Someday she'll be no longer a pile of plywood - that will be 'two best days' rolled into one. I remember being terribly excited to start this CS17 and I'm sure I'll be equally stoked up the day I can get away with saying she's finished.
That same day (or close thereon) I'll start a larger boat, with a cabin. And then that's it, the end of my boat building career. Except for a dinghy. I have a dinghy with no class at all, a recycled plastic thing. It's nice, but it's not something I made. So, no more boat building with the exception of a dinghy.
Given my wife's horror of heeling (darn it), we might someday want a small power cruiser. Not sure I could handle building anything like an Outer Banks 20, but something (arg!) without a sail would please my wife. But after the dinghy, the power boat, and maybe a larger camp-cruising sailboat...
When I first got my CS17 kit there was a pile of disposable small paint mixing trays marked down at the local Wally World. They were about five by five inches and worked well for mixing up to about three pumps of epoxy. Maybe more, but I haven't needed to work with larger quantities.
In retrospect I probably shouldn't have used them. Epoxy bonded to the tubs. I never noticed the tubs getting soft from the epoxy but since it was bonding it's possible the epoxy was picking up some of the chemistry of the tubs.
I finally ran out of them, and being a creature of habit I went back for more. Wal Mart no longer stocks them, so I got a three dollar pack of 'Gladware' food tubs as an experiment.
Hefty contractor garbage bags have zero adhesion to epoxy, so I use them quite a bit, and the food tubs had that same slick plastic feel.
Sure enough, cured epoxy comes right out of them with no visible effect to the plastic so the Gladware tubs are reusable. Here's a picture of a tub with some epoxy left in it, mostly squeeze out I scooped up. The bottom photo shows the same tub after the epoxy popped out like a casting out of a mold.
