    Although I'm sure he sympathizes with us I have a feeling John Beans relishes these posts. I'm also down an altimeter 3 that disappeared about a month ago along with a Mach1 Scat. He's watching his inbox for the order. I'm trying to resist but I know I'll give in eventually.
    That's a great shot!

    Maybe John needs to sell 6 packs, comes in a little cardboard caddy with a handle.

    Certainly took what little mystery there was out of the disappearance..which was very little.

    That is one cool rocket! Is it a kit or scratch build?

    Built a Semrock Orbital Transport, fulfilling a childhood pledge. Tried building the estes version of this when I was 13 and totally messed it up. Swore to my 13 year old self if I ever got the chance again to build one I would. One promise down, a few more to go!

    Back at rocketry after all my exams!
    Today I used my new mini lathe!
    Did this 1010 rail buttons in aluminum. Still need to test those on an actual rail. IMG_20190715_180937_259.jpg IMG_20190715_180937_257.jpg

    That's a scratch build by Neil, originally inspired by the movie passengers.

    Those are really pretty, but I'm sure you're aware that increased rail wear is a distinct possibility. Clubs are usually protective of their rails

    Yes I'm aware, I think I'm going to get some delrin. Those were mostly to getting use to working with aluminum.

    What did I do rocket wise today? So far, I've broken my own heart twice.

    I realized that the hand-cut slots for the chip can rocket (tentatively named the PT8-0) just don't line up well enough to the dados in the CNCed centering rings. I need to slot another damned Pringles can.

    20190715_093226.png

    Then I fitted a new and improved FDM tailcone to the motor mount for the BT50 WAC Corporal, whereupon I realized that the fins were out of scale. I looked back at the F360 file and saw that they are about 87% of the size they should be for a BT50 based rocket -- because I scaled down the drawings for a BT70 WAC Corporal -- not the drawing for the BT80 version I built to be my L1 rocket.

    I consoled myself by putting an aluminum tip on the chip can (PT8-0 -- too clever?) nose cone, because it is totally going to break mach.

    My shop is all higgledy-piggledy, with everything everywhere, as I struggle to complete a fairly large furniture project (on saw horses just out of the frame to the left in these images). I am not getting to a launch anytime soon, so I ought to put these in the box with the other in-progress rockets and get back to the big lumber. I probably wont't though.

    Well, FWIW I gave your post a "like" just for that name. Would have given you another for using "higgledy-piggledy", but only one per, thank you very much!

    Ah, PT8-0 was over my head initially.
    Maybe slide an "o" in there.

    Something rather ill-advised.

    I confess I only glanced at the build thread. (I think I'll go back and read it.) Why the paper tape on the fins?

    I am utterly at a loss for a clever comeback, so you'll have to settle for a "like".

    Estes 1/200 Saturn V lifting off from a 1966 Electro-Launch at approximately six minutes after the exact 50th anniversary of Apollo 11's liftoff. Pat Fitzpatrick launched his at the exact time (second picture).

    These are scaled down frame grabs from video.

    Got up 2.5 hours earlier to volunteer setting up the USSRC's 5k record launch of model rockets for the 50th of the Apollo 11 launch.
    Homer Hickam and Al Worden were there too.

    There are a couple threads involving it already, so I won't go into detail here.

    Drew up new BT50 WAC Corporal fins from scratch.

    20190716_140539.png
    BT50WACcfins.png

    These #22123 are actually just about the right scale for a ST-8 WAC Corporal and -- astonishingly -- I have a piece of ST-8 in the parts pile. I'll need to sand the fin tabs back ( by a lot), and I'll need to figure out a nose cone (easy enough to print one, I guess, but I might do something more arts-and-crafts).

    In the meantime, I am going to mill a new set of BT50 sized fins.

    Returned my incomplete Estes Majestic kit I bought at Hobby Lobby for a refund.
    Bought tubular foam insulation for the pvc rocket stands I'm going to build.

    Hope you get it done in time for the 20th... painting the roll patterns is every bit as hard as you've heard it is.

    Got a great start on a 2.6 inch Red Max clone. Using Loc body tube and 29mm mount. Plan on using the AT 29-40/120 reloads. Gonna try to modify a Loc nosecone to look correct to scale. Fins are 1/8 inch 6 ply Finnish plywood. Glad to be building rockets again. 100_2367.JPG 100_2368.JPG

    Is it me or do those fins look like bacon?
