    I first had the rocket built and held the ring in place and marked the ring supports on the ring
    I cut some tape strips and applied on the rings where the supports go.
    Then while wearing gloves and holding ring by the edges, I sprayed the insides. Since the ring supports are not preset the painting is easy. And helps prevent runs.
    I also put tape strips over the edges of the ring supports and pre-painted the tube and supports.


    I will do a final coat of paint to cover the fillets and issues where the tape strips were not perfectly aligned and a bit of bare tube shows.
    I may actually use a brush for the internal cleanup to avoid runs.

    Thanks, that’s what I figured was necessary but never give up hope that someone has a magical trick to make it easier. ;)

    Slow day. Primed the Estes Atlantis and worked the nacelle pods for the Sirius Atlantis. The Sirius nacelles didn't come out too bad. They are just dry fit at this point.
    And bought some stuff for the GT.

    So what is this?

    IMG_3968.jpg

    Since the main part of the Sirius Atlantis is painted, I wanted to pre-paint the nacelle pods

    IMG_3969.jpg

    Some clamps to hold and counterweight and we're off the the paint area

    IMG_3972.jpg

    The directions warn to do very light coats so the primer does not attack the plastic. So it took 3 light coats to cover.

    IMG_3970.jpg IMG_3971.jpg IMG_3973.jpg

    Now for cleanup.....

    For the Gemini Titan, starting to work the motor mount

    Pre-painted the motor tube ends and inside the nozzles
    IMG_3974.jpg


    Masked the capsule and 3 coats of black

    IMG_3975.jpg IMG_3978.jpg



    For the Sirius Atlantis, used some bondo to clean up the ends, and then another coat of primer

    GT time. And an extra day of effort

    Cut a bit of extra BT80 tube into a coupler. Cut some windows to lighten the weight and glued the tube holders. I'm going to also use the 1/4" lugs to hold the removable fins. Made holes for those. They ended up a tad big so using some tape to build up the lugs.

    IMG_3995.jpg IMG_3996.jpg

    Painted the ends of the motor tubes and inside the nozzles. Dry fitted

    Adding a solid balsa piece to represent the various supports and tubes. Also some dowels for the start of a structure. These are CA'ed to the tube guide

    Estes Atlantis - used a brush to touch up where the spray can does not reach
    IMG_4007.jpg

    Sirius Atlantis - painting the nacelles

    IMG_4005.jpg

    Gemini Titan - Mixed up a bit of black epoxy to glue the nozzles in place
    Glued motor tubes to mount, and started adding details

    Needed some smaller dowels, didn't have any and didn't want to wait to order some. Came up with the idea to use some toothpicks. But they are the square type.
    But a bit sandpaper and a drill changed square to round.......

    Attached the bridge to the Sirius Atlantis

    IMG_4015.jpg

    Touched up the painting of the Estes Atlantis (no pix).

    The Gartrell and and GT capsule needed paint cleanup as well. Discovered I had run out of Rustoleum 2X gloss white. Picked some up Saturday.
    Did the cleanup on the Gartrell (no pix) and the capsule (that one I got a pix of)

    GT - Applied First Vinyl!

    Just plain color on the 3D printed interstage I got from shapeways.

    Using the light shining from rear to cut out the vinyl.

    IMG_4039.jpg

    All "done" (still need a do a bit of cleanup)

    Worked on the motor mount for the GT. Used epoxy for the joints of the 2 motor tubes to the stuffer tube. I wanted to make sure all edges were protected
    IMG_4041.jpg

    And then back to the Sirius Atlantis - Installed the bridge deck and nacelles

    IMG_4044.jpg

    The tape stripes were a bit over size, so time for some more paint. Before and After...

    IMG_4042.jpg IMG_4045.jpg



    And last for tonight....
    Skinned the GT capsule. I did have some issues. Fortunately, 2 sets of capsule skins are provided allowing me to fix my issues....

    Philosophical question ---- If you plan on mucking up, and then make the mistake, did you really muck up? After all, you planned for it, right??

    When I was gluing up the motor mount, the instructions tell you to use the main tubes to ensure the motor tubes will be straight.
    While I tried to be careful to keep the epoxy away from the edge, well...
    I was concerned that it might get stuck so I did make sure it was located in the right place. Thank goodness....

    Been doing the main body skinning and started applying the decals to the Gartrell and Estes Atlantis

    IMG_4059.jpg

    GT - Trying to touch up the edges of the interstage I did mess things up - unplanned.
    I sent a message requesting to buy a replacement just for that section - waiting for a reply.
    Although with my error it has a sort of weathered look......

    Here. Actually got worse overnight. I think some of the cleaner I was trying to use got behind the vinyl.

    Yes - it has its launch lug. Just not visible in the shots I took...

    IMG_4064.jpg

    So now I get a copper lollipop!

    IMG_4065.jpg

    Wait - that's not a lollipop. It's the antenna for Sirius Atlantis

    Like the antenna on the Estes Atlantis

    IMG_4068.jpg IMG_4067.jpg

    Still waiting for the paint to dry on the Sirius Atlantis before I can decal and for replacement skins from John at Accur8 for the GT, so things will slow down a bit.

    My next major challenge? Deciding what to build next........

    I clear coated the Gartrell and Estes Atlantis, No new pix - can't really see clear........

    I put the Sirius Atlantis by a heater which helped, and started to do decals. There are lots of decals........... Figure a minimum of 2 more nights

    So the Sirius Atlantis is now done - except for the clear coat... (LOTS of decals!)

    Some shots of the base of the GT. Not really scale, but has some of the bits and looks OK from from a distance

    IMG_4087.jpg IMG_4086.jpg

    Skinned some tunnels and started attaching

    GT fins - Got some 0.05" thick acrylic sheet and some 1/4" round acrylic.

    Cut the sheet into 2.5" x 2.5" squares. Used a combo of sanding and torch to clean up the edges.

    Glued 2 together at right angle using thick CA on wax paper
    IMG_4092.jpg

    I had to build up the rod thickness with some tape

    IMG_4093.jpg

    And then used CA to glue the rod to the fins

    IMG_4094.jpg

    This approach added some strength to the fin joint as each fin now has 2 glue points - fin to fin and fin to rod.
    If I had just glued the fin directly to the rod there would have only been one glue joint.

    Here is the fin unit on the rocket

    We used to bend acrylic sheet like this with a strip bar heater - that might have worked here for the 90° bend maybe?

    IMG_0533.jpg

    I’ve seen some instructions online on how to make your own strip heater.

    True, but it is rare that I would use clear fins so I'm not sure it would have been worth the bother to build my own....
