Roller Benders

[DaveH]

I started this Roller Bender in 1998. The design is from the book 'The Model Engineers Workshop Manual' by Geo.H. Thomas.
I changed the design slightly (as I always seem to do ) just to make it easier and quicker for me to make. I certainly could not improve the design.
   
As you can see the top roller comes off so I can get the rings.
   

I had to make some copper and brass rings ranging from 1.5" to 3" diameter. The material brass and copper was approx. 1/2" wide and up to 1/8" thick.

This is a copper ring made.

I made hundreds of these rings and the material always came with the order, he tended to be very possessive about the material which gave me very little room for error.
I'm not too sure where the rings were used, I do know that they were Silver Soldered or brazed.
He never told me where or how they were used and I didn't ask.

All the bearings are phosphor bronze

Nice job Dave!

I like the idea of the smaller control roller to help carry the radius closer to the edge of the part. I've used rollers before where the first inch on the part was pretty much flat. Nice attention to detail as well. It looks like you made pretty much everything but the socket head cap screws.

That purple paint job is pretty snazzy as well!

Thanks Tom,
Thanks John,

No idea why I painted it the colour I did - must have been a left over from my hippy days

Dave,

Nice! Add some pins stripes to that thing and it would look even sexier.

Very well made and nice pictures. Thanks for posting them.

Very nice Dave, slightly more refined than mine. Mine leaves about 2 inches flat at the ends but will roll 1/2 inch plate. Here its bending 5/16 plate 12 inches wide.

Bluddy marvelous Dave.

You've been holding out on us again....

What other masterpieces have you made that you haven't told us about?

[PixMan]

Beautiful work Dave!

f350ca, yours is interesting, I imagine that rolling 1/2" steel needs lots of power. How is that big one driven? Why does it leave flats at each end? I would think that most applications would require a full radius.

Wow Dave!

That's amazing! I,m with Willie what other treasurers have you been keeping from us?
