Re: Bevel and pinion gear cutting

Re: Casting HDPE - Introduction

Heck. I will not even put food in a plastic anything to warm it in my microwave..... Excellent advice Bill !.

Re: Best Tap and Dies for 303, 316 Stainless Steel

Learned that from a precision job shop who only did Stainless steel work. It is "the" goto lube in my shop https://www.mcmaster.com/anchorlube-tap...
