has plans and instructional video for 20.oo or was it 29.99 ,i ferget.
as someone mentioned , unelse you very good welder, buy the ram and I beam unit with cylinder and controls at
www.northerntools.com
$450.oo or thereabouts.
make sure you have a 24 inch stroke.
I think the unit you should consider is the one that mounts on hydralic tractors or fork lifts. they have 2 differnet ones , but get at least 20 tons
ram pressure.
If you can get the 4 way splitter wedge , that is the way to go.... works 3 times faster that a
single bladed wedge. quarters each log in 1 stroke instead of 3 strokes cutting your work time by 66%. 60.oo to 99.oo depending on which 4 way wedge...3 diff ones for diff splitters.
Get a used 5 hp engine from a $35.or $40 lawn mower , so its a verticle shaft , so what.
many new log splitters come with vert.shaft engines Inspect to make sure engine runs well & starts easy and dont burn oil.
A larger engine is a waste of gasoline since there motors run at a constant 3,600 rpm when splitting,or so I was told. I dont yet own a gas log splitter that runs.
Instead of a larger engine , buy a larger or better hydralic pump , at leat 12 gall/min the more gal/min the bigger ram cylinder you can run and the faster the cycle time, for the ram to split log and return.
Two stage gear pumps , I think are the way to go. Talk to northerntools.com salesperson & suck his brains dry then come back here and tell us
!
Hydralic oil resivoir needs to be sized to the cylinder and the floe rate of the pump as do the low pressure pump intake tube, suction into pump. This tube has to be flexable steel braided rubber and of larger diameter that the high pressure return hose.
I bought a 1960 homebuilt log splitter with a shot engine that i was going to restore until i found out it only had a 16 inch stroke and all my wood cut to 24 inch.
That old splitter was only good /appropiate for a 1500 sq ft stove that have 18 inch firebox.
My stove 36 inch firebox 3000 sq ft so I need 24 inch logs.
Intake hydralic oil filter a must , at the bottom of the oil resivoir and a high pressure filter not a bad idea either, 4 the high pressure return line.
U can use either a direct drive straight in line power coupler between engine and pump, if engine has appropiate mounting tapped holes which a lawnmower engine wont. But you could made conversion bracket with oxy/act tourch & plate steel.
Or ,you can use pulley, v belt and spring loaded idler pulley from old lawn tractor, but you need to ask northerntool.com salesperson if the hydralic pump is rated for pulley drive .
Some pumps may only be rated from direct drive , other pumps may only be rated for pulley drive and some pumps amy have a dual rating and can be used either way.
I am not sure but a friend pointed out to me that it makes a difference in the way they construct
the pump, because a v belt puts a certian side thrust (due to the tension on the vbelt) on the rear bearing as well as in the front
bearing of a hydralic pump while with direct in line drive there is no side thrust on either
bearing.
This next sentence got misplaced but I am sure you can figure it out.
So I am buying soon a 20 ton northstar with 4 way splitter wedge.
salvage axil kit off old utility trailer or steal the rear axil from a 1986 dodge aries k car @ your local junk yard.
good luck and let us know how your project comes out .
I started one & would have finished it until I noticed the lack of stroke length of the ram.
that blew the whole project so i gave up. Maybe I finish it some day just to sell to someone with a small stove.
