I am trying to build a collet for my Dremel-like tool. My problem is getting the 1/8" bore true. On larger pieces I drill, bore, then ream to size. This is way too small for any boring bar or tool I have. The first one I tried to build, I drilled then reamed to size. It was way off. I thought of a mandrel but again the small size presented itself.
If when drilling the hole one were to stop several times and rechuck the drill bit in different positions, would that maybe even out the bore?
How do you get a true bore?
