Another concern I had was drilling new holes close to the existing ones after filling them with JB weld or epoxy. If my bit catches the JB weld, will it prevent nice straight drilling through the wood, or does the weld and epoxy cut easier than the wood. I have often found it difficult to keep the drill straight when two different materials are being drilled at the same time.

I ask this because I will have to enlarge the original holes in order to remove the blind nuts. This won't leave much, if any, space between the two sets of holes. I am afraid they may overlap, thus causing redrilling problems due to different materials.
