    I started gluing in the Terrier motor mount today.

    Printed centering rings, which I usually glue back to back to thicken. Channels for wire chases for possible future staging.

    I printed a piece to anchor carbon fiber slats that go through the fins. One centering ring is above it, another will go below after everything is glued in place.

    And in situ, with the slats in place.

    Used bondo glazing putty to fill in the epoxy lumpiness and the wave in the printed fins.

    My experiments at foam filling annular spaces didn’t turn out so well. I decided to support the payload sleeves with balsa strips.

    I finally decided to go with the Improved Malemute, rather then the first flight version Peter Alway documented. The difference is wiring chases down the sides of the motor. After a dive into Patriot details and finding some appropriate balsa in my stash, here's where we stand. My version will turn out a touch short - but I'm not entering it into competition.

    Scale would be 1/8 balsa - which I shaped by sanding and tried to warp with ammonia on a PVC mandrel.

    Well, I didn't get much warp, so I had to fall back on more sanding. Here's the end result.

    Charles,

    I had a thought . . . What about warping the sheet of Balsa, BEFORE cutting out the strips for the Conduits ? There would be a lot more "leverage" to induce the Warp.

    Were I to do it again, I’d do 2x 1/16” layers per channel. Shape, then glue stacked to thickness.

    I’ve shaped blades for helicopter recovery. I think a thinner material would have worked better.

    And some painting on the Improved Malemute research-style payload.

    So I’ve been painting up a storm. It’s not the best weather, and the gloss white has been a little runny as a result. So not my best work - but it’s good at feet. Just not inches.

    The Improved Malemute motor need a second orange pass before I pull the tape on the white chases.

    Getting close to decal time.

    Decals on. The last external touch would be a black stripe of t leading edge of the Malemute fins - the real ones have an ablative coating.
    I’m still thinking about it.

    Terrier Booster.

    Fin detail. This is actually the worst one. The angle setting fixture got messed up on this one.

    Terrier info sticker. With some liberties taken, like switching to a closer ordnance station. And nitrocellulose to APCP with a reasonable mass.

    IMG_1482.jpg

    Improved Malemute/Patriot motor.

    And the other side. The flight number containers my NAR number. The real 46 series is at about 30.

    IMG_1484.jpg

    I used the details of the Tomahawk despin module (from a Ute Tomahawk data bundle) to make graphics to go on the switch band. Above that is my model NASA payload, RCS module, telemetry unit, and 11° total angle nosecone.

    And stacked.

    Charles,
