T Style Radius Insert for Old Version of Fretboard Radius Jig

First of all, let me say that after owning this jig, I would never consider radiusing a fretboard again without it! Not only does it save A LOT OF TIME, but it saves my arm. I typically use very hard woods for my fretboards and shaping them the old fashioned way, with sandpaper and a radius block, was killing my arm.
I only have two complaints: 1) the jig is so tall that I have a hard time finding a router bit long enough to reach the fretboard, let alone long enough to actually cut into it without just barely clamping the bit into the router chuck (which is dangerous and scary). I ended up having to shave an 1/8" or so off of the bottom of the base to allow the fretboard to be raised up closer to the router. It's not a perfect solution but it's better than nothing. 2) the screws that hold the radius pieces to the side rails of the jig cause the side rails to flex out when you get them tight enough to hold the radius securely in place. Sometimes it even causes the radius pieces to lift up slightly. Instead of using friction from the screws to hold it all together, it would have been better if the screws went all the way through and actually clamped it together. At least having screw inserts in the radius pieces would be better.
