Hello!
New to kitless pens and have fallen at the first hurdle. In the process of making my first section I noticed my 7.3mm drill bit was making a 7.9mm hole on entering the material, and after drilling through about 2 inches of material the exit hole is about 7.4mm.
I tried aligning my lathe (nova comet II) but the issue remains, I'm not sure what the next steps would be, and have no machining experience. Any suggestions?
I'm using a collet chuck to hold the material, and a centre drill to start the hole, if it matters.
Many thanks
