    How Would YOU Build This Weird One?

    Launched in April- probably the most stable flight I've ever seen for such a weird-shaped rocket. Need to convert this to a dual deploy rocket for next flight.

    Scratch-Built 6" Dia. "Honest John"

    Fun making bigger rockets- usually J800 motors- occasionally K1520 motors for the "one & done" HEAVY builds like Marvin Martian Jr. & Delta Clipper- those two rockets were so bulky/heavy that carrying them to & from the launch field once was enough for me- I kept the nosecone from each as a...

    Scratch-Built 6" Dia. "Honest John"

    Had Always Ready Rocketry cut the fin slots for me, as well as cutting a couple of the body tubes to length. Looks like I've been away from this project for 2 1/2 years- HATE cutting 6" Blue Tube with my razor saws. Fins epoxied to the 3" dia motor tube, and epoxy fillets added. Cut the 1/2"...

    How Would YOU Build This Weird One?

    Been catching my breath after this April launch! Sorry for the late responses to your posts. It actually was single deploy at apogee, with a 14 foot chute from the nosecone section, and a ten foot chute from the fin section. If I get the nerve, I'll figure a way to make it a dual deploy for...

    Crazy Idea? Using Upper Chute Apogee Deployment to Shake Loose Fin Section & Attached Lower Chute

    "Not a Rocket Scientist" had a successful maiden launch a few weeks ago. But the apogee ejection charge for the fin section, which contained a deployment bag for the 8 foot chute, severely charred the bag and even created a small rip in the bag (chute was not damaged). Since the fin section...

    Creating a Nosecone for an 8" Dia. Big Bertha?

    Any thoughts a to creating a nosecone for an upscale Big Bertha? If I do this build, I plan to use 8" dia concrete form tubes as I used for "Not a Rocket Scientist". Upscaling the rocket to an 8" diameter would make the rocket 10 feet tall. I'd want to weight the nosecone so that I have no...

    Repairing a Cracked 1/4" Plywood Fin?

    I have some of that- will use it. Thanks for the tip!

    "Not A Rocket Scientist" Mega-Build

    Based on "The Far Side" cartoon- 8 1/2 feet tall, 45 pounds, 8" dia. with 12" dia. fin skirt. Successful flight April 15, 2023 with Tripoli Mid-Ohio in South Charleston, OH. Youtube video attached. Check out my other launch videos, including "Marvin Martian Jr" two years ago, at...

    Repairing a Cracked 1/4" Plywood Fin?

    Cracked a fin upon landing this 45 pound rocket- it still feels quite sturdy, but flexes a bit compared to its neighbors. What are best practices to repair a crack like this? Thanks!

    How Would YOU Build This Weird One?

    About a year late for various reasons, but we had a breathtaking launch on April 15, 2023 with Tripoli Mid-Ohio at South Charleston, OH. The rocket ended up being 8 1/2 feet tall, 45 pounds fully loaded, and 8" dia. with a 12" fin skirt. an Aerotech L1520 Blue Thunder reload got it off the pad...

    Upscale Gemini Titan

    Just ran across this thread. I cheated & used one J800 motor with two upside-down aluminum shot glasses on either side as nozzle simulations. 6" diameter Blue Tube with a homemade capsule. Polycarbonate fins. Lettering from Stickershock23.

    Limits of the base drag cone?

    Yikes- please post a video of the flight when you decide how to handle this. My only thought- put as much weight in the nosecone section as you can (I use BB's & epoxy), launch from the far pad & make it a heads-up flight. As long as you are throwing a LOT of initial thrust at the rocket & not...

    Limits of the base drag cone?

    When in doubt, just add nose weight. That's what I did for my 6+ feet tall Saturn V & Skylab Saturn V (same rocket- different nosecones).

    Alternatives to Elmer's Glue All Max for Grain Bonding?

    Just received a 4 oz. bottle through Amazon- free shipping- and it looks nice & runny inside the bottle. I have a L1520 to prepare for a November launch of this 8 1/2 feet tall version of The Far Side comic "Not Rocket Scientists". Nosecone on the floor next to the rocket. 8" diameter with a...

    Alternatives to Elmer's Glue All Max for Grain Bonding?

    Thanks! I'll buy a 4 oz. bottle through Amazon. I suspect a number of folks would like to know your comparison of the foaming characteristics between the Elmer's and Gorrila products.

    Alternatives to Elmer's Glue All Max for Grain Bonding?

    Wondering if this product is still made, or what is out there on Amazon is old stuff. Any proven alternatives? Should I just buy Elmer's from an Amazon seller & not worry about it? Thanks!

    Alan Shepard's Freedom 7 Mercury Redstone

    Thanks to all. I'm bringing the capsule section down on it's own BIG chute- at about a 60 degree angle so that the edge of the base hits the ground first. Hoping to keep the escape tower in one piece upon landing. If not, I'll epoxy it back together, or buy another 3D-printed tower section from...

    Alan Shepard's Freedom 7 Mercury Redstone

    Finally finished the painting of this 1/12 scale Mercury Redstone. 6" dia. Blue Tube construction & almost 8 feet tall. Boyce Aerospace 3D-printed capsule/ escape tower. Stickershock lettering. Took a little liberty as to the positioning of "UNITED STATES" relative to the fin positioning...

    I'll have one or two Mobius Actioncams on the rocket.
