In between tinkering with the wings I've been pondering how to do the dreaded stripes on the prop spinners. This is what I came up with. I'm sure it must have been done this way before?
1) prime and spray white acrylic:
2) use narrow bits of Tamiya tape of same length to make a "bridge" between the back of the spinner and where the stripe needs to be:
3) using the end of the "bridge" as a guide, use a 1mm wide strip of tape to mask the stripe. Using straight tape got me nowhere, I experimented with using lots of bits of straight tape end to end but eventually used a curved strip. The amount of curve was pure guesswork and I cut it freehand, it just made it easier to cope with it going round the curve of the spinner. It was fairly easy to smoosh it around with my thumbnail until it looked something like a circle, then I could burnish it down.
4) remove "bridge"
5) another squirt of white to seal the edge of the tape:
6) couple of layers of roundel blue:
7) after drying, remove mask:
Stripes!
It's not 100% perfect close up like this but to the naked eye at 1/72 looks decent. Fairly pleased with this outcome. Should look better with a bit of satin varnish on it.
