Default Tubular and Ring Fins (Semroc)

Last week, I wrote (off-line):

< Still need to glue together 8 really short pieces of ST-5 tube to see how tightly they'll fit around an ST-8... and then I need to see about that 1" long piece of ST-20. The launch lug might be a PITA if I don't "Grip it and rip it...">

Here's my experiment. The eight ST-5's fit *very* tightly around the ST-8, so it looks like I'll have to use the standard Groove Tube "glue by pairs" technique, not to mention securing them with an elastic shock cord while they dry. A 1" long launch lug will fit nicely between the ST-20 and a "notch" between two ST-5's.
