Pat's 1:16 Elco 77' PT


After doing that smallish 1:24 display model of a late Elco 77 PT, I'm now jumping into an R/C version in 1:16, using the same basic plans scaled to suit, with a wood framed hull covered in dual diagonal planking, and a lot of 3D printed content above. Model will be 58" long with a 15" beam, and should weigh about 22 pounds.

While I rail against the perceived "necessity" of waterproofing model boat interiors and usually leave my models bare inside, I do appreciate a nicely finished interior when it's appropriate... and I decided it's appropriate here.

Just painting wood leaves it looking rough, so I want to lay down an epoxy coat first, followed by sanding, followed by a nice coat of white paint (just like the real Elcos). But sanding a finished model boat interior is nearly impossible... so I'm doing it BEFORE assembly. I'll coat all the interior parts (including the planking) with epoxy, sand them, then assemble them... and only spray the interior later with paint.

I tried this once with lacquer... not a good idea, glue doesn't adhere to lacquer! But epoxy will work just fine with CA and epoxy glue.

Looks like a CNC cut kit. Very nice. Who made it?

Thanks! Me and my trusty 9" bandsaw.

But see the link, there is CAD behind it... but there was also a line at my usual laser cutter, so I made saw dust instead.

Looks like one of those wooden dinosaur skeleton kits you get at museum gift shops.

OK, a little more order to things here. The resin is still curing on the keel...

Finally, grew a spine!


Ready for stringers and planking... which is a lot of wood, still in a carton stuck somewhere between Champaign IL and here for the last couple days...

Stringers on (3/16" square), and started on the first course of planking.

The planking sheets were all epoxied one side, sanded, and ripped into 3/4" planks... 12 sheets to do the first course, 12 more for the second, and a bunch more on deck later.

It looks more like a chopper to cut the angles on the planks since each one is cut differently.

Chopper.
Has sticky back magnet sheets, so's I can lay down a steel rule to use as a fence.
