i was eyeballing a EDM for a bit but unfortunatly dont have enough floorspace right now, another problem is that most EDMs require 3phase current which i dont have out here.
There are some benchtop type hansved edms on ebay every once in a while.
Another issue it that you need to have a electrode that resembles the form of the gear made of graphite or copper and usually those are CNC machined parts

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
