Handmade Harnesses for Aircraft?

Tea bags? Interesting, in 1/72 I do the white glue thing with the high quality tissue paper that shirts and ties are wrapped in.

I can't speak to those specific aircraft. The standard seat belt for many years in US military aircraft was about three inches wide, with shoulder harnesses about two inches wide or a little less. Divide that by 1/72, 1/48 or 1/32. For example shoulder harnesses in 1/32 would be 1/16 inch wide.

The Spitfire had something called a Sutton harness, which was four equal width straps about 1 1/2 to 2 inches wide with multiple holes in them. See http://folk.uio.no/hungnes/avia/spitfire/Sutton.html

The Russians reportedly used the Sutton harness as well.

There were other variations. Pre WWII US Navy aircraft didn't have shoulder harnesses. They finally figured out that padding the gunsights wasn't an adequate substitute...

Measured an Eduard PE set, & the shoulder harness for the Yak is 1/32" & the lap belts are 1/16".

Since the models are to scale, if you know the width of the actual harness you can cut the material to the proper width. If the strap is, for example, 3" wide in real life then your 1/32 scale strap would be 3/32" wide. For the 1/48 scale model it would be 3/48" wide (3" divided by 48 scale) or 0.0625" or 1/16" wide.

Model Technologies (oop).......Re-Heat, Waldron & it seems now, Velinden that i know of, (not sure about Eduard) all produce PE seat belt buckles in 1/48 & 1/32.........
utilizing these devices along with whatever belt replications of your choosing, wouldn't the (in most cases) belt material be proportional in width to the buckle size ?.........length and configuration would be proportional and in accordance with what reference photos you're also using........
just more........
for me PE seatbelt assy's just don't have the texture or positionability of homemade front office restraining apparatus(es).........
