Re: Bending mild steel strip
Hi Peter: Assumption, all the same size? And you have a vise? Are the bends in the same direction? Or opposite? Even a propane torch can help. On the 30 deg bend, a larger radius would help. Cut a

Apologies as this isn¡¯t Unimat (or even lathe) related - I¡¯d appreciate some advice from those who will know. I have to make three identical ¡®legs¡¯ to support a metal shallow bowl water

Re: Machining 1018 Solid Steel Bar

Re: Machining 1018 Solid Steel Bar

Re: Machining 1018 Solid Steel Bar
You didn't specify the length of the part, but it sounds short and stubby so you should be able to hold in reversed jaws. Note:? Jaws must be reinstalled in the correct order in a scroll type
