1. Testing Lifters? (score: 1): Author: Rikrock@aol.com; Date: Mon, 2 Jan 2006 21:50:52 EST; I would like to test a batch of new lifters and I have some questions about the process...

Nothing in between. Flat is good, domed is bad. Flat rotates, domed or dished stalls and wears. The new l; /html/fot/2006-01/msg00080.html (7,916 bytes)
