hm, it takes a fair bit of time to build the docs... much more than doubles the build time, I think
especially now that it builds html too
2:10 real to build the docs on a 1.5GHz machine
uh oh, and a second run of 'make' is making more stuff...
that'll never do...
jepler_ is now known as jepler
configure: WARNING: no latex2html, documentation will not be built
what package is that part of?
'apt-file search latex2html'
apt-file: command not found
'apt-get install apt-file'
in this case looks like the package name is more obvious than you'd expect
I believe that package is latex2html, but its not in one of the reps I have selected
is it in multiverse maybe?
that explains it
I think it's great we're getting html docs
I need a bigger bench
(or less crap on the bench I have)
nah you need another bench
need to use the surface plate, but no place to put it
a surface plate is sort of like a bench...
I am _not_ gonna hunch over and use it on the floor (where it is sitting right now)
just put legs on it :-)
hmm, if I move the crap thats piled on the computer sitting next to the bench, the plate would sit on that
pickup tailgate? I've been known to use that as a workbench
tower case ~= legs for surface plate?
I'm in the basement, not the garage
I decided something yesterday - I'm not building any more of these jigs, at any price
I see the fun is sure gone for you, so that's a good decision
dang! I forgot how heavy 12" x 18" x 4" granite is
yeah I was wondering about that
maybe the floor's not so bad
its up there now
what a pain
measuring center-to-center distance of worm and gear
how do you know when they're meshed right to measure?
worm is sitting in a vblock
gear is sitting on top
measure top of gear with height gage, subtract half of gear diameter to get gear centerline height
oh so they're fully meshed, you don't have to carefully pick a depth like with involute gears
them measure top of worm, subtract half of worm diameter
the gear was cut with a hob that is made of the same threaded rod I used for the worm
so they mesh perfectly
I'll make the hole in the housing for the worm about 0.001-0.002 away from "perfect", better a little slop than binding
I also have to measure the other dimension, parallel to the gear shaft
because the hobbed worm teeth aren't perfectly centered in the gear blank
not sure I remember how to do that
oh I see, they're wherever you hobbed them
close, but not perfect
so I gotta position the worm hole in two dimensions
is the worm narrower than the gear? you could put both sides of the gear on the surface plate and measure up to the worm's shaft, then do some math
gear is wider
and permanently attached to a shaft that sticks out both ends
that can stick off the edge of the plate
I seem to recall using small clamps to clamp the worm meshed to the gear
then measured the step from side of gear to OD of worm
I also forgot how much I like reading vernier scales
I think they're cool
yeah, they are
a "clever hack"
but no fun when you need a magnifier to see them
at least the height gage can be locked, then picked up to read it
I'd hate to have a vernier caliper (nice to have as a piece of fine craftsmanship, but not as an everyday tool)
yeah a dial is nice.
well I didn't do too bad on the gears
pretty well centered?
design center-to-center = 1.154, my two gears are 1.158 and 1.1575
I haven't done the other measurement yet
(centering of worm in gear blank)
one gear hobbed 0.012 from center of blank, the other 0.008
