I'm not sure about that tbh. It's a total perfect fit with a slightly raised groove to make sure it has there is no movement, it would end up rounding the edges if it was not so perfect. I agree that the trewhella design is alot better and maybe that's why you don't see many of these about anymore because of the bad design. I'll know for sure soon hopefully, I've managed to get a 27 page manual printed from some historical library in Derby. Just waiting it to get here. For now tho I've sent the bar to a blacksmith who is going to copy it and make it 8 inches longer and solid forged bar. He is going to reweld the old one aswell. See how they hold up and if not I'll have to pay up for the broached square.

Doubters can doubt all they like. I like to learn my own lessons. Maybe other people will have a try after that video on youtube. My brother knows a professional welder and is gonna get him to have a go at it like kevm suggested. I've also found a blacksmith that say they can make a copy for £50. Will keep the thread updated. Worst thing is after pulling up that stump it breaks on a measly hedge lol. Must of phoned 20 different places today trying to get it replaced, 350 was the max ?.

This thing I'm using is must weigh at least 60-70 kg (maybe more) my brakes were really bad on the way back home lol. I'm a firm believer that the older stuff is less likely to break (Bad time to say that). Are these tirfors as strong as they say? I hate stuff that breaks on the first day.

Can't believe this has just happened. Gutted. I was loosing so much weight and enjoying it. Any suggestions? Would a good welder be able to make this strong again? Or anyway to get a new one made?

I wouldn't like to do this again unless I become a bodybuilder...

I just told you it's to save money and you still wanna talk like this. My motives are history, education and saving money. I'm not challenging your knowledge...don't reply, other people want to see.

You don't know me buddy. I have a massive garden and a good place to burn it. I've got alot of older smaller trees and old fence posts to pull aswell. This will save me alot of money. Maybe you're rich, I'm not. Just had large pond dug aswell so plenty of extra soil, so will save me getting a skip. You don't have to watch the video if it offends you.

Would you/anyone be interested in me filming it and putting it on youtube? There's not alot of information about these machines and I'd like to make tutorial video of some sort just for fun really.

Couldn't I just use a 10t sling on the stump aswell? Is there an advantage of using a chain? Thanks

So is my maths is right, I just missed k?

My maths got a stump of 14.7 inch in diameter needs 106 Newton's of force to be vertically uprooted which is 10.8 tons?

Can anyone understand this chart in in tons. I know it's for vertical uprooting but can anyone figure out how many tons for a less than 20 inch diameter stump? Forces required to vertically uproot tree stumps - CORE Reader CORE.AC.UK

I was told by the guy I brought it off that he had pulled bigger stumps than this buy just leaving it tensioned over night then try get another click on the cog everyday. He got up one morning after it rained and it had pulled itself out over night.

Yes, it should say monkey winch lol. I'll change that now. Yes it's just like the truewhella with 10t load. I just can't see how that old grubby stump could out anchor a healthy tree that is alot bigger in diameter. The anchor tree is also on higher ground which might give me the leverage to pop it out. Really appreciate all the advise guys.

I'll have ago with the winch but if not then I think I'll have to get a grinder in. I still have about 10 concrete posts to pull out and some smaller trees so it should still be useful to me if the stump doesn't come out.
