Tonopah Bill Posted August 5, 2012 Share Posted August 5, 2012 I was wondering if anyone in the Phoenix area knows where I can find an arching or Re-arching anvil. The suspension shops that might have one for sale dont seam to want to sell them to locals... I guess their afraid i'll open my own shop.

bigfootnampa Posted August 6, 2012 Share Posted August 6, 2012 I've never heard of such an anvil... till now. You can cold arc leaf spring material up to 1/2" thick and as tight as 16" diameter on a standard anvil though. The usual technique is to hammer on the inside of the arc with a rounding hammer over the hardy hole at evenly spaced intervals until the desired curve is achieved. Hammering over the step area will also work... a bit faster but not quite as controlled. I would guess that most commercial shops would form springs in some sort of press rather than on an anvil... the shops that won't sell you one might not know what you are talking about!

David Gaddis Posted August 6, 2012 Share Posted August 6, 2012 Most spring shops I ever had any dealing with rolled the metal through a three-wheel device that was powered. As one wheel closed into the specified position the new radius was formed. Variable radius were formed by computer controlling the third wheel roller. Sometime you see people bending tubing the same way but with specific dies to elimate tubing collapse. Quote Link to comment Share on other sites More sharing options...
David Einhorn Posted August 6, 2012 Share Posted August 6, 2012 Do you mean an "eye roller" ? http://www.vicroc.com/english/hydraulic/ef800e.htm Quote Link to comment Share on other sites More sharing options...
fluidsteel Posted August 6, 2012 Share Posted August 6, 2012 With all my googlefu I was only able to find reference to one anvil made for arching auto springs.(and that was by a bunch of machinists....) This picture from the 1876 Centennial Expo has a 450# Fisher with what looks like dovetails cut into it. What is that Fisher made for? Is there even such a thing as a re-arching anvil?

ThomasPowers Posted August 6, 2012 Share Posted August 6, 2012 What are you wanting to do with it? Is is something that an old wagon tyre roller might work on or is it something a bulldozer press would be better for. If you give us an idea of intended use we might make better suggestions on what to use and how to find/make it. Quote Link to comment Share on other sites More sharing options...
Big Lake Forge Posted August 6, 2012 Share Posted August 6, 2012 Look at that 1400 pounder on top. man that would b a nice anvil to have. Quote Link to comment Share on other sites More sharing options...
bigfootnampa Posted August 7, 2012 Share Posted August 7, 2012 I think David was thinking more of a heavy powered version of a ring roller. That would make sense. For someone not really in the business though... such a machine would be extraordinarily exorbitant! If you WERE in the business you'd need an eye roller too!

eric sprado Posted August 8, 2012 Share Posted August 8, 2012 Many springs are arched COLD. Terrible on the joints. Shop here in Eugene still does them that way... Quote Link to comment Share on other sites More sharing options...

Tonopah Bill Posted August 8, 2012 Author Share Posted August 8, 2012 I want to rearch the springs on my truck my sons truck and a couple of people I know want me to do theirs also. I can do it other ways, but nothing beats an anvil with an 8 to 10 lbs hammer.. Quote Link to comment Share on other sites More sharing options...
