FDM printed hand crank jamb peg V1

My new project was to come up with a hand cranked portable jamb peg and also to be useable on my low profile base
Since I started 3D printing indexers for my other jamb pegs with a resin printer I often wondered if it would be possible to print a usable faceting machine, The build plate on the resin printer was fairly small, fantastic detail, but print size small. So bought a FMD printer so I could print larger pieces. The prints turned out better than expected, so went ahead and started doing the drawings. There were certain aspects of the machine I wanted which aren't available on the others, So apart from the radius of the quadrant the drawings were done on the fly.

Hand crank jamb peg timber base V1

The base of this machine is just a piece of shelving. The bearing mount, platen and crank setup are all printed. There is no weight on the drive wheel so won't free wheel. For smaller stones where there is not too much material to be removed it's quite pleasant to use. larger stones are not so easy as material removal is more time consuming so now it becomes work! But over all it's workable.

FMD Printed Jamb Peg Metal Base V2

Version two, modified the quadrant and side arm, updated the side arm to accept a new rounding pre-former, can now use 8mm and 6mm dops. Also added a hard stop. I will use this configuration for testing.

FMD Printed Jamb Peg Table Adaptor V2

The tables adaptor on both the Israeli and Indian Som jamb peg machines come with an excellent table adaptor. Rigidity and warping is the let down with printed parts, so had to come up with another method. The unit in the pic is working, not perfect but will do until I find a better method.

FMD Printed 'Mechanical" Style Dops

Printed these mechanical style indexer dops in 96, 96x6, 64 and 48. Off the shelf 6mm round aluminium for the sticks, Just tried a couple of crowns in wax, facets all in the right position so happy so far.
