As I mentioned in my last post, I was going to do a large patch, here's how it went.
I had made templates from wood and wood screws, to have something to check the
shape of the sheet against while I was rolling it.
Back at home I measured the new sheet centered and level and fastened it with four
sheet metal screws in lieu of clecos.
Then a lot of shrinking in the deep throat schrinker-stretcher. When the shape looked
okay, I made a
3/
4" flange using a tipping die in the bead roller, then
shrinked the flange to get back to the right shape.
Having watched a lot of Fitzees Fabrications videos on youtube, I had long thought about
trying his cut-n-butt method. I did now, and it worked a charm. I cut some, then made a tack,
cut some more, made a tack and so on.
The body was extended downwards as far as I had made the new wheel arches three years
ago. Turned out it was two inches, not three as I mentioned earlier.
