| Your build is looking great can't wait to get mine started. If possible I would love to ask you a few questions about your build. If you would message me that would be awesome. Thanks

I will be using elements of this technique to build other parts for my Tumbler
The basic steps to fabricating compound, intersecting, and curving
multi-directional shapes in metal.
Study the part or collective assembly to determine the lines of forces
travel (tensile-compression-elasticity) and mark these on a drawing or
photo-image.
Make a list of those that you can separate by single directional lines of forces.
Flats and plates
Curve and radius
Methods of integrating single direction lines of forces.
Intersecting the flat directional lines of forces for two or more
pieces and welding their contact edges together.
Bending flats around a curve and welding their contact edges together.
Make a list of those that cannot be separate by single directional
lines of forces.
Spherical and semi-spherical
Compound curves and radius
Methods of integrating and shaping multi-directional curving lines of forces.
Metal stretching
Heating the metal and hammering to selectively vary thicknesses
Geometric translation into curves.
Intersecting the flat directional lines of forces for three or more
pieces and welding their contact edges together. Then blending into
multi-directional curves by adding or subtracting metal.
You can also blend the multi-directional curves by using resin, epoxy, Bondo, etc. to smooth out the welded geometric intersection. Many materials can be used to achieve tis result. Large and small parts of varying complexity can be made using this technique.

hey sly,
Used my oxygen/acetylene torch to cut the radius flats from 3/8 inch plate steel.
It was handy and still quite effective though the cuts are not as clean as those done with a plasma torch.

hey paulwayne,
Thanks for the kind words.
Your Tumbler is looking outstanding as always. Together with your Batsuit I imagine every kid and most adults stand in awe of the two.
On weight, my limit is 4-1/2 to 5 tons. vertigo

| Hey Vertigo glad you like it still i look at bits as to how i could improve or better it but everyone seems to really enjoy the spectacle of it. The Batman in the picture is my friend Neil from the superheros belfast company . He has ordered a new movie correct suit so it all goes together well. What is your plans for transport Vertigo i know that its a bit away but it all takes planning and building/ preparing. I love the detail and effort you go to with pictures and the explanation and encouragement to others to start a build. I have to say nothing can prepare you for opening the garage door and having a tumbler sitting there to do whatever you want with.

| Not wishing to hijack your thread but i meant to say the second picture of my car is at the famous dark hedges that are featured in the game of thrones series for anyone that is a fan i believe it is called the kings road.

“Hey Vertigo glad you like it still. I look at bits as to how I could

How about adding an afterburner cold flame special effect?
Part One
Close to an audience, you might use a cold flame special effect with
just CO2 and a red, orange, or yellow filtered high intensity flood
light inside the afterburner. (Like the hand held search lights with
1,000,000 + candlepower.) The rushing exhaust of cold liquid CO2 as it
changes to a gas and "snow or white translucent and semi-reflective
dry ice solid particles" diffuses the light into a swirling jet of
motion. Deflection tabs can a mounted inside the exhaust nozzle to
refine the shape of the exhaust gas pattern. Coupled with a recorded
jet exhaust sound effect and it appears very believable.
Best things about the cold flame special effects are no heat or burn
risk to audience, no fire hazard, and no residues left behind like
those from glitter and colored powder injectors.
Note: Touching a cold afterburner nozzle that may be below zero can
cause freeze burns.
Yes, I know you can get glitter and colored powder in bio-degradable
formulations but they can take quite a while to degrade.

I placed a copy of this post here for the benefit anyone that might be
able to use this information in planning and/or building a Bat
Vehicle.
How about adding an afterburner cold flame special effect?
Part Two
Why CO2 is the go to gas/solid/liquid for cold flame special effects.
CO2 is normally a gas at room temperature and pressure. It has to be
stored under high pressure to make it a liquid. When you release the
pressure, the gas expands enormously and cools to make a huge white
jet that allows the carbon dioxide gas to expand, cool, and turn into
a mixture of frozen "snow or white translucent and semi-reflective dry
ice particles" and gas.
Basic Science Characteristics of Carbon Dioxide as a Liquid, Gas, or Solid.
Liquid CO2 is produced by compressing and cooling CO2 gas. This liquid
is a clear transparent fluid. Liquid CO2 cannot exist as a liquid at
atmospheric pressure. It must be pressurized above 60.4 psi to remain
as a liquid. At this pressure, Triple Point, CO2 can exist as liquid,
gas and solid. Below this pressure it will flash to a gas and solid.
More specifically, it behaves as a supercritical fluid above its
critical temperature (304.25 K, 31.10 °C, 87.98 °F) and critical
pressure (72.9 atm, 7.39 MPa, 1,071 psi), expanding to fill its
container like a gas but with a density like that of a liquid.

How about adding an afterburner cold flame special effect?
Part Three: Exhaust Nozzle Basics
I received at email asking for information on nozzle designs and how
to prevent freeze up.
The two major problems he referred to are related to allowing the CO2
to exit at high speed, so any snow that forms doesn't block it up and
how to best produce turbulence in the exhaust gas/snow mix.
For many years these were problems with the CO2 fire extinguishers
until they were finally resolved in 1975 by the Brooks Equipment
Company.
Given that their CO2 exhaust nozzle design has not been improved on,
this would appear to be the best place to start when designing a Bat
Vehicle afterburner exhaust cold flame special effect.
If I were building this effect I would start with an intact CO2 fire
extinguisher horn and surround it with three-six small high intensity
lights with a mix of orange, yellow, and red filters.
The mix of colored filters and gas turbulence would give the effect a
pulsing flicker flame effect. One could even set up a pulse flicker
control on the lights themselves. The sophistication and effectiveness
of the afterburner cold flame special effect is only limited by the
user’s imagination.
Carbon dioxide fire extinguishers
Artwork: A typical carbon dioxide fire extinguisher. From US Patent
3,901,322: Fire Extinguisher Discharge Horn by Jack Winston, Brooks
Equipment Co., Inc., August 26, 1975, courtesy of US Patent and
Trademark Office. Photo-image attached.
The CO2 fire extinguisher horn is designed very carefully to stop two
major potential problems: It allows the CO2 to exit at high speed, so
any snow that forms doesn't block it up, and creates uniform gas/snow
turbulence. This typical design from a patent by Brooks Equipment in
the 1970s solves both problems.
