One guy said it may have been used with a slider? Wasn’t a slider in stuff I bought.
Oddly enough the angled piece, or gusset, doesn’t appear to be welded to the main fence, but both pieces are welded to the angle iron slide. There are no visible fasteners holding it togethe. Cam lock is missino.

It seems the Scmi offerings used an offset fence, guessing that’s what you got as it’s definitely a Biesemeyer fence.

Awesome picture, that was some impressive engineering to figure out how to keep the t-square functionality but get flush to the blade. Thanks for finding the picture/video.Good find. Here is a screen grab from a restoration video.
Thanks. I was glad to find out what it was. As I restore the two saws I’ll put the Paralok on one and the oddball Biesemeyer on the other. It should work as well as any T square fence I suppose, it just looks a little odd. The Paralok is actually pretty cool.Awesome picture, that was some impressive engineering to figure out how to keep the t-square functionality but get flush to the blade.

That odd Biesemeyer would make me crazy. No way to use the right side of the fence.Thanks. I was glad to find out what it was.

Converted it back to a standard Biesemeyer Commercial. I’ll strip and repaint before I reface it.That is it! So is it a Biesemeyer? That even looks like the same sacrificial piece on the fence.
Mystery solved. I watched the video and the guy says it’s a Biesemeyer. Thanks!

IMy dilemma is that the rails and tube are a full seven feet long. That would take up a huge amount of room in my shop, plus I seldom cut full size sheet goods. Cutting those rails would be a shame but I’ll have to make up my mind soon.
