Topic tags/keywords: tablesaw question

Recently I noticed that when ripping a board on my TS (Ridgid TS3650), the outfeed end draws away from the fence. The piece is still to size, straight, and square but it bothers me that this happens. I actually can’t tell you if this just started or has been going on for awhile. I just noticed it the other day. Like I said, the ripped pieces turn out just fine. Any help out there? bbqKing.

I don’t know if it’s true or not, but I read a posting a while back that said fences are supposed to slant very slightly away from the blade near the back of the saw to help avoid pinching the blade.

I think these things are hard to diagnose without physically being there and seeing whats going on, you don’t say how far from the fence, and there are several reasons that it could doing what you describe, The fence out of alignment, the arbor out of alignment or the board has a very slight curve to it, or your being too picky. Charlie I think is correct also.

Charlie is correct in that one school of thought advocates setting the rear of the fence away from the blade but this should be no more 0.003” which I know I would have trouble seeing. When I set mine I use a dial indicator.

The only thing I could think of is that your rip fence is not aligned to the sawblade or it is bowed.

Any chance you could post a picture of this the next time you are ripping a board?

There was a nice article in American Woodworker magazine (October 2006) on adjusting a tablesaw. The best such article I have read.

I think you could have one of two issues. Your wood is reacting and the way to tell that would be to make a partial rip, stop the saw, withdraw the board and see if the kerf is closing up. What I think is that you most likely have a misaligned fence. I don’t buy the advice about having the back of the fence kicked out from the blade. All you would be doing is rubbing your board on the other side of the back of the blade. My advice would be to get it as close to parallel as you can and then use a splitter. That should prevent burning and kickback.

I would say it’s reaction wood or case hardening of wood that is releaving some internal pressures.

If I notice that I then usually cut the piece big, let it react for a few days and then trim to the correct size.

Steve Naslund has a good plan. I would go one step further and cut a piece of engineered lumber (i.e. plywood) which is dimensionally stable. If the plywood walks away from the fence then you definitely have something misaligned.

I too do not believe it necessary to purposely misalign the fence by .003”. Small temperature changes in your shop can cause parts on your saw to move by thousandths of an inch. Unless you are in a climate controlled shop, shoot for parallel.
