Log cabin, 3d printed

Ever since I 3d printed the slab siding cabin, I have been trying to figure out hoe to 3d print a regular log cabin.  I am not sure this qualifies as a regular cabin, but it works.  I wish the logs had come out a little rougher, so I will have to work on that.

 Just as a test, I drew up a 16' square cabin.  Having played with printing wood shingles, and pretty will failed, I decided this would be another chance to give it a try.

 I exploded the drawing for printing.  Note the roof ridge cap to the right.  I have not figured out how to get a wood shingle ridge cap to print right, so I went with a copper cap.

 Here is the roof with the top flattened to accept the copper cap.  Note that this is printed standing on one end, and then no support material is needed.

A screen shot of the cabin sitting on the build platform in the Afinia 3d printing software.

The roof was printed in this position.  Here is the first print during assembly.  


After priming, I painted the logs a light tan color, then dry brushed them with various grays and 
browns.

The roof was painted a dark gray, then dry brushed with light grays.  The roof cap was coated with Sophisticated Finishes Copper and weather with their weathering solution.  The rusty stove pipe was done the same way, but with Sophisticated Finishes Rusty Iron.

I think, when I get time, I will add some branch knobs to some of the logs.  

I have several project going, including another gas station, and machine shop, but those are on the back burner while I work on the Turkey Creek Division challenge model for the May meeting.

HO Auto Hauler KitBash

Somebody on one of the 1/87 scale vehicle Facebook groups posted a picture of a Road Champs Auto Hauler that they had kit bashed to use in HO scale.  As I recall, they said the had to widen the trailer, but I did not find that widening was needed.  Regardless, once I saw his kitbash, I just had to have one, so I quickly got on ebay, and picked one up.

Obviously, for my era, 1949, the tractor was not going to work, and the vehicles it was hauling went straight to the junk pile.  Actually, that junk pile, along with the tractor went up on ebay, and were out of my way in no time.

I took four Classic Metal Works (CMW) vehicles and test fit them on and in the trailer.  To my surprise, and delight, they fit like the were made for it.

I decided to pair it up with a CMW White tractor, which took some filing on the metal pin on the trailer.  But a simple conversion, none the less.

The most obvious thing to me that needed done was the ladders needed opened up.  A little time consuming, but not too hard.  I drilled a small hole in each corner, then used a hobby knife to slowly cut through the plastic.

Then I took a small square file and cleaned up the holes as best I could.

The center ladder is cut out, and it makes quite a difference

The plastic solvent welds with Methylene Chloride (Tenax, Ambroid ProWeld, etc.), but it is a little more flexible (rubber-like) than styrene like a lot of toys.

A test assembly after priming.  

I felt I needed some sort of company name on the trailer, and I only know one person that ever drove such a rig..., so now he has a transportation company. 

 There were moulded in tail lites, so I painted them yellow and red, and put a dab of gloss paint on them.  The wheels and tires came out of the junk box.

I want a red tractor with two rear axles, but I do not have one.  That will go on the list of things to buy.

Loaded and ready for delivery.

About as simple a conversion as possible.  Give it a try.

Here it is with the Classic Metal works 46-49 Ford tractor.  It is much smaller than the White tractor, and does not seem to fit as well.  I am going to hold out for the White Super Power with dual rear axles.

Statues, HO scale, 3d printed reflecting pool

So, I am at my favorite Comic and Gaming show, Hurley's Heroes,  
https://www.facebook.com/hurleysheroes, 
and I ran across some inexpensive plastic gaming figures, lots of selection at gaming shops.  

I believe these are called 25mm figures, someone will correct me if I am wrong, but they are somewhere near O scale (1:48).  Too big for my HO scale layout, and besides they are fantasy figures.

But I thought I could use them in the town square as a statue with a reflecting pool.  I chose a couple, and designed and 3d printed a base and reflecting pool.

The first attempt came out way too small.  

So, I about doubled its size, and
hollowed out the bottom to save material and print time.  Material is cheap, print time, or as Miles Hale says, "those ticks on the clock", are more important.

The large stand looks a lot better to me, so I went with that.

I primed the figures, and painted them with Sophisticated Finishes Bronze, http://www.tricoatstore.com/home.php?cat=253.  Using their coatings, you end up with real weathered bronze, or copper, or rusted metal, depending on the product you choose.

 In this case, I chose bronze.  It is hard to beat the color when it is the real thing.  Sophisticated Finishes uses "A liquid of ground bronze that creates a dark brown metallic finish. Treat with Patina Blue Antiquing Solution to oxidize into a dark blue verdigris finish." 

The statue was presented to the city by their sister city in France.  That is my story, and I am sticking to it.

An old west gun sheriff.

Grain bins, HO scale, 3d printed

Not really part of my Down on the Farm series, as they are too new for my era, nonetheless, they certainly are farm scenery.  I designed and 3d printed these as a commission for a gentleman that needed many of these for his Iowa railroad.  I had been looking for something with corrugated metal, just to see what I could come up with, and this project fit the bill.

I made several different diameters, and three different heights, along with two different types of roofs, and two types of roof vents. 

This is the drawing I ended up using for one of the designs.  Parts from different bins could be mixed and matched, as all the roofs have the same slop, so any number or combination of roof vents would work.  

Once printed, I primed them, and sanded the roof panels flat, as the layering from the printing process is quite noticeable.  I then used .020 x .020 styrene on the ridges for roof panel seams.  The roof ladder is also styrene strips.

Since I print in ABS, the styrene will solvent weld to printed items, as will the ABS printed parts.  

Probably a little over weathering on the smaller one.

Wichita Train Show 2015

This story starts on the way to the Wichita Train show, at Hobby Depot in Topeka.  Whenever I am in the area, I always stop by to see what they have.  Believe it or not, I found just what I was looking for.  I have built, well, it is mostly built, a crane tender car for an HOn30 crane.  The problem is, I don't have a crane to go with it.  I have been looking for a crane I could cut up, and make work in HOn30.  N scale cranes look to small and flimsy to be HO scale.  The HO standard gauge ones are just too big, but if I could pick one up cheap, then I could cut it down. 

So guess what I found in a junk box at Hobby Depot...just what I was looking for!  This will make for a fun project and a future blog entry.

This is a picture from the Wichita Train show.  On one of the FreeMo modules, there was the same crane that had been adapted for use in a scrap yard scene.  

Good information for me when it comes to building the cab for my HOn30 crane.

I DID NOT get builder names on most of the models pictured below, but if you know who they belong to, and let me know, I will edit this post accordingly. 

Part of the FreeMo modules.

Lots of lighting, well done.

They were not running the wing train, but I understand it was there, wish I could have seen it run.



I was not the only one taking pictures.



I really liked the track plan on this layout.  Simple...and yet two commuter trains were running.  They also had a Z scale layout.

video
I am new to video's, so we will see how these upload.  A scene of Japan, as I recall.  Just neat stuff....N scale.


Apology in order here, I had the modelers name, but cropped it out and lost it.  Help if you can.  There were two On30 modules, this being one, that were connected together.  This one featured a mine on the upper level, and this station along with a plethora of other details on the lower level.

 Just one of the scenes.

And the mine.

The other module was by Mark Fisher, see I did get one name, and it featured a logging and sawmill operation.

I also what to thank the Chisholm Trail Division of the NMRA for allowing me to present a clinic on 3d Printing at their fine event.
