Two weeks in the making but the coils are finally moulded. All the dire predictions were circumvented

and judging by the on screen scale my estimate of 1/8 inch (3,2 MM ) coil rods was pretty accurate afterall.

The biggest problem is I overestimated the size of the gun. The onscreen gun is 18 inches (46 CM ) overall

Whereas my coils could work on a gun upward of 20 inches but I made the coil extra long to allow for selvage. BTW Nature does that on the DNA molecule and is the reason we age.

Suffice it to say I am pleased with the outcome.
