Finish Sanding & Sealing Bulkheads

Back at it today, my Mach II Bulkhead 4 is completed & just needs sealing. Sealing, for me, means giving both faces two coats of thinned epoxy resin. I reckon a few hours work, with drying times in between, are all that's needed to complete this part of the build.

Here you see my pile of four bulkheads (B4 on top - not sealed) & transom. My Plans book is there too, I just printed everything on recycled A4 paper & wallow in the "Apple-like simplicity" of this build.

What you may not see is that these parts are made from 15mm ply instead of 12mm. I found all the locally available construction grade 12mm ply to be warped. On the hull's Side Panels I am going for Marine Ply because I reckon that being in contact with the sea & being susceptible to damage, I prefer that luxury. I'd have to say though, apart from a fluffy surface, I am pleased with the quality of construction grade. If it's soaked in epoxy inside & out, I can't really see the need for marine grade. You'll make up your own mind, that is, what your fear of the sea demands & your pocket allows. Each to his or her own, as long as you're building or sailing who cares?
