A lot of lathe tools, such as this collet chuck, are threaded in the end of the Morse Taper, to accept a so-called drawbar. My collet chuck tends to work loose when I'm using it, which was a source of great frustration. So I finally did something about it. I found out that the thread size is 10mm 1.50, and a bolt would need to be at least 150mm long. Couldn't find one. As it turns out, there is a Grainger branch near me, and there is no shipping charge if you pick it up in the store. They had 10mm threaded rods on their website, 1 meter long, for $8. It only took a day to get to the store. The rod is stainless, and it was a bear cutting it. But I got it cut and chamfered the end of it, so it would screw into the chuck. I found a 10mm wing nut at Home Depot, and voila. No more loosening! Took me long enough!

Nice build and good documentation (via photos!) as usual Captain!
If no one else says so, I appreciate the time it takes to share!
Best!

For some reason I can't figure out, the forward coupler is way too tight. I've resanded the coupler and sanded the inside of the body tube several times, to no avail. I happen to have an old extra coupler, and it does fit. I'll have to make a new bulkhead for it.
Looking good! Curious that the one coupling wouldn't fit. Nice that you had a spare to move forward!

I'm not sure where the body tubes and third coupler are from. I apparently bought them several years ago. What's odd, is one of the body tubes is 30" long, and I don't know who sells or sold them that length. They are all the same diameter and thickness of LOC tubes. The first two couplers are from Rocketarium. One is a little thicker, and is considered for av-bays. It's just slightly smaller diameter. The one that's too tight is a normal coupler.

For the first flight, I'm thinking a G53 FastJack if I launch it at SARG, or a G64 White Lightning if at LUNAR.

Perfect painting weather today, so I went for it. Sealed and sanded the fins; sanded and wiped with alcohol the repurposed nose cone. I decided to paint the body tubes satin black, so I used Rustoleum Universal paint and primer in one. It covered pretty good!
