Nut cracker

[12bolts]

Final assembly. Going to busier than a 1 armed paper hanger getting this glued and clamped with everything just right and no glue getting on bits that it shouldn’t be on. I superglued the bristle strip to the top of the bearing block as well as some hot epoxy to support where the bristle strips overhang.


I finished it with tung oil and in a few weeks, after it has dried properly it will get a coat of carnauba wax and orange polish.

To keep the force required to crack the nuts down I designed the cam for limited travel. Because of the limited travel I needed to make the opposite half of the cracker adjustable as well. Rotating the thumbwheel moves the bolt in or out to suit bigger or smaller nuts.


And a closeup of the bristle strips, which seem to be holding their shape reasonably well, but it’s still early days.

And the nut on the other end of the handle. Works well. And the best part? She is happy with it

I really like the design of the nut cracker,Phil. Is that something you came up with? The limited stroke is what is required, so as not to smash the nut meat. The adjuster nut on the other end always keeps the stroke in the right place. Very cool. )

Marcel,
A little while ago I had stripped a brush cutter I/C motor down to get the ally parts out of it and the itty bitty crankshaft and con rod gave me the inspiration. Originally I had thought on making it a crank operated cracker but then I decided a cam would be simpler to do. But to answer your question, yeah its just something I came up with. I dont recall seeing something like that before but maybe I was channelling............

Cheers Phil

Awesome project. And since the Ministry of Finance approved the final result, you should be able to add at least one more tool to the collection
