ArboristSite Operative
my first post. i've been trollin this site for quite a while researching splitter builds and just enjoying reading about what other people in the wood heat thing are doing. great site! now for my proposed project. i plan to build a splitter/ home processor type rig so i can handle big wood alone. i plan on using a 5x24 cylinder with appropriate pump. most of the cylinders i can find have -8 or 1/2 npt ports. those splitter calculator thingys give all kinds of great cycle numbers with big pumps and 5 inch cylinders but my contention is if you can't get the oil into the cylinder because of the 1/2 port, what good is the big pump? how much flow can i realistically expect through a 1/2 fitting? how much for a -10 or -12? i'm talking real life at around 400 to 600 psi where i understand most 2 stage pumps operate until the low flow stage kicks in. how much difference, timewise between a -8 fitting and a -12? as most of you likely know, there is quite a price difference when you go for the big stuff but if it's worth it i may have to bite the bullett and go with the big port cylinder with the appropriate pump and plumbing. sorry to be longwinded but reading this forum answers a lot of questions but opens up a big ole can of worms too, lol.
