I watched it just the other day and paid attention and still can't get a couple of the answers... Warren

It is possible to get good enough at doing rocketry that your rockets wear out rather than are lost or destroyed. Really it is... eventually I may actually figure it out myself. Knowing exactly how yo...

For that size rocket you almost certainly want to use buttons for 1010 rail and I wouldn't consider going larger until I passed 25 or 30 pounds or so and even then it's probably overkill until you hit...

Never. You will also find folks who use a single charge with dual matches in situations with redundant altimeters. You better damn sure know your charge is sized to be absolutely reliable about kickin...

Ya gotta love machine shop tools. I have access to one, but have never used it for G10 tubing. A definite improvement over the cutoff wheel - the slow speed keeps the dust down. Warren

In practice, you'll find that it's pretty difficult to get two barometric altimeters to fire at the same time. Aside from sensor tolerances, altimeters like the RRC2 family just don't have the resolut...

hard to predict and depends on the foam, how carefully mixed, how much space to expand. Weigh the liquid before you mix it, mix and pour. You can figure the density by figuring the total weight divide...

I use a 10" chop saw with a cut-off wheel and then dress the cut edge with my benchtop disk sander. After that I go over the cut edge by hand with some 220 wet/dry paper under water. Wear a breathing ...

On smaller birds I use the round stock that John Wilke mentions in his post. On 3" and 4" birds I use 2-56 nylon screws although if the nose is heavier I've been known to go up to 4-40. I always use t...

Great pics Bruce...! Warren

That wasn't our doing that he wasn't there for Oktoberfest. Guess they didn't make enough money at MHM due to the rain out. The things that require the vote are NCR Club President. For Tripoli Members...

Although I do build a kit from time to time, 90% of what I do is scratchbuilt. Given the amount of work involved, it makes sense to buy what you can and only make what you have to. Oh yeah, this threa...

Afraid I'm going to have to pass on the Parrot until after the Christmas season or further on. Grandkids and kids gotta come first right now. Also, if you're going to do another altimeter - whether ba...

I'll agree, not many do what we do and most end up with a layer or two of glass soaked with about 5 times the necessary amount of epoxy or glass fabric poorly bonded to the tube because they didn't us...

I live by peel-ply. I almost NEVER use mylar. I would rather have the textured, bondable surface and minimal epoxy that results from using peel-ply than a mirror smooth (hard to achieve) mylar surface...
