Has anyone seen a vintage bone jigging machine? If so...do you have any idea of how it works other than a bunch or shake, rattle and roll? Years ago I saw a video of one working but not the inside of the machine. It really was shaking, rattling and rolling. A real Rube Goldberg. I am fascinated if there is any info out there. I know of an old guy that has one but he protects it with his life.........can't see it, can' see it run, won't sell it. Oh well......What happened to all the old ones lost in the shut downs, banckrupties, etc? Anyone know of one for sale? Thanks.

I saw one in a book, the picture wasn't that good. It looked a lot like a post drill in size and footprint. No idea how it worked.

I went and dug up the patent application. EDIT: wrong URL removed.

EDITED....

It does appear to do shields yes. I think its the same machine.
 
Now....I will just print it out and give to machine shop. 50K later I can jig $4 bone scales. I'll be a millionaire in no time.............
 
George Schrade is only one maker of such a machine. And he loved patents it seems. Bernard Levine mentions on his "knife expert" site that Rogers manufacturing (Rogers jigged bone) has one as well. But I don't think they patented it, so no patent pictures for those machines.
 
I believe the Culpepper company has a jigging machine.
 
i believe there is a vid on youtube of Boker jigging bone handle scales, but i might be wrong
 
It'd probably be a lot easier in making it for yourself volume to use a CNC router and a small ball nose cutter
 
I actually recently was wondering how bone got jigged. I guess the old timey bone jigging machines I imagined up are not a real common thing.

So most older jigged bone was done by hand? There was no standard "bone jigging machine?"
 
Before the jigging machines, bone was jigged by hand- but not the way you think. It was "picked" using a small chisel- hence the term "picked bone."
 
I saw a you tube video of a guy jigging bone with a dremel and a wheel burr. Harbor freight has a diamond wheel burr set for $18 i think, and you can always use their 20% off coupon. I plan on trying this on the plain smooth bone sets i got for free from Culpepper in my latest order.
