Partly because I’m not “trained” in sheetmetal I’ve just done what I feel led to do. So there were several things I tried that I’ve not seen my hero’s do, but I was kinda stuck, so what the hey? There is a LOT of discussion on the pro sheetmetal forums about dealing with the resultant distortion when you tip and edge and especially when you run a bead in the middle of a panel. When you think about it, you’re effectively shrinking it. So most say you need to use the EW to prestretch where you are going to put the bead.
I just went for it because I tried it on scraps and couldn’t see the difference. But I also noticed the bead doesn’t leave the surface flat. So I remembered the blade I made for forming with the arbor press. I used it on the edges of the beads on both sides and that seemed to take the “oil can” out of the surface. Did it on all three beads and it really helped. The real help was the lowly hockey puck, what a boon! Glad I bought three as I can see I’m going to be using these things for all kinds of stuff! I put one on the arbor press, one on the old Manley screw press and one on the bench. I wish I would have had them when I did this copper forming. I just had a scrap of rubber. The blade on the arbor press is handy because it’s easy to change orientation to get at different parts. I’m going to have to make one for the Manley. I’ve got one of those 2” cheap tailstock chucks coming that I’m going to adapt to the Manley so I can put different size dapping dies in it. I used an 8mm dapping die to make the ends of the beads distinct.
