I need to drill a hole which will house a ball bearing in a piece of 12L14 steel. I would like the hole to be 1.124" +0 -.0005. I usually use a reamer for a precise hole, but I didn't find a reamer that large and anyway large reamers are very expensive. The only way I can think to do this is with a boring head. But, I don't have an inside micrometer and can't find gage pins the right size. I thought of using 2 gage pins next to each other whose diameters add to 1.124". I also thought about making a gage pin. Any suggestions would be appreciated.
