As you know Im working on chute body a lot like the one you built Glen.
I have it all welded up and starting to suface grind the welds some,I do ok at aluminumwleding not best by real long shot.
I have almost zero warpage,lots of tacks. Do have some buildup spots and some blow thru. Do you just grind bottom side some and leave or do some weldover(underside) and surface grind them. I would like to say botom is all nice and smooth and pretty,but I'm not running for office and not taking liar class'. Any pics of process on any of your might be cool.
I was thinking a Roo Man's fabricating video series would be cool and once word got out site might pic up some activity. Yea probably huge pain. Plus no reason to give away hard learned trade secrets,right.
