Am I justified in my frustration?

It appears you want to continue grinding your axe. You’re now lashing out calling folks turds who have rightfully said your disassembly method is dangerous. Admit it, it is! Yes it’s also frustrating that even a 4x4 couldn’t pull it apart. That’s true too but don’t discount the safety factor because of frustration.

Is there any solution here that will take away the sweat, effort, embarrassment, used shop supplies and tree damage?

What "other" method would you choose? HOW would you get "all that" in a press and HOW would you set it up? I agree, it's dangerous. SO is getting out of bed in the mornin. But don't "JUST" trash the guy's method while not giving him another idea. I've been thinking off and on about it ever since I saw his videos about a better method. WHAT would a port a power fit against? I can think of no way you could rig it in a press. I've just got nothing, so I'm not gonna bash on what he's doing.

He wasn't thinking about the tree. He was thinking "surely I'll yank on it one good time and it'll be out". It wasn't so he kept trying not realizing the tree was damaged until it was. We all make mistakes. He's doing all he knows to do......and I cant think of anything else. If you cannot, don't bash what he's trying to do.

If that junk was mine, It'd go into the scrap pile, because what he's doing IS dangerous now and crosses the line at what I consider safe for my well being. I could just see that axle flying out of the housing right through the rear window of his truck.
