Hi Skunk, how's WI tonite ?
good - how are you doing?
how is the mill running?
So far so good...
hot day today - all the snow is melting.
Yep, same here...maybe 40 ?
Had big chunks of Ice fall off the roof....
About 3 pm....
Thought I broke something, hi....
that will wake you up
Thinking about some sort of skirt for the table...to cover up the wires and things....
Also lost out on Ebay on the ER-20 tooling project...
Found a collet chuck with a solid shank I could turn down to 15 mm to fit the lathe....But to be sure I made a test piece turned between centers...
lost a on a bid or dead beat shipper?
Went to buy the chuck, and it was sold....should have got it, it was only $21.00 ...
had a few of them ;)
So, took the test piece and bored it out for the 5/16 ths boring bar....not a total loss in the end...the boring bar likes being in a big piece of steel, in the bar holder
, rather than in a vee groove holder....
I was able to drive the test bar with just the point of the headstock center, taking 10 mil cuts...
in drill rod...
what kinda lathe?
Its a schaublin 102, from about 1960 I think...the plaque is gone...
the older the better - we have a nice little monarche I like to use whenever I can.
Small enough to fit my space, big enough to do some good tooling work with....I did not buy the motor and vari-speed pullet with it....
Which actually weight more than the lathe!
I got a modern 2 HP three phase servo motor and had a custom flat pulley done....
The drive for the servo runs off 110 or 220 single phase, and internally generates the three phase for the motor....
;) sounds farmiliar - the monarch had a motor generator to make the dc to run the lathe motor. we went with a solid state control we had kicking around
That has to be the best deal I ve gotten on Ebay, that motor and drive....
The motor only weighs about 40 lbs...
who makes the drive?
It says MTS Systems on it...
I think the motor is a Emerson...the motor is about 5 inches square and 11 inches long, with a resolver on the back...the drive has a encoder simulated output from the resolver signal..
Holds speed quite welll...just run +/- 10 v into the drive control signal from a homemade control box...
I could eventually use it as an A drive for CNC lathe....
sounds nice - already to cnc ;)
The Schablin has big Tee slots down either side of the bed....
Its a tool-room / watchmakers style lathe...
Funky threading attachments, which I do not have....that will be the CNC project when I get to it...
Nice to have instantaneous reverse...can slide the tail stock with a tap in it, and go back and forth....
some one around here had emc working on a lathe
Also, especially nice having the full torque variable speed, being a lathe novice, keeps me out of trouble...
never keep the chuck key in the chuck ;)
Can spin the speed control to the middle and bring the thing to a stop in about 2 seconds....
Do not use chucks...just collets and faceplates...that s the drawback of this lathe,,,hard to get a chuck backplate for it....
has a funky metric threaded head stock nose....very close to 1 1/2 by 8, but not quite....its even odd for metric, not even metric diameter or pitch...
[02:10:28] <skunkworks> http://www.emachinetool.com/used/catalog/vertical.cfm?DestinationCategory=Engine+Lathe&ProductID=11115
pretty close to ours - looks a little nicer ;)
actually ours it a bit bigger - around 2 inch through the spindle.
Looking for a good picture of the 102...looks like that machine-tool thing has been severly concatenated...
Can t find a good picture of one like mine....
But did find that www.lathes.co.uk is still there...
built a custom table for it with a maple top and 8020 frame....rather than the original which on this one was cast-iron plates that bolted together....
This lathe is only 14 mm through the collet ID, but there are various collets available that are larger...I have up to 1 inch here...
But, still only 14 mm through the smallest ID of the larger collets...
These lathes, the smaller 70 and this one also have the F style headstock, for fixed length chucking....
I have a 70 with the F head stock at work...
Been looking at the TP stuff people have been talking about.....
Very complicated problem, even without the programming issues...
a little above my head
I do some of the coeficient curve matching at work...but usually manually, as its so unwieldy to keep from doing all sorts of dips and doodles...
Move a point a little bit, and the resulting coeficients generate a curve which goes shooting off one way to end up hiting a point two or three points down the cureve!
But, I am messing with 5 or 6 th order curves...
So, I end up tweaking my measured points until I get something that is smooth ...
For what I m doing I can increase any of the points a little, but not decrease them....

Been raining a bit for a few days. nothing extreme
its been very quiet on this list the last few days.....
eh, probably due to christmas
chasing the turkey! or in Les's case the chicken }
no, the chicken follows the cat/dog

nice looking chicken
the cat and the dog are it's only friends.
yea.... Les has told some good stories about that chicken
I think it's cool.

morning robin_z :-)
it would be
* Jacky^ is waking up with a good coffee
need a very strong coffe to stay awake until 3 am
have a cool jule... abbia un fresco....?
anyone know what it mean ?
where was I?
morning Martin ;)
how's it going?
I feel feable. I don't even know what language that is.
so how goes it?
hey, while you are on ... pipe welding question :)
I need to make a filter container, 200mm AS105 pipe, 6mm wall, welded to some 10mm flanges
its only 10bar pressure so nothing too serious
how many pipes?
just one pipe, with a flange at each end
any special position you need to use?
so, weld prep the pipe end with a chamfer
can you rotate the pipe?
yes, for 6 mm I'd use a half-Y joint
first pass WIG
then MIG for the filling
pipes are always welded WIG for the root pass, gives you the best results
TIG, sorry ;)
Wolfram = Tungsten
and do it in 90 degree sections
or one continuous pass?
Ideally you'd place the tip at one a clock, and rotate the pipe
continous pass is OK if you can tilt it up, having the flange horizontally
aj, don't you have robots for that?
anything else will require a very skilled welder
A-L-P-H-A: I have, and I use robots for that.. but robin doesn't
at least not yet
I thought there was some issue with if you welded in one pass round a pipe it had lots of stress at the end point?
robin_z: not very much, at 6 mm wall it might be ok
if you are concearned, preheat it to say 200 degrees C
and let it cool down slowly afterwards
and are flanges normally id = tube id?
or id = tube od?
hardcore... what's the pipe for?
didn't get that
the hole in the flange ...
is it normally so the tub sits inside it
or tube its on top of it?
well.. let's take it this way:
you want liquid to travel through the pipe
mmm, no :)
so there should be minimal disturbances in the flow direction
or gas, whatever
its going to have end caps
its basically a pressure vessel, with ends
then it won't matter much
but the flanges I've seen are all aligned to the id of the tube
i'll go pipe od = f;ange id
pipe id = flange id
and they sit side by side
thats what I meant to type :)
but if you can do flange id = tube od then you might be able to weld from both sides, and have the flange sit on the pipe
the problem is what you want to connect to the flange, if it's a flat plate, then maybe it's not such a good idea
this is for the the filter stack on my nitrogen generator project :)
if you say :P
robin_z?? are you making a pipebomb?
anyways.. use half-Y chamfer
on the pipe
and the flange as it is
maybe 1-2 mm for the straight Y section, and about 60-65 degs for the angle
basically, its just a big tube full of carbon, air at 10 bar passing through
* robin_z nods
and tack it with 1-1.5 mm space to the flange
then use TIG to weld the root
ok, we have tig
that should give you the best results
I could even TIG from the inside ...
infact that would be a lot easier
usually you use a "finger" mill on the inside after the weld,
as I say, no flow as its endcapped with a plate
so no problem there
ok, then you probably don't care much ;)
10 bar should be trivial
I just dont want it to fly off as it comes up to pressure :)
if it were > 500 bar with steam inside, a bit more trouble
your worst welding won't make it fly off at 10 bar
it'll leak, and crack, but certainly not fly off (imho :P)
ive only recently read up on nitorgen generation ... its so simple ...
you just let the carbon suck up the oxygen at 10 bar ... so you get oxygen free air (mostly N2, plus a little Ar) out ...
whne the carbon is saturated, just lower to 1.5bar and back flush,
out comes the oxygen again .. repeat as required
I wish good parties to everybody you
robin_z: repeat till you're dead, if you're inside
hey ciao :)
I was in the shower (bath) one time at year I do it
have a nice christmas
bye alex_joni have a nice time

Buon Natale a tutti
happy born to everybody
rayh: happy born
you do the dinners of native this evening? rayh ?
Yes we are driving to visit friends and will have dinner. You also?
I go my sister
we hope you come soon the evening and these days!
Great. Family is important.
Hey Ray...still there ?
Anybody familiar with Matt Shaver's BMP2CNC utility ?
I used bmp2cnc once.
Think I figured out what I was doing wrong for a start...the distribution has an EXE which apparently is only ment for windows...
I don't remember what all the args were for it.
I remember starting it from a command line and passing the file name.
But in general, how does one run a program from linux console? Or how does linux know a file is a command ?
Also, apparently an Italian company has come out with a GUI program that has the same name, and does the same thing, but with some nice added functionality...
wb9mjn: it knows by the file permissions
So, if you have a file, one knows is a program file, one could go in and edit the permissions ?
They do not get set automatically by extension type ?
no, there is nothing special about the . character
so there is no such thing as file extensions
you can of course name a file file.abc but that means nothing special
So, if one gets a distribution of a program package that is to be installed manually, how would one know which file to set to be the executable ?
it's not a sure thing, but the distribution will probably already have the permissions set properly on the files
anything used to archive files together (such as tar) preserves permissions
if you don't know what a file is, you can use the command "file" to "peek inside" and see
% file image
image: JPEG image data, JFIF standard 1.01, aspect ratio, "CREATOR: XV Version 3.10a Rev: ", 1 x 1
Ok...maybe uncompressing it in windows is where I went worng ?
wb9mjn: quite likely, windows is known to screw up permissions, upper/lowercase, extensions, etc.
because it has completely different rules
In the windows file system no file permissions, so when I copied over it was devoid of permissions...
hello all... merry christmass to all... ;)
OK...i ll untar it linux and see which files pop up with the executable permissions....
great, that'll probably do the right thing
seemed wierd that they would only put in a windows executable, and not a linux one, when the package was originally done on linux...
yes, I agree that sounds strange.
maybe it's not actually written on linux.
I ll go look at it some more...
often on linux (with open source software), you get the source and compile it to make an executable custom for your system
on windows, you don't usually get the source for stuff, only an executable you can't change
Yes, it includes the source....
i have DOS executables ive been trying to make work in linux for a few yrs now... to no avail...originally come from an IBM 360 mainframe
maybe you're just expected to compile it then, and there is no linux executable
there are several ways to run dos programs on linux
dosemu and qemu pop to mind
I run Autocad for dos on linux under qemu (using FreeDOS)
well this post processor needs a particular version of dos to be reported to the exe at some point
I m on a windows system here, and the linux is on the machine in the other room...I can network the results back and forth...now that I can run it...but would be nice to have it work
on linux too...
off to lunch....
cradek wanna jive APT a kick??
Automatically programmed tool
no idea what that is
toolt goes on line 1 tp plane1 in z at feed of 10 ipm
dmess: sounds interesting, but no thanks
its an associative programming system
i can only make it run on a 386 or less...
dmess: did you say you had the source code?
dmess: I'll sell you my AT
no i wish.. its available through nist...
cradek is an antique computer collector :)
i have a few 486dx it works on...
dmess: it's a kick-ass AT, 3 MB of ram and EGA
you can post the apt in win 98... but it wont post... it MUST post to g-code on the old box for some reason
i wanna set up a post box email addy.... send in apt cl file... get g-gode back in your in-box
post process.... into g-codes for ANY machine once we have the post built
APT is a very high level programming language... it needs to be post processed( flavoured ) for the actual machine it will be run on
anything you can do in FORTRAN is available within the machine tool programming environment in verbose text format
full 5 -axis programming.... its cool.. but old fashioned..
mills a sqauare 100mm sq
works on drive surface , part surface , check surface.. iterative principle... set to intol/outtol (inside material tolerance/ ouside material tol)
nops = no part surface
psis = part surface is
indirv = in direction of vector
tlrgt = tool right
golft = go left
no classifier in front of a geometrit element implies a "TO"
happy dinner to all !

when anyone called in i was the GOTO guy

just wanted to let you know the acceleration fix you added is working. When you get a chance though could you run your machine at g0 and hit an estop (f1). When I get it out of estop and back on I get following errors that shut the machine back off. According to the bug report I thought it was fixed. or this is a little differnet
Merry Christmas (eve) all :-)
my son bought me a new Jonny cash cd....i think i love him again...
boy named Sue... i love it.. 1 piece at a time....
jepler: are you around?
alex_joni ask him afrer dinner
ain't it a bit early for that?
oh no.... almost 1600 in Calif
like I said.. a bit early
does that start at 1600?
could start at 1400 even
depends on your tradition
buffet style where you eat a lil all day long, or everyone sits for one huge meal
right.. over here it's usually after 1900
well, the early dinner I suspect is to get out of the kitchen bfore 0200
so.. what are you planning?
turkey breast, sweet potoatoes, stuffing, cranberries
the traditionals.. nice
almost the same over here :D
it wasn't very good for soem reason
no clue either... nothing that we haven't had/made/ate before.
should gine with the pork roast slow cooked on the grill =)
tasty stuff =)
