I disagree with the above. A 20# pot will maintain heat better if you are adding back lead as you go.

I have been doing this for a really long time. Currently, most manufacturers of crankbaits are using 3D printers to make prototypes. They design the lure using a software like or similar to Fusion 360. Fusion 360 allows you to design a three dimensional lure and output it in the proper format to print one on the 3D printer. My printer can print ABS models perfectly. I can control all aspects of the design and have the flexibility to make any changes I might find necessary to achieve the desired result; buoyancy, wall thickness, ballast chambers, hook hangar location, etc. etc. Not that many years ago, it would take thousands of dollars to make a prototype. I can do it now for a couple of dollars in materials and a few hour of design work on the computer. If you would like to know more, email me.
