Hey guys. 2 Questions:


1. Should drill rod be oversized when you buy it? I got some from Speedy Metals, W-1 5/16" and it measures .3138.... this is really annoying because I have to turn it down to fit a bearing/ gear.

2. I need a grease that is compatible with nylon. I have some plastic bevel gears, I don't want to run them dry. RPM range is between 1000-3000.
