Compound curves with an arbor press - new?
Compound curves with an arbor press - new?
Saw in the current Hot Rodding magazine, they have an article on a few guys who have gone to using wood or metal forms and little sandbags in an arbor press to form curves in car/motorcycle sheet metal, rather than hammering it.
The article said that the process was "so new that there was not any recognized name for it", though I bet a bunch of people have found it in the past already--but anyway.
I am just getting into metalworking (haven't ordered any tools yet really) and wanted a way to do curve shaping, but didn't have the room for hammering, english wheels or planishing hammers. Apparently you don't really need that stuff, if your parts are small enough to fit inside your arbor press.

Well how about a couple photos? It's not really necessary to read the dang articles to get the idea, though it does talk a bit about the methods they use.

The first photo is a guy who makes steel curved rams and pushes into a sandbag set inside a piece of pipe. The second photo is another guy who makes oak rams and pushes into a piece of hard urethane.

If the article is available by link (from the original source), that is acceptable.

Re: Compound curves with an arbor press - new?
I know this OP might be a little old but i just finished my shop press and i have used it to form some 1 1/2" steel channel into some half circles for a street rod project. Just kept moving the metal and had the bed plates about 3" apart and the channel came right around...Bob

This sounds very intriguing, please post pictures of your press setup and formed part from channel. Thanks, Steve
Just because you don’t believe it - doesn’t mean it’s not so.

I'm a friend of Bob Haverstock, he originally came up with the idea to allow a developmentally challenged young man help around the shop. In this way of shaping metal the tooling and operation are rather simple and inexpensive. He has published a dvd and can be found online. tt

Manual/quiet/slow planishing hammer technique?
Isn't that what Lazze is doing in the main video?

Is there some benefit I'm not seeing?

It's not hard you could do the same by using a hammer and stump, it is repeatable, controllable, affordable,takes up very little space, just one way of many to shape metal.

I've heard that Bob Haverstock has a kit for sale but have not been able to find it on the web. Anybody know how to get it?
