Thanks for the two replies. After a day of removing stuff and crawling around inderneath, and yep, looking at all kinds web based info sites, I am further ahead but still in a pickle. The supporting panels that make up the underside of the 'box' have rusted badly in one area/seam/corner. The supporting framework for the stairs themselves are bolted to that.


The problem now,is that behind that panel is wood. Welding is going to heat that wood in a hurry. I am thinking that if I spray in a fire retardent and then soak/spray it, prior to welding.
If the 'box' was easily released, I'd do that in a flash but it looks like a huge mess to do that.
Thoughts?
