Does anyone have a fix to their muff pot bases cracking on the corners of the bends? I've gone through 4 of these now on 3 different sleds. Have to be able to tighten the base down real well or it comes loose over time. Was thinking of making a thicker base (tig) and riveting back on the hold downs. Anyone else have a better solution? Yes I know I can send it back for warranty, but I want to NOT have to worry about it anymore instead of a new one that will just crack again.
