I bought some of that stuff from a scrapbooking store in northern Indiana last year. VERY nice stuff! If Michael's isn't carrying it anymore, check online with scrapbooking vendors-- I'm sure SOMEONE will have it.
My SIL gave me her old 'corrugating' machine from her scrapbooking stuff... it's like two gears about 9 inches long that mesh and corrugate the cardstock as you crank it through by folding it between the gear teeth. Only problem is the corrugations are almost the size of those found inside cardboard box-- WAY too big for rocket corrugations unless it's huge, in which case you'd use something else anyway to get them square edged... I've been thinking about making a chingaderra to "roll my own" by meshing to pieces of all-thread rod together, using all-thread with the proper thread count/pitch corresponding to the desired corrugation spacing, and meshing the two rods together with the tips of the threads on one rod meshing into the troughs of the threads on the other rod... for small rod it would require some kind of 'backing rods' to support them in the middle and prevent them from 'bowing apart'. Sorta like this:
0 0
0
--------------- sheet of paper
0
0 0
VVVVVVVVVV
------------- sheet of paper
VVVVVVVVVV
It would put the 'corrugations' lengthwise on the paper and at a slight angle corresponding to the thread pitch, but you could cut the corrugations out square once you were done. I suppose one could make a similar machine that would make the corrugations square by getting a bunch of R/C car/truck gears and meshing them together on a pair of shafts, using small gear teeth to get the correct corrugation size, similar to the scrapbooking paper corrugator.
I've also heard of folks using a paper 'scriber' to make the corrugations individually, but that takes FOREVER and requires VERY careful work to keep them evenly spaced and parallel, and if you goof up you've probably ruined the wrap.
Apogee Components sells 'generic' wraps vacu-formed in thin white plastic... I've bought some for my 1/100 Ares I and they look pretty good. They were like $7 or so for the set for two sets on a sheet-- one 'close spaced' fine corrugations and one 'coarse set'
Hope that helps! OL JR
