
no it should be nonrealtime
PERIOD of .000020 means your realtime motion controller task runs 50000 times a second
to change the state of the output you need 3 PERIODS because of SETUP_TIME and HOLD_TIME
you change state twice per pulse
that gives you an absolute maximum pulse rate of 8333 pulses per second
by requesting 7000 you are too close to that.
$ units 1/.000020/3/2
you have to decrease PERIOD (you can't) or reduce the number of pulses you need per second (change your microstepping mode)
hm, if that's the speed you can get with stepper driver's .. I guess I need one of the vital cards :)
cradek, thank you
cradek: can you have a faster rate if you have a faster computer?
but not much. the computer is pretty fast here.
what you need to do is change how far your axis moves per pulse
hm, I have a 500 atm.. for my mill...
but well, if everything works out I might gea 3ghz.. for it..
cradek: that takes away precision :/
or well, not with geckos..
my system moves at 25ipm and has resolution of 1/8000 inch
I would happily have 100ipm and 1/2000 inch
now you could try changing HOLD_TIME to 1
see if your drivers still work right
it will get you a little more speed.
but well, I dont know how my mill performs with emc.. yet
I am curious to see how the segmentqueue does..
when millint complex shapes..
anonimasu, remember. photos
wha? :) I wanna see end results. :)
I'll get photos once I get it to work as supposed..
the only thingk thats keeping me is that you cant redefine step/dir pins in the cfg..
* anonimasu craves for a cnc lathe atm
but I dont have time to build one :)
I wonder if the machine shop nearby would get me my parts.. if I sent em .igs of them,,
I'd like to have my bracket made today... I've got the metal, the hole bored.
I am stuck on my machine until I get my boring head..
just need to make the bolt slots, and tap the big hole.
to make better bearing mounts :)
I bought a boring head cheap on ebay.
I found a cheap boaring head at a company here...
it's a shitty boring head, but does the job.
uh, my boring head was maybe at most 1/5 of that.
50 USD with boring bars.
it's a cheap Made in China one...
does the job.
there's a ton of backlash in the head, but I'm only going in one direction, and I realize that I can push the head in... and index it from only one direction.
backlash in the incrementor.
Pita Wilson is hot.
Nikita on Nikita :)
she looks good.. but she's a tad bit old :p
[15:50:02] <A-L-P-H-A> http://www.imdb.com/name/nm0933959/?fr=c2l0ZT1kZnxteD0yMHxzZz0xfGxtPTIwMHx0dD1vbnxwbj0wfHE9cGl0YSB3aWxzbnxodG1sPTF8bm09b24_;fc=2;ft=21;fm=1
she's older than me by 9 years.
I hate my current bearing mounts..
14 years older then me ;)
they wrok and have good precision..
but I'd want em machined out of solid blocks of alu..
encapsulated.. and with nice lube points..
for automatic lubing..
mmmm ... automatic lubing
is Pita Wilson equipped with that?
robin_sz: I dont know.. if that was the case and if she did chew metal all day long I'd be scared.. :P
robin_sz, hmm... I would think so... she has a that's 3 yrs old.
a kid that's 3yrs old
I turned some of the most horrid stuff at friday at work..
at the large lathe..
it was some steel couplings for a tractor..
spark rain ;)
over 1m swing?
someone was telling me about a vertical lathe... that was war era vintage... and took out 1/2" chunks to rough it out... making horrible horrible noises, but just worked.
robin_sz: I've taken 1cm cuts at it ;)
how BLACK were the chips?
I assume you mean 1cm wide cuts
not 1cm deep
ie turned 2cm dia off a bar in one go
not 1cm chips
err 1cm.. that is..
err 0.5cm that is per side..
large ass russian lathe :)
what kind of cutter would you be using? tungstun carbide?
i'll take 2 to 3mm per side on the small colchester, but not with a fast feed
seco carbide inserts..
the inserts wont take much more abuse..
not much atleast..
I use seco or sandvik inserts
all seem good.
get em cheap on ebay
seco are good
I dont use coolant much these days either
have you seen their catalog?
it's 2dm thick..
or more then 2dm..
with all extra papers..
we got it at work..
they sell lots of special inserts..
and lots of types for different stuff..
well the part I turnd was nasty..
couldnt take more then 0.05 each pass..
could only clamp it at the edge..
anyone know anything about 802.1p vlan tagging?
I dont know what material it was really..
just some steel..
it was nastier then turning ballscrews..
ballscrews are just hardened...
it was a bitch to do mine
I turned mine at my small home lathe..
I ended up grinding it with a die grinder to get past the hardening.
I broke the insert but managed to get the hardening away..
it's work hardened, not treated I think.
I broke so many inserts... not even my tool.
I think it's surface hardened..
I brought over my tools, and they did it no problem.
he had _really_ cheap disposable tools.
they were horrible.
the reason the insert broke was because the toolpost flexed..
I would not want to machine ball screws again though.
I used the oxy-acet to heat em cherry red and then anneal
and started chattering when it went over the ridges..
really, you need a little grinder to do that
I'd turn em at work in one single pass.. to get the hardening away if I were to do it again..
robin_sz, no oxy-acet torch.
$friend has a little myford grinder, would have made a lovely job of them I think
I'll buy my next ballscrews pre-turned
he does some beautiful engineering work ... this is my gunsmith friend
highspeed grinder to get through the hardening?
* robin_sz nods
a toolpost grinder would work wonders
not on a lathe you value
must make a huge mess.
* robin_sz nods
I value my lathe...
even with guideway covers, it gets into the sump
I don't value his...
anyone know anyting baout 802.1p vlan tagging?
how's the router running?
hmmm ... seems my stp failover test proved it didnt work :)
anyone know how to convince a mandrake box NOT to use the gui as the default login?
if it has an /etc/inittab, you probably change the default runlevel
looking at it .. this is an old 2.2.18 BDI install
cradek: what do you recomend as a basis for trying the segmot stuff?
what do you mean?
debian fresh install? a BDI of dsome flavour
no no no, just update from cvs
I also use rtlinux
you don't have to screw up a working system
well, I doubt I can even remember the arcane incantations to compl=ile it ...
it's easy now
make plat=rtlinux_3_0 etc
then run make four times
in both the rcslib and the emc/src directories
leave your old emc alone
check out the cvs in a new spot
copy over your ini file
yeah, ages since I played with this ...
liek .. 18 months!
ah well, another dream shattered ::
no .configure file in the cvs head of emc or rcslib
cradek: are the .configure files distributed seperatley or somehting?
robin_z: not sure...
robin_z: just do it the old way then
probably make PLAT=rtlinux_3_0 and make PLAT=linux_2_2_18
hang on ... I'll just follow the README
I've never used the new configure in emc1
well, its not there, so it would be hard to ..
try those two makes in rcslib
the README was devoid of further clue anyway
/bin/sh: etags: command not found
yeah, justy suprised it even in there as standard
coo, rcslib built without exploding ..
so try the same in emc/src now
hmmm ... emc is building too .. .but lots of complaints about missing slocate
but, so far .. so good
seems the locate db is a bit old ... last time the box was switched on was in Jan 2003 :)
vital.c:49: pci/pci.h: No such file or directory
make: *** [/root/emc/plat/linux_2_2_18/lib/vital.o] Error 1
make: *** No rule to make target `objs', needed by `libs'.
robin_z: What install you working with?
install pciutils-devel pacakge
trying the current cvs head
Where did you get the linux you are working with?
this is dedrat/mandrake based from loooong ago, up2date support died a long time bac
rayh: a BDI of some flavour
Some of the BDI-2.xx series failed to install the pci utils package from the disk.
If you've still got the disk you could look in cdrom/redhat/rpms dir and find it.
well, I'll just delete the vital stuff from the makefile
rayh: is this supposed to build with a ./configure && make?
You'll also have to delete the vti stuff as well
or did it still not get that far?
There is nothing in the configure that looks for and stops the make of pci stuff.
theres no .configure even
I believe that was the other half of the problem we identified.
this is current cvs head ...
the configure stuff is in rcslib/etc
I used it yesterday here with rc46 and it worked well.
you did ./configure ?
in rcslib/etc yes.
thats an "interesting" place to keep it
My compile PC died the other day so I need to reinstall a 2.xx
Yea. fooled me for a while.
why is it not in rcslib/ ??
ok, I'll just put it down as 'another emc quirk'
'fraid you'll have to until someone explains why.
perhaps I'll commit a README for rcslib with that one fact in it.
ages since ive played with emc, quite fun again :
I think the huge expense of real controllers has driven me to investigate it again :)
remind me .. to run it now ive built it all ...
The current real-time platform appears to be rtlinux_ but no directory exists for this platform.
okay. there is an .rtxxx file in the emc directory. Remove that or edit it to read 3_0
I changed it to .rtlinux_3_0, it was .rtlinux_verion.
still doesnt work
Remove it entirely and run will ask for rtlinux version. Answer 3_0 only.
oh, that was a text entry?
that needs to be more obvious I think
It is gone on all the newer versions.
this IS the latest version
I was thinking of linux or bdi versions.
this is current cvs head
The file is needed by the rt that is working rather than the emc.
I seem to remember that it points to the numerical extension to the rcslib or some such.
well, generic run works .. :)
Great. That's with ./configure?
id already built the 'old way'
slowly its all coming back to me
im vaguely remembering what was wrong when I last used it
I seem to rememebr there was a bug relating to units ...
I run fairly low steps per mm, like 50
and quite high speeds, like 20m/minute
That should be gone in the current source.
I think that last year's fest took care of it.
I make that about 17khz pulses ..
so it shouldnt be a problem
I may just hook some steppers up to it right now ... like I say, its been a LONG time
How fast is the processor?
450 mhz or more.
Should be able to get close to 17k anyway.
easy I would hope
I was getting twice that out of a certain other system
I guess I'll go with servos eventually anyway,
I just wanted to checkout the steppersegmot stuff
see how smoooooth it is
power is kinda goin in and out here
build a generator
combined heat and power
go on ...
you know you want to
what's that stuff the trbine is made of?
just cheap old metal
you can buy 160hp turbines cheap enough
that sorta thing
ex-military power carts
its all done already
3 or 4k USD
surely you have contacts at a boneyard someplace?
sure do in Chicago
The big one is that airport where the sub orbital private rocket flight was done
Well I can't run the machine today due to flickering power
so designing that client's cnc foam cutter
25 meters long
Just doing the servo/transmissin on motioneering software
you know the free stuff
* robin_z nods
funny I am needing about 15:1 ratio on this one
seems ... low
a lot different from a plasma though
is it heavy?
light for it's size...moving mass about 700kg
I was offered a nice system with 300W ac servos
going for 1 foot/sec but high frivtion
seems a bit big for my 50kg gantry though
1 foot a second ...
100 in/sec^2 accel should be plenty
derate the motor 2:1
need to find a sourcr of racks
75 feet of them
well browning etc but they are not hardened
I use "halifax rack and screw" ..
but, they have a US division
Oh my lathe was made in Halifax
[19:10:58] <robin_z> http://www.hrs-ccl.co.uk/america_about.htm
what kind of price for that stuff?
like, 20mm wide, 5mm pitch ... 20 gbp/metre
[19:12:55] <robin_z> http://www.hrs-ccl.co.uk/images/gear_rack4.jpg
see those two racks ;)
theyll do whatever you want ..
hardened, painted, engraved with pictures of your grandma
at that price I could even used a larger derated unhardened one
as long as the pinion is hard
heres my philospohpy
1) its going to wear
2) make the pinion follow it
3) if dust is a problem, mount it upside down
...like lapped in gear sets
fortunately I don't need extreme accuracy or anti backlash
it's upholstery foam
cut by a round spiral bansaw blade
I don't have to build the thing...just rough in a design
This is that $100/hr billed engineering stuff
I can rough it in and do a sanity check for the guy for $500 or so
just a quicky worked in
this is a vertical bandsaw blade?
cuts in all directions though
ultra-high speed I guess
or the foam would sqish
im trying to imgaine how it fits around the Y axis
the only foam cutters I have seen look like meat saws
the ones ive seen look like hot wires :)
long 75 ft strips cut into shapes in 2d
this is urethane...does not melt
I am a bit reluctant about that
* robin_z nods
some industrial controller?
This is a non-technical guy
they have some nice HMIs
I have the inverted pyramid on the base of my cabinet now :)
some drop in black box
nah, add on
les: you could do wors than look at the Burny stuff
[19:23:42] <robin_z> http://www.burny.com/
have a look at the 1250+
not cheap, but user-proof :)
it even has "monkey node"
a prgram is sent over RS232 ...
the box beeps
is it rs 274 code?
display "1250 x 2500 1.6mm" on the display
the monkey loads the sheet and presses start
the program ends, and deletes itself to stop the monkey running it twice
sounds like the right kind of thing for this guy
but it can stor LOADS of programs
I thnk it has a couple of megs internal flash
or was it 500 megs
heh...keep it up and I shouls send you the retainer fee...
What will happen is that I will rough in the design...
he will build it
whatever .. theyre pretty idiot proof, and you get the servo drives built in
this would be ideal then
they will ship woth motor, gearboxes, cables
call me on the phone for mechanical how tos
and that's it
its literally unpack it and plug it in
but not cheap
If the guy can afford hiring engineers he can prob afford those
anyway a simple solution that he can put together is best
and .. they are the most common controller in the oxy/plasma shape cutting industry
If I had to go there and spend time it would cost as much as many controllers
so .. loads of engineers can setup and fix em
the invoice is in the post ;)
hows the ice storm?
trees are really starting to bend
was first sleet...no problem
power cables covered in ice?
now freezing rain
will it snow?
yes up to about 2 cm of ice on cables
as much as a foot of snow was predicted
but it is not happening
you seem to get an awful lot of ice storms Les, you should move north where it comes as nice fluffy snow!
10" snow = 1 " ice
yeah John...never had a problem in Chicago
is Rayh here, or just lurking?
prob has laptop by the grill cooking brats
I always kept cooking outside up there in the depths of winter
grill keeps you warm
do that here too
all cooked on cherry scraps
since I have TONS of them
Robin: I will call the Burny distributor tommorow I think
quite close by
les: kewl, nice kit.
So how much is the 1250?
add a zero?
mmm ... with servos and gearboxes ...
about that, yes, add a zero
might be better on your side of the pond though
with all that might be okay
better than me doing plant trips
which I cannot do anyway because I am booked
oh you could
IF the price was right
ahem...I charge ITW $1000 a day but I have to pay expenses
well, for twice that plaus expenses then :)
nah...I need to be here and be a turkey call spray painter for Mcdonald's wages
oh yeah :)
solved yer bottleneck?
what am I doing...????
dont ask me ...
actually I am doing ok...grossed $2000 this week but paid only $150 in wages
thats a,most reasonable
had a fixture failure that shut down sanding for a while
timed your sander guy?
I have him set up with a station using a dc servo motor and power supply
and a nice dust extract?
I think 5 min for two sandings
yup I added some duct to those sytations this week
hard work sticking things to the ceiling
need skyhooks :)
had three sandings
sand, seal, body coat, sand, finish coat
oops that is aftrer not before
so 5 minutes of sanding per item?
before sand, seal, sand, body, sand, finish
yes in total
so 12 units and hour max
perhaps a little les now
you need two sanders I reckon to match the output of the cnc
I think he is getting much faster than that
must time him again
I can do about 150 units a day with the cnc
at about 60% utilisation
but not doing that much now
doing about 100
sounds about right
that would max out at $3000/wk
the sander is the bottleneck
and the finisher
but not yet...
the finish process is quick though
because I have yet to use him a full 40 hr week
something somewhere isnt adding up
power is going...
you know what I'd do ... run that CNC hard for a week, build up a BIG stock of parts, theres no reason not to just convert ALL that cherry to parts, maybe no painting gets doen for a week, but your sander is fully occupied
then start painting
you can just concentrate on painting, because, even if no painted parts are ready for sand2, he has raw parts to sand
I think part of it is that I am a crappy production manager...
and as the paitne dones come through, he has even more to sand
True I started an ITW division but...
then they sent me to corpratr
yep .. just run that CNC hard for a week ..
for a lobotomy?
"people skilled at inventing products that sell should continue doing that"
Rather than forcing themselves into a business management role
They might be right I don't know
forcing? or being forced?
Actually I insisted at the time
Got something called a "fellowship"
where I was given a little office at corporate and left alone
did it involve a gold ring?
no but a very nice plastic and walnut plaque
nice gig if you can get one
But I still love manufacturing not inventing
perhaps I am not as good at running a manufacturing operation but I do like it
love to punch out those widgets
Aw, I always got stuck in r&d or product development
les_away: how are you guys doing the sanding? on a spindle rotating?
but I like assembly lines and making stuff
dan: yes...the spindle has a special chuck I made out of 1140 steel
hooked to a spare servo motor
hey ray. Brats done?
les_away: could you use a compliant abrasive wheel instead of a piece of sandpaper?
John I didn't see you.
Yep. Just had two for lunch.
been quiet... packing ebay stuff to ship
dan: Yes...but I like to preserve the crisp detail I get from the emc carving
I do wish I could do cnc sanding
les_away: could you put a pic of the piece up on the web somewhere?
but easier said than done
So the question is how do you deburr a carving without loosing detail
dan: I have not but will
have customer's web site though
les_away: I would like to look at it.
sanding drum same size as the cutter? (or are the cutters tiny?)
john, I have 6 tool changes mostly with formed tools...custom $75 router bits
(was visualizing straight end mills)

scroll down 1/4 way
and you will see an EMC made product
the crystal over slate call is one
les_away: semi circle w/ chamfered holes right?
has some interior details you can't see
les_away: break the sanding down into steps
les:automate what you can w/ a lathe and abrasive wheel
les_away: leave the detail to hand sanding
Am considering such
Turns out that things like automated sanding are the cutting edge
needs the human touch
it's a touchy feely thing that machines have a hard time doing
les_away: for finishing, use things that let the coating flow, (solvents, retarders)
knowing when the paper is starting to clog or wear out, etc
Mind you this is for a premium finish
A spit coat of unsaturated polyester like eveything else is easy
This is closer to an automotive quality finish
That's how I took all the production away from another supplier
It's all looks
yep, that sells
It's a Gestalt thing right
put the sander on piece rate?
wELL NAW HE IS DOING GREAT AND GETTING FASTER AND FASTER
hit cap lock
I didnt think automated sanding was that new..
the wood actually shine before any finish is applied
would it be impossible to build such a machine?
anon...it isn't...but a "piano" grade finish is another matter
very precise screws.. and some special tools..
could you use a vibratory finisher?
anaon: it would be a nice challenge
les_away: with special tool..
I mean a vibrating tool..
dan: thought aboutit
not one that circulates..
it could be done..
What we go for is the circular micro scratches that give a unique sheen
I thought about going 90o
or well less..
just flattening agent for example gives that "wood flavored formica" look
* rayh is starting the snowblower.
I dont know what that is
a sheen versus a raw gloss is a real subjctive thing
plastic laminate made to look like wood
hm, you could use a algorithm.. to detect the surface finish..
I need to do some grinding....be back later....
but well I might be speculating..
It's not unusual for my mind to wander..
Sorry that was the cnc foam cutter machine client
on the phone
I really have too many eggs in my basket
High performance cnc sanding is the cutting edge of technology for sure
want to work on something new...
les_away is now known as les
...until the next power bump
I'm a low tech guy. I'd use one of those grit impregnated flap wheels.
great for lots of stuff
but not 4" cherry hockey pucks that sell for $60 I guess
The customer loves the crisp detail that emc gives
flap wheels would soften that crisp detail in this particular shape
like the checkering on gunstocks...can't really be sanded much
or they will end up mush
how about CNC engraving - cut with sharp knives instead of rotating cutters, plenty of detail and no sanding needed
crisp sharp knife wood carving currently cannot be duplicated by a machine
the best carving is never sanded
considered a sin almost
isn't checkering engraved with a knife of sorts?
so craftsment do it rether than machines
kinda like curvelinear thread chasing on a surface
make a machine that could do that on any shape and you will be rich.
And on this big cnc machine I was just on the phone about...good case study. The guy really doesn't know what he wants or needs.
So ok...I will give him outrageous performance.
He will not be dissatified whatever he does
CIA-temp267 is now known as CIA-8
Will bump his machine up to 200 in/sec^2 accel
just a bigger servo really
but not huge
1500 in oz @ 1000 rpm...not too hard or pricey
CIA-temp909 is now known as CIA-7
yikes I am looking out the window at the forest haer
and some 50 ft tall tulip poplar saplings are bent double from the ice
won't have power much longer...
les : you have a fireplace right
I hope you dont lose power, but Im betting your in a better condition then what I would be in.
gezr: I have two airtight wood stoves
and three ng stoves that can run without electricity
so i'll be ok
But my grandma here (and an employee) live in places with electric heat pumps only...
so I may have some guests here
right now I am in the music room
might as well do some music as long as there is power...
the blast box is comming along nicely, I have the side door mounted, the window section cut out, its looking nicely
