Hey all. Wondering if I could get some help with a hopefully quick question. Is anyone able to measure the ID of the Apogee PNC-2.14 nosecone shoulder? I'm planning on 3d printing a bulkhead / electronics sled to fit up in there and want to get the dimension right. However, I don't want to...

I'd like to mount some electronics in a 38mm "thin-wall" polycarbonate nosecone and am looking for options. Right now my main priority is less on getting a working electronics set in, and more about setting up a recovery harness anchor that won't preclude them in the future (i.e. epoxying on a...

Over the weekend when I tried loading up TRF, I got an Amazon Web Services apache test page. Monday and Tuesday, the site loaded nothing at all. Did this happen to anyone else? If it was down for everyone, what was going on?

Here's a basic question: when painting largish to large rockets, how do you keep them stable for painting? With the model ones, I've taped a dowel to their inside and used that as a handle or stake from a cardboard box. However, with bigger rockets now (current one is ~500 grams) that seems...

What about metal reload casings? It seems definitely possible that those could be considered "substantial". Since FAA Class 1 doesn't require a waiver, the intended goal seems to be "if a plane hits the rocket, the plane should be", and I'd think that a metal casing has significant potential to...

I have an Dr Rocket single-piece 38mm aft closure and adapter for a 54mmt. This thing screws on as an aft closure for 38mm casings, but is flared out to fit a 54mm motor tube and motor retention. Apologies for dust in the photo I'll add a lasercut plywood front centering ring assembly...

I figured out a workflow that sensibly lets me post camera images from my work computer, so here we go. Lot of time without support calls, especially weekends... Ingredients: One 4ft 54mm piece of Blue Tube, one plastic 54mm nosecone, plywood, 38mm MMT, assorted other hardware. This...

This may be a tad rambly. I deal with chronic depression. It never really goes away, even with treatment -- some day, weeks or months are better, some are worse. During the good periods I can be reasonably productive, competent... able to set my mind to a project and get it done, able to...

At the launch yesterday, I did something pretty stupid. While assembling an AT G64W-7 load, I dropped the grain liner in the dirt... then immediately stepped on it. The liner is trashed. However, I immediately re-bagged the other components, including the fresh propellant grains. I'd...

What do your rockets land on? You can vote for multiple options in the poll above. For a given surface and rocket construction type (lightweight paper, cardboard&plywood, composites, etc) what kind of descent rate do you find is safe? My primary field is scrub desert... the surface isn't...

Anyone here assembled a rocket, done the finishing work, then decided you're just not happy with it? Over the summer one LPR kit of mine... just didn't come out as well as I'd like. Things started badly when I didn't check the instructions and glued the nearly-symmetrical fins on...

A friend of mine has dabbled in rocketry before, but isn't currently active in the hobby. They gave me five Estes Hi-Flier kits that had been sitting in a drawer. Now, though it's definitely an awesome rocket, I don't need five more of those in my fleet. Maybe, another two. So what to do with...

Ever wanna ask a question, but think it's too minor to bother starting a new thread over? Well, I know I do, all the time. So let's go ahead and have a miscellaneous Q&A megathread! Ask away! ---- Here's mine: anyone have experience with Giant Leap single-piece chutes? How do they compare to...

It's time for me to fly avionics, and I could use some advice. Right now I have a RRC2+, and the testbed will be a Wildman Super Jart. In general I like the idea of stashing my avionics in the nosecone; single-break w/ cable-cutter for DD seems more elegant to me. After reading a bit, it...

So, I'm using a mix of Future and Simple Green to clearcoat my rockets. Lately I've noticed that rather than forming a solid sheen, I get a speckle-y orangepeel texture. It seems like the stuff from the spray bottle is mostly sliding right off the rocket rather than adhering and curing. Do I...

I don't like mass, and I don't like complexity. So here's something my brain came up with during a slow friday at work: 1) Create a small, strong casing for your avionics and battery of choice. 3D printing is a good candidate for this. For wires, use either pass-through pin headers or...

Vinyl, it's good for more than just sticking on rockets! Here's what I just put on my ride (1999 Jeep Cherokee) There's also their logo on my range box. What have you stickershocked?

So at our club launch yesterday, someone (Todd Kerns) loaded up their Wildman Space Cowboy with an AT J1299N. Our self-appointed club photographer, Jim Jewell, was taking pictures of every launch that day, using a 4-per-second burst mode. I bet that there was no way that was enough to get a...

Epoxy can be kinda nasty stuff. Getting it on the skin is definitely not good for you, plus it just feels icky. In parts or mixed, it sticks to any surface it comes into contact with, and can be hard to remove from unwanted places. Epoxy is also a key adhesive for rocketry. So, here's how I do...

Discussion in a certain thread from The Watering Hole prompted me to post this. My plan here is to post, as objectively as I can, an account of a recent order I tried to place with Red Arrow Hobbies. Mostly this will be via unedited email logs (though I have redacted my meatspace name and the...
