I’ve had this Iron & Oak 22 ton with 4 way for 12 years now and have put at least 1500 cords through it. As time has gone by, the post the removable wedge slides over has slowly bent back some due to the repeated pressure put on it while the 4 way was on. As a result, the 4 way was tilting back some which lead to it rising up and popping off somewhat frequently. So I had another spacer which regulates how high or low the 4 way sits cut like this to alleviate the problem. Thankfully it’s working like new again. Glad it was basically a free fix. Side note, I tried putting pictures in order that made sense but they came up in random order but you can figure it out. Haha
Those posts have to handle a lot of force when using the 4-way. On mine, the base plate where it attaches to the beam was slightly bent when I bought it. I managed to straighten it out and used quality bolts to keep it tight. I use the post to mount my split table. It’s nice to have.
So that spacer was designed to just sit on the lip of the higher metal and float on the other three sides? That’s poor engineering.
That spacer slid down the post and sat flat before the post got bent over time. I have spacers of different sizes so I can control the size of the splits that come out under the 4 way. Not sure how that’s poor engineering
I’ll assume that’s the bad spacer position that causes the head to fly off? I’m referring to the surface It sits upon. Those gussets could have been raised and welded with a heavy bevel joint then ground flat. The spacer would then have a flat surface to sit upon without the need for a relief cut. JMO. Those spacers shouldn’t take much abuse anyway. maybe you have a higher spacer that can no longer “take the corner” on a bent pole? Do they slide up and down with the wedge? I see no reason they should but.... If the problem of the wedge sliding off continues put a washer or two between the two bottom mounting plate bolts. That should bring the pole back to square. Won’t fix whatever’s going on with the spacer, just square. Wish I could say my splitter performed 1/4 as admirably. Pretty much rebuilt it from the ground up the first year. Everything failed
