I just recieved one of the 2 grail parts I have been hunting for

it was not cheap but now I have it....
(why did I not decide to collect something easy ...like Bianchi!)

Asking for a Puch Panto stem, with the correct length is very much like
beggers cant be choosers.

Well now.. I have this tasty morsel If I only had a pantograph or if we knew sombody who did.
I could make a few more stems for others or my other PUCH.

The guy in Australia who sells decals on ebay, Cyclomondo, does pantographing.

For example:

That was my thought, too...but it's a long trip from Finland to Australia. You might need to supply him with a pattern to follow...or...
Back when I was a youth I worked in a shop that included an "artisan" who used a pantograph machine to engrave trophies and plaques.
One day a cyclist came in to have a stem engraved, which our "artisan" had never attempted, but he was game to try it. He had to send out to a die-maker to have a brass "master" plate made to fit in the "tracer" end of his panto machine. He made a mess of it, mainly because he couldn't/didn't clamp the stem securely and it slipped during the engraving. The cyclist was furious, but the "artisan" just shrugged it off...that stem didn't mean anything to him!
Moral: you may find a local engraver (like a trophy shop) who might be able to do this job, but if you have any doubts about his abilities...run away!
Another thought: I used to do acid etching on (mainly brass and copper) and made a few custom headbadges back in my miss-spent youth. This doesn't require any fancy equipment, but you really have to be meticulous in coating everything completely with asphaltum or the acid will etch things you don't want etched...and can't really put that metal back!

I doubt you will find anybody with a pantograph machine willing to take on that job (at least not for less than a considerable amount of money). Or unless they actually have the original pattern (some shop in Europe might?). You would be better off looking for somebody with a small CNC mill or router, perferably hobbiest that will work with you. That way the design only has to be done on the computer and then can be cut right on the part.

The hard part will be making a fixture to hold a stem in the machine with enough rigidity, but maybe you can make that part for them (as it will take hours of work).

Like the story above shows, I do not think people realize how rigid a fixture you need to properly mill and odd shaped piece like a stem. And a pantograph machine is not an ideal tool to do it (without modifications). It's why a lot of the period pantograph parts are so rough and ragged. I mill flutes on stems all the time and took many attempts at making holding fixtures rigid enough to get nice clean cuts. Especially using a ball-end mills which want to "dance" all over parts like that.

Never dealt with them, they don't list proper pantographing, but have other services:

I was thinking of making a post the size of the handlebar from solid steel, by clamping the stem on the post and the post on the milling machine it is pretty sturdy.
but I nother that the pantowork is evenly deep matching the slight taper of the part- so this was not the method they used originally.

It would be nice to have an old panto machine- 800 will get you one and then you need to make the patterns.

good small business for someone like drillium revoloution.
