Primed and sanded (mostly). Waiting for the Nosecone to show up, and decide if I want to use a “flush mount” engine retainer, or wait for the screw-on ones to become available again. Also need more primer if I decide I really want to make it smooth.

Help Support The Rocketry Forum:
Looks like an...excessively stable...rocket. I have one with almost exactly the same outline except that it's built around a BT-50 (24 mm). Launch should probably be in zero wind.
I am considering doing my certification launch in the "half size" configuration. My only hesitation with that is that it will (obviously) go much higher and I see so many recommendations suggesting avoiding that for a cert flight. To be fair, I'm a long way away from that since I need to actually joing NAR or Tripoli, and probably attend a launch or two to see how everything operates and meet people and get people on-board with certifying me, yada yada.
On a personal note, the entire "meeting/socializing with strangers" is the most difficult hurdle for me to overcome. I have irrational levels of anxiety about showing up to events full of people I don't know...hell even events full of people I DO know. Posting on this forum is a first step for me to start to feel somewhat comfortable with the community. But, in the mean-time, i'm just working on my rockets.
I wouldn't worry too much about flying out of sight. Either fly a tracker, or else hang around enough launches to get comfortable with what size and altitude of rocket you can keep in sight and act accordingly. (But really, fly a tracker.)
Re. meeting/socializing with strangers, I'm right there with you. I am shy to a fault, and getting to my first club launch was a major step out of my comfort zone. I will give you this encouragement: I've never met as friendly and helpful people as I have in rocketry, which is good, because in my two years back in rocketry, I've met more people in less time that at any other time of my life. Swallow your anxiety, make yourself take that first step, and you'll be rewarded.
I am sending an email to eggtimer tomorrow…

What is that bar for?
It look like an anchor point, or to strengthen the part

Wouldn't use it for an anchor point. The print is weakest along the print lines
It's intended as an anchor point, but I probably won't use it for that because.... :
Well...actually I just wasn't going to use it for that because I'm not familiar with 3D prints and my spidey-sense didn't trust it.
Busy weeks, but a bit of progress. Epoxied the Nosecone, sanded, primed, sanded, painted, sanded re-painted.
I got most of the paint done on the main rocket. (Having given up on having a smooth finish).
Still waiting to purchase engine retainer, and recovery gear. Also need to install the baffle (but I’m still debating how I want to do it since it’s a bit too small for my tube).

That boy tallllll!
I can't wait to see if fly
I plan to use “military style” stencils to paint “L0NG-B01” on it.
My original comment was going to be “that boi looooong” and i don’t know why I changed it…I plan to use “military style” stencils to paint “L0NG-B01” on it.
I gotta learn to stencil on lettering onto my stuff. So hopefully i can take some notes from you!
A printable template from a Google search, some contact paper, and an xacto knife. At least, that’s my plan…
Alrighty. Doing a little bit of this and that on the rocket today. Starting with some letters.
Printed letters from a random site that likely gave me computer herpes. Raided the wife’s craft corner for some Cricut Transfer Tape. Taped them together, and used an xacto to cut out the letters.
Slapped the stencil on, taped it up, 2 quick shots of spray paint, and viola! I’m very happy with it, I was hoping for just a little bit of overspray to make it look more like old military stuff, and I got exactly that. Neat!

And mounted the rail buttons. Used 3/4” wood screws into the plywood bulkheads, and a tiny bit of super-glue in the threads.
Apparently, I invoked my “find a stud” method because I can’t measure worth a damn.
Oh well. Nothing a bit of filler and paint can’t hide I guess.

I can’t wait to see some flight pics/ video. And a picture of it on the pad!

Nice Job! What is the weight fully loaded?
Without engine, the entire thing is 64oz.
I'm not sure I would risk a 4+ lbs. rocket on a G motor. A G motor doesn't really have enough total Impulse to get the rocket high enough for a safe flight using motor ejection.
Just fly it on a mid range H motor, or even go with a I motor if the day is good and winds low.
It sims fine in OR (to about 450' apogee)...but since that's technically a "high power rocket" at that weight, and I want to test it on my property, I've decided to do the test flight with just the bottom half (and nose cone of course). I wanted that to be an option anyway, so at least I'll know everything in the bottom section is solid before going for certification.
Also, I'm a moron. It's 64.4oz with a G motor installed. 60oz "dry." (Not that it's much difference)
Yeah, that drops me to 43.4oz with a G78G motor installed, and should apogee at about 900'.
What exactly are you testing? I think I would just fly it on a H motor for the cert as a first flight. Are you really that worried about how you built the rocket?
What's going to happen when you put a large I motor in it? If you believe it can handle that, what is flying half the rocket on a G motor actually going to tell you?
Don't overthink this.
I like to fly rockets, and this allows me to fly this one a little sooner.
So, your point is valid and I have no rebuttal.
