I'm bored. So I'm putting this here. If it's going up, it's gotta go somewhere.
In what will probably be short bursts, I'll document the build of a Frankenstein ARLISS-M. Going to be made mostly from resurrected parts, on the cheap. If that's possible. (Gotta be. I'm retired/disabled. That's spelled u-n-e-m-p-l-o-y-e-d.) Got a/f tubes, nosecone, couplers... all donated. Got a couple of accelerometers being generously added to the donation pile by a very good friend, too.
Got a nice chunk of FWFG a/f with the internal fin can already installed, and mounting holes for the fins already drilled. This booster section a/f is well used, but will fly again. Got a big bag o' fins. Some new, most used. Think I'm going to give the new ones to my buddy, and install some reworked, used fins on Frank-Can-Stein.
First order of business, the motor mount and motor retainer. Located a 24" hunk of 98mm phenolic wrapped in 4 oz glass in the "old tubes" box. That'll work. Could order plywood c/r's and an Aeropack retainer, but where's the punishment in that? Already own a lathe, a duke-load of tooling, and got a big ol' pile of al-you-mini-uhm...
Start with some 6061 bar stock...
Add a generous portion of turning perfectly good aluminum into curly, double-edged razor blades...
And come up with a forward centering ring, a 98mm motor retainer with knurled, threaded nut, and a thrust plate.
Lousy pics cuz I'm a lousy photog using a cheap camera.
The retainer is an interference fit into the recess in the thrust plate. Heat one, freeze the other, put 'em together, one piece. But being a belt-and-suspenders kind of guy, I'll install a few screws inside, just cuz they'll fit. And this is an ARLISS. No messin' around with ARLISS.
