Portholes
Among the deck details are the portholes in the forward cabin. These are essentially black plastic flanges and are the same fittings used for the hawsepipe. There is one to mount on the port and starboard sides of the cabin. Mounting these requires cutting holes in the plastic cabin.
Since the flanges have no “glass”, I used some clear plastic I bought a long time ago from the manufacturer Plastruct, which makes all sorts of plastic shapes for architectural and craft projects. Hobby shops used to carry this stuff all the time, but those stores are becoming few in number. You can order direct from Plastruct if you need to, or in this case, you can cut a small piece from a clear acetate sheet protector, which you can get easily at Staples office supply.
The plastic just needs to be big enough to glue over the inside end of the porthole. If you glue the piece into place first, after the glue dries, you can then trim off as much excess as you can, to make it easiest to put the porthole into the hole you’ve made for it.
For glue, I used a product called Canopy Glue. This stuff dries fast and clear. Other glues, like CA or plastic cement, often mar or fog the clear plastic. This is another one of those things I picked up from the hobby shop. The item is specifically called “Formula 560” which comes in a 2 oz. bottle from a company called Pacer.
The portholes come pre-molded in black. They looked pretty good, so I didn’t bother to paint them.
