Works nice Goran. Looks like the last few inches does all the work. Could you make it shorter and still work?

Yes, about two last turns does most work, probably half of the screw would work also.
If i put in maximum thickness its built for, all of the screw would work.
I’ve started build kind of a wedge out of thick angle-iron, to be mounted against the anvil, to direct the wood along the screw, but the tests worked so well, i never finished it.

In fact, there is a lot of friction when cutting hardwood, so it is good to have the final knife do most of the cutting, cutting in the style of a Wayne chipper, while the spiral of the screw ensures even wood feeding, and the geometry of the funnel of the inlet opening bends the wood, where the bending force presses the wood against the spiral, which is important for continuous feeding and perhaps slightly easier cutting…

That is great engineering Tone, i totally see what you mean, the perfection of the screw chipper 😃 👍

Tone: The propeller must drive the wood at a speed that depends on the screw pitch. Would you recommend a particular screw pitch for this construction?
I can’t wait to see how you finish this build.

Screw pitch determines chunk size.

I made this kind of hatchet today, no real quality work, no real forging, just cut and welded a old lawnmower blade, and put it on a spare axe handle.
Going to try it out for de-limbing, get of twigs from the thin stuff im going to run through the chip-chunker, before i forge a real/better one.
This is only grinded real sharp, going to run it on the “stone” tomorrow, to get it REALLY razor sharp.

Goran, are you left handed? Is that the reason you ground the left side of the blade? I am right handed and I would have sharpened the right side of that blade so it would follow close to the trunk better.

You got an eye for details mr Don, yes, im left handed.
But i actually sharpened both sides, it’s a test, i don’t want it too aggressive in the cut, so it not “dig’s in” in the trunk, something like a wood-carving chisel.
Have to test it out, if i feel “tired” in the wrist after use, im going to experiment some more.

That looks really nice Tone 👍
Very sturdy construction.

Great work Tone, super-nice 👍
Now i can’t show my screw-chunker anymore, i have to hide it away… 😔 🤪

Sorry Goran and thank you, I feel a little rude for intruding on your topic, your wood chipper works really well, you don’t need to hide it… 😃

First, you get style points for the triangulated rear bearing mounting. It looks cool. 🙂
However it will probably have to be somewhat covered up since the chips are not all landing in the wagon.
Is it actually pulling the brush in or did you have to push it a bit?
What is the spacing between the flights? it looks about 8-10cm. But I have to ask.

That looks like so much fun to use. It all looks very professional and well build. I really like how compact and simple it all is. And mounting it on that trailer really makes production streamline.

Tone and Göran - you two have great fab skills, but above all impressive determination.
