Awesome!!! Great idea with the slots!! I may take you up on that file when I get caught up on other projects... I've been thinking of building one myself.

I like it!
If I may...You may want to add more filler next time to your TIG welds, as they look a bit too concaved, probably from you beveling the edged prior to welding. When the bead shrinks back like that it is thinner than the base material and creates a weak spot. When welding a joint like that, the bead should be as thick as the base material.

Thanks DTM, Those welds are in compression so didn't bother to put a big bead on them.
