Steely-eyed missile man? Running @kegrocket. Opinions own.

@BestCoastBrian @Astro_Clark I didn’t work on the fins, but my understanding is that waterjet is a pretty decent way to cut CF with the proper parameters. Second only perhaps to using a compression milling cutter.

@daverattmanndoo @matt_dahle @HalfCatRocketry @TurbulentSphere Hey @daverattmanndoo, I’ve heard about your work. Have been trying to find a way to get in touch for more info. DMs open.

LT-54 was heavily inspired by @TurbulentSphere’s “Tiny Liquid” and relied heavy on @HalfCatRocketry’s generous knowledge contributions to the field.

[Ryan Callahan @rycallahan]

This is a pretty special moment in the history of amateur rocketry. Conventional liquid propulsion historically not been allowed at a sanctioned national rocketry event… Till now! Honored to be a part of the first cohort of (insured?) liquid rocketeers!

[Half Cat Rocketry @HalfCatRocketry]

Half Cat Rocketry will be conducting a demonstration of Mojave Sphinx at Tripoli's BALLS 32 event this September, alongside @rycallahan and @TurbulentSphere with their liquid rockets!

[Ryan Callahan @rycallahan]

I will be representing what I’ve been calling LT-54 (Liquid Tube 54). It’s a self-contained liquid rocket “motor” that fits inside of a CTI 54mm solid rocket motor case. It makes 120 lbf for 3 seconds and runs on nitrous oxide and isopropyl alcohol.

@BreakingTaps @kegrocket Thank you! It is a little painful moving all the tools and shop equipment I’ve accumulated. We are okay workshop-wise in the new place… but I will say the rocket had to come in through the window 😅

[Ryan Callahan @rycallahan]

In 2022 I moved into a goofy little garage-converted-into-apartment specifically to have a place to start building @kegrocket. Today is moveout day.

There were plenty of more conventional ways to live, but we do strange things for our projects.

This has been a lot of work on top of managing and executing the actual @kegrocket project itself! Huge respect to anyone who does this on a regular basis 😅

@BestCoastBrian @hungrytacos15 @kegrocket @Astro_Chuck @rycallahan looking forward to his 3rd tweet

[Ryan Callahan @rycallahan]

Before launching KegRocket I made it a goal to get High Power rocket certified to develop and sharpen operational skills prior to launching the big one. Two unsuccessful L1 attempts yesterday (CATO and a broken fin) but had fun and learned so much more.

Here we go again

@SSMEgull @kegrocket @ky_saber Thanks for the tip!

[Ryan Callahan @rycallahan]

@BestCoastBrian What are you doing there?

[Ryan Callahan @rycallahan]

@BestCoastBrian Yerbs are the only energy drinks I don’t have to wear Oakleys while enjoying

[Ryan Callahan @rycallahan]

@inafoxhole Someone done destroyed their wheel :(

[Ryan Callahan @rycallahan]

@ohitstarik Please do. Cool garage!

[Ryan Callahan @rycallahan]

@unrocket Peroxide burn?

[Ryan Callahan @rycallahan]

@ohitstarik Honestly I’m just surprised it’s not Twitter for Nintendo DS

[Ryan Callahan @rycallahan]

Just got a Twitter!
