If you already have a press, then it will not be bad to make a special attachment for bending metal. An additional fixture can be made with your own hands according to the size of your machine.
For crafts, it was necessary: a sheet of metal 12 mm (base), a pair of pieces of the 25th corner and a segment of the hundredth, as well as a rod from a car shock absorber, two bushings and four valve springs. The exact appearance of the product can be seen in the video and taking into account the nuances of your press to make something similar.
This craft is very functional, thanks to the use of a hydraulic jack it can even cope with stainless steel.
