OK this is related since I am working on my 6x48 edge sander. I started this last weekend to do some refurb work on an old sander (made 1988) purchased through a fellow SMCer. I disassembled in to clean up and do some painting along with have some missing parts fabricated. Anyways, there is a bolt in the belt tracking unit that was broken (hidden), I could have even busted it when taking apart. I have only begun to reassemble, so I am not sure how much it would effect the task or not. It is a left handed threaded bolt-thingy that has the last 1/2 or so machined down (I'd say almost just grinded down) with a middle portion grinded even more to accept a set screw. Well, it broke int he thiniest section. I had some JB weld laying around and thought I would give it a try. My question is for folks who have used this stuff, how well does it work. The ads say it will be just like new essentially, but can I actually expect that it will hold? My plans are to let it sit for a few days to really harden before reassembly.
If it doesn't, I will have to find the right sized reverse thread bolt and then have it milled to match the existing part. I doubt I could locate a raplacment, not your standard brand name (Mao-Shan is the manufacturer and it is labeled through Wood-tek.
I was just curious about how well JB Weld works.
