Hello Guys and Gals - I'm new to this forum and lure making in general, although I am not new to fishing or rapid prototyping. I think I can provide some avenues of support for this topic from my design engineering background.
One option for subtractive machining (CNC) would be a small, low horsepower tabletop unit. Ive had my eyes on this model for some time now. DIYCNC.com
For under 1000.00 you can have a prebuilt unit ready to go (minus software)
Another option would be calling a rapid prototyping firm (SLA, FDM, etc), I use Laser Reproductions here in columbus on a weekely basis. Great guys and pretty cost effective for making molds if you value your time at all. Google them and check out their capabilities.
Here's the catch, no matter what you will need a CAD file to send to your own machine, or a rapid prototyping firm. I dont want to break any forum rules with this post by selling my services or advertising.
All I will say to you is PM me if you would be interested getting help making molds, baits, or CAD file generation. I am in process of taking someones carved bait and recreating it in CAD so that a master can be made as well as a mold. I essentially do this process for a living, just not with fishing lures but maybe someday!
Here's a couple pictures of what I have done with a couple of my own designs, these are built with a 3D printer(google it if your new to this technology!!). First timer here, be gentle haha
