I'm testing one of these jigs...
Ed was good enough to send me one to test and report after I try it. Wish I'd had it soon enough to use on the last 3 TDS , no fault of Ed's on that tho.
I'm impressed with it so far, all I've done is a mockup 2" wide with an awood block and a pair of maple 1x2s .
Here is data so far:
It came in closer than any jig I've used to date.
The drill holes were all the right sizes.
Ed has his own (I assume) insert system that used a 3/8" hole in limb that fits over a part of insert that comes out of riser and is 3/8" with a rounded beveled end on it so the bolt is rock solid.
Getting some pics in order as I have time.....
