I thought that this has been discussed here before but I tried a search on the forum for this info to no avail, so I am asking. Can anyone with experience give me advice about repairing hot sticks? I have two that are damaged that should be perfect to use to make one good one - one with a broken top section (outside tube)and one with a broken bottom section (inside tube). Can they be taken apart, exchanged, and put back together? If so, how is that done?
