Hi I'm trying to fabricate some patch sheet metal for my classic merc. I will have to produce some curves and I thought the easiest way to do it is to use tuck forks and to try to heat shrink the tucks. My question is what is the easiest way to fabricate tucking forks. I thought that the easiest way to do it is to buy two sets of pry bar and to weld them together. Do I have to do any modification? Thanks for all the help.
