Ok - So I'm not going to completely explain what I am doing ahead of time. There are two reasons - One, it is a work in progress that I am collaborating with a friend on, and two, it's more fun this way
So to start off, the main focus is on the "frame", also known as the counterlung case. My main focus is on hardening the structure for all around diving with a focus on cave and wreck. In doing this, it must trim out with no additional weight.
To start, I checked the CG of the entire unit:
Next, I measured and cut the raw materials. For this project, everything is .125" stainless:
The thickness was selected for it's weight given a drysuit diver.
The aluminum spine from the original CK was used, and the new pieces where drilled and chamfered:
The new "spine" will be much tighter, and less involved (keeping with the KISS principle
):
The head with the spacer in place. and measuring for the cut-outs for the "optional" back-mount counter lungs
Also measuring the position of the "ring"
And the cut-out's done for the "optional" accessories:
Here she is after a day's work:
In the next couple of days I'll finish the welding and other fit-up. Check back soon.
