[TheForge] toys how many?

[Jerry Frost]

I don't have a specific design in mind or a URL on tap. So far it's been a 
back burner project awaiting a real shop. In fact I'd planned on having 
rolls before I decided I'd like a press too.

The concept is pretty simple and there are a number of approaches. Basically 
press rolls generally have a static bottom (anvil?) roller and a movable top 
(hammer?) roller. Some drive top and bottom, some only drive the bottom.

When I start noodling around with the thing I'll start with just the bottom 
roll driven to simplify things. If it isn't enough I'll try scrounging or 
designing a mechanism to match speed on both rollers.

If you picture a large rigid smithin magician with rollers instead of dies 
you'll have my initial idea. Please bear with me I'm brainstorming from here 
on in

Instead of a single flat slide/guide like a magician there'll be two, one on 
each side. The lower half will be the guides (female) half. They'll be 
doubled, probably 1/2" x 8" x ?" high, seperated on the edges by 1/2" x 1" 
rec. bar welded in with a little clearance, I like pasteboard about phone 
book cover weight. The clearance will allow the upper slides room to move.

The guides will be drilled for shaft bearings to carry the lower roller. The 
buides will have to be welded to a really solid base plate and either tall 
enough to clear the roller or the base plate will need to be open to clear 
the roller. The lower shaft will be connected to an appropriate reversable 
hydraulic motor via suitable gear reduction to yield sufficient torque at a 
controllable/comfortable speed.

The bottom half will need a positive way to mount it in the press with 
consideration for the long stock passing back and forth through the roller. 
Placing the press will be important as you don't want to have to make a hole 
in the wall you know. <grin>

The upper (so far) undriven/slave roller gets mounted to a "fork" made of 
1/2" x 6" x ?" high that matches (male) the (female) guides on the bottom 
half. See the resemblance to a smithin magician? We can call it a "Rollin 
Magician" if this idea works eh?

Anyway, the male halves of the slide will have to be slotted to clear the 
drive shaft and connected at the top by a robust drive plate. The roller 
shaft on top won't have a drive connection (so far) but it probably wouldn't 
hurt to leave it long enough in the prototype.

Shafts and bearings will have to be hell for stout of course. Keeping things 
aligned will be critical, etc. etc.

Like I say it's not a technically difficult device but it will demand a 
professional level of precision.
