We used to have a sponsor weld our frame, and he always had trouble with the butt-welds. After we added gussets... even the kids could do it.

or in most cases you could take those same little gussets and pop rivit them in place instead of welding. Having spent 5 hours under the mask last night, this is now our course of action. I mean i thought the point was to make each joint so you could see through it :-)
