Thanks Terry and Tree Hugger! I really appreciate you both taking the time to help me out! Yes, I believe it is the allen head or wrench that is stripped. I will go buy a new one tomorrow. I do currently use mine for all thicknesses of boards not just the 3/4", that is just what is happens to be stuck at - at the moment. It's frustrating to be gaining momentum and then be stopped in the middle of a project from a tool malfunction. I'm sure you can understand! Again, thank you so much for your advice. Tree Hugger - I will have to look into the never seize you mentioned!
I would consider myself a bit of building newbie - but making progress! I sure love it! Here's what I'm working on - the rest will have to wait until I get my new drill bit and collar.
