Video of Machine Shop

A couple of short videos of the machine shop.  I gave it a spin on a turntable.  Construction of the building, which is 3D printed on a home printer, can be seen here.  Since the video upload to Blogger is so poor, here is a link to it on Youtube,

Most of the interior details I designed for printing at Shapeways.  The design details were covered in several posts last year.  The first covered the Metal Shaper and the Bandsaws.  The second instalment covered the Large Lathe, Vertical Milling Machine, Air Compressor and Bench Grinder.  The third post covered the Surface Grinder, Horizontal Mill, Drill Presses and Welding Tanks.  And here is a Youtube link for the interior video,

The details from Shapeways can be purchased at:  The set includes a smaller lathe that is not in this shop.

3d Printed, Arch Roof, Clear side walls, Machine Shop.

Although this building has a full interior, this post will mostly cover the structure.  The building was printed on my Afinia H479 printer in ABS.  I designed it in SketchUp and sized the openings to fit Tichy windows and doors.  HO scale.

I designed the machine shop tools a year ago, and had them printed at Shapeways.  I posted about them in three previous posts.

Part one: Metal Shaper, Bandsaws
Part two: Large Lathe, Vertical Milling Machine, Air Compressor, Bench Grinder
Part three: Surface Grinder, Horizontal Mill, Drill Presses, Welding tanks

 Here are all the parts, as originally drawn.  I designed the upper side walls, and the gable ends to be printed in transparent filament.  It is marketed as clear, but it certainly is not.  I does work great for glass blocks, spiral-chimney-glass-blocks and memphis-store-front-3d-printed-glass-blocks

There are always things that I would do different if I were to do it again.  If I were to print the end panels again, I would add the support material shown in the drawing on the left, to give the panels a cleaner edges on the lower curved edges.  The picture on the right shows how I printed the ends I used.  If you look closely, you can see the rough edges.

The roof parts, painted and ready to assemble.

I would say that I am test fitting the roof on the walls, but you can probably figure that out on your own.

The roof and walls are printed in natural ABS, primed and painted, the roof silver and the walls gray.

Test fitting the Tichy Windows.  Both Grandt Line and Tichy have good web sites, where they show all the openings needed for the windows they offer.

 I had not originally planned on making a diorama, but I decided to in the end, adding a welding table out front, and a storage rack.  The storage rack was 3D printed on my printer.  The material on the rack is from the junk bin.  Mostly left over shapes from wood car kits, where I replaced the wood shapes with styrene.  

The diorama base was also needed for protection for the windows, if was was going to have any of them open.

I did add a minimal interior to the office, but unless I stick some lighting in it, it is barely noticeable. Both the rolltop desk and the chair were 3D printed in wood, so no finishing was needed. 

 I added some angle around the roof, so it would fit tight on the building. 

I am sure I forgot something, but this post is getting way to long, so I will end it here.  I prefer to spend my time modeling, versus writing about it.  I have 23 posts in various stages of editing.  Back to modeling.

2016 Turkey Creek Build Challenge entry, Larry & Steve's Quality Automotive, part 2

In case you missed part 1, where I cover construction of the main building, 2016-turkey-creek-build-challenge-entry

A lot of scenic items and the small building were from the Woodland Scenics Smiley's Tow Service.
The parts in the Woodland Scenics kit.

 The diorama is about 12" square. The posts were cut from dowell stock, and the horizontal boards are from the Woodland Scenics kit.  I drilled holes of each post, to they are installed solid.  I used whatever I had laying around for the fence.  

 I had never used static grass before, but I was not going to spend a ton of money on a grasser.  I built mine using instructions by Ken Patterson.  Here is a link to his video,

 I am not good with electronics, so if I can make one, any one can. The parts I bought to the left and the leftover parts for use someday for something to the right.

Here is the finished grasser.

Some examples of the applied grass.

I used several different brands of grass.  Whatever was available at the LHS.

I cut the souped up engines out of some old Hot Wheels I picked up at a flea market for 50 cents, and set them in the parking lot, as though they had just been delivered.

Larry and Steve are converting the old junk yard into a speed shop.  

 Larry and Steve have started fixing things up, a new sign, a new roof on the office, and replacing the bad boards in the fence.

 A view from the back, shows the patchwork fence still in place there.

 Details came from the Woodland Scenics kit, the junk box, and I 3D printed some.

 The vehicles, well the ones that are not junk, are from CMW.  The flatbed on the red truck is 3d printed, including the wood bed.  Here is a link to a blog entry I did on 3d printing with wood infused filament, 3d-printing-with-wood-wood-infused-pla

I circled a few of the items that I designed and 3D printed.  As mentioned in the previous installment, the roof ridge cap was printed in copper.  I have a couple of blog posts on 3D printing with copper, 3d-printing-in-copper part 1 and 3d-printing-in-copper-2-3-weathering.  The Chimney was also 3D printed.  In the front corner of the fence is a pile of copper scrap.  This is scrap from printing in copper, and I ground up the scrap in a blender before weathering it.  The gate, including the corrugated metal were also 3D printed.  To the left are the four truck bodies I designed and printed, including the trash truck body.  Two the car frames were printed, and the one mostly buried in grass came with the Woodland Scenics kit.  The two big wheels, pole road engine wheels, the large tires next to the trash truck, and the fan blade were also printed, as was the yellow car body in the near corner.

2016 Turkey Creek Build Challenge entry, Larry & Steve's Quality Automotive, part 1

The main building was part of the 2016 Turkey Creek Build Challenge.  This was a kit put together by a team of Turkey Creek members, and the wood was cut out on a CriCut.

When I started writing this post, I assumed I would be able to cover this diorama in one article, but it just drug on too long, so there will be two entries, one on the main building, and one on the rest of the diorama.

The plans, as seen above, and below, were drawn by a Turkey Creek member.  All the parts are shown above, including the Grandt Line windows.

A close up of the plans (as if you did not know that).  I changed the kit slightly, by adding a garage door on the front.

The wood cut on the CriCut is quite then, so they recommend a lot of bracing.  One cannot have too many clamps.

I weathered the outside with Alcohol and India Ink (A and I), and painted the interior with flat black.

I painted the fenestration wood color, and then slopped on some A and I, as can be seen on the items at the top of the picture.

Rather than using strip wood for the roof framing, I 3D printed the roof framing.  Above is the drawing in SketchUp.

This is the view on the computer of one side of the main roof loaded into the printer software.

A short video or the rafters being printed.

I solvent welded the two halves together with Methylene Chloride.  Since I generally print in ABS, Methylene Chloride works great.

For the stairway roof, I used cardstock, and then

covered it with roll roofing.  This roll roofing was left over from last years Turkey Creek kit.

I dabbed on some rubber cement, then brushed on some paint.  Peeling off the rubber cement, give a peeled paint look.  I dry brushed the doors and windows. 

I used real wood shingles.  The is cherry veneer, and it is available at most craft stores.  I picked this up at Jo-Ann Fabrics.

 I cut the veneer into various width strips, and glued them to black construction paper.

I then cut the rows of shingles 1/4" long.  I glued them to cardstock I attached to the rafters. 

I designed a ridge cap, and 3D printed it in Copper infused PLA. (more on Copper infused PLA can be seen at 3d-printing-in-copper and more at 3d-printing-in-copper-2-3-weathering.)  

I also used A and I to weather the shingles.  Note that I left a little gap between the shingles and let a little black show through.

Larry and Steve just bought the place, and are in the process of fixing things up, turning the salvage yard into a Hot Rod shop.

A couple new engines in the parking lot.  

A view of the finished roof.  

In a future installment, I will cover construction of the rest of diorama.
