At the moment I'm still waiting on getting my bus. I'm thinking in different directions, thinking of rivetting patches over the windows I don't need. I'm also considering welding patches. I know Harbor Freight has a $80 welding gizmo. Only problem - I have no idea how to weld.
There's this welder http://www.harborfreight.com/70-amp-ac- ... 68888.html
I don't know how well that would weld 20ga sheet steel over a bus window aperture.
This is largely why I'm thinking of rivetting because rivetting is something much more familiar to me.
I *think* this welder just causes the welding rod to heat and melt where it contacts with the steel. I'm assuming that one has to swipe the thing at a constant rate and that I'd likely go through several welding "sticks" per window?
Maybe I'd better just stick to riveting or even torx screws?
