Ditto,

If your turning down the back guy currently to .375", you might as well save yourself time and just lathe it down to .500".

I know it might be lighter to go that smaller bearing but honestly, its much easier programming/making 2 of the same part then it is 2 different parts.

Adrian,

We do about the same thing, buy .375" OD Tube with a .235" ID. 1658T41 - McMaster. We go parting crazy and you can make a lot of spacers in no time, especially on a bar feed . We use this material for the gearboxes we make. Do you really need the cbores? We've noticed its incredibly harder to assemble gearboxes that way.
