SOME QUICK IDENTIFIERS THAT INDICATE THE SUITABILITY AND SCALABILITY
OF TOY VEHICLES AS REFERENCES FOR REAL VEHICLE BUILDS.
PROBABLY THE MOST IMPORTANT IDENTIFIER: “THIS TOY MADE FOR 6-INCH FIGURES.”
TRANSLATION: This vehicle is scaled for 1:12 One-inch on the toy
vehicle equals 12-inches in full scale.
A 6-inch figure equals a 6-feet tall human. (1”=12”) (1”=1’) (6”=6’)
By making a toy vehicle accommodate 6-inch figures, the dimensions and
scale of the toy vehicle have been forced to conform around the
dimensions and scale of a 6’ tall human.
The scales of the human figure and the toy vehicle are equal and scalable.
Thus the combination of equally scaled toy figure and toy vehicle mean
that the toy vehicle is fully scalable to 1:1 into a real world
full-sized vehicle and that a (1:1) 6-‘ tall human would be able to
fit into it. Even though the toy vehicle is usually significantly
skewed, the dimensions that accommodate the 6-inch figure are not. The
possibilities related to this when fully grasped are breath taking.
The human form exists in near perfect dimensional reality surrounded
by equally scaled abstract skewing. A very useful concept.
Once the principles of this concept are fully grasped, one could
easily extrapolate to other similar figure to vehicle relationships.
12” tall GI JOE figures in 1:6 scale Navy Seal dune buggy (sandrail).
12” tall Batman figures in 1:6 scale Tumbler.
3” tall plastic figures in 1:24 scale vehicles.
2.88” tall Batman figure in 1:25 scale B v S DOJ Batmobile vertigo

TWO VARIABLE 3D PICTORIAL ANALYSIS
A fancy description for comparing and contrasting two models in the same scale.
In this case I used two 1:25 scale models. One a Dodge Ram pickup truck and the other a Mobieus B v S DOJ Batmobile. Unlike using photographic images which are 2D, flat, and untouchable in 3D reality the 3D models can be experienced in 3D, rotated, and touched. A very intuitive way to reveal, compare, and contrast attributes of each and between the two. vertigo

hello everyone,
I have a attached 7 images of the B v S DOJ Batmobile suitable for re-sizing and skewing.
Most computers come with PAINT so you could use this to experiment with the images.
Down load the images.
Click on the image and select edit.
Once in go to resize the image.
Deselect: maintain aspect ratio
This will allow you to resize the image on the horizontal and vertical with each of them independent of the other.
This is an excellent way to see how the Batmobile would look in a different aspect ratios.
Example the movie correct Batmobile is 12 feet wide and 21 feet long.
Want to see how it would look street legal at 8-1/2 feet wide? Extra long or less length? Made taller or shorter?
A few clicks and you're there. I have included complete images and images without the tires. (Body only).
This way you can manipulate the body without the interference of the tires.
You could also do the same thing with Photoshop or virtually any other photo edit program as they all have image re-sizing and aspect ratio programing. vertigo

CNC vs 3DP
Chris Fox
“Now that 3D printers have emerged as the tool-of-choice for many
makers and educators, there seems to be a line drawn in the sand
between CNC and additive manufacturing. Many manufacturers even worry
that 3D printing may one day replace traditional manufacturing in the
form of at-home production (perhaps sooner than we think).
While these concerns are somewhat legitimized by a quickly emerging
market for 3D printing, the gap between printed parts and components
that are truly usable is still massive. Some would argue that the
biggest hindrance to at-home manufacturing is simply cost (which is
quickly diminishing), but as most CNC users would agree, it is much
more than that.
The rhetoric in the 3D printing versus CNC debate is often centered on
quality and cost, but this is where machines like Tormach’s PCNC 1100,
PCNC 770, 15L Slant-PRO, PSG 612, carve their place into the
marketplace. 3D printers, like the MakerBot, Lulzbot, and Form1, are
fairly inexpensive ($3,800, $2,200, and $3,300, respectively), but
many users don’t have a full comprehension of a 3D printer’s
capabilities. Printers that are capable of the fantastic imagery that
is touted in the marketing campaigns can cost upwards of $15,000 to
$750,000, or more. 3D printers are certainly capable of great things
(including metal component production), but not on a budget – direct
metal laser sintering (DMLS) machines can cost upwards of $1M. While
the newfound fanfare for this technology is helping it progress, we
are far from being able to produce metal components in non-industrial
environments, unless it’s being done on a Tormach PCNC or similar
tool.
Tormach and similar machines for example have etched out a unique
place in the market of CNC mills, lathes, and cutting machines because
the gap between professional and consumer is being bridged. Prosumer
is the new emerging term. While this buzzword may often be a
trigger-happy description for marketers this term essential.
3D printing is certainly buzzworthy but there is still an important
gap between CNC and 3D printing. This gap shouldn’t be so much a line
in the sand, but rather, a partnership of the right tools for each
user. Both machines are capable of intruding on the other’s place in
the market, but where each thrives at affordable prices is important
to consider.
CNC mills are ideal for projects that require high-precision and
ready-to-use materials, whereas 3D printers are better for conceptual
prototypes and visual justifications. Both types of machines can be
used within these arenas, but they vary greatly in efficiency and
quality.
What the CNC versus 3D printing debate boils down to is the weighing
of capability and quality against price and efficiency – the rubber
hits the road in a debate about budget and need. With an unlimited
budget, I’d have both a million dollar stereo-lithography printer and
an industrial CNC mill with all the bells and whistles (i.e. an array
of tools, a fourth axis, etc.), but it’s an exciting time to be an
engineer right now in that I can have a PCNC 1100 and a Form 1 printer
in my garage for less than $20k and accomplish many of the same
things. CNCs and 3D printers both have their place, and as the market
continues to adapt to an ever-changing world, these machines each have
their place, side by side.”

3D Printing vs CNC by Franz Grieser
www.all3DP.com Franz Grieser is an expert in IT, printing technology,
new media and 3D printing.
First, above all else, consider the dimensions of the object you
desire to make and the material it will be made from. Then consider
machine operational methodology and capacity.
CNC milling machines take a block of solid material (e.g. aluminum or
wood) and use sharp rotating tools or cutters to remove all parts that
are not needed. So: Milling is a subtractive method – in contrast to
additive manufacturing as in 3D printing. CNC mills are
computer-controlled. The computer feeds them machine-specific code
that controls the cutting tools (just like the G-code used by 3D
printers). The models for CNC mills are created using 3D modeling
software, so-called CAM (computer-aided manufacturing) software
applications. The CNC mills funded through Kickstarter in the last
months also accept STL and OBJ files (just like 3D printers), some
come with 1-year subscriptions
3D printing: There are several types of 3D printers using different
technologies and materials. All have in common that they start from
scratch and build three-dimensional objects layer by layer (additive
manufacturing)
Choice of materials
CNC mills can work on a huge variety of materials: metal alloys (e.g.
aluminum, steel alloys, brass, copper), softwoods and hardwoods,
thermoplastics, acrylic, modeling foams, machining wax (for creating a
positive model for casting).
You can utilize a CNC mill to manufacture prototypes in the same
material that will be used for the final product .
Desktop 3D printers are usually restricted to a few materials,
typically thermoplastics (PLA, ABS, sometimes nylon) or resins.
Thermoplastics can be mixed with other materials such as ceramics,
wood, metal, but the workpieces produced on a 3D printer will not be
as robust as workpieces cut from a block of metal or wood.
As thermoplastics and resin 3D printers use completely different
methods, a resin printer cannot handle thermoplastics – and vice
versa.
Precision: CNC mills offer positioning accuracies of around 0.001 inch
(0.025 mm) and tolerances of 0.005 inch (0.0127 mm). Parts made on in
a CNC mill are much more precise.
Speed: 3D printing jobs often take hours to complete, whereas CNC
milling jobs with comparable size and complexity normally do not take
more than an hour.
Range of applications: CNC milling is the better solution when
manufacturing workpieces that need to be extremely robust and precise
and/or heat-resistant.
Cost price: You can get decent 3D printers for about $500 (e.g. the
Prusa Steel or the Kossel ), while the CNC mills featured on
Kickstarter recently start at $2,000. But neither of these will really
buy you much capacity or be able to handle material more than a few
inches square.”

WE HAVE DISCUSSED 3D PRINTING, CNC PLASMA TABLES, CNC MILLING
MACHINES, CNC LATHES, and briefly on mounting a HAND HELD ROUTER or
MIG WELDER on a CNC PLASMA TABLE, but there is one more.
THE DEDICATED CNC ROUTER TABLE
3D PRINTING, except to make small parts, is not practical at this time
for home Bat Vehicle builders, but a CNC ROUTER TABLE is. The CNC
ROUTER TABLE can do everything needed to make large 3D parts such as
those curve laden cabin roof tops, body panels, and most curvy parts.
I AM PLANNING ON USING ONE IN THE FUTURE TO CARVE OUT THE MASTERS for
the B v S DOJ Batmobile CABIN ROOF TOP, TURRET GUN ASSEMBLY, etc., and
some parts on my TUMBLER.
The auto-vehicle, boat, airplane, and thousands of other product
building industries have used computer controlled router tables for
years to make their masters; even, carving full-sized vehicle body
masters.
A CNC ROUTER TABLE is a computer-controlled cutting machine related to
the hand held router used for cutting various hard materials, such as
wood, composites, aluminum, steel, plastics, and foams. CNC stands for
computer numerical control. CNC routers can perform the tasks of many
carpentry shop machines such as the panel saw, the spindle molder, and
the boring machine.
A CNC router is very similar in concept to a CNC milling machine.
Instead of routing by hand, tool paths are controlled via computer
numerical control. The CNC router is one of many kinds of tools that
have CNC variants.
A CNC router typically produces consistent and high-quality work and
improves factory productivity. Unlike a jig router, the CNC router can
produce a one-off as effectively as repeated identical production.
Automation and precision are the key benefits of CNC ROUTER TABLES.
APPLICATIONS
A CNC router can be used in the production of many different items,
such as door carvings, interior and exterior decorations, wood panels,
sign boards, wooden frames, moldings, musical instruments, furniture,
and so on. In addition, the CNC router helps in the thermoforming of
plastics by automating the trimming process. CNC routers can help
ensure part repeatability and sufficient factory output.
QUICK OVERVIEW OF CAM (computer-aided manufacturing)
CAM software makes the CAD drawing/design into a code called g-code.
The code the CNC machine can understand. In short, CNC technology is
not very complicated. It is a tool controlled by a computer. It only
becomes more sophisticated when considering how the computer controls
the tool.
SIZES AND CONFIGURATIONS of CNC ROUTER TABLES
CNC routers come in many configurations, from small home-style D.I.Y.
"desktop" like k2 CNC, to large industrial CNC routers used in sign
shops, cabinet making, automotive, aerospace, and boat-making
facilities. Originally CNC routers added computer control to consumer
router power tools. Although there are many configurations, most CNC
routers have a few specific parts: a dedicated CNC controller, one or
more spindle motors, servo motors, Stepper Motors, servo amplifiers,
AC inverter frequency drives, linear guides, ball screws and a
workspace bed or table. In addition, CNC routers may have vacuum
pumps, with grid table tops or t slot hold down fixtures to hold the
parts in place for cutting. CNC routers are generally available in
3-axis and 5-axis CNC formats. Many manufacturers offer A and B Axis
for full 5 Axis capabilities and rotary 4th axis but you can do most
everything you would need when building with X, Y, Z axis tables.
Home hobby tables are available in 2 x 2, 2 x 4, 3 x 5, 4 x 4, 4 x 8,
and 5 x 10. A 5-6" Z axis depth is standard but 12" is often available
as an option. Prices start at 1,000.00 for small tables such as 2 x 2,
run around 6,000.oo for a 2 x 4, and 10,000.oo for a 4 x 4. There are
some on line that claim you can build your own 4 x 4 table for around
3,000.oo
CONTROLLING THE MACHINE
The CNC router is controlled by a computer. Coordinates are uploaded
into the machine controller from a separate CAD program. CNC router
owners often have two software applications—one program to make
designs (CAD) and another to translate those designs into a 'G-Code'
program of instructions for the machine (CAM). As with CNC milling
machines, CNC routers can be controlled directly by manual
programming, and CAD/CAM opens up wider possibilities for contouring,
speeding up the programming process and in some cases creating
programs whose manual programming would be, if not truly impossible,
certainly impractical.
A TYPICAL CNC WOOD ROUTER
A CNC wood router is a CNC Router tool that creates objects from wood.
CNC stands for computer numerical control. The CNC works on the
Cartesian coordinate system (X, Y, Z) for 3D motion control. Parts of
a project can be designed in the computer with a CAD/CAM program, and
then cut automatically using a router or other cutters to produce a
finished part. The CNC Router is ideal for hobbies, engineering
prototyping, product development, art, and production work. These are
found in every movie production PROP SHOP of any size and used mostly
to cut foam. They usually have several with a Z axis depth range of 12
inches. Many movie sets contain >50% foam and routed foam parts
finished in unique ways.
Note: A CNC PLASMA TABLE can be converted by adding a Z axis and a
router to do 3D cutting. This will most likely be my method to route
my Bat Vehicle parts. vertigo

Primarily interested in CNC XYZ router applicable programs today.
Looking at the feasibility of scanning in a 3D scale model body,
stepping it up to full-scale, and routing it out of foam or wood,
3/16” undersize, to allow for the thickness of steel plates. Then
conforming steel plates to dimension, attaching them to the foam or
wood, and joining them together with very short duration high heat
flash tack welds. vertigo

HOW TO BUILD PROXY TIRES; tire substitutes and why would I want to?
Think of a proxy tire/wheel as a stand in double for a real tire and wheel.
There are several benefits to using proxy tires/wheels.
You can make a cheap stand-in for the movie original tires/wheels out
of wood and mount it on your donor/build vehicle instead of buying the
real tires/wheels for thousands of dollars and then maybe finding out
they are not suitable to your build. The second benefit is that proxy
tires/wheels allow you to fit and build around them. I will be using a
set of proxy tires/wheels on my TUMBLER to set front axle lengths,
wheels/tires, and nose assembly clearances, as I will be substituting
Mickey Thompsons for the Hoosier dirt tires. I will also use Proxy
tires/wheels on my BvS DOJ Batmobile, once I have my donor Dodge Ram
1500 truck stripped down to build around. The third reason to use
proxy tires/wheels instead of the real tires/wheels when building
around the tires is to avoid accidental damage to the real tires. It
does not take much; a grinder/saw/screwdriver/punch/drill/welding
torch/hot metal slip into a tire sidewall could destroy a tire costing
hundreds of dollars. I hope to build a set of proxy tires for my
Tumbler front this weekend and will photograph the process for those
of you who don’t already know how to build proxy tires.

Cut out the wood parts for my Tumbler's front proxy tires. Measuring and cutting took about 2-1/2 hours. Expect to have 3-hours, or so in each proxy tire/wheel before I'm finished. Same process will be used for my DOJ Batmobile's tires. Will assemble them tomorrow. Once assembled I will cover the tread and inside wheel area with cardboard since they are for just for operational clearance measuring and checking. The one's I build for the DOJ will have the tread and inside wheel area covered with sheet metal roof flashing since I will be welding around them. vertigo

Assembled the proxy wheel frames. One big advantage to the proxy wheel is that you are free to experiment with wheel backsets before ordering a custom wheel/tire. You may even find the tire/wheel you were considering was totally useless. A proxy wheel costs 25-30.00 each to build. A small price to experiment with tires/wheels before buying the real tires/wheels which likely would be in the thousands.
