Never tried making bezels at 1:96 scale, thought about ringols but have not actually fitted any. I find the problem with 1:96 scale is that small things tend to look larger than scale when fitted. I am on my second 1:96 destroyer and my port holes are just holes made using drills (starting with a very fine one then slowly working up to a 3mm drill).My big problem is glazing. Deans Marine suggest either a sheet of clear plastic behind them or using 2 part Epoxy such as Devcon used to bridge the hole applied with the hull on its side. The first suggestion is OK but no good for the highest levels of port holes which can be at the same same level as the balsa wood deck supports. The second suggestion is OK but I find it only works for a certain level of glue viscosity after which the technique does not work so the holes can only be bridged in smallish batches. Anybody got any thoughts on this?
