Hello all.  I'm just wondering what peoples opinion on the size of "h" iron that should be used as the main beam where the ram is attached to


Is it the case of bigger is better.

I have a 6ft length of 8" x 8"   10mm thick. H iron.  I think myself that is plenty.

What do ye all think
Thank you

There are a few variables that need to be considered, what size ram, how much pressure and what type of wood, what kind of wedge, just to name a few. I have a 5x5x 3/8 with a knife wedge and it works ok, I believe that my valve is a bit on the weak side and I have stopped the ram dead in a knotty piece but I figure that's my insurance policy rather than
davesomething apart.

Thanks for the reply



Just an update.         I got a 2.5m long, half inch thick web, "h" iron the other day.  :)

My theory is the stronger the steel is the better.     Just my opinion.

The 8" stuff should work .

Fact being as I stare put my window from where I am making this post are two splitters .One is my homebuilt which is over kill with a 10" wide flange 72 pounds per foot .The other is a factory built rated at 28 ton,a lie of course but it has an 8" beam .

Actually if you use a knife edge which doesn't put as much strain on the system you can get by with less heavy steel .I also have an electric unit that only has a 4" beam about 3" wide flanges ,no problem .

I like the idea of drop on wedges that fit over a welded on knife. With this system the knife could be used for hard splitting wood and a wedge or four way could be dropped on in easier wood. Not my idea, saw it somewhere.

I am useing a 5 in top 8 jn web all 1/4  with a 4 in cylinder  relief set a 1700 the beam flexes alot if I stick the wedge . I think I would start bending things if i turned it up much more . Hope this helps . Gearbox

I build my splitter around a W10 x 33lb beam. It's 10" tall x ~8" wide. The top and bottom 'plates' are ~7/16" thick and the web is ~9/32" thick. I have a 5" cylinder with a pressure relief setting of 2000 psi. After many dozens of chords ran through, I've had no problems.

I built one about 35 years ago with a 8" 18#/ft house beam. I was young, the beam was free. I should have given me problems by now. Nope, I'll watch it flex and twist a little, but I'm still waiting for it to fail so I have a reason to build another one! It has a (about) 4" x 40" cyl. from a forkilft junkyard in it and pushes a wedge (it can be used vertical) that is about 10" tall. I'm still amazed that I haven't bent it up in all those years.

(op; either of your beams will be fine!!)
