Hey Dave,

Nice job and again I really like the filler tube idea a lot (I would have more ER70 in mine). I went to youtube and you were actually #1 there with just "TIG welding cart" I think it was.

Cutting the rubber tubing to fill the larger hole is a good idea too.

Nice work, keep us posted on the future projects.
