Here's something I thought up while edge joining some boards. I needed some extra reach, since the Kreg face clamp didn't have enough.
I took a 2" square of oak, made a rounded 1/4" deep x about 3/8" diameter depression on one side in the centre to receive the "pin" part of the Kreg right-angle clamp. Voila! A larger face clamp. It's cheaper than springing $35 for the larger face clamp from Kreg. Besides, I got the right-angle clamp a freebie with the Pro kit.
Now, if only I can find a way to stop the block from falling off!
