Starting the build of my Semroc Saturn 1B. The Rocket was gifted to me by a fellow CMASS club member who was clearing out his build space. Challenging build ahead with lots of attention to detail required. Here goes nothing!

Started to build a Fliskits Morning Star, and saw that the card stock with both the transition shroud and the 5-fin marking guide was missing. Immediately set out to design a shroud. Some careful measurements and one new technique later (creating a ‘loft’ between two sketches in Fusion 360) and...

A quick post hoc thread on a rocket I designed and built. Parts printed on my Prusa i3 MK3 3D printer. Designed in Autodesk Fusion 360 and Tinkercad (also from Autodesk). 3 fins and a nose cone built around an 18” Fliskits BT-60 tube. More to follow. Much of this was discussed on a dedicated 3D...

Just a quick build thread for a simple 2 motor cluster rocket that will use D or E motors. Starts like this: Had some Fliskits BT-70 tubes and a nose cone laying around, so designed this 3FNC rocket.

Probably not new. My D-Region Tomahawk needed its 3rd new cord, and I've had enough with teabags. Here's the interior after cleaning out the old tea bags:

Been staring at this spool for months. I could have just done a standard 'motor in the center' approach, but figured, why not go for something more interesting. It will use a cluster of 2x18mm motors. The motor tubes will be sealed at the top with fixed nose cones, and vent into the spool hub...

I know I'm not the only home canner out there in rocketry land. Or maybe I am. Even though I live in the city on a postage stamp sized piece of land, I grow tomatoes every year. Ripening is all but over, so it's time for pickled green tomatoes. Best pickles ever by Thanksgiving!

Just about a perfect day, high clouds over this our low-mid power field. Well over 200 flights by the time I packed up at 2 pm. Here's a cool video of one of our member's cup rocket, the Latte II: https://youtu.be/Ur5494WhIfk And here's my guy prepping his Alpha III. This is what it's all...

Well organized event - hats off to the leaders who made this happen. My flying was so-so. I lawn darted one rocket because I had simmed with a 24mm F51 Classic but in my morning stupid stupor bought and flew with the much less powerful F51 Blue Streak. Delay of 7s was absurdly long for that...

Hats off to the artist for starting with Alway's illustration and doing a beautiful rendering of it. I'll be adding one to the shop wall. https://www.universetoday.com/118742/the-worlds-rockets-to-scale/

Up until today, I didn't. Used some money I jointly won in an innovation contest at work to buy this: My garage is big (22x22) uninsulated and drafty - this really helps. (I had the tank already from the BBQ grill, good winter use of the propane).

This will be a short and straightforward build and thread. I got this off the Madcow July 4th sale, just getting around to building it. Will be stock build, Aeropoxy adhesive, JB Weld for the retainer. Parts will get cleaned with denatured alcohol and roughed up with 180 grit sandpaper before...

Damn you, time change. Damn you straight to helllllllllll!

Though I like Alpha's for sentimental reasons, I've never liked how my Super Alpha flies. Its always been prone to heavy weathercocking, and seems to think its a jetliner, not a rocket - loves to fly sideways. Those big fins, those small motors... So I did some work in OR to clip its wings and...

I picked this up at the July 4th Madcow sale, having always wanted an Aerobee. From what I can tell it is a minimalist 1/5 scale model of the sustainer section of the RV-N-13b (see https://www.astronautix.com/lvs/aeree150.htm.) By minimalist, I mean it has the general appearance of an Aerobee...

October as you may know is Breast Cancer Awareness Month. Not sure if it's been done before, but I'd like to suggest we all make an effort to fly pink rockets at one or more of our October launches, and if possible, take up a collection at a launch and donate to the national organization. Some...

At today's CMASS launch we had a real treat. And no, I don't just mean the cake that Jim Flis brought as part of his annual Fliskits party - which was of course very yummy. We had all 4 presidents of the New England clubs present at the launch. Here then, is the Mt Rushmore of New England...

Somewhat of an odd-roc, but on the surface, it looks normal. Twist is that the chute will eject from the rear. This will be a quickie build thread - rocket is mostly assembled at this point, will post the current state picture when I get home tonight. Here is the design from OR: Ignore the...

I'm making the switch from standard 9v batteries to these LiPo variety (400mAh, 3.7v, https://www.sparkfun.com/products/10718). They test fine with my Stratologger - tested each of main and drogue outputs twice to convince myself that the current limiter would hold up and e-match would fire...

This is just my experience with using ES6279 paste, not an epoxy war thread. I picked up the quart kit of this epoxy (the tan paste variety) and successfully used it for fin attachment on the 'Tick'. (See https://www.rocketryforum.com/showthread.php?t=63897). It worked very well out of the...
