Deconstructing a Galley
When I put new laminate on the galley top last season I found that the ice box molding was held on the plywood countertop with countersunk #10 screws driven down from the top, thru the out-turned flange on the ice box frp liner unit. Next they had put spray foam over the exterior of the liner, about two inches thick, and it was still dry and in good condition.
Smaller ss counter sunk screws had been driven down into the teak molding that the lid sets into.
Next, they placed the plywood top-and-ice-box on the galley counter and screwed it down (counter sunk again) from the top and then glued the laminate over the surface and thereby concealed all the fastenings...
And then they glassed the part next to the hull... with some tabbing which was lastly covered with a teak cap with its fasteners all plugged.
Next, they cut into the surface and installed the sink and faucets.
As you can imagine, I figured all this out
after I used a heat gun and a lot of long-blade putty knives and other flat metal blade-shaped objects to raise the old laminate off in one piece so that I could use it for a pattern. Some swearing was involved.
Pix of the project are elsewhere in the Maint. Forum.
A decade previous the Ericson shop might have been doing this completely different, but perhaps not too much so. This type of interior detail might have been the same over a long period, it seems like.
I did not try to remove the whole plywood countertop, and did not need to for my particular project. If I done so, the next "demo" step would have involved reaching to the rear with a cut-off wheel on a hispeed tool like a Dremel on steroids -- maybe a small grinder -- and slicing thru the tabbing. Also I would have been working close in under a cabinet. More signs that the interior was originally put together in well-orchestrated stages.
Good luck and take photos as you progress along, and post 'em here.
