Often thought this would work well - but what stops the log from falling over to one side as you are lifting it?

Looks like just a farm jack with the top taken off. Used one recently when disking up a big beech. Handy as anything. Stuff didn't roll about but it was big .

Farm jacks are about 45quid like

Yep I've been using them for a while - but as you jack the log up I've always found it tends to fall over one way. They say the base on these is different and stops it from rolling sideways but it doesn't look enough to stop it from doing this.

Falling over because of the instability of the stand itself or because the point of attachment fails to hold it in the log?

 

Looking at the video and photos, it doesn't look that well designed to get a great grip of the end grain (the end grain of down-a-while sycamore is usually getting soft) particularly something freshly felled or like oak. It doesn't impress me that much.

The beauty of farm jacks when used for vehicle recovery is their instability, allowing you tojack up and push the jack sideways out of the ruts or onto fresh ground.

They can also be lethal in the hands of the unwary. I have a mate who was lucky not to have a smashed jaw when he got smack in the side of the face by the handle while it was under load.

When I was looking for a tree jack I came across it. I have a High Lift anyway but could see a heavy stem coming away or toppling uncontrolled on my mill or foot

We used these to level logs for the lucas mill, we just cut a shallow step in the log first. It was a simple 50 quid jackall. You can control the sideways movement to some extent by holding the top. As we were only lifting to place chocks under there wasn't very far it could go.

Don't let go of the handle when lowering, good fun to watch but not fun if your anywhere near it.
