i ve working with my press now since 3 years, and i always had a struggle to feed the press with the cassttes. the horizontal opening is only 195cm, when i welded it i was hoping its enough, but my cassettes are 200cm. the vertical opening is 40cm. the horizontal C-beams are welded properly, the horizontal I-beams are screwed to them.
so, my idea to widen the press opening is to move the two racks to the left and right. i could do this 5cm each side and won t loose the support of the outer C-beams. to gain more space (would be more comfortable) i d like to move them 15cm each. but i m not sure if one C-beams each side is enough support, it s not that i m doubting the stability of my welding ... but could it effect the deflection? its now 1mm per bar...
i also would like to make the vertical gap adjustable, maybe with car-jacks(but where to place them), or even pneumatic zylidners..but this would be a very expensive solution.

the frame with the threaded rod is placed in the middle of the press to avoid deflection. it s always enoying demountin it to load or deload the press with cassettes...
