That is a really good idea. The lowly forklift has so much potential. I was thinking of scavenging parts but with being on an island, the yards are just too hard to get to so it's mostly going to be new parts. I'm also kind of done with having to repair everything. It seems to take so much of my time. (that sounds silly since I will spend a huge amount of time building this from scratch) Also, there are so many deals to be had, I can't resist the shiny shiny.

I found a site that has charts to calculate piston velocity, force, etc.:http://www.haave.no/pdf/FactsWorthKn...Hydraulics.pdf
My pump is 24V, 5.4 hp with two pumps: a two stage pump 3.5 gph / .9 gph @2000psi and a continuous 2.5 gph pump which I don't have a use for yet.
According to the charts in the preceeding pdf, my pistons will travel at .07 m/s which sounds pretty good. Not racing along but fast enough for me.
