Previously there was mention of Jet blade holders. I spent the $20 for a set of three just to see what they were. I received them and modified one to work. First of all there is a through hole, one of which has to be plugged. The holes are large enugh to drive a truck through. The hole that was no plugged needed to be plugged and re-drilled which I did with a #52 drill. This is still a bit large but will accept some of the large blades. Then a flat was milled on the opposite side of the hole for the clamping screw to seat on. Don't think I will bother with the other two. Easier and cheaper to just purchase clamps. But, it was fun.
