    Very convincing rivets !
    Once you get the grime weathering between the rails, the low/transition to the outer ties will disappear.

    How well does the turntable center to the stall tracks? Without a stepper motor, many have used the rolling wheel/detent method.

    Now, I expect you to junk that electronics case and use only the few LED’s you need so there is a nice graphic. ;)

    As I recall, that was one of the "Casey Jones" excursions. Sadly, efforts to save the 2626 failed. :(

    It has a 4 wire stepper motor, and indexes good if it don't slip a gear tooth, however it does slip teeth no and again. The pit is molded oblong on my unit, so the gap between the bridge gets wide and narrow as it rotates. I am sanding the approach tracks back a but to help prevent the gear skipping teeth. AN ever so slight bit of resistance and it skips teeth throwing out the index. That's why they added index buttons to manually correct alignment.

    Yes I will mount LED's in the front facia, I ordered flat top 2mm LED's with a 4mm long light pipe. I still need to find 4 nice momentary buttons that are low profile.

    Looks like they installed the turn table arch a little off to the side : )

    After I go here:
    https://earthexplorer.usgs.gov/
    Type in "Lester WA" hit enter.

    Then go to Data Sets. Click "aerial imagery" and check the 3rd box "aerial photos single frames". Then click results.

    OK, I finally got it to work, downloaded a 75MB tif tarball.

    And after you get the image it may not be North pointing up. Sometime you have to really study the photo to get just what it is and rotate as needed.

    Yeah, I had to use Corel Photo Paint to open it, because it is so large a file, then find my target, then zoom out, and rotate, then zoom back in.

    Hi, Robert
    Are you aware of the Archistories Rokuhan turntable upgrade kit? It's worth a look. Item ARC-103161. Jim

    Oh yes, I have looked at the Archistories kit, but it does not look like the Lester turntable. I think with a bit of effort I can get a better match. :D

    The Archistories TT enhancement kit does look very good, but it's a modern style.

    The investment seems worth it (necessary) to enhance the appearance. Out of the box looks real toy-like. I like what you are doing: going for the prototypical look. I'm sure it won't look the same when you are done with it. Jim

    I was almost done with it today, but ruined it when trying to apply static grass. My static grass machine burned out, and it all clumped up, then the pit warped.

    So I tore out the bridge sides, and pit floor, and started building a new set out of styrene. I spent the day getting a electronic fly swatter from Harbor Freight, and rebuilding my static grass dispenser. That's OK, I will apply the "styrene pit floor/bridge sides assembly" weathering, and static grass on the bench, then mount in the turntable this weekend. I often go through a few revisions of a model till I get it right anyways.

    Made progress, I'm done with the turntable for now, and am working on the roundhouse:
    1.jpg

    So I cut a 1/4" 90 degree which the front of the roundhouse is glued to. The bottom will sit in slots, and the back and sides sit on a .025" step made in the base. I scribed the bricks a scale 6" x 12". The doors are 3 layers of .011" black polybak, with mylar window glazing fitting sandwiched in between the layers. I accidently cut 12 door cores, but only needed 6, and need 12 mullion pieces.
