rethreading bolt holes
I need some help from you guys. I was recently given some risers that were used and were crossthreaded. Luckily they were free, but they are useless to me at this point unless I can rethread them.
Is this possible or should I trash them and find different ones?

RE: rethreading bolt holes
I have rethreaded blind holes and used heli-coil inserts to get back the original size thread. On a riser I would not rethread a hole. The inserts would be fine and give original strength or better. Rethreading a blind hole usually is not going to give enough good thread and will be easy to cross up again. A little no hands is fine when you want to do it. No fun when you don't. Mike

RE: rethreading bolt holes
How much length-wise of the threads was screwed up? Short distance, I'd try rethreading them. But that'd have to be less than 1/4 the length of the bolt going into them. Or counterbore the holes about 3/8" deep, rethread the remaining part to original thread size, screw in some studs, TIG them in the counterbored section, and then use nuts underneath the tree.
