Topic tags/keywords: drift

I was watching (http://www.youtube.com/watch?v=wGbZqWac0jU) “Band Saw Clinic with Alex Snodgrass ” On youtube.

This video was suggestion on here. Alex says that when your BS is set up correctly one should NEVER have to worry about/adjust for BLADE DRIFT when saw specially RESAWING.

SO I must assume if one is having to use a RESAW Table with a PIN in it you have NOT set up your saw correctly?

I set up my 14” delta as shown in this video, and I agree with Snodgrass. This is the only way I’ve set up my saw (only been woodworking a few years), and I have never had drift as long as the blade was sharp, and I’m using an appropriate feed rate.

I think it depends on the machine. Some saws will tend to drift as the blade dulls, even when properly setup. I usually rough cut at the bandsaw, then finish with the router or oss.
However for resawing, accuracy matters a little more.

Any bandsaw will drift if:
1. The blade is dull
2. The guides are not setup properly -(too much air space from the blade, or teeth back into the bearings)
3. The blade is not tensioned properly.
4. On some saws, the simple process of having the uppers too high off the work will allow the blade to drift.
5. Bad weld on the blade.
6. You are overloading the blade. (pushing the wood through too fast)

I agree drift = dull blade or too fast a feed rate.

A bad blade or improper setup is the cause of drift. Fix those issues and the problem goes away. You should never use a resaw finger or pin for straight cuts as that’s slow, inaccurate and a waste of time and wood. A regular fence works best.

Also, if you’re grunting while shoving the board into the blade, it’s a sign the blade is too dull. It should be possible to push the board through without leaning into the cut.
