Hi Folks,
I would like to add a pulling air spring (not a pushing style) to my bench CNC mill. The head is too heavy and sometimes falls and I would like to provide an assisting lifting force. I am thinking I would put a couple of pulleys at the top, a cable from the head over the top of the mill vertical and down the back to attach to an air spring. However, I have not found a source for a long (~20") stroke pulling air spring. Any suggestions for a source would be useful!? I suppose I could put two in series to achieve a longer distance, but one would be a nicer design. The head weights in at about 275-300# so perhaps two in parallel would be better balance and at around 130# each.
Thanks,
Dave L.
