Default Need some help/info

Hey guys- I need to turn a flange on a 24 ga stainless steel tube that is aprox. 1 1/4" dia. I remeber seeing somewhere a rotary machine called something like a "pepperbox" machine, or something like that. it looked like a minature buring machine. the dies appeared to be really small, but it was a drawing, not a photo. it was in a really old book or PDF but I can't seem to find it anywhere. Has anyone ever heard of this before? I'm looking for information on the Dia. of the dies, and what the centerline between the two are. I've tried using google, but didn't really get any results. Thanks guys-

Hi jw,
Have you ever installed a blow pipe system with angle rings or Kirk & blum rings? When you
put a loose ring on so you can alien it you use a van-stone connection. The same
technique can be used to turn a flange on just about any pipe. Get something,wood,metal,
pipe that fits tight around the outside of your tubing, make something if you have to,and slide it down so the length of your flange sticks out. Use a small ball-peen and tap your flange out[I'm assuming it's an outside flange].
With a little practice you can walk it right around. Google van-stone connection.

Thanks John- that's similar to how i did the last one. I used a small hammer and tipped the tube edge on a block of wood, and turned the flange outward. it turned out pretty good. This is actually just a stem piece of an inlet screen I'm working on. The tube will slip through an 1 1/4" hole in the screen body, and then the flange gets spot welded to secure everything. I just thought I would get fancy...Still trying to find that book though. Thanks for the help.

Check out Machine Tools for Sheet Metal Work (Pexto Centennial Edition) sec.N
There's a pepper box machine that will turn an 1/8". Bottom roll is 1" Dia.In the
library.
