    That is the smallest boring bar that I have and it just barely fits in the T(.360") letter drill hole. The compound on the small lathes sucks as well. It is a 7 degree taper 1 1/2" long, the radius is 1/4" diameter. I have no bench mark to compare the performance just hoping for the best...

    Pickup the 48"x 48"x 6" piece of 1 pound virgin expanded bead polystyrene today that hopefully will become the wing cores. The cost was $53.00. The factory is about an hour from my home. The last time I bought foam from there was in 2003 when building a Hurley Extra 300.
