Warren, I’m surprised the club would let you use them on their rail. I thought most clubs prohibited the use of metal rail button because it galls the rails. I guess most people figure its easier to replace the rail…   Read more»

Whaddya mean L3’s only use 1/4-20’s?. Two 10-24 stainless screws should be able to easily hold 300# before deformation. I used to have a table around here somewhere and the individual screw needs over 300# before deformation begins for even…   Read more»

Gotcha… I wouldn’t use those beauties on a 1010 rail. L3’s only use 1/4-20’s. I can wait.

Not for the 1515 style buttons – the shaft diameter precludes it.I’m thinking of making some Unistrut buttons somewhere down the road and those would take a 1/4-20 flathead screw. I’ve also got a program written to do 1010 sized…   Read more»

Warren, those look fantastic! Any chance of getting a hole to fit a 1/4-20 bolt? Your prices are more than reasonable! Very nice!

Congratulations! As far as getting things going with Colorado Research Supply; you take care of yourself first, always!Art

Sorry to hear this Conway – hope everything works out on the health front. The business can wait, though it’s fantastic that you’ve finally got you paper and can start storing propellant. Congratulations on that.Warren

Kevlar is a total pain in the ass. I have two pairs of supposed “Kevlar shears” I bought at Hobbytown sometime back and even they hack the hell out of it. A clean cut is essentially impossible.if you take a…   Read more»

You guys are the gurus. Warren, you’ll get a kick out of this, I’ve put the CF/Kevlar hybrid on and will use a Mikita hand disk sander to get rid of the excess and frayed parts tomorrow. Oh, that’ll be…   Read more»

What I’m getting at is that we seem to be overdoing it, me included.JW, you may be correct, but are any of us willing to take the chance? I will say that a piston strap broke and a ~30# booster…   Read more»

John, your booster and the spent casing that fell from 23K was maybe 4# or 5# if I recall correctly. My best estimate for weight for this booster is about 25# with the casing. Conways bird (whole bird or just…   Read more»

http://www.wicksaircraft.com/catalog/product_cat.php/subid=489/index.html is a good source of Aeropoxy, though I don’t see the “Light” (which is a wonderful filler) there. For that, I went to http://www.aeropoxy.comRegarding using kevlar and carbon and mixing and v-bagging, I’ll say this… I had a booster…   Read more»

Sounds like we reached the same conclusions Conway. The way I built it up was I took the fin blanks and laid 4 layers of glass from the root out 1/8, 1/6, 1/5, 1/4 on each side and v-bagged that…   Read more»

Warren. Your Fin Can sounds like how I did Full Throttles fin can for my L3. The resonance issue is attributed not to just placement but the types of materials used. Two different materials is always better then one similar…   Read more»

Warren, you’ll do very well. No one doubts that. You are one of our composite gurus. I believe, as you do, that it’s better to over-build than under build. I’m using CF/Kevlar hybrid on my motor mount, first layer glass,…   Read more»

Through the wall. This is killer bombproof, mainly because I’m building for N motors and also because if the thing comes in on an apogee streamer without the main deploying, I’d rather be able to fly it again rather than…   Read more»

Warren, I’ll trace out a template of what I need. I’m going to go tip to tip x 2 for my 98mm minimum diameter project. I will fly it at BALLS ’09. I figure by doing the layup this summer…   Read more»
