I've been wanting to make a scroll bender for a while now, but I've always been stumped on how to make the scroll properly.... Found an old blacksmith trick for figuring out a "Perfect Scroll" and took that info into Corel & it worked. I don't know if anything like this has been posted before so here's another one if so.
Anyway, I don't have a lot of time these days to get to drawing the center & breaking the scroll into sections, so I thought I'd throw this out there to see what the collective can do with it!
Happy Scrolling!

Re: A perfect scroll
Similar to what your after using pin's, something I started long ago and lost track of it.

Re: A perfect scroll
As far as the layout of the spiral goes, it's just 3 half circles each with diameters half that of the previous (mine is 6", 3", and 1.5" diameters for example)

Re: A perfect scroll
I strayed across this the other day. There are two common types - Archimedean spirals and Logarithmic spirals. There was a site that would generate a DXF for either type, but I can't find it now.

Re: A perfect scroll
Played around with this a little more today... This what I came up with... Thinking to drill & pin each piece to a 3/4" thick plate that my vise is attached to. Any ideas & improvements welcomed!

Re: A perfect scroll
You may think about a way to rotate the jig instead of the material. Never know what you might need to put a scroll on, and having 15 feet of 1/8" by 1" swinging 360 degrees around the shop would surely prove to be unwieldy.Oldsarge wrote:Played around with this a little more today...

Re: A perfect scroll
Did you see the scroll attachment on this bender that you can make? Check it out in the video starting at about 8 1/2 min in. The whole thing is an Instructable.

Actually for some time now I've been thinking about fabricating a ratcheting head that I can mount various bending jigs to that I could ratchet around as I bend instead of moving the material... Now that I recently picked up a mill that I'm trying to make heads or tails of I might try to do something along those lines!
