AvPro Marauder (1/72)

Nice start. My brother is a retired shipwright and would be very impressed with that hull

Looks like the sort of 'in build' pics I see in Model Boats magazine.

Well, it is the flying boat group build, I just wanted to make sure I had the boat part covered

Frame filled in with apoxy sculpt and much sanding later.

Unfortunately it's really lumpy.  I knew I shouldn't sand all the way down to the styrene ribs but I did it anyway  I think I need to coat the whole thing with a thin layer of apoxy sculpt and then sand again.

Here's the bottom before filling in with apoxy sculpt.

Good job!

I like to work my Apoxie Sculpt before it hardens, using water & whatever tool I find appropriate for the job at hand. In the case of your hull I'd probably use a wet block of wood, used like a sanding block, to get the basic shape before it cures. Once cured I'd wet-&-dry it to get the final shape. Occasional fixes often involve using something different, like Tamiya white putty.

Yeah, that's pretty much exactly what I do as well, although I use the Aves solvent instead of water to smooth everything out.  I also have a couple other sculpting tools I use as well.  The ribs mess with things a bit.  One, I want them completely covered so it's hard to determine just how think the material is over the ribs, two when smoothing the ribs mess with the flow of the apoxie sculpt so there are faint ridges as the material builds up behind the ribs.

Instead of scrap styrene, how about xps foam styrene, the kind you get for insulation at hardware stores?  You can cut, carve and sand it to shape, then use the Apoxy sculpt over the top and you shouldn't get as much lumpiness?

One sheet won't cost much and would probably last years.

Having faired full size boats, new-build and repaired wooden boats, and fibreglass boats - hull repairs,
I recommend using a batten to check the surface as you sand, also a long-skinny fairing block is better
than a square or low aspect ratio rectangular block.

Not a whole lot of progress to show.  Here's the frame for the engine nacelles.







This has since been filled with apoxie sculpt and received some PSR.  I'm going to build one nacelle and then vacuform two copies, mostly because I've lazy.  The top and bottom bucks/molds are close to finished, just doing some fine tuning.

Love watching this level of engineering in models

Thanks gents!

Work continues, here is the bottom portion.  I tried to make it a little more boat like than my references show.



Here's the engine nacelle.  Slightly more stealthy than some of the artwork of the Marauder.



While I'm sure neither of these pieces are completely symmetrical, I'm calling them good enough.

They'd look good in an article on high speed model boat hulls!

Symmetry is over-rated.  Just ask Tophe.

This one is what made me fall in love with the Marauder. I want one so bad, but not bad enough to do what you're doing!

Nearly all the artwork I've seen of the Marauder is different. I don't believe it was a concrete proposal.

Spot on. I don't think they ever built a single aircraft (of any type they proposed, not just the Marauder) or even a mockup.
