I’d like to hear if there has been some kind of rule change. I’ve frequently gone to the north site and other nearby places in the grasslands to sight-in my rifles and do a little plinking over the last 4…   Read more»

Actually, there may be some new USFS regs which may preclude use of firearms at the N. site. I’ll check into it, I have a great source there. I was quite surprised when I heard this, but the person who…   Read more»

Do be aware that we fly on federal land – the National Forest Service administers it. The rules are quite different. Firearms are explicitly allowed to be used anywhere on the grasslands subject to the state restriction of not within…   Read more»

Doug,You make two really great points here. One, we REALLY need to be good citizens with the land use agencies. Particularly as our launches get bigger. Joe does a fantastic job with this on behalf of the club but we…   Read more»

I used the red plastic one and it seemed to be OK, I think there is a blue one and a green one, the green one seems to be a lot more plyable. I think it really depends on your…   Read more»

Scottethere are also different types of peal ply, so something I have learned is do not use the cloth and the pink. I have documented some of the steps in laminating, send me a pm and I can share with…   Read more»

You really need to get peel-ply from a composites vendor such as Fiberglast.com or Mr. Fiberglass. Aside from the fabric material itself, peel-ply is typically coated or impregnated with chemicals to assist with it’s resistance to epoxy bonding. Plain old…   Read more»

Peel-Ply is a dacron fabric. Remember that white nylon like fabric I showed you? It’s used to create a rough surface so subsequent layers can adhere better. It’s porous and allows the epoxy to soak through. When the epoxy is…   Read more»

WellFinished 2 layers of glass on every thing. Boosters almoast 5 pounds!I figure the whole thing will be about 10 lbs before Motor. Is that aboutRight? THe Quantum leap sustainer was just over 6.

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…   Read more»

Here I was thinking it was Taboo to buy them tubes premade!Must be my initiation into the club. 🙂

Doug, you have a PM.Ken.

YAHOOOOOO

Rocketry is all about choices; phenolic or glass? Motor ejection vs. electronics? Aerotech vs. Cesaroni? Hybrids vs. AP? Rails vs. lugs? Lugs vs. towers? Painted or primed? Three fins or four? Conical vs. ogive???? Missile Works vs. PerfectFlite? Davey’s vs….   Read more»

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. I fill the texture with epoxy…   Read more»

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…   Read more»
