| Regarding stretching sprue: this first subject I wrote to Scale Model Forum about! Getting stretched sprue fine enough for 1/72 is hard. I have tried it and used it on the Bf109 and Hellcat in my gallery pics. As you can see in the Bf109 it's way out of scale, but not so bad on the Hellcat. I switched to using "invisble thread", fine monofilament used in dress-making. It's probably still too thick for 1/72, but it is looks OK to my untrained eye. By the way, if you stretch the sprue thin enough and hold it while it cools down, the bit in the centre should be fine and straight enough to use.
Regarding weighted wheels: Maybe I'm not fussy enough, but I just sand them flat on the bottom. I reckon your heated method is better - try it on some spares ones. |
