Hi guys. I am tossing around the idea of building a spitter. Some background: I don't really need a splitter, and can't justify going out to buy a new one now. However, I have an old John Deere B two cylinder tractor that hasn't seen much use in, well, a long time. I'd like to give the old girl a job to do and wouldn't mind spending some time in the shop with the old man (he gets cut to 40 hrs/wk in the winter and hates it) building a splitter. So, I'll admit the main reasons for building the splitter are to have a new toy to work the tractor and to play in the shop. Here is what I am dealing with: -1393 Deere model B. PTO is rated at 25 hp, it does not have hydraulics or three point hitch: http://www.tractordata.com/farm-tractors/006/9/8/6988-john-deere-b.html -I'd like to get a pump such as the following (ebay link just below). The standard sizes seem to be 11, 16, and 21 GPM. I am thinking of the 21 gpm because difference between it and a 16 is rather small (within $40), and with a larger pump I can run the engine at a lower RPM to get the flow. While these old Deere two-bangers are rather easy on fuel, it'd be nice to run at a lower RPM. What do you think on the 16 gpm vs 21 gpm? Also, there is Prince Pumps (such as the one linked below), they seem to be the priciest pumps. There is also a "Chief" brand which seems to be a tad cheaper. Though, I admit the one on ebay below is a really good price for a new Prince. http://www.ebay.com/itm/New-Prince-...Pump-HC-PTO-1A-21GPM-540rpm-NEW-/360702095463 -I hope to find an old splitter on craigslist, typical tow-behind model. I've seen some older ones that have the cylinder, I beam, and axle/frame, but no motor/pump in the $150 range. This would be the ideal setup, if not, I would build from scraps I can scrounge up. -If I build, I'd go for a 4 (5?) inch cylinder with a 2 inch bore. Thoughts? I'd probably go in the 24 inch range, as a 20 would cut it close on some of my splits. -A buddy of mine welded up his own reservoir tank and would be willing to weld one for me. I've seen the rule of thumb being "match the gallons of your reservoir to the gpm of your pump", thoughts on this? There is a lot here, hopefully some of you can chime in. I think I can do this in the $800 range. Yes, that's getting close to buying a new one, but the added bonus being that I can use that $400 pump for other things on that tractor as well, increasing it's utility. Andddd, I can play with my tractor. So, it's also about fun!
