[TheForge] Sheet metal bender

[dan at irontreeworks.com]

Thanks all.  Peter or Phoebe ....That is the simple bender that I was looking
for.  Thanks...I have a giant bending fork....why didn't I think of that....I
was hung up on looking at benders from Harbour Freight.

Mike, I'll likely weld it instead of a lock seam, though I would like to know
what that is...picture?

I can weld the stainless with my MIG.  Done that before.

I like the slip roller....I think I could make one, but I don't need one for any
other project......so

Anyone got a slip roller in the Minneapolis area that I could use for a few
hours?  I'll write the GOM list for this too

Dan
