Brad,
Havn't givin up yet!!! I just got back from a road trip and now I have to pack up and move out in the next few weeks. Once I get my endmill holder and am moved I am going to make a few of these blocks. I got a guy that need 2 blocks for his dully which I am going to probably use this design aswell. I just need to get the holder, move, and get the material!!!!
