Pneumatics help

**psychostorm** · 27th August 2012, 12:57

I've recently bought a Heavyweight chassis & am in the process of (slowly) completing it.

I've also got a regulator on the way and a ram here.

Bad news is though, that the ram 360*100. As a consequence, is having major difficulty fitting into the chassis.

Any Suggestions/Advice from some pneumatic veterans?

shorten the ram?

Shorten ram, get a new ram or find the room. Pictures would be good.

Edit: 100 by 360 is massive, shorten it or get a smaller one.

that ram must weigh alot?

Is 360 the total length or the stroke of the piston?

With a 100mm bore a stroke of 150mm maximum would be ideal. Any more would waste gas as the valves could not keep up the flow-rate. The length of the stroke can be reduced by machining the outer tube down and shortening the studs and re-threading.

To give you guys some idea of how big this thing is:

I think what Trev said
The alternative is to sell on ebay and buy another
I sold some rams successfully - thats going to be a heavy bugger to post though
