I have started the backbone laminations and applying epoxy coating to all the plywood cuts.
I am using West System Epoxy. West System is very well respected and is widely available in my area. I was able to pick up a gallon of resin, both the fast and slow hardener, and several types of filler for different applications on the boat.
After applying several batches of epoxy on the frames and backbone pieces I am happy with the performance of this epoxy. The 5/1 pump metering system is very easy to use. Simply one pump from each of the containers and the mixture is correct. I added silica thickeners for the laminations of the backbone. Using a serrated scraper I was able to apply a thicker coating of epoxy then I used for general sealing purposes.
