When I knew an HP mechanical engineer in the early 80's,
the division he worked in either picked gears from another
HP instrument, or had them speced, and they were contracted
out, his SPC and Boston Gear catalog was well worn :)
EDM is fun :) a co worker and I wanted 'wasted' a lot of time
seeing what it would take and cost to make a batch of LEGO bricks
we came very close to having a mold made, until this spring I still
had the 100lbs of brown ABS pellets. A short life mold, some glass
filled engineering material from GE instead of delrin
()
? and maybe end up with a truly life time gear.
I envy those that have room for a mechanical shop :)

Hi Pete,
That gear may be a problem. I cannot say that I have ever
noticed that one... or if I did, it probably scared me so much
that I put it out of my mind ;-)
The only economical way of making it would be to cast it out of
some plastic... probably a metal loaded epoxy would do. I'll have
to check Boston Gear and see if they by some chance have such a
gear set. I doubt that HP had it custom made.
I've been planning to add an EDM machine to my machine shop. Making
an injection mold for this gear might be reason enough.

I'm sorry this has gone this way, I just offered to buy
the junker and if someone lived in Reno could pick it up
strip it keep the rest of it if they wanted to,
and send someone like Chuck or a retired mechanical
engineer I know draw up a set of plans then give them to
someone with a hobber, Then post the details on mfg.com and
maybe a Chinese shop would surprise us with the cost.
There's just one gear thats not a simple one, Fig 5 near
the bottom of the page
