Homemade Saturn V Stringers?

Hi,
Currently involved in a Saturn V build. Body tube size is too small for vacform stringer wraps like from Apogee. Any suggestions on how to make some nice looking stringers? I was thinking maybe some Evergreen styrene channel or similar but wanted to see if anyone else had any thoughts.

Thanks

On John Brohm's Space Transporter America build he used styrene sheet and flat strips. Or you can use plastic half rounds of the appropriate size.

I would say it came out very nice!. Cheers.

Wow! I would have to say it came out very nice as well. Styrene strip probably will be the move, I don't think I'll be able to find round small enough. Thanks for the help.

I made stringers for a model using cardstock...the build thread is here https://www.rocketryforum.com/threads/build-thread-jupiter-120-direct-2-0.114568/

If by "very nice" you mean "one of the finest quality builds I've ever seen" then I would agree!

1:1 scale is always the best.

There is no substitute for the "real thing" . . . LOL !

These are the dimensions of the full size Saturn V stringers:

Outboard engine fairings on S-IC: 19 1" x 1" L-section stringers, equally spaced.
Aft section S-IC: 128 3" x 3" hat section stringers, equally spaced. There are a few odd-sized hat section stringers near the hold-down post areas, need to double-check dimensions.
S-IC intertank: 108 equally spaced corrugations, made from 18 full length panels
S-IC forward/interstage/S-II aft: 216 2" x 2" hat section stringers, equally spaced
S-II forward: 144 1.3 x 1.625 x 131.42 hat section stringers interspaced with 1.00 sq. x 88.50 I-beam longerons; bottom section of stringers buried in LH2 tank insulation.
S-II/S-IVB interstage: 144 1.2 x 2.162 hat channel stringers, equally spaced
S-IVB-500 aft: 144 x 1.375 hat channel stringers, equally spaced
S-IVB-500 forward: 108 .813 x 1.25 hat channel stringers, equally spaced

Source: David Weeks Saturn V drawings.

Note that any fairings, etc. are not included in the total stringer count.

Stringer count on S-IVB-200 aft: 112 1.00 x 1.375 stringers, equally spaced. Forward section same as S-IVB-500. S-IVB-200 is for the Saturn IB and the mockup S-IVB used on AS-500F.

I've been searching for a link to the Weeks drawings for some time and can't find 1. Anyone know where I can get them?
