is there anyway to get these pieces still iv been looking for a while now and cant seem to find any out there

Yes, you can 3d printer both the cam and the gear rack. There's probably someone local to you who can print them for you. Nylon or ABS are probably what you'll want them to use as the printing material. If you need the cam I know Richard still has some 3d printed ones for sale at a good price, so I recommend talking to him if that's what you need.

Even the sales person told me that the sintering process was overkill for this application.

He said that the real value in that process was in parts that have interior cavities that are impossible to Machine. I'd be curious to see what a machinist would charge just for grins. I can't imagine imagine that it would cost that much.

Check this out.

Watch all his videos. I bet he can make what is needed as long as he has a sample or a print. This guy is really cool. My grandfathers wood working business never was steam powered or had the overhead shafts but a bunch of the machines did have flat leather belts and I have fixed more than one of them as described in one of his videos.

John, Dave Richards may be interested in doing this. Right up his alley.
(LOVE that shop, and with the new steam engine, looks even better.)

Another person to ask, would be Keith Rucker. No steam powered shop,
but he DOES drive the museum's #7 Vulcan around.

I AM VERY HAPPY with the ones i got from you did a good job.

It is nice to know that aftermarket metal parts are available when the original plastic parts go bad. My thanks to the guys who figure out the machining. The speed control on my father's Mark VII is working fine so I will not fiddle with it.

I have a full machine shop. I made a replacement on my CNC. From start to finish I was in to it about 6 hours, including design and programming the CNC. There was some hand fitting so my model wasn't perfect. If I were cutting a batch of 10 they would cost around $200 on the high side. But I'm not really a production shop as I mainly make complicated aircraft parts so charge a premium.

For my replacement rack I cut a piece of off the shelf gear rack from McMaster Carr that was $50 and took about 2 hours to machine the holes and cut the back to accept the diameter of the tubes.

Hi Richard --

I was just checking if you have or know where I can get the speed control cam.

Wishing you the best
Bruce

Richard's 3d file for both the cam and the racks are available in the file section of the shopsmith Facebook owners group page. I recommend you print it, or have it printed, in either nylon or abs.

I bought a cam from houseofrust at the beginning of January 2021. Printed in PETG. No issues so far. Much easier than making it myself.
