    So with a better looking driver figure on the way for the Short Circuit, I'm thinking the same figure will go in the Atlas. But wait!........ What about the interior walls of Bill Muncy's "Office"? They were upholstered. I spent some time making a "Tuck-n-Roll" mold from a hunk a brass and Voila':..... 1/20 scale Tuck-n-roll.

    Now before some educated donkey (a.k.a. Smart A$$) chimes in, I KNOW the Blue Blaster had button tuft upholstery, but I had no way to make such a mold. Tuck-n-Roll is good enough for a SEMI scale model.......

    This is the newer Blue Blaster hull with the canard wing (and other upgrades), but the upholstery was the same in the '78 hull.

    What size would the diamonds be if you could?
    I might have something in the shop that could work and I could take a look tomorrow.

    The "rolls" in the tuck-n-roll were 0.0623" (slightly less than 1/16") and were cut in a brass block with a 0.0625" ball-end mill. The button tufts would be somewhere in the 3/32" spacing area and far more complicated to machine into a mold.........

    The panels aren't glued in yet, but you get the idea.....

    When I buy barrel blanks they come with this plastic wrap covering them that has a diamond pattern I was thinking might work for you. Unfortunately the diamonds are a bit larger than what you were looking for.

    Yeah, but it does give me a good idea......

    Not sure if this will work, but it's cheap and appears to be the right size.........

    Some idle thinking here......

    If you remember, I built a prototype to test parts fit and such before building the final version.

    DSCN0625.jpg

    The prototype is seaworthy and I've run it a few times, but the finish on it is still "preliminary"; you can still see a lot of wood grain through the paint. I'm not real happy with the shape of the cowl and the idea struck me to give the existing hatch/cowl assembly a LOOOONG ride on the belt sander and do something different. The rear wings/fins are fiddlesome and tedious to build and finish, so I'm looking for something to get around building more of them.

    This might be just the ticket:

    Default Kudos to J Mack

    While the exact product J Mack uses on his barrel blanks wouldn't work for a host of reasons, it did get me to thinking and researching. I bought a small sheet of that expanded aluminum mesh in the photo above with the penny. I just did a quick "test" and wound up with what I consider a completely usable "Diamond Tuft" panel. I'll make 2 more and use the tuck 'n roll panels as templates for trimming them.

    Looks great, your builds have given me so many hours of enjoyable reading with my morning coffee I’m glad I could contribute in a small way!

    Thanks for that J Mack,

    Much of what I do is experimental, going where no man has gone before, and I appreciate it when somebody takes the time to read what I write in these forums. I'm glad you found it entertaining and I appreciate your contribution!

    Hmmm..... I just found 4 rather dusty Atlas kits in the back corner of my hangar.....

    What to do; what to do??

    So I'm looking at Prototype #1 and thinking of how I'm going to revise the cowl. I thought about Miss Tri-Cities, but I was concerned that the opening in the hatch to clear the (electric) motor would fall in an "open" area of that hull, just in front of the location of a scale Merlin engine.

    Then I got to thinking about the 1970 Pride of Pay-n-Pack with the twin supercharged Hemis.

    The cool part about this hull is no wings/fins to deal with (other than the central fin), and 3D printed supercharged Chrysler Hemi engines are a dime a dozen and can be printed at any scale.

    Has anybody ever noticed that Chuck Thompson looks almost EXACTLY like Bill Muncey? They could be twins!

    Seriously though, the 3D printed drive figures have arrived and they are FANTASTIC! The level of detail is outstanding.

    I found a video of the first run of the Atlas Prototype. As you can see, I had WAY too much lift at the prop, causing it to hop all around. Spun out in the first turn because of the hopping, then disintegrated the plastic X430 prop.

    I've since raised the strut and moved the battery back a bit.

    Well, I went to a new pond today with my friend Wayne. Now I don't have to worry how to finish the prototype hull. Wayne finished it for me. It was still floating after the ramming, but thanks to fortune and the generous amount of foam built into the sponsons, all the mechanical and electrical components survived and stayed dry. As luck would have it, it got flipped over on it's back so the half-dollar sized hole in the bottom of the hull was above the waterline. The other quarter-sized hole was in the rear non-trip area which in essence is a sealed compartment.
