Looks like a Biesemeyer clone. I put a Jet Xacta fence (Biesemeyer clone) on my Unisaw. I just had the fence and no rails or tube.
I went to a steel supplier and bought a 3/16" wall 2" x 3" tube, and some angle iron. I wanted 1/8" wall, but they didn't have it. The orig. is more like 1/16" wall.
The tube works great. The fence doesn't raise up as much, when using stock feeder or feather boards to hold the stock down.
Extra weight can only help things also. Not to mention I use it as an anvil at times!
I think the steel ran me about $65.

I did *exactly* the same thing. 1/8 wall 2x3 and 3/16 3" even-angle. 5ft of each, plus 5ft of 3/4 aluminum stock (for the setup spacing) was under $60.00 from the local metal yard.

I got a fence from http://vsctools.com/ and an aluminum extrusion from 80/20 inc. I am pretty happy with the setup for under $300 total.

-edit-
and I'm already looking to upgrade to a Unisaw.

I used the 3/4 aluminum to keep the space between the tube and angle iron at precisely 3/4" while I clamped the steel and drilled holes. I later used it to align my fence with the 3/4 miter grooves. It's just spare, square stock. I'll re-use it if I build another fence.


I got my Steel from Shapiro Steel in North St. Louis. Nice indoor yard. They sell online, but the shipping is probably kinda high.

I'm probably going to start over and build another if I get the Unisaw

Ok....so I need to find someplace cheaper to get steel......I need to do the same thing for a unisaw my brother in law has.......but the steel place here wants over 200 bucks for the rails and tube.....

I forgot to get a piece for the backside of the saw, but I left the old tube-rail in place. Either way prices are nowhere near $200 here.

I have thought about upgrading the rail and getting the fence linked above from very super cool tools. On the other hand I have thought about going the cheaper route of giving it a tune up and mod it a bit, and adding a one piece rail in the front that is a bit longer. I keep going back and forth about it. I guess you could say I am on the fence....

I really like the VSC fence, but I'm a tad disappointed in the quality of the extrusion. I bought it right from 80/20 (not VSC) and it has a bit more deflection than I thought. Of course it takes a fair amount of pressure to actually deflect the aluminum, so I expect that it will be fine in practical use.

Still way better that the unisaw-clone pipe that came with my Asian Jet. I tried several times to tune and adjust the pipe-fence, but it's never improved. It's always been a PITA.
