I am looking for some help please. I was running a job last night that didn't go as well as I thought it would. I need to make 64 oil impregnated bronze bushings, 1/2" od, .376 / .377 id and 1.83" long. I had faced the ends to length, and was planning on drilling and reaming the id then putting the parts on a mandrel to turn the od concentric to the id. However, after just a few parts, the reamed hole was already undersize and I thought the bronze would be a no brainer to do! I was drilling the hole at 23/64 and was reaming at 400 rpm 5"/min feed and a quick retract. If anyone has any suggestions I would appreciate it because I have to deliver this job today.
