Qiusseppe,
Sure. The pressing process is a cold process. nothing is hot. The copper is annealed and in this case 28 gauge thin.
I'm pushing it with 20 tons of force at my disposal..it moves. I cut the Plexiglas die with a jewelers saw. see pic 4-4 the Male part of the die is made slightly smaller on a belt sander. You can click on the thumbnails and they will get bigger. They can be made bigger still by using the magnifying glass toolbar bottom right. 150% makes them easier to see. These are not renderings..these are real pcs. Fold forming is using the way metal behaves and folding to rapidly create forms. It was developed by Charles Lewton Brain in the late 1980's. . I use the press in FF to create creases and as a vise. I also use at times a break a rolling mill and the usual hammers and anvil. I'll be very happy to post more pcs. Brad It's what I do.

Brad, Thanks for the demo. Die forming is a great and underused technique. I do not have a press and so I have to revert to using hammer and punch. I will post images later of the method I use.

I look at the press as a giant one blow hammer. We both celebrate the elasticity of the metal. I have a beer, you a fine wine. I'm looking forward to more images of your method. Keeping my pitch warm. I have to anneal and roll some material this afternoon. Getting ready. Brad

thanks brad, I would like to see more of the folding under the press .... as for the plexiglass, I mistakenly thought that you had deformed the plastic to make a female die .... I now realise that you cut a hole right through.

What is giving you the lines in the square bowl ?

The lines the small platter are T-folds. The heavy lines in the round copper earrings are the same technique, It's easier to see them. The platter required that I first create the pattern of T-folds before folding the platter. T fold is a basic named fold. The fold is hammered at 90% to the sheet of metal. In this case the press is used as a vice to hold the metal. Tapered T-folds can result if the metal slips. These first folds were done with a break. This pc is 22 gauge. I feel a demo coming on..later on in the week. Thanks for your interest. Brad

I've used a Bonnydoon They are nice... I made my first press about 30 years ago. It served me well. This press came from Harbor Freight.. not very expensive..Just a few modifications to make it do what I need..This way I have funds for metal and fixtures for the press.. Brad

Janice.
Fold forming and my smashing contraption are two of my passions... Love to see your folded pcs.. Brad
