[TheForge] Yellin question

[Steve Smith]

Thanks Chris. I have been staring at this problem for awhile, then found 
the Yellin piece. I thought about putting a rolled edge on the sheet 
side, but I suspect decorating the roll with chisel cuts would'nt work. 
I could use a file.

The best I've come up with so far is to half roll an edge over a second 
piece of sheet. This would let me do double layer piercing, and it seems 
like the rolled edge would stand up to some chiseling, given support 
from underneath.

Now I need to try some of this out.
