that was the original plan Doug, but there's just not enough room - I did the calculations. At 700psi (powersteering pump) it will lift 0.17 tons, and push down 0.24 tons.. With a decent geared pump (3000 psi) it will lift 0.74 tons and push down just over a ton.
I think 700 psi is a good start point, that would lift me at the end of the lift arms
I've got 4 10l -3/8 bspp fittings already, but they are the same at both end have you got some with metric thread on the other end?
used some more of those brackets today to make part of the front three point hitch, plus turned some 19mm bushes down.
cheers
