Topic tags/keywords: biesemeyer fence unisaw

I’m almost done reassembling my new/old unisaw and today i put the front rail of the biesemeyer fence on the saw but noticed that it slides on the table top and catches in the miter slots. Did I do something wrong? Is there a vertical adjustment?

You may need to file the laminate on the fence face. The only vertical adj. would be to raise the rail. The bies has a very close tolerance at the table surface, but filing abevel will usually minimize the mitre slot catching.

It may be similar to the Delta T2. Turn the fence upside down and see if there are holes that allow access to about 6 nuts inside the tube. Loosening the nuts allows the outside edges of the fence to be adjusted up or down.

I had that problem on a Grizzly saw and had to raise the fence about the thickness of a piece of notebook paper. All was well then.

I had to remove about 3/4” from the glide strip underneath.

Mine does the same thing. It’s an older one with aluminum faces so i can’t file it. I’ll try adjusting it up a little and see if that helps. Thanks guys.

ajoseph I didn’t think about that. I checked to see if there were height adjustments on the fence itself but not on the tube. Good idea. I’ll take a look today. If not I think there is some play maybe a 64th of an inch in the rail.

I have a Delta fence but it looks like a Biesmeyer T-square. I just got the saw a couple of weeks ago. It was in pieces, I put it back together without even a picture of what it was supposed to look like. It all worked out pretty good, but the fence was dragging on the miter slots a little but no big deal. Anyway, I had noticed two nylon screws on the t-bar but I didn’t pay any attention to them. I just looked and they are jack screws. I turned them just a little, and now it slides like glass. And I just now thought of tapping the bottom of the front rail, in several places, to make sure all the bolt slop is in the same direction. I’ll go do that now, and probably adjust it back to where it was. I actually bet that was my problem to start with. Bolt holes usually have a little play in them, you have to push it all in the same direction to get it even. Gravity will make the front rail sag as you bolt it on. That may be enough to make the fence sit too low. Three or four light taps across the bottom, should make it all level, and then you should be able adjust the fence perfectly. Mine was easy as soon as I actually looked at what those two little screws were for. I knew better, but I guess I like to torture myself sometimes, too. It should be an easy fix.

Randy: The nylon adjusting screws on the T-Bar are not intended to to adjust the height of the fence from the table. Their purpose is to adjust the fence perpendicularity to the table. The height adjustments are made from INSIDE the fence tube as I explained earlier.

Thanks Joseph. After I squared the front rail up, I put the other screws back where they were. It works great now, but I’ll look for those other screws so maybe I won’t forget next time.

If worse comes to worse you can always put some shims (a washer or something) between the tube and rail to elevate the tube just a wee bit. (or is that a skosh?)

-- Some problems are best solved with an optimistic approach. Optimism shines a light on alternatives that are otherwise not visible.
