alternatively you could use to smaller 50 bore rams together

2 50 bore rams is not as powerful as a single 100mm bore unfortunately, you'd need 4. pm sent about the ram btw.

If your looking at a front hinged, UFO uses 2x 63mm bore 200mm stroke low pressure rams. I have a feeling Firestorm were 50mm bore rams (2 of), Envy did run a single 100bore ram. It all depends how much power you want.

Our 100*300 ram came from ebay for £40, so they are out there. Just keep looking.

Weight?

Light enough once we'd machined it down to 160mm stroke and replaced the piston rod with some blagged titanium bar... Weight wasn't as much of an issue as price at the time...But it still managed to win the uk champs.
