I bought a used saw and someone made their own for it with a piece of 5/8" box tube. I will try to remember to post a picture when I get home from work. essentially it has a cut on one end, capped and it's threaded with a wing nut to tighten it. the arrow end has a hole drilled though it with the edges sanded smooth, the arrow goes into the tube and rests against the back wall. It's always worked well for me and I've cut several hundred arrows with it since I've owned it.
