I made a video showing how: th-cam.com/video/GIWnE7Zk9D4/w-d-xo.html Basically it's a spiral ring so you just work it on around the tube and into the groove.
finally a real sugar motor build series! love to see the process of making a proper motor with aluminum. I wish i had some way to machine aluminum, thats why i wish pvc was a safer material.
@@MinuteRockets yeah. Ive been planning to simulate and make a motor out of pvc. My thinking is, if it fails, it wont be dangerous if im extremely far away behind a wall and no one is around.
If either a steel, aluminum or a pvc motor case CATOs, the sharp aluminum fragments will often go farther than either the steel or off fragments. Distance or a barrier are your friends.
Thanks! The o-ring seals the motor, but it's the retaining rings that clip in the grooves in the ends that retain the closure. They are rated for about 10,000lbs, so that is more than good enough for what the motor will generate.
Good question, that's one thing I've wanted to experiment with. My 3d printer is not large enough to print a full liner, but I might be able to do segments that are staggered from the grains. The 3d print material does get brittle when it gets hot, so I'm not sure if it will hold up. I might try it if I get a chance.
Thanks! I haven't really thought about it too much. I wouldn't mind making some, but I don't have stock for 54mm yet. I'll let you know if/when I get some.
Great video! How did you get the thrust ring into the casing after cutting the groove?

First time viewer but not the last. Definitely not the last, great work!

Thanks, yeah it's too bad PVC is so brittle. I fly with my local Tripoli club, so it's a no-go for me anyway.

@@vertex3243 Yeah, I know many have done it, so there's a lot of examples. I'd say for sure have something between you and the motor if you try it.

Nice work on the forward closure! I am looking forward to the nozzle video.
Thanks! I'm editing the nozzle video now so hopefully soon.
@@MinuteRockets its been 4 days🥲
AMAZING SERIES! Cant wait for the next episode. Thanks for sharing
Great series, well explained. Thank you
good job congratulations
Hey fam, probably don't want to be using WD-40 to lubricate, a lot of people do but it's for rust removal not lubrication.
How did you make the nozzle and the rocket launcher?
Nice build man!!!, but will the o-ring be sufficient to hold the closure in place, won't you be needing some screws?

What aluminum grade is the tube and what is the thickness?
It's 6061-T6 drawn tube, 1.5 inch OD, 0.083 inch wall

Awesome
does 3d printed liner work on this?

Great work! Have you thought about making these cases for sale? I'm in the market for a 54mm case for KNSB.
Thanks! I haven't really thought about it too much. I wouldn't mind making some, but I don't have stock for 54mm yet. I'll let you know if/when I get some.
sir can you tell me how to decide dimensions of the rocket motor
Check out my first video on the design, I go over all of that there.
Sir I am aeronautical student & I am thinking of doing this project
