Anything over 1.5 mm needs a lot of engineering if the bend is wide or the system will bend

Sean, I have plans for one, send me a pm with your email address and I'll send by return

Sean, email sent…

I attempted to use one of these to bend 2.2mm thick by 500mm wide yesterday and could not budge it. (It is rated for 1220 x 1.2mm sheet metal).

Ended up reducing the plate thickness along the bend lines with an angle grinder. Still took some effort with extended lever handles to bend plate.

Hi Sean, as has been said, 1/8" (3mm) much over 6" wide will take a fair bit of effort to bend in a hand sheet metal bender. You would need a moderate size machine like a press brake, the one in this advert below would only do 12" wide for 10g steel, approx. 1/8".

I was given the job of making a small bench hand folder at work some time ago now. The base plate is a piece of 200mm wide by 30mm thick flat bar, welded on top of a piece heavy channel and the top beam is a piece of 100 x 100mm x 10mm thick angle iron which was stiffened up and the folding part is 150 x 75 x 10mm thick angle iron with channel iron gussets, this will accept 1M wide sheet, but 2mm thick steel is its limit and that takes some grunt for that width, I could take a photo it if you like, but not until Tuesday next week. If you have a workshop hydraulic press, you could always get or make a "V" block and a forming tool.

Regards Nick.

P.S. here's a photo of my make-shift press I cobbled together to bend a couple of pieces of 6mm chequered plate.

Did you mean rolls rather than bending?
