      Update:

       

      I dedicated the morning to various projects.  I almost fixed our homemade throttles, but the polarity of the 4-pin connectors had been obscured over time.  I then discovered that my multi-meter broke.  Kid-zilla and I rigged an old MRC transformer to the plantation loop, and all was well....On to this project.

       

      Today, I taught Kid-zilla how to score..

      ...snap, sand...

      ...and fit...

      ...plexigalss parts.  Usually, we stumble through the learning process together.  Today, I actually had a skill to pass on.  Yay, me! The end result looked like this:

      About where you can see the reflection of my elbow, you can see one of the fastening points for the original chassis.  Straight up from the reflected crest of the German Naval Academy, where I was once an exchange midshipman, is the other one.   I plan to exploit both to fasten the deck to the boiler/cab.  I will fasten the rear of the deck as we did Komaka Iki, with a block of wood  held to the inner tank walls with E6000 to receive wood screws coming up through the deck plate.

       

      We now had to examine the new chassis.  Of all the STAINZ in the stable, most are the old "clamshell" style. Komaka Iki has a Maerklin one, but it is apparently a bit older.  Kid-zilla took this one out to the tracks for test, and...nothing...There are two sets of pins coming out of the motor block:

      Jumping across each pair did nothing.  I thought about jumping across pins from port to starboard side, then decided against destroying a second motor  block on this project.  I'll find the diagram first!   It may be I have to get the circuit board to finish this.  Oh, well...

       

      We decided not to let the 'trons ruin our spree, so we studied how best to mount the boiler/cab to the chassis.   As you can see, the rear coupler extension will be an issue that we didn't have with Komaka Iki, who got a block of wood to serve the purpose:

      I thought about cutting the projections on the motor block flush and then cutting the coupler extension.  Cutting the new piece seemed  a bad idea, since a.) I've no confidence in my ability to cut a straight line, and b.) you can't uncut things if you screw up.  The plan, instead, is to cut holes in the deck over the triangular extensions as we did for Komaka Iki.  The simulated rods from the valve gear can then pass up through the holes that accommodate the triangles in the center. I'll get the stern to settle over the coupler extension by cutting slots to accommodate the walls of the coupler extension.  The whole lot will secure to the motorblock by tapping holes in the deckplate and using the existing screws to simply fasten the deckplate to the motor block.  At worst, I am out a piece of plexiglass.  

       

      I don't like to make major moves  on the fly when I am unsure of the direction (MIK's excepted!), so we backed off to sleep on it.  At that point, O.S. joined us for MOW work, installing railclamps on troublespots.  I had picked up ~100 second-hand on business trip to CONUS some time ago, (You don't say "No!" to SplitJaw clamps at ~70 cents each!).  Now, to find screws locally to finish the job.

       

      Errands and a beach run later, it was time to just run trains.  Kid-zilla took a perch at Deadman's Curve, the historically most troublesome part of the mainline...

      ...for an evening when European iron horses got to stretch their legs...

      Someday, I will learn how  to focus the camera on my tablet.  it'll probably be about the time I consistently remember to stop trains before photographing them!

       

      Have a great week!

       

      Eric

      Update:

       

      Blustery winds made diving impractical, so I gave over a good part of the weekend to this project.  I had measured out and sketched my cuts earlier in the week, then used a grease pencil to mark where they should go:

      While the 1:24 gang finished their coffee and got their tools, I set out some motivation, to include Oma'o and the MOW train loaded with rail clamps and tools should a break be needed:

      Most of you know I tend measure 54 times and screw it up anyway, so this time I measured a 55th time...

      ...and, as they say, 55th time is a charm!  Unfortunately, it was just a tad short , and the motor block screws didn't quite line up with the deck.  In addition, there is a bulge in the motor block lid, so the deck won't lay flat.  The gang shows our plan, which is to use some washer, a slightly longer screw, and brace the deck in place:

      Not having longer screws, I went on to some styrene work.  Somewhere along the line, I deployed rail clamps until I ran out screws.  Anyway, the "bow" and "stern" got patches.  I used piano wire left over from Diesel Dan's handrails to make the small piece of electrical conduit.  I was especially proud of that one.

        

      I have since patched the large hole over the coupler, too.  Also, I dug out the beams for the end beams.  

       

      Meanwhile, back on the lanai, E6000 served to  mount some scrap wood to the interior:

      I actually set them flush to the edge of the tank, then carefully pressed the deckplate up into the blocks to ease them to the correct height.  I even located the washers and wood screws, all left over from the cane car project of last year, to moung the boiler / cab to the deck.   At this point, I decided to let all the glue cure, put Oma'o an the MOW train on a siding, and let 'Olu'olu (Red) pull the local for the rest of the day.  Rudy Railbus wasn't having it, so "he" came off the tracks, Diesel Dan took over, and all was well...at least after "his" box car took a nose dive into a gully to deprive itself of its brake wheel, thus making it consistent in appearance with like all our other box cars.

       

      Sunday came and after church the boys and I stopped by the hardware store to look at screws and washers.  Much to the relief of the staff, we found them without mixing up too many of the drawers!  Exchange HSB engineer Hans Josef looks on as the gang installs the deck:

      The nylon washers are a tad thick, causing the boiler / cab to sit too high.  Of course, I didn't notice this until AFTER I assembled everything!

       

      I raided (with permission and oversight...I was to take nothing good or expensive!) CINCHOUSE's jewelry making supplies to find something for the valve gear.  I settled on earring posts and small beads...

      The earring posts will hold their shapes once bent, and the beads will keep the things from slipping from the rod.   Or so I hope...I will  tinker with this once I've painted the chassis flat black and effectively finished the rest of the project.

       

      I wish I could say I assembled what I had to carefully check the fit.  In fact, I assembled everything I had simply to see this loco underway, making weigh for the first time in over a year.  The 1:24 gang got into their work caboose, Hans Josef brought up steam...

      ...Kid-zilla ambled out to take the throttles...

      ....and video proof I should have started with a STAINZ chassis to begin with:

      Eric,

      I can't get your video to work.

      It doesn't look right. What does come up on my desktop is the picture of Kid-zilla at the throttle.

      @Joe:  Video has always bedeviled me.  I forgot to make sure I pasted in the right link.  I updated my original post to see if I can get it to work.

      U

      ....and video proof I should have started with a STAINZ chassis to begin with:  Video of Christmas Thomas Underway on His Own Power.

       

      We are now where we should have been in March, back when the kids still had interest in the project.  There is still some styrene work to do, end beams to make, painting to complete, coal to load, headlamp to power, signage to print (gotta get that CRICUT!), and weathering to apply, but I feel like this project is over the hump...at last...Christmas Thomas, if nothing else, will be ready for duty in December when the Christmas tree arrives on the lanai!

       

      Updates as progress merits.  

       

      Have a great week!

      Eric

      @Joe: All I managed to do is accidentally erase the end of the original post.  I reposted that paragraph above. Sorry.

      Eric,

      Tried to make sense of your link, but the onedrive link doesn't work as an embed.

      @Pete. Thanks.   I cannot remember how I did it  before...Maybe just a straight link?   Here's to trying:  Video of Christmas Thomas Underway on His Own Power.
