About 10 Years ago I built a Pershing II based on the Estes BT-80 body tube. I launched the Pershing II on a D12-3 for the first time. It was a bitter sweet launch. Perfect launch and it went up straight as an arrow. Chute deployed fine, but the wind Continue Reading
I revised the fin can adding in some detail at the bottom of the fins, and added the wedge shaped coupling connectors.
I figured out the problem with the nose cone. It was a two part issue, while some of the polygons appear to be properly touching in Tinkercad, they really were not, there was a tiny gap. The second issue was a mistake I made in Tinkercad for the wall thickness, Continue Reading
While I was searching for the Mercury Redstone scale date, I was reminded of the US Army Redstone Missile. I used the scale data I came across and created a 3D model of a nose cone in the same 1:52 scale for an ST-16/BT-56 tube size. I printed a test Continue Reading
I decided to try my hand at making a 3D part and created a fin can for it. I didn’t do a lot of detail, did about what I would have done in balsa. And it certainly isn’t scale, but it turned out pretty good I think. The fin can Continue Reading
The Mercury Capsule with Escape Tower is assembled and glued. I still need to create a shock cord attachment, and if necessary add some weight to the nose. I am really happy with how this came out.
I decided to reprint the Capsule with the new printer. Not as obvious to tell from the photos, but in person there is quite a difference in quality. I’m glad I reprinted.
I may have pushed the limits on my 3D printer with this one. After a number of failed attempts I was able to print the tower structure for a Mercury capsule. This is at 1:52 scale designed to fit in a Centuri ST-13 body tube (Estes BT-56). It is printed Continue Reading
JackHydrazine did a terrific job creating 3D files for the Enerjet 1340 fin can. The file can be found here: https://www.thingiverse.com/thing:3641770. I printed it overnight and it came out really well. I used PETG. It’s strong and can withstand higher temperatures like ABS and is not brittle like PLA, it Continue Reading
To Engine Mount or Not to Engine Mount? That is the question. I have a dilemma. An 18mm BT-20 engine mount will not fit in the space left from the BT-4 tank tubes. I was planning on cutting out an 1/8 of an inch down the length of each BT-4 Continue Reading
