Thank you very much, that means a lot from someone that is from a team that is in an area with a much larger population then little old Norwich, NY

That is very true, when I weld alum. tubing I cause put 2 tubes welded into a "T", let it cool, put it into a vice and rip the alum all around the weld before breaking the weld. It's because the areas around the welds became heat treated and became weaker.

I haven't seen any of my welds on a robot "shatter", but every year i have one cracked or fully broken weld (often my crappy welds). What is nice about epoxy is that it has some stretch to it.
