This test block is useful if you want to make a holder for cylindrical objects, and you want to find the appropriate "fit" (not too tight, not too loose).

I prepared this test block in preparation for another project, and I thought others might find it useful. It just a bunch of holes in 1/4 inch, 3/8 inch and 1/2 inch sizes, with variations of +.01", +.02", -.01", and -.02". The tops of all holes have a slight chamfer.
