The Rimspoke Nutcracker

[RIMSPOKE]

I HAD THIS LATHE & MILL PROJECT KICKING AROUND IN MY HEAD FOR SOME TIME .
IT IS A SELF ADJUSTING NUT CRACKER / IT SIZES THE NUT & THEN CRACKS IT .

IT WORKS WITH TWO OPPOSING BRASS CUPS THAT MOVE TOWARD EACH OTHER
ON PARALLEL SHAFTS BUT AT DIFFERENT SPEEDS .

THE FAST CUP IS PULLED FROM IN BETWEEN THE TWO RAILS .
IT HAS A LARGE COUNTERSINK ON BOTH SIDES OF THE PLATE IT IS MOUNTED TO .

BECAUSE THE NUT IS ABOVE THAT CENTER , IT CAUSES THE PLATE TO TILT
SLIGHTLY & LOCK IN PLACE LIKE A SCREEN DOOR LATCH .
A SPRING ALLOWS THE MECHANISM TO CONTINUE IT's MOTION WHILE THE PLATE DOES NOT .

THE SECOND CUP IS PUSHED FROM BEHIND WITH A HIGH AMOUNT OF LEVERAGE .
IT CONTINUES ON IT's COURSE CRACKING THE NUT AGAINST THE NOW STATIONARY
OPPOSING CUP . BRASS GUIDES PREVENT IT FROM LOCKING LIKE THE FAST CUP .

THE INVERTED CUPS PROVIDE A RING OF PRESSURE ON EACH END OF THE NUT ,
BURSTING IT IN A BARREL SHAPE . THIS SHATTERS THE SHELL RADIALLY WITHOUT
CRUSHING THE EDIBLE PART INSIDE . THEY COME OUT WHOLE .

LIFT THE LEVER AND BOTH CUPS RETRACT TO THEIR END OF THE RAILWAY .
BEST TO USE IT ON A TRAY , IT CAN SMOKE THOUGH A LOT OF PECANS .

I MAKE THIS STUFF UP AS I GO . THIS ONE DATES TO 2011 .
I NEVER MADE ANY DRAWINGS . I CAN MEASURE & REVERSE ENGINEER I SUPPOSE .

THE ALUMINUM PIECES WARE CUT FROM A PIECE OF `1/2" JIG PLATE .
THE RAILS ARE 10mm STAINLESS RODS .
THE BRASS CUPS WERE MADE FRON 1" BRASS ROUNDSTOCK .
THE HANDLE WAS JUST SOMETHING FROM THE JUNK DRAWER .
