Well doggone it! Even the simplest things aren’t so simple. The C channel for the main frame rails on the bomb trailers are 5 inches high. That works out to .06944 in 1/72 scale - essentially .07 inches. Evergreen does not offer .070 channel. Only .060 and .080. I know the difference of .01 inches seems insignificant - and it is - at any other scale. But in 1/72 it’s nearly 3/4 inch on a 5 inch component. That’s a greater percentage of error than putting 1/32 items next to 1/35!
So I thought I could make it from .050 strip with flanges made from .010 x .020 strip - .050 + .010 + .010 = .070. Perfect! Except that once again, Evergreen do not produce .050 strip.
Soooo…
I’ve take .060 angle and cut down one leg of it to resemble an L. Thankfully I only need six pieces, all just over 2 inches long. Now I just top that off with a .010 x .020 flange and voila - a .070 channel.
Of course, if there are any irregularities in my cutting (there won’t be - I know myself by now) the trimmed piece of channel would be on the underside of the frame rail where it would hardly be seen, if at all.
