Back in 80-82 dad and I built a wood splitter... one of the first around here.. anyway man its heavy.. I think its made from 10 in H beam with 1/2 or 3/8 flange thickness.. it will strain you to hook it up to the truck..lol.. well anyway it has been sitting for 10 -15 years and i'm wanting to re vamp it.. would like to made a 35-40 ton splitter.. IIRC it has a 2 stage 11 gpm pump.. no cylinder no motor and the valve is frozen I think.. I have a 12-14 hp vertical electric start briggs i'm going to use on it.. what cylinder, pump, and valve do you all reccomend? like everyone i'm looking for high cycle time and plenty of ump.. it has the splitting wedge welded to the end and had a pushing block on the cylinder.. thanks!
