VCho455,

I have considered making a sleeve, it definitely wouldn’t be easy to bore just #4 and keep it all within tolerances for alignment to the other bores, but would allow the use of standard bearings.

Shiny,

I looked through the Dura-Bond catalog. They have a list in order by OD. Nothing close enough to make work.

I have a single .010 bearing on the way. Thanks PAUL K!

I have to make a mandrel to grind the OD to fit my bore vs boring my block for the .010 bearing. Since I have make the mandrel anyway, I’m gonna try to knurl the OD of a standard bearing just out of curiosity.

Thanks all!
