Project Description

I have an idea for a spring powered speargun that would be ideal for my purposes, but nothing similar is available on the market.

The design will include a compression spring with tension that will require a windlass or similar to load. Design of appropriate trigger mechanism and projectile also required. Will be used in salt water.

Full description by way of Skype discussion and scanned sketches. I have the idea, and I have people capable of putting it together. I need a contractor to conduct formalised device design of the prototype.

I need an engineer to conduct design work, including materials specifications (e.g. spring tension, salt resistance, optimal barrel length, aluminium/steel/other components), full precision measurements for all machined parts, produce exploded parts diagram.

I have a fitter-turner/machinist ready to build primary elements of the unit once precise designs are provided.
