Yes, it is shop-made from some 8020 aluminum extrusion and angle scraps. I emulated a commercial fence I had seen (pic attached). The clamp handle is from a table saw I scrapped out. Very simple, yet seems to work very well.
I thought exmaxima did an awesome job making the fence. I've already ran a few pieces through the saw and they came out great. I also looked up the serial number and the saw came up as a 1949 model. Awesome. If these old tools could only talk!
