Does anyone know of a tool with which I can curl over the
edge of a sheet of sheet metal to make a lip. I think sheet
metal worker may use some thing. I want to know what it is
called and who carries it.
I know the tool you’re looking for, however, I don’t know it’s
name or where to get it.You might ask at a local sheet metal or
heating & cooling shop.
Assuming you want to used it on relatively light gauge material,
you can make your own. Use a piece of steel about twice as thick
(or thicker) & 2 times wide as thick than the lip to be formed
(ex. lip width 1/8", metal, 1/4" thick, 1/2"wide). The length can
be any convenient length to work with, 4-6". Draw a line down
the center on the 1/4 side. Mark a spot on this line about 1/4"
from 1 end. Draw a line perpendicular and across the center line
at this point. Drill an 1/8" diameter through the piece at the
intersection of the 2 lines. For a really clean hole, ream it or
polish the inside. Cut the end from the bar at the perpendicular
line. The saw cut will go through the diameter of the hole.
Remove any burrs & polish the end of the tool. You now have a 1/2
round punch for rolling an 1/8" lip on the edge of sheetmetal.
Steel keystock from the hardware store can be used to make it.
It comes in various sizes for under $2.00 per 12" length.
