The latest thing I've seen is to use 1/4" diameter surgical tubing. Put your e-match in one end and secure it with a tie wrap, put the amount of powder you need in and secure the other end the same w...

(I kind of found it weird that West Sytems was clear!) I use the 125/229 combo and sometimes the extra long working time 237 hardner, pot life 6 hours! (requires post cure). I use the thin resin and...

I do vacuum bagging but I prefer Pro-Set epoxies. Its made from the same company as West Systems but it has a variety of different resins with different viscocities as well as the different hardners....

I think that NAR rules says something about live payloads being vertebra... Doug

Sorry John, I won't be there for the July launch or you could use mine. If you're willing to wait until Oktoberfest... Doug

Try using CA where you want to cut it. Let it completely cure then use wire cutters. Doug

pistons work well too... Doug

constevens, do you do mail order? I've been using House of Kolor paints and just getting them on line. Doug

I don't know Warren, we spend how many hundreds of dollars building and flying rockets? A couple of extra bucks to make the job easier sounds reasonable to me. Doug

Another material I have used besides cardboard is foam board. You can get it 20" x 30" in many arts and craft stores and sometimes as large as 30" x 40" in office supply stores. It is very rigid. I...

If you, or anyone, is interested I'll offer one of my cameras to go in your rocket. (They love a free ride...). If you want the high speed movie camera or stills, but I don't do video or even DV. I...

Sounds very nice Warren, but which camera are you going to use in your payload? 😉 Doug
