Here's some more squishing ideas:

Bonny Doon has been going awhile .... sometimes it takes awhile to develop a really functional mechanical gizmo....:rolleyes:

Looks great, Will. I was happily surprised to see PatMan's kit set up with your smaller press. We had a great conversation about what an arbor press can do. Pretty deceptive. If you have or find a cheap arbor press, it's a no brainer. The throat depth is the primary factor determining the size of work can be accommodated.

I've been working with this process for a while now and like it a lot. For certain shapes, it's fantastic. It is slower than other powered methods but it is silent, totally self-contained and very kind to sore body parts. It isn't going to do everything, but it will do a lot while not creating or leaving a single tooth mark that needs to be filed or sanded off like the Lancaster-type shrinkers/stretchers. Very cool...

I've also been wondering how feasible it would be to convert one with an electric motor- especially after seeing Will's nicer shrinker and stretcher that he built- to cycle the ram. Pretty sure someone else will get to it before I ever do.....

Your very limited by the close distance between the vertical members of that kit. I think you’d have a really hard time making your money back with that, I just can’t see it as being all that useful. ~ John Buchtenkirch

Looks to me like it would be very handy for motorcycle tins.

use a plain arbor press for the bike fenders, tank parts to weld, etc and save a ton of money over the Bonny Doon. I think there's any number of quality machines available through AMS members/companies here that would be a much, much better investment...

I got into the arbor press stuff specifically to do bike parts. It's really easy to be too aggressive with it. A 2 or 3 ton press will often have a throat of 10"-12" and usually only cost up to $300 or lots cheaper if you look around. It doesn't take much effort to move the metal- the only reason to buy a bigger tonnage press is for the increase in throat depth. A little 1/2 ton press will easily shape alloy or crs panel. That's what I mean by how deceptive this process is.

Before I bought the Bonny Doon, I would get a regular shop press with much greater dimensional capacity (and maybe air over hydraulic and more... $1k-$2k will buy a LOT of used shop press) and make some tooling for it. Some are doing it with a regular shop press instead of an arbor press.

Another one of the lingering projects here- I've been watching for both another cheap arbor press (to cut up) and a shop press frame. i want to be able to replace the hydraulic Jack with an arbor press ram and actuating lever as a better approach than working the Jack. Turning the ram and lever sideways would probably make it even easier to use a foot pedal to run the ram and free up you hands.

I hope Patman will post the reason he went to this trouble to provide this particular offering. It's not about the money.

Will, i think that comment was directed at the Bonny Doon kit. It costs as much as one of Peter's HandBuilt English Wheels!!...... PatMan's kit isn't that expensive, is it?
