So I've been doing a ton of reading on aligning my new Delta T2 fence (Biesemeyer clone) and I've read in a handful of places that you want the rear of the fence to be about .020" farther away from the blade than the front of the fence. I assume this is to prevent kickback from occurring via the wood pinching between the blade and the fence. I've currently got the rear about .015" farther away from the blade, should I to dial this in tighter or push it out farther from the blade?
