This Frenzy Massive's sorta tall...


I resumed building today, completed the following, and everything's curing in my warm garage:

Frenzy Massive:
  • Designed the EBay sled template in Illustrator, traced and cut that from 1/16" G10, JBWelded brass tubing on the bottom, taped the tubes in place, and threaded into the cavity to cure in line with the 5/32" all-threads.
  • Scuffed up the motor tube, marked the positions of the centering rings, and epoxied all three in place.  I should note that I'm not leaving the aft-most ring free as recommended in the instructions.  I'm confident that my fin mounting methods, in combination with expanding foam, will withstand even a CTI N10000.
Extreme DarkStar [Heavy]:
  • Numbered, sanded, and fit fins into booster slots
  • Inspired by Darrel Kelley's work I cut a comb-like pattern into the fin roots to improve adhesion to the motor tube:
  • Scuffed up all fin tabs
  • Epoxied first pair of fins in place (make that two pair)

30lbs empty, 60lbs with the N1975 installed.

I think you may be underestimating...

And don't you mean "wood" add?

Well that would add 4.14 pounds.
