This technique works so good that I was wondering if others were doing it. JB Weld tends to go on kind of clumpy (or in small globs) rather than making a nice smooth fillet sometimes. After apply it to the joint, if you want a really nice looking fillet take a heat gun or hair dryer and warm it up. It will then flow nicely and the result looks much more professional. If possible you can pick the piece up and turn it a few times while heating and get it to flow exactly the way you want it to. This works with regular epoxy too.
