[TheForge] Sheet metal roller qestion

[Walter L. Mullett]

Dave brown can probably answer these:

I picked up a clean, antique sheet metal roller today.  It's got 3 - 30"
rollers with two geared together and one of those has a crank.  Small
adjustment on the top roller for metal thickness.  Each roller is about
1-1/2" and the outfeed roller is screw adjustable from an almost parallel
position with the bottom roller to almost parallel with the upper roller.
The name on it is "ULSTER".

The outfeed and bottom roller both have about 4 grooves near one end with
each being a little different in size.  I assume that would be for a hem
turned out?

What kind of diameter could I get with this?

I think I stole it at $7 but my better deal was a Lincoln 225 AC welder with
50# of rod, 2 helmets and a cart for $30.   HUGE SMILE
