I have one ram now thats used for several things and it's long overdue a replacement.. So I scrounged some ram and a bit of cylinder, The cylinder is 50mm and the ram is probably 40mm. I got it about three years ago infact..
I asked at the place I got it about seals and they said 'make the pistons and bring them in and we will find some seals'. I was hoping for an old catalogue showing sizes of a common seal. Is there a website with seals and standard sizes, drawings of the required grooves is basically what I am after.. I might get some larger tube for a ram for a press..
I was wondering about making the press ram double action, retract as well as press. I couldn't see an easy way to incorporate a return spring.. any suggestion..
