OK FOLKS, here is Part deux of my update on what’s new in with my model RR progress, and more! Who else is finding lots of spare time to work on your layout and hobbies?

C&O Canal Bridges

I scaled and printed some blueprints of the three bridges across the C&O Canal on the Georgetown Branch. These were printed and had been laying around for the last couple years. I finally got some time and made mock ups using foam core and 3M spray adhesive. The goal is to get as prototypically accurate as possible when recreating the bridges, but I know some selective compression will be necessary, as I simply do not have the space. I have already done a virtual mock-up, and in the near future I hope to do a physical one.

Bethesda Update

A lot going on in this area of the layout as I completed the backdrop, painted it and removed tracks to do mock-ups.

The three turnouts are sized as follows from right to left: #8 40″ outside radius, 30″ inside radius, #8 50″/35″, #8 60″/40″, and #10 60″/46″.

Modeling Update

I have also been busy with various modeling tasks. A couple years ago I bought a large lot of HO scale vehicles, mostly die cast, some resin. In retrospect, I think I bit off more than I can chew and what I purchased are models that are going to take a lot of work to get where I want them for the layout. I’ve been prototype research on the vehicles in the hopes I can do some better paint jobs than the previous owner did. Here is one example:

After consulting with my model RR Club, the consensus is they are Wiseman Model Services (ex Walker Motor Works) International KB-11 trucks. These models were made back in the 70s, I believe, and have gone through various iterations over the years. They are made up of several parts, are really fragile and don’t have a ton of detail. I did some research and decided to try some Super Clean for stripping these metal frames. The results were fantastic. Not only did the cleaner strip the paint, it also dissolves the glue after a few days, which allows me to get the models back into their parts form for reassembly and detailing.

For reassembly, I’ve been using the ZAP PT-36 Z-Poxy Quick-Shot 5-Minute Epoxy. This stuff is fantastic, old-school epoxy. Squirt out a bit from both tubes, mix and apply. The VERY nice thing, for this application, is that being 5-min epoxy means that it’s just enough and it gets just tacky enough to allow for me to put the truck cab parts together and rearrange them carefully as I go, until I’m satisfied, at which point it hardens. Once set, it’s rock-hard. I find that with CA, you kind of set it and forget it, with little room for adjustment as you fit things together. I ordered some BSI Insta-Set to help with getting the CA to cure quicker where I need it to.

Airbrush Tune-Up – About a year ago I did an overhaul on my old Badger airbrush. I took it apart and checked all of the parts. Cleaned everything carefully and reassembled it. I decided to add a regulator to the compressor. I noticed a bit of a clunk when operating the compressor under load, so I took it apart. Inspected all of the gaskets and parts and found no issues. I reassembled it and adjusted the bleed valve. A friend from my model RR club, Greg (who you have seen here before) gave me his old air tank which I will press into service soon. I need to figure out what piping/tubing I will need. I have also been upgrading my paint supply with some proper thinners, new paint and other goodies.

Testors 1:72 Stuka Model Wrap-Up – Another interest I have is military aircraft and armor modeling. I have many unfinished projects, but this one has been floating around my workbench for about 12 years. I decided it was time to wrap it up.

Hope you enjoyed these updates. I know it’s just a lot of rambling, but it feels great to make some progress on all these things. There are so many other items I’ve checked off lately, and really the layout room is coming back alive after being dormant for about a year. I am reinvigorated to get moving and hope to have more updates later this month. Anyone else out there getting stuff done these days? Sound off in the comments.

I figured it’s been a long time since an update on my layout & modeling progress, so here goes, in two parts. Like so many right now, I have been productive with my hobbies. I’ve chosen to spend time in the basement getting back into the layout construction and finishing up some old projects. It’s been a lot of fun, and hard work. Here’s a [long] report of what I’ve been up to:

Rock Creek Trestle

I got the plans to place I was satisfied with and decided to start doing some work. *A quick note about this – I ended up spending another few days modifying the plans because I wasn’t pleased with them. More on this later!

I ordered the lumber a few months back from Mt. Albert Scale Lumber (FastTracks) and Northeastern Scale Lumber and decided to laser cut some jigs for the bridge ties. I even picked up some tie plates, spikes and joint bars from the folks at Proto:87, which I will use to detail the bridge track.

Next up was the stain. I did some testing with about 5-6 different Hunterline Weathering Mix stains and eventually settled on Tie Brown with a bit of Driftwood mixed in.

Fast forward a couple months and I’m picking back up where I left off with this project. I was doing a mental and physical inventory of the trestle project to get back on track. As I started to go through my notes and compare them with what lumber I purchased last Winter, I realized I screwed up. I missed a few things in my order. Oops! A quick trip to FastTracks’ website and the order was in.

So now that I am waiting for that material to show up, let’s get busy staining the wood we DO have! But how do you stain 2′ long x 1/8″ pieces of wood? I had to figure out a solution, so I designed a trough out of foil, but that failed catastrophically. (Cleaning up stain is NO FUN.) I cut a rigid paper tube in half, lined it with foil and used some old clay to create ends that are adjustable. I then laid a sheet of plastic wrap in and held it in place with clay blobs. The whole thing was rubber-banded to a piece of wood to keep it steady. This gave me a nice place to hold the stain while I dipped wood in and set to dry on drying racks I made from old Snap-Track. In the future, I may try to get some Flex Seal to spray on the tin foil and make it a bit more robust, as I worried the tweezers or the wood itself could poke a hole in the saran wrap and cause a leak.

Tichy makes a 40′ plate girder bridge flatcar kit load, that is a very close approximation of the same sort of bridge span across Rock Creek. The major difference is that this one is 1’6″ taller than the B&O prototype.

Story time. I spent a good while putting this post together, and when I got to this point, I stopped and realized there was a problem. I sat looking at the open deck girder bridge model and realized it looked a bit tall to me. I quickly opened up my drawings and reference materials and looked a the B&O plans. They clearly indicate that the trestle is to be 40′ long, 6′ 6″ wide (girder to girder) and 4′ 6″ high. This Tichy kit is 6′ tall. I then went down the rabbit hole for several hours while I tried to figure out what to do.

I opened up the plans I had drawn and started to modify the sections where this 6′ tall center span would sit. I had to lower the bents and adjust all the cross bracing in those areas. I did not like it. Some of it looked a bit odd and threw the whole thing off. I was not happy. I decided to keep digging.

Months ago, when searching for a deck girder bridge for my model, I had a very hard time finding a nice 40′ long kit in HO scale. The Tichy kit really fit the bill, but I didn’t pay close attention to the height of the girders. Micro Engineering makes a 30′, and a 50′ bridge, but not a 40′ one. The 50′ bridge is just over 6 scale feet tall. Just like the 40′ Tichy model I already have. The 30′ bridge, albeit too short, is a scale 4′ tall. I have decided that this will be my way forward. I feel that a scale 6″ is easier to forgive and blend versus a scale 1’6″ which is quite a bit more and really changes the characteristics of an iconic part of the structure. Now, some will say “there are only a small handful of people in the world who will know the difference. Who cares!?” Well, being that I’m making this model for me, and I care, I am going to spend the time to do the best job I can. I’m already knee deep!

So I then set out to RE-adjust the plans for the trestle, now with this 4′ high girder. I will have to kitbash two kits into a 40′ span, but that shouldn’t be too difficult. I’m going to add slightly taller blocks under the bridge to add to the height just a couple more inches, to hide the disparity between the prototype and my model. In the end, we’re talking a few inches difference. As I went through the plans, I realized some other errors I had made, and I cleaned them all up. I also reformatted the plans to fit on 8.5×11 paper, so I can print at home, since I think I will be in it for the long haul. I will share my progress on the plans soon in a future post.

So, phew! This was a doozy. In a long period of time, not a lot has happened, but such is my life. I have been busy with other projects… *ahem*

So, yeah. Been a lot going on. Second update coming SOON!
