    • Very productive evening tonight. The last of the green is gone and all but ceiling trim is done...

       

       

      I think I need to work on lighting soon.  I've had all the parts since Christmas (thanks Marilyn) - might make sense to do that before putting track back.

    • I haven't decided on car spots yet.  The coal hopper is on the main which may, or may not, be car spot. The foreground track will usually have one or two cars.  The photo angle would not be blocked by the cars when taken from ground level near the right switch.  In my mind, the world down at track level is completely separate from the whimsical world up on the shelf. For that reason the flats on the operating railroad stay below the shelf level.

    • How often will you have cars set up like this ?

      It looks like the building would be hidden. If it stuck up ... Hey what that in the corner ..

    • Sean -  The original plan was to go as high as where the paneling ends and the black begins. There is room to go taller, but I'd like the keep the focus below the black trim on the upper shelf.  I will probably go wider - or add a different flat to the right between the black and the book case.

       

      I commandeered a few more square feet of black vinyl.  The green will be gone forever tonight!!!!!!!!!!!!!!!!!!

    • In this ^^^^ pic .. how tall is the building originally going to be ? It looks like you can go as tall as you would like.

    • Looks fantastic, Jon...

    • Jon that's coming along nicely..

    • Jon, that came out quite nice.  A lot of work for three car spots, but in the end well worth the effort.  When you get McGillicuddy's facade and the trestles done you will have a great place for photos and videos.  Thanks for allowing us to tag along on this journey.

    • Today was track and roadbed day.  Eventually I will build wood trestles, but for now, black PVC roadbed stands in for the trestles. I cut track to fit from 7 foot code 332 aluminum track by Accuctraft. The aluminum track is super easy to cut on the chop saw with just a little clean up with a file or sanding disk. Final track alignment...

       

      Final switch machine positions...

       

      The final grade measurement on this short 4 ft section of track is 4%. The box car still fits....

       

       

      All of this is just one step above dry-fit. screws are in, but it will all come apart. I want to yank it up now and put down the grass mat and finish the edge trim. I also need to cover that last bit of green concrete block. I can't wait to get back to work on McGillicuddy's to finish this scene...

    • Pay no attention to the man in the window!  Yesterday's goal was achieved. The large plastic shelving unit that I set up to hold all the stuff removed from this area for demo was emptied out and a home found for everything. Outdoor buildings inside for winter went up in the 'Shadow Box'. A bunch more stuff got loaded in and on the antique book case. The white plastic shelf unit that used to live here was eliminated and both shelving units were hauled up to the attic until they are needed again. The latest long shot shows the progress...

       

      Construction is now complete, except for a little more fake grass and some aluminum trim to dress things up.

       

      With clean-up done I turned my attention back to that pesky switch mechanism.  I think Al correctly diagnosed the problem even though I didn't know how to measure the angles; when I looked at the two cranks as a matched pair, I noticed the difference.  The angle error was compounded by a weak mount for the closest crank causing it to lift (as Roo noticed). The solution was to improve the pivot mount so it can't flex and move it to the other arm correcting the rod angles...

      With these changes the throw gets mounted about .75" closer to the camera which now interferes with the throw from the right switch.  I can either go through hell to shorten the rod and cover (everything apart again) or add a short section of rail to move the switch.  Being lazy I'm going with the second option.

    • Dan not to worry you only see his head .. must be a short guy...

    • Jon, not sure if you looked at these pictures very closely, but there is some dude taking pictures through the window   I like your storage solution.  Good use of available space.

    • I've moved on to getting the basement put back together. The switch tweaking can be done later.  I did add another clamp Roo, but on close analysis the problem is the bell crank mount at the throw. It is not rigid.

      I added an end to the drawer with 10mm coroplast, then put it back in place and got it loaded up with my grapefruit container storage system!  Here are the latest pics...

       

      Today's project is to install the film on the left pane of the window so I can start loading junk up into the "shadow box" area.

    • One simple stupid note that you will understand. Perhaps your conduit is pushing upward when closing because you don't have it strapped down at the end.  I personally would move the conduit clamp closer to the end before I play with tweaking it.  The solid rod on the bell crank also looks like it's a bit tight in the hole (.........) maybe drill out that hole a bit for some slop. I played around a little with bell cranks in the past and they can be a bit tricky....

      Honestly I don't even know which end you are controlling it from beer 4!

      Jon,

       

      from an engineering perspective are you bell cranks moving thru equal angles relative to the center of the points? this may account for an error in the amount of throw translated between locations.

      I wish I was smart enough to answer this question    So, I'll do what I usually do in such cases; guess.  I didn't make any measurements and when it came time to screw the switch to the bench I wasn't able to see very well and what I could see was from an off angle.  Both bell cranks are mounted on a beam that is roughly 90 degrees to the track, but likely out of square by several degrees.  The throw rod and the push rod to the points is also at roughly 90 degrees to the track. The carbon fiber rod curves a bit, but is generally parallel to the track.  Does that give you any hint?

      If I disconnect the rod from the throw, I can manually move the points cleanly to both extremes using the bell crank at the throw.

    • I will have to open up a spare and look to see if there is enough room inside the housing for the rod to bend up, rather than down.  Not sure if that would help as it dos not seem to be binding at all.  I could also flip over  the bell crank making it closer to the tie which would straighten the rod a little. It is a major pain to open that little clevis to disconnect the rod.  If I am going that far I might try adjusting the length to get the trow more even from position A to position B.

       

      All of this is low priority now since it really is no big deal to give it a nudge after it's flipped.

    • Is it possible to flip the rod coming from the throw .. so it is mounted under the cam ? It might be binding.

    • Linkage was installed last night.  Reaching through the tunnel to screw things down was a bunch of fun.  It is now functional and clearance tests have been run making sure the throws (without the indicator) do not interfere with my mobile clearance gauge.  It works great to open the switch (pull on the long rod) but isn't perfect pushing. I traced that problem to the throw itself. I might be able to tweak the gear positions to resolve it, but for now a quick push on the bell crank gets it done.

      With this done, I can finally put the drawer back on the track and start loading it up. This project is two days away from 2 months in. I would like to be able to get rid of the temporary shelving holding all the stuff removed from this spot to allow construction to happen. Hopefully this weekend I can wrap up construction details and clean!
