Robbe PT15 cabin and bridge..from scratch...
Hi everybody. Y’all remember the “fun” I had about 2 months ago, with the SAR motor issue and the loss of the PT15’s cabin and bridge? Well, I’ve got the SAR fixed, retrofitted a 3530 1700 kv outrunner and a much better coupling, and she runs smooth and cool. So...I decided to go ahead and do some updates and maintenance to my other boats in the fleet, which led me to the PT..I decided to start building the superstructure and get her back in the water. I worked too hard on her to let her sit around and gather dust.
I bought a pack of styrene sheet in various thicknesses, and ordered some sundry items that will be needed from Cornwall Model Boats. While I’m waiting for those I decided to start cutting plastic.
Now, the original structure was comprised of 2 main moldings, some detail moldings, and of course built up detail parts and fittings. All that is at the bottom of the lake, and this boat is way the heck out of production, so I had no choice but to build it up from sheet. Luckily I kept my plans. I traces what I needed to get started from the plans and cut templates. Then I cut my sides and tops.i built the main cabin first. I’m using balsa stock at the joints to allow me to sand a decent radius in the finished cabin(s) as the original had a slight radius at most corners. I also had to build up the entry “buckets” as they were molded parts too.
I got the main cabin built last night, and the sub/aft cabin tonight. I think it looks okay for now, need to finish some sanding and then join the two halves together with a bulkhead and ramps as the original. Still have to do the bridge, the original bridge was molded with the lower main cabin as a unit, and that entire section was molded from tinted clear plastic, you masked off the windows and shot it with paint. I’m going to have to build the bridge as a separate part and glue it on. If I decide to do clear windows, I’ll have to cut the openings, paint the cabin and then glaze the windows before gluing it on, then mask the openings when I paint the final assembly, as I’ll have no access to the inside of the bridge once it’s glued in place. Alternatively, I can just paint the whole thing and paint the windows as they were pretty dark to begin with. I’ll make that decision in a few days, but I’m leaning towards glazed windows as I think it’ll be worth the effort.
Take a look tell me what y’all think, this is my first time scratch building anything in plastic.
