Portable Hog House, Feeder, & Wallow, Down on the Farm #10

I really need to get back to work on this, as it was supposed to be done for the June Turkey Creek NMRA Division meeting, doubt I will get the diorama completed, but if I can make the meeting, I will take what I have.

That was written in early June, and I ended up not getting it done, obviously as one can see by this post.  I also ended up not being able to attend the meeting due to a business meeting,

A couple structures that I am building from strip wood are the portable hog houses and the hog feeders.  The plans for all three structures in this post came from the South Dakota State University web site, and are era appropriate for my 1949 era model railroad.
The plans for the portable hog feeder.

The pile of strip wood, stained with India Ink and alcohol.  I pre-cut the wood to length before I stained it.  I glued them together with yellow wood glue.

And here are the plans for the portable hog house.  There are three versions shown, I opted for the half open front model.

I used sheet wood for the sides and the doors and some strip wood bracing.  I used roofing from Wild West Models.

A few shots of the the finished structures.  I used some 3d printed scraps for the hinges and the door handle on the shed.  For hinges on the feeder, I used strips of paper. 

Yeah, I have not painted the pigs yet, of put them in a pen.  At this point they are free range hogs.  I will be adding scale corn cobs to the feeders and corn crib.

I know almost nothing about farming, so I thought it odd to have a concrete hog wallow, but it gave me something else to print, so I thought I would include one in the scene.  

Here is the mini-scene with a lot of work to go.  I need to add piping from the windmill to the hog wallow, and from the wallow drain to the creek.  Also water in the wallow.

Obviously I am running behind in my posts, too much work, some volunteer work on the National Narrow Gauge Convention coming up in a few weeks, and a general lack of time and motivation.

Maker Faire KC 2014 Highlights

At least for me, these were the highlights.  I was asked to display some of the items I 3d printed by the model railroad group that runs the displays at the station, in particular, Louis Siebel.  I want to thank him for inviting me.  There are lots of children in attendance, so I did have a couple do not touch signs up.

Here are a few of the things I displayed.

I also had the printer running both days, and, because people need to touch something, I included a tray of 3d printed things that can be touched. 

I also brought a diorama that is mostly items I had printed at, the small engine repair shop, more pics here:

I really thought more people would laugh at the inside joke on this model, but alas, I only saw two people laugh on Saturday.  Sunday, however, was better, as about 10 people caught on.  If you don't get it, you didn't watch Breaking Bad.  The original post with details on building this project are at:

I displayed my 3d printed forklifts,, and happen to be printing one when  Steve (Reverend Hearse) came by the table.  

He was a builder of model vehicles, and wanted to know if I sold the items.  I told him that I had one printing, and if he would come back in an hour, I would fix him up.

This is what I handed Steve, no charge.  I had actually never assembled the lift portion, in fact, I had never printed it on my printer before.  The one I built was scratch built with styrene strips.  

He showed up at my table the next day with the prototype done, or close to done.  I had not made a good way to attach the lift rack to the front of the tractor, which it the reason you build a prototype.  

Not bad for an overnight project and no instructions!

Make Magazine had a nice booth.  Make does a great job covering the home based 3d printing market.

Iron Man showed up along with whoever the other guy was...?

The Sedgewick 3d SLA printer, a kit made here is KC, as showing their printer, and taking orders.  

Check this out, a summer project by a couple young men, building a 3d printer from scratch.  

I really made a mes of my modeling area getting everything ready for the Turkey Creek build challenge, and the Maker Faire.  Then I ended up having a business conflict and not making it to the Turkey Creek meeting.  I have spent the last two weekends just cleaning up the mess, but I did get a lot of drawing done on the next 3d printing project, the Chilhowee State Bank in Chilhowee, MO.

So this is the next big project I am working on.

Barrels, Wood and Steel, HO, S, and O Scale, 3d printed

I will be giving away 3d printed barrels to any model railroader who stops by my table at the Maker Faire KC this weekend.  Table 129.  I have both wood and steel in HO, S and O scale.  

 Most of the time, I prime the ABS, as it is porous from the printing process.  Here are all three scales, and both wood and steel.  I print four at a time, just to keep the cycle time down, and two open and two closed in each group.

O (1/48) scale, as I finished them. 

 S (1/64) scale

HO (1/87) scale

You can click on the pictures, and see a higher resolution, close up picture.  Then you can see the flaws in the FDM printing process.  However, at normal viewing distance, for scenic items, they look fine for most purposes.  I would not want to use this process for printing motive power or for vehicles.  For that I would want an SLA printer at the very least.

Stone Arch Bridges, 3d printed, Down on the Farm 10

I saw some pictures of stone bridges, and thought it would be a good learning project for 3d printing.  Here are the two bridges I have done so far.

The back one was just to see if I could get something acceptable, and the front one I am using on my hog farm diorama.  I still don't know where I will use the back one. 

Here is a picture I uploaded in to SketchUp, then I scaled the picture to something reasonable, and used those dimensions to draw the bridge.  

The bridge had to be split in four pieces for printing.  

To get even a quarter of the bridge to fit on the printer, it has to be oriented at 45 degrees on the printer table.  This is a screen shot of the printer software showing a section of the bridge ready for printing.

I added texture to the surface of the rocks by mixing Aleene's Tacky glue to the paint.  That filled in any imperfections in the printed surface, gave the rocks some uneven surfaces, and put some color on at the same time.  The top course of stone was printed separate from the rest to adjust the width to fit the track ties.  I used Micro-Engineering bridge track, but won't add the guard rails until it is installed on a layout.

Down on the Farm #10
I have not been working on my hog farm diorama for some time, and really planned on having it done this week.  Some family things got in the way, but I still hope to have at least the buildings placed for next weekends KC Maker Faire (  I will have a table there displaying many of the items I have 3d printed.  I decided add train tracks to the farm, and since there is a stream through the farm, I was going to need short bridge over said stream.  
Knowing the stream width, I designed a bridge to fit the space.  I decided to add a cut stone with the railroad name to the face of the bridge.  Because the bridge is so small, I did not bother with rock detail under the arch, as it will not be seen.  Also the large bridge above is two sided, so it can be viewed from either side.  This one, because I think I know where it is going on the eventual layout, only needed details on one side.

Here is a screen shot of the Afinia printer software, with the bridge positioned on the printer table.  

The finished bridge except for installation in the diorama.  I added texture to the rock faces by mixing some sand in to some Aleene's Tacky glue.  I looks okay, but if it were a foreground model, it would be marginal.  

A little better shot of the cut stone lettering, and the texture.  The texture would have been better if I had used finer sand.  Next time!

Barry Well, 3d printing and Vac-U-Forming meet in HO scale.

This picture of the Barry well was posted on one of the Kansas City Facebook groups.  The Barry Well was located only a few miles from where I now live, and I thought it would be a nice model that I could use some place either in a diorama or on a layout.

This photo was posted by Gary Brenner in the Kansas City Memories...Vintage Photos, Places and Things Remembered Facebook group.

This was a hand dug well dating back to the time of the Oregon Trail.  It is said that it was one days trip by Oxen team from Liberty Landing.  

Liberty Landing was about where hwy 291 crosses the Missouri River, and Barry was located about at what is now hwy 169 and Barry Rd.  According to my calculations, that would be about 12 miles.

I drew the well in SketchUp to 3d Print most of the parts in HO, 1/87th, scale.

Once drawn as a complete structure, I explode and orient the parts for printing on the Afinia printer.  

The roofing was another matter.  I decided to go old-school, and break out the 1962 era Vac-U-Form to make the tile roofing.  For more on the Vac-U-Form, see this link for a previous post on who I used it and what I have learned so far.

I did some tests, including this one with the canoe.  The patterns for the tile and the canoe were 3d printed and also drawing in SketchUp.

I cut the formed tile in to strips, and glued it to cardboard for the roof.  

The ridge cap is also Vac-U-Formed, but is individual pieces.  

I am not sure what I am going to do with it, but it was a fun, quick project.

I have to get back to work on the Down on the Farm series, and I have a few more posts to do to finish up the structures on that diorama, so hopefully, I will get motivated to get that done in the next few weeks.  Scenery just ain't my thing!
