    Log Splitter Sanity Check

    Hi all. Getting ready to weld this up and I wanted to do a sanity check.

    It's a 8" beam with 3/8" thick flanges. Push plate is 1".

    Are there any glaring errors before I weld this thing up?

    Do I need to preheat the thick stuff first?

    Do I need gussets on the push plate besides coming off the ram? Does the back side ram support need perpendicular gussets?

    Leave at least a inch before contact with the wedge and put some welds that stick up about 1/4" on the push plate for wood traction.


    ...zap!

    I have 25" from the slide to the wedge. It's a 5"x24" cylinder so that was my 1" clearance. Sufficient?

    I’m sure you will be fine. Only thing that would have been just a little better. Notch out the top flange, and web of the beam. And insert the wedge to the bottom flange, then weld all the way around.

    Looks pretty good from here. Preheat is likely not necessary as long as your not trying to "cheat" using too small of a welder

    I would say ditto the anchor at the cylinder's cap end.

    Too bad there isn't a heavier beam available now... especially the 3/8" flange seems like it may be on the light side.

    Anyway, because of the unknowns of how this thing is gonna groan flex and twist... I would suggest to think about moving the cylinder back so that its cap end is near the end of the beam. That would allow fitting a long vertical anchor that could be tied to the web of the beam. Or is that space reserved for other components?

    Of course moving the cylinder back would leave a "tail" of the beam beyond the wedge. The tail can be cut off later. Meanwhile, after a test run it may be decided to move, strengthen, or modify the wedge's design... having some extra beam there may make that easier. All IMHO, of course.

    As to the push-plate, my guess is that there's gonna be enough power potential here that the overhang of the push-plate -even though it's 1" thick- could be bent by a tough log that's not cut square and loads the push-plate up high. Maybe watch that in action and reinforce as needed.

    I absolutely love projects like this.
    I'd be looking at welding in a few "D" shaped stiffeners into each side of the beam between the top and bottom flanges. One on each side toward the base of the cylinder and another set of stiffeners toward the wedge. If you want to go all out, another set in the middle. Weld the stiffeners all the way around on each side.
    This will take all the twist and flex out of the beam while the splitter is operating.
    Be sure you remove the red iron paint prior to welding. 7018 is your friend here.

    I did have intentions of boxing the beam in under the wedge and at the rear of the cylinder.

    Few years ago, I built this splitter for my brother-n-law. He had to buy the PTO hydraulic pump, and some hoses. Everything else came out of my scrap pile. He has 20-acres of oak trees in California.

    Re: Log Splitter Sanity Check

    I worked on one of those I-beam splitters once. Had to weld up a new wedge and fix the slide. The I-beam was all bent up from binding because when the slide binds up the ram tries to rotate the slide not push it along smoothly.

    Re: Log Splitter Sanity Check

    You didn't say what you were going to use for hydraulic power. If you are using a bobcat or tractor then think about making it an inverted log splitter. That has the ram and wedge on the bottom, This lets you operate it from the seat of the bobcat, split wood on the ground without having to lift it, even use the splitter to load the pickup by starting to split but then lifting log and finishing split over truck/trailer, dropping the split pieces into the truck bed. This makes splitting a sit down job and gloves off split and load truck.

    Re: Log Splitter Sanity Check

    Not sure what you are going to split? my experience On California gnarly Oak and Madrone you do not want "traction " on the push plate.The wood has to be able to move.If it cannot with the power you are generating something else will move. I would also gusset the push plate from the top corners to ram plate. Do not have the ram clevises to tight they need a little slop to account for slight binding. Mine was RR iron with less power generated and it still bowed.
    If you are only working with soft wood forget the above

    Re: Log Splitter Sanity Check

    Another question. In this picture the weld is vertical, but when I was doing it I rotated the beam on it's side so I was welding the outside of the boxing in horizontally. On almost all of these in this position turned out pretty crappy. What is the best gun position to be in for a horizontal weld for a outside corner. It is 1/4" material.

    That is something that is very hard to explain with the type written word. A lot easier to show you. In time you will learn, soon as you start you watch the puddle, and make corrections instantly.

    For me, I would have did it with 7018 stick. Because I know I can make nice welds in all positions with it.

    Re: Log Splitter Sanity Check

    I'm not sold on the 3/8" naked I beam. Mine has a 1/2" thick plate welded to twin I beams side by side. You'll want some triangles to strengthen the push plate, and rear cylinder mount. I would have a frame around the cylinder just behind the beam slide to support the cylinder from folding itself when extended.

    I used a row of 1/2" nuts welded to the push plate to prevent a block from kicking out. A 15 ton I built in 1982? I was testing by cutting a 10" birch in half crossways. It was very green, in June. The bark slipped off. It squirted up, hitting me in the face. Tore my nose away from my face at the top, and I had six cracks in my skull radiating from the open hole where the nose should be.

    Now, barely a scar, but it doesn't flow air as well as it should.

    Ouch.

    Re: Log Splitter Sanity Check

    What's the piston diameter, and maximum pressure? I want a heavier filet, on the rear cylinder mount, and I'd add 1/2" plate down both sides of the wedge to give more opportunity to secure it to the beam. A wider wedge would also take advantage of the two short levers you form almost instantly as a chunk begins to split. A narrow one must slice the full length of the chunk not much mechanical advantage. Overlap one side, weld, then cut with acetylene to form the edge. Finish with a grinder.

    40 years from now, you won't say "I wish I hadn't done such a thorough job of welding."
