Steel Guitar Builder

Run the reamer pretty slow, maybe 500 rpm or so, well slower than drilling and be sure to use some cutting oil. Have you mic'd the bearings to be sure they are spot on .5"?

Teaching yourself the machining as you go...great job! You will want a press fit, not too tight as it can affect the bearing performance. Best to do some testers to be sure but I'd be looking for a .001"-.0015" interference fit. Can't do that with drills of course, you will need to use a boring head...

Neither of those plastic materials is strong enough for this application without a lot of extra material that you probably won't have room for.

Good Job Storm!

Thanks Paul, got it.

Don't despair Maxi, some of us are still plugging away...here's a teaser pic from the two I'm working on now.

Nicely done! Looking forward to seeing your progress.

Another beauty! I love red guitars. Kudos Pat

Good or Bad idea, I can't say for sure, but I used them in one of the pivots on my changer finger assembly and they worked great for me.

Note: I don't feel they negate the need for occasional oiling.

Google is your friend, plenty of info out there including how to split without this allen screws behind the changer.
