Tamiya 19mm Rollers - Almost There

Busy day today at home. We hosted steamboat lunch and dinner at home for my wife's family and mine. I sneaked into the workshop in the afternoon to figure out how to use the centering indicator I bought many years back. This round, I managed to figure it out.

I sought for suggestions and help over at MetalworkingFun forum. Those guys there are just superb! Suggestions poured in and with so much patience! Very friendly bunch of people. The thought of using double sided tape came to my mind when a gentlemen the spoke about using some kind of tar to hold the rollers while machining. Bought a big roll of "super sticky double sided tape" from Horme after dropping my colleague off yesterday. This round, the roller didn't move! One problem down. The next to figure out is how to zero my part more accurately. Check out the pics of the finished rollers and you'll know why.

Centering the roller using the centering indicator. Lim dialing in to the fixture which was turned in one setup. So I would assume that the nip holding the inside of the roller is concentric with the turned OD of the fixture.

After zero'ing the axes.

The actual cutting job was completed very quickly.

The double sided tape after the part being removed.

After some cleaning up. Much nicer than the first piece I did.

I'm quite happy with the result from the 2nd attempt. Closer inspection of the part revealed that I may not have found the exact zero of the axes though I'm very close. I'll do the next 5 and submit for testing before moving to the next spoke design.

My dad has also commissioned me to make a batch of stainless steel bushings for his dispenser. I'd the CAD done last night and should be able to machine a test piece next week to check fit.

Be blessed!
