I picked up these three bead rollers today! Two Niagaras and one Pexto. The niagaras have shallow throat depths, one has what appear to be flang making dies while the other makes a very tight radius bead. The Pexto does not have any dies attached.
nice! my school has alot of those under the benches, bead rollers, crimers, swedgers etc.
were they pricey?
http://www.roperwhitney.com/ has them.Does anyone know where I can source some dies for the pexto?
All three look to have dies to me. The one with what looks like gears is for making the "male" end of round ducting. after the flat sheet is run though and then the piece rolled and locked together (another forming machine) The "knurled edge has shrunk and fits inside the unformed end of another duct.
I have 5 or 6 of these; cool tools!
