More "N" Scale, or Just for Giggles #7

Since I don't model in N Scale, I only do items in N Scale for when it fits my time.  Fred Miller ask me if I could make Teepee's for a Teepee Motel.  I figured, why not give it a try.

\
Fred supplied me with several prototype pictures,

and I dropped them into SketchUp.  Only the door took any real time.

Here is the teepee, still sitting on the printer.

A little clean up.

Fred Miller took all these finished pictures of the module he built.   

Just darn cool.

The trading post is a Blairline kit, http://www.blairline.com/tourist/

Nice sign.

Thanks to Fred Miller for allowing me to share these pictures.

The complete module, check out the cool road.


Outside entrance stairs
At a show, I was selling the HO version of these, outside-entrance-stairs-for-ho-scale, and a gentleman asked it I could make them in N scale.  I figured I would give it a try, and he said he would pick up a couple from me at a show in Springfield, MO.

The guy never showed up, but I sold all the stairs I had with me.

Concrete tilt up wall
I had a local N scaler contact me about the possibility of making sections of concrete tilt up walls.  

He had drawings to work from, so it was pretty straight forward.

You would need several to build a building of any size.  Certainly easier that glueing up styrene.

About the only other things I have done in N scale can be seen here, n-scale-or-just-for-giggles-3

Chainsaws update, 3d printed in HO, O, S and N scale

I posted about the 3D printed chainsaws preciously, http://nvrr49.blogspot.com/2015/05/chain-saws-ho-scale-3d-printed.html, but I have since added S and O scale sets.  I also added to the HO scale set.

This is a picture of some of the HO scale set.  These were printed at Shapeways, and printed in FUD, Frosted Ultra Detail.

I tried to keep the costs down, so the HO scale set has more pieces than the S or O scale sets.  This is the drawing for the HO scale set.  Seven complete chainsaws, and four extra motors.

This is the original set, in HO scale, as it came from Shapeways.

This view shows, from left to right, N, HO, S and O scale.  Once cleaned up, the Frosted Ultra Detail material tends to turn white.  Note that the blade on one of the O scale saws broke off, easily glued back on.  The HO scale saws are available for sale at Shapeways at this line, chainsaws-group-2-ho-scale.

The S scale set is a available at: \chainsaws-group-2-s-scale.

The O scale saws are available at: chainsaws-group-2-o-scale

The N scale saw, which Shapeways says they will not print again due to their fragility.  They are crazy small.

Construction Vehicles, Road Roller, Road Grader, Payloader

The latest line up of HO scale construction vehicles I have built.  The road graders are metal toys that I updated and weathered a little.  The road rollers are and the small bucket loaders are mostly 3D printed on a home printer, an Afinia, and are based on prototypes.



Payloader, little bucket
I designed the these Payloaders based on a single photograph.  

They are a little small for printing at home, but with a little work, they are, in my opinion, acceptable, if you hide them a little.

I designed it without the hydraulic cylinders, but with a place to mount them.  Although, the parts are so small, they did not form well.

To avoid ridiculous amounts of support material, I exploded the drawing into a printable form.

I lot of little pieces to glue together, but not too hard.

I used brass tube and wire for the hydraulic cylinders.

Road Roller
I ran into a 1940's road roller at a gas station.  It was on its way to the scrap yard, so I am pretty sure these are the last pictures ever taken of this machine.  I also ran into a second old machine, the one pictured with the tires still in place, in my travels.

I designed most of this while showing my 3D printed items at the Worlds Greatest Hobby Show when it was here in Kansas City.  By the way, LOTS of young people at that show.  All the people that say the model Railroad Hobby is dying, were not at that show,

I generally draw the finished, assembled item I am planning on printing, then I decide how to explode it for optimal printing.  In this case, I felt the only acceptable way to make the rollers, was to use 7/16" brass tube, so I only printed the end plugs.

I started doing test prints at the show, and by the time I made all the adjustments, reprints, redesigns, etc., I had most of the parts for four road roller, so I gave one away, and built three.

The wheels, tires, and mounting system were all printed separately, for various reasons, but if nothing else, it made them easier to print.  The mount has a pin on it, and the wheels have a dent, to they would align.

As I assembled them, I tried different ideas on the rollers, as the printed center axle did not look too good.  In the end, I feel the best option was printing a hole, and then inserting a styrene axle.  They are NOT made to turn, they are just for looks, but the axle on the front wheel is out in the open.

I generally prime all my 3D printed models.  I did paint each of these with a different type and color of paint, just to see what I liked best.  

I reality, just about any paint will work.  I have yet to have one fail on the primed ABS.  

A few bits of wire, and some scraps of styrene for the pedals, and they are ready to go to work.

Road Graders
These are metal toys that I picked up a various trains shows.  The orange one is a newer, slightly less detailed version.  The yellow one, is a Mercury Lil' Toy.  I arrived missing some tires, and had been played with hard.

The orange one was in pretty good shape, only a few nicks, so I applied a little weathering to the nicks.  The main issue was the blob they called a steering wheel.  I finally decided the only option was to cut it off and replace it.

I replaced the steering wheel with one I 3D printed.  

I also 3D printed an air clearer for this model, and added foot pedals and a gear shift.  I also designed and 3D printed the tires.  

The yellow model was sandblasted to remove all the only paint, and then painted with Krylon old Caterpillar Yellow.  
I don't care for the yellow wheels on the orange model, but with some weathering, at least they are not shiny. 

I have since found another road grader, and it not only needs tires, but the grader part as well.  More items to design and 3D print.

Wall details, 3D printed in HO scale

For custom details, Shapeways is the way to go.  This assortment is all wall details.  Some of these I had printed before, others, this is the first time.  The set includes a lot of parts.

 There are two different gas meters, two of each.

A selection of pipes to run along the walls. 

 Four different wall vents, four of each.  Three of them are see through, the four smallest are surface mount.

 Four wall fans, and two types of electric meters, four of each.  

 Roof drain scuppers.

Two types, eight of each.  Four coal doors, a set of six mail boxes )note the raised lettering for the apartments).  There are also two size of fire sprinkler connections, four of each.  I have since added four alarm bells to put on the outside wall of the building.

There is a large selection of tension rod washers (sometimes called stars).  Nine styles, eight of each.

Here are a few pictures of the tension rod washers.  These are based on prototype pictures, and are used on most older masonry buildings.  These are HO scale, so the are between 1/8" and 1/4" in size.





There are eight of each of the tension rod washers in the set. 

Here is one installed on a building, an old Roundhouse kit.

 The smaller gas meter, and the piping. 

Here is an example of how I used the pipe, and you can also see more of the tension washers.

 Here are the larger gas meter, and four wall mount fans.  

 At the top of the picture  are the fire alarm bells and the eight fire hose connections.  Next down is the apartment mail boxes with raise lettering. And, at the bottom are the scupper (flat roof downspout drain), two styles.

Here is another shot of the mail boxes and fire apparatus.  To the right are eight electric meters, four of two different styles.  The connections can easily be filed off if needed.  

The electric meters installed on an apartment building.

The mail boxes.

Sixteen vents, four sizes.  The small vents to the right are surface mount, the rest are see through, i.e. real vents. You can see the copper penny through the vents.  The coal doors are in the upper right.

I held the larger vent up to the light for this picture.  One has to be very careful to not fill the vents up when painting.

I added a coal door to this apartment building.

I did not expect to ever sell the piano store, it was just something I wanted, but I have sold a couple sets, https://www.shapeways.com/piano-store-stock

Here are some links to other details I have designed and had printed at Shapeways.
