October Meeting Minutes (10/3/2008)

The October 2008 MASA meeting was held on the 2nd at the Science Museum.

A total of 4 people attended the meeting.  (Where was everybody!!!)

Next Launch: The next regular launch will be on Saturday, October 25 at the sod fields near Nowthen.  This will likely be the final launch of the year at the sod fields.  Theme of the launch is "goonies and odd-rocs".

Next Meeting:  The next club meeting will be on Thursday, November 6 at 7pm at the Science Museum.  Major order of business is opening nominations for 2009 MASA officers.  A topic or activity is needed for this meeting!

Other stuff:

  • NIRA is hosting a sanctioned regional competition in the Chicago area this Sunday, October 5.
  • It's time to get thinking about the club holiday party (where, and when?)
  • TARC registration is now open.  TARC mentors - "on your marks, get set, GO!"
  • S/T Rick Vatsaas reported that MASA currently has 26 family memberships, 15 senior memberships, and 2 junior members.  There is about $500 in the treasury.

Show and tell:

  • Andy Heren brought a vintage package of Centuri B6-6 motors that were given to him recently.
  • Rick Vatsaas brought two of his "cup rockets".  The bodies are made from cups purchased at "Bed, Bath and Beyond."  [Wow, that "beyond" section really does have everything!]  One is complete and has flown; the other is still under construction.  Rick also brought his scratchbuilt 4" diameter "Rather Big Bertha".  He plans to fly it on a J350.
  • Alan Estenson brought his Estes Big Daddy with custom "Der Grosser Vati" decals.

"Making Composite Fins for low, mid, and High Power rockets" by Rick Vatsaas

For the evening's topic, Rick presented some ideas and methods for making composite fins.  He talked about fiberglass, epoxy, molds, and vacuum bagging of small fins.  Rick shared some ideas for doing vacuum bagging inexpensively.  He uses "ziploc" type bags that can be evacuated using a small electric or manual vacuum pump.  Instead of peel-ply, he uses ripstop nylon.  Rick demonstrated by mixing up some epoxy and vacuum-bagging a balsa fin right on the spot.

Thanks Rick!
