[Milsurplus] Worm Drive

[Bruce Gentry]

Have you checked into 3D printing?  If you gave  the shop a  proper 
file, the cost could be reasonable. They might also be able to 3D scan 
the original part for you and edit out the defect. Aside from cost, the 
big issue is whether the material used for a 3D print would be strong 
enough to take the load and wear well, and whether the printing process 
could give a suitable finish.  Mabye not yet, but the time is coming and 
will be here sooner than we think.  I am considering this for a gear and 
the dial mask missing from my R-274 receiver.

No matter what you do, unless it’s stock it will cost quite a bit of money. If you have it drawn up in 3D CAD (.stl is a nice format)  that will help the process along. If they have to draw it up first, count on a bit more money spent.
