So basically if it is going to be a part of the loop use epoxy resin. Have you used the WEST system for parts that were in the loop?

Hi Martin-

I’ve made many homebuilt Rebreather (and homebuilt airplane) parts w/ West epoxy. To date, I cannot recall making any loop-contact parts with it, but do have plans to. Specifically, one project I’ve been thinking through for a while is my version of a lightweight (for air travel) composite Meg can to fit my short radial Meg scrubber.

Right now intention is to do layup with a 50-50 carbon fiber/ Kevlar cloth using West epoxy. Goal is to build part under 2 lb and will shoot for under 1.5 lb or so. It’s getting into dive season here, so earliest actual shop work would be next winter. Summer up north is, as you well know, time to dive! (and to keep the house from falling down around my ears

).

Main resin will be West’s workhorse, #105-B. For hardener, I plan to use their slow cure hardener #206-B. That combination yields a version w/ a nominal 45 minute pot life and great hand layup properties. It will also work well w/ the various thixotropic additives (glass bubbles, micro-balloons, flocked fibers, mill glass, etc) folks who work w/ this stuff use for various purposes.

One accessory West sells that I highly recommend should you choose their product line is their metered dispensing pumps. They make getting the correct ratio of resin to hardener a snap. Cost is only around $10 ~ $15 each. They are just a simple hand pump that screws into the top of the can in place of the can’s cap. One full stroke of each into your mixing cup and you have a perfect ratio of resin to hardener to blend up and work with. They also save a LOT of time.

Ditto on the pump suggestion as you will pay for them in wasted improperly mixed resin over the course of a gallon ( about 50 bucks plus 25-30 for hardener ) otherwise.

Steve & everyone else,

thanks for the tips and good luck with your projects

BTW ISC had a plastic looking can on display at BTS, not sure of material, but was real state of the art composit, might be worth a phone call.
