How does charcoal perform in a wood gasifier?

I have heard about birch syrup, but never tried it. I remember cutting black birch and it smelling like root beer. That would have made an interesting syrup! But I never heard of walnut syrup. Unfortunately I haven’t got those species here. There is a laurel tree here that has an interesting aroma when cut, but can’t imagine making a syrup from it.

I would have to verify it but if i remember right you can make syrup form corn on the cob

Here is the diagram of the crusher I promised. I could not get the exact dimension of the position of the pivot on the lower jaw without taking it apart, but it is very close. Any variance can be made up in positioning of the other pivot point on the wall. All dimensions are in inches.

This animation shows how the crusher works:

I still plan to make another in steel with a larger motor and double pulleys. Not sure when that will happen, I am in the middle of a house renovation, car engine rebuild and soon firewood splitting for next year. Luckily I have the trees down and cut to log length already. But all that stuff really cuts into my gasifier time!

How far is the gap at the bottom between the moving jaw and the static jaw when it’s as close as they will get?

The animation exaggerates the movement, so at its closest the lower jaw is 7/8 inch from the static jaw and at its furthest it’s about 1 3/8 inch. I measured this from the flat part of the jaws. The teeth stand 3/8 proud of this surface, so these distances shrink. The teeth are staggered so that each tooth on the moving jaw is opposite a valley between teeth on the static jaw, and vice versa.

Martin,
Thanks for the drawings and information. I may give it a try.
