Dixie Garage, Carolina Craftsman Kit

I have not been posting for over two years, and the main reason is I would rather spend time modeling than posting about it.  Therefore, don't expect any detailed descriptions, as not much time or thought is going into posts going forward. 

 The parts of the kit.

I am adding a garage door to the back wall, so I cut an opening using the front door opening as a template. 

I am using the scrap piece to fill in the old window opening.

I applied paper printed studs to the inside wall when the wall could be visible through the large doors.

The back patch came out pretty well.  As I recall, I used the rubber cement method for the pealing paint.  Dab some rubber cement on the siding before the finish coat of paint, then when the finish coat of paint is completely dry rub of the rubber cement.

I used a decal for the "GAS" sign, but all the others are printed on paper and glued to the building.

There a wood stove below the chimney, but it has obviously never been used, since the chimney is clean,

The truck cab is from Sylvan, and the bed and winch were 3D printed, as were the barrels, rusty fender compressor, gas bottles and wall fan.  The scuppers and downspouts were 3D printed using copper infused filament, and were weathered naturally using salt and ammonia. 

Thanks for looking.

Just for Giggles #9, HO details

Some odds and ends I have been working on.


I designed these for a friend. I did some simple internet research to get the standard dimensions, and then played around with some of the cross sections until I was able to get a good 3D print.

I used wood for the benches, but if you are modeling a more modern era, styrene strip painted aluminum would be more appropriate. 

Ships Boiler

I based this on a boiler for a large ship.  But then it turned out to be too large to fit on a flat car as an open load.  So I scaled it down to fit an HO scale flat car.

Drawn in SketchUp, it was easy to resize.  I broke it up into two pieces for optimum 3D printing.

Wood Water Tanks

This is a kit from Built Rite Models, a small water tower.

A nice simple one evening wood craftsman kit.  It is available in HO and O scale and could be used in any number of scenes.

Traffic cones

I did a little Internet research to get standard sizes.   I drew several different sizes in SketchUp, and

printed out a bunch of them.

A great addition to a street scene.

Mini-Lindy Kitbashes #1 & 2, Ford PU

A couple kitbashes of Mini-Lindy Ford Pickups

A shot of the two pickups, and the Packard as picked up of eBay. 

Dump Truck
A first test assembly with a dump bed I had in the parts bin.  I posted this on the 1/87 scale vehicle Facebook page for some feedback, and got just what I wanted.

I filled in the hole in the center of the hood, and 3D printed a shorter bed.

This model was missing the front grill and bumper.  I designed and 3D printed and new one. This was an early test, as I made some changes on the final assembly.

I 3D printed the frame, and made the dump bed so it would dump, although I never have found a way I liked to put a hydraulic cylinder on it.

Since the fans would be visible, I designed and printed several sizes in order to pick a size.

I fabricated the exhaust out of brass tubing.  

This model was also missing the windows, so I 3D printed a form and vacuum formed the windows.  The form is in the dump bed.

 In this view you can see the rusted exhaust manifold, another part I designed and 3D printed.

Tow/Boom Truck

I wanted to turn the other truck into a two truck.  In order to design the bed, I took straight on pictures of the truck, uploaded the pictures into SketchUp, and sized the pictures to scale.  

I drew the basic design right over the photographs to get the correct curves and dimensions.

On this one, I closed in the entire top of the hood.

I also designed and printed the boom and headache rack.  

I scratch built the winches

HOn18 Mine Cars, HO on Z scale track

I designed an HOn18 engine sometime back.  The shell fits over a MicroTrains mechanism.  Link to blog entry on the engine.

These little cars were inspired by George at Show Me Lines Trains in Grandview, MO.  He showed me a picture of a side dump car, and wanted to know if I could design and 3D print something similar? 
My first thought was, well yes, but not with my home printer, but then, I came up with some ideas to try.  One of the good things about having a home printer, is that the failures don't cost much, and now I have a lot of junk for around the mine site.  I tried more designs than I can count, most worked to some degree, but others were complete failures.  Here are a few, but not all of the different designs I tried.
 I decided early on to use Micro-Trains Z scale Arch Bar trucks as the standard to design around, and also use their Z scale couplers.  These could also be push carts, particularly in S and O scale, and then have no need for a coupler.  You will notice that the design closest to the from, has no bottom.  I designed it so that I could put a piece of brass bar in the floor to add some weight.

 Once I figured out the dimensions and shape needed to fit the trucks and couplers, I took those designs and started trying other options using the original base.

 I used .030 styrene for the connector between the tipper and the rest of the car, and thus the tippers will actually tip, as long as you only glue the styrene rod at one end.

  I am sure there are many more possibilities, and I am sure I will come back and do more in the future.

 As I mentioned above, it took several redesigns to get the trucks to fit properly.  

 Here are several early attempts.  I am never going to get a completely clean angle with and FDM printer, but it only took a little filing to get it looking reasonable.

 This kind of give you an idea of how many failures I had, just getting a square box on wheels.

 This is a good example of the layering making the item, in my opinion, unacceptable.  Note the layering on the corner boards.  It makes the "grain" run the wrong direction, horizontally, rather than vertical.  In subsequent designs, I left off the corner boards, and added styrene strips.  

A couple of things to note.  The bottom gondola has had the brass bar inserted for weight.  Also, the corner boards on these gondolas are styrene strip, which looks much better than the printed vertical boards.  The side dump cars, several different versions, various stages of completion, natural ABS, and primed.

I painted the side dump cars with Sophisticated Finishes Rusting paint.  The gondolas were painted a wood color then a wash of India Ink and Alcohol.  

The trucks were installed using the Micro-Trains pin provided with the trucks.  As I recall, I used the 2-56 tap drill size as the hole for the pin, and it worked great (there does seem to be some variation in the pin diameter).  The couplers were installed using the screws provided with them.

Here is a shot of the engine and cars sitting on some Micro-Trains Z scale track, a penny to the right for scale reference.  Again, these could also be used in S and O scale for push carts.
