When I last (2004) visited the Geode Kid (RIP Robert Paul Colburn, 1936 - 6 Nov. 2013)
RTH
The Baker Egg Mine.
I got a copy of his first CD, then he sent me a copy of his revised edition. In one (both?) he mentioned his geode cutting jig as "two 2"X4's hinged like an alligator's jaws" that he dropped the positioned geodes into. The wedge kept them from moving, and one size fits all! Two second change out time! Take out the last, drop in the new, and away they go. He used the design in many saws for many years.
Unfortunately I never saw them.
Well, lo over a decade later, I just finished designing my version that I will start building tomorrow - with modifications as I go.
Hey, It works for pill-splitters, it'll work on eggs!
The first one is for my Roth Trimsaw, for small (1" - 3") eggs. The table end assures I won't cut too far.
the second for my 20" Slabsaw for bigger game. - - - Be sure to set the cutoff switch.
I hope the drawings are self explanatory. Size the base for your saw. Mark the biggest size egg you want, cut the slot, and fit the 90o bracing to the circle. The 90o sides assure a tight fit somewhere for any size egg.
The sides and bottom act as three vice-points and the saw blade locks the egg in place so it can't move around.
