need your help Determining the correct wheel size for

I didn't get the 'Jo Blocks' at the 5 & 10, that's where I got the cheap squares that turned out not to actually be square. My good squares and Jo Blocks, from my tech school days, were in the process of being shipped from one end of the country to the other at the time.

My dad had been a tool and die maker at a major shipyard, and got a couple of sets of Starrett Jo Blocks at a bit above cost through a company program. When I started tech school he gave me a set, which some 50+ years later I still have.

Len;
Yeah, the tools I acquired are quite old-my guess would be in the 50-75 year-old arena.  I do not know if they "don't make 'em like they used to" stands here or not, but they are great, accurate, and hold a 'set'.
There are two other 'tools' I find useful to the nines:  Modern math and sticking to a plan. 
If there is anything that has kept my 'mind' in decent operating order, it would have to be those two critters.  Bourbon surely hadn't...
