We just brought the Cape Horn wind vane and the Frigoboat refrigeration units down to Senta to start both those installations ASAP. We just about finished the windlass installation and only have cosmetics left to do, some are not insignificant: http://www.grenander.com/Senta_II/B...rise_when_replacing_forward_cleat_(Sven).html
When doing the new refrigeration and insulation I think I have it pretty well thought out, but I'd still like a sanity check.
We'll be adding 2" - 4" of insulation on the sides of the ice box compartment (Home Depot pink, non absorbing closed cell). We'll probably add up to 6" facing the outside of the hull and also 6" on the bottom.
I have two main questions about the installation that I'd like any second opinions about.
First, I've been considering placing a sink-type trap in the bottom of the box. In other words, a pipe that goes down and then curves up before going back down again. The idea is that it would hold some amount of condensation water in the trap so that cooled air would not flow out of the fridge through the hole to the bilge but at the same time it would allow the box to be rinsed out from time to time, or just defrosted. Would we be better off just putting in a simple straight drain with a drain plug ?
The second question has to do with sequencing the work. Right now I'm thinking we'll do all the insulation and internal box work first. After that we'd cut the holes and route the compressor tubes etc.. Is there any reason to reverse the order and pull the tubes and wired first and then build the insulation around them ?
Ok, I'm cheating ... I have a third question. I'm planning on lining the inside of the box with epoxy sealed plywood which is glued in place against the insulation and then glassing the interior corners for a water proof seal. If the cut pieces are sealed with Smith's Penetrating Epoxy and not cut or trimmed after that, is there any reason to use marine grade plywood ?
As usual ... thanks.
