Thats the one! I use a Brummell lock splice on all my loops and have never had any issues with it yet (Rocket and camping). That specific link you posted is mainly if you're not able to pass the tail end though. Still good, but you have to take the extra step of taking the twist out. Here is...

Thanks! I have yet to find something that I liked for a minimum diameter, but so far this seams to work even under a bit of load.

Work, life, other projects (mainly a wireless launch controller) have kept progress slow here, but recently did a few things. Figured out how I want to attach the recovery harness to the rockets. The motor retention bolt will have a washer & spacer. The kevlar will be in a printed circular...

Yes, I tried a regular 22LR, but it was just too short. The .22 mag was just about perfect. Here was my set up. https://www.rocketryforum.com/threads/with-a-little-help-from-my-friends-2-stage-54mm-min-diameter.165955/#post-2343825 Only difference now is that I also use a small amount of sticky...

The clubs I go to have the Wilson systems and they are awesome, but too expensive for at home. I have been doing some ignitor and ejection testing and got tired of my old system that had a 30ft cord I had to roll out every time. A few weeks ago, I bought some parts and started designing a...

The Featherweight system is $365. Myself and others highly recommend it.

It has taken me a while to get back to this, but I have done a bit more testing for the ejection for the fun of it. All sticking with 1g of BP, but using 2 different tube sized (ID 5/16" & 9mm) and 3 different lengths (1.5", 2.5", & 3.25"). Each tube is made the below way: - 3d printed bottom...

Hey Travis, welcome to the forum! Seams like your going about launching your self with building controller which is cool. If you're ever interested in joining a local launch there are several groups in the area. DARS is probably your closest. If you're willing to drive 2-3hr there are several...

Not a new member, but some how never commented on this one. Way back when in HS when I got started in rocketry, I spend most of my time playing tennis and my screen name was tennisace. So starting out in rocketry Rocketace just seamed right.

Here is another example with no issues.

Besides the ones you have listed, here are a few more considerations that need to be mostly sorted out in the design / test rocket phase. - Electronics, what will do what and how will they be programmed. - Same but with the back up electronics. - Arming safety - Getting a straight flight -...

1) Complete, test fly, and fully fly my 54mm minimum 2-stage diameter rocket 2) Finish designing and start building my 16" FatBoy 3) Continue helping out a local university at the Spaceport America Cup 4) Attend more launches with awesome rocket people! 5) BALLS.....?

Simple, affordable, and reliable. It's hard to beat the PF line that you can adjust main deploy settings on the unit without a computer and for most flyers having the extra terminal block to make connecting wires simple is worth the space. My first altimeter was a PF MAWD and a few years later...

US composites for all the cheap, quick, or good enough jobs. Rocketpoxy and 820(from sollar composites) for the rest. Then for the odds and ends….JB weld, Gorilla glue, GearAid, Titebond, Loctite, BobSmith…and the list goes on. They all have their uses.

Yes the Quark is small, but it requires at least 6V and is designed for a 2s LiPo. Nothing against Eggtimer (I use them reliably and love building them), but for some applications I prefer altimeters that use 1s LiPos.

This one is pretty nifty and small. Smallest dual deploy I could find. Only 2 downsides is that it has no recording, and from one of my flights I do not think it's Mach immune. So if you don't need data and not going Mach, I would highly recommend this little guy. It does come from over seas but...

4F powder and the lighter was at the to of the powder. . Instead of an ematch its old match leads with some nichrome wire to keep testing cheap. Tube is 5/16" ID x 7/16" OD x 1.8" Long. 0.6" of dog barf on the bottom and 0.6" dog barf on top. I plan to do a few tests with various changes to see...

Oh and I built some hot boxes! First is a small box that is big enough to fit the fin can section of the rocket. The tube will have to stick out. But, I also heavy insulated the inside to I can also use it to anneal 3D printed plastic parts and not melt the styrofoam. Uses a variable settings...

Another month down and not as much progress as I hopped, but still progress! For the ISC, there will be 3 tubes. The left one is the exterior coupler (still needs to be cut to size) and the right is the regular tube coupler that I sanded down with the drill above. The center is a section of FG...

Here is a few pages from my L3 paperwork. A all custom built 8" rocket from concrete forming tube, 1/2" plywood, and foam sheet. All the structural parts were less than $100 (does not include electronic, recovery, or motor). I was a broke college student. If I were to do it again, I would spend...
