Relevant Tire Observations:
Tire construction, diameter, width, inflation pressure, temperature
(heated SAM-43 Super Swamper tire to 100-degrees with an electric
heater), and loading are all inter-related to the final tire
measurements.
The bigger the tire the more the measurement error differences between
the cold non-mounted and wheel mounted heated and inflated tire.
Note: Once tires begin to roll the friction between the road and
flexing of the tire begin to generate heat above the environmental
heat.
Not much of a problem with Bat Vehicles that use a fairly conventional
tire but a major relevant source of error measurement for the dually
spacing of the Tumbler’s rear tires and even more so for the Batman V
Superman DOJ/Justice League Batmobile fender well/assembly clearances.

“One very important thing I learned when working out the rear dually
wheel setup on my Tumbler is just how important it really is to mount
one of the rear SAM-43 Super Swamper tires on a 16.5 x 12 inch rim and
weight loading the setup with 1500 lbs of weight before taking
relevant measurements. My rear dually setup plan is to have 2-2.5
inches between the dually mounted tires. Had I not taken the time to
do this set up testing prior to planning my rear dually setup I would
have made some major measurement errors as the attached photo-images
illustrate.”

Good work Vertigo. Great to see how good it looks with the wheels on and set up. Really helps to give you a true idea of the size of the vehicle your building. Its funny when your building a tumbler at the start everything tyres body seems massive but over time it just becomes normal or even fools your eyes into thinking its to small lol. Glad to see the progress Vertigo well done.

Thanks for the kind words.
I have experienced the habituation effects you described with my Tumbler.
With the rear dually wheels installed I too am re-awed by the size and mass of this beast. vertigo

Mounted my two outer rear dually tires on my Tumbler today.
Took some measurements from the total rear end setup.
Quite impressed with myself.
I was looking for 2 to 2-1/2 inches of spacing between the rear dually tires.
Measurements of the spacing today revealed my actual spacing to be 1-3/4 inches.
Very tolerable and should work just fine. vertigo

Using welding rods/electrodes that have absorbed too much moisture is the number one cause of bad welds for the non-professional and home welder.
How to Prevent Hydrogen induced Weld Cracking and Porosity Problems. Part One
Lincoln Welding Corporation
“Electrodes for Shielded Metal Arc Welding (SMAW) or stick electrodes
must be properly stored in order to deposit quality welds. When stick
electrodes absorb moisture from the atmosphere, they must be dried in
order to restore their ability to deposit quality welds. Electrodes
with too much moisture may lead to cracking or porosity. Operational
characteristics may be affected as well. If you've experienced
unexplained weld cracking problems, or if the stick electrode arc
performance has deteriorated, it may be due to your storage methods or
re-drying procedures.
Follow these simple storage, exposure and re-drying techniques to
ensure the highest quality welds, as well as the best operational
characteristics from your stick electrodes.
Storing Low Hydrogen Stick Electrodes
Low hydrogen stick electrodes must be dry to perform properly.
Unopened Lincoln hermetically sealed containers provide excellent
protection in good storage conditions. Opened cans should be stored in
a cabinet at 250 to 300°F (120 to 150°C)
Low hydrogen stick electrode coatings that have picked up moisture may
result in hydrogen induced cracking, particularly in steels with a
yield strength of 80,000 psi (550 MPa) and higher.
Moisture resistant electrodes with an "R" suffix in their AWS
classification have a high resistance to moisture pickup coating and,
if properly stored, will be less susceptible to this problem,
regardless of the yield strength of the steel being welded. Specific
code requirements may indicate exposure limits different from these
guidelines.
All low hydrogen stick electrodes should be stored properly, even
those with an "R" suffix. Standard EXX18 electrodes should be supplied
to welders twice per shift. Moisture resistant types may be exposed
for up to 9 hours.
When containers are punctured or opened, low hydrogen electrodes may
pick up moisture. Depending upon the amount of moisture, it will
damage weld quality in the following ways:
1. A greater amount of moisture in low hydrogen electrodes may cause
porosity. Detection of this condition requires x-ray inspection or
destructive testing. If the base metal or weld metal exceeds 80,000
psi (550 MPa) yield strength, this moisture may contribute to
under-bead or weld cracking.
2. A relatively high amount of moisture in low hydrogen electrodes
causes visible external porosity in addition to internal porosity. It
also may cause excessive slag fluidity, a rough weld surface,
difficult slag removal, and cracking.
3. Severe moisture pickup can cause weld cracks in addition to
under-bead cracking, severe porosity, poor appearance and slag
problems.
Re-drying, when done correctly, restores the electrodes' ability to
deposit quality welds. Proper re-drying temperature depends upon the
electrode type and its condition.
One hour at the listed final temperature is satisfactory. DO NOT dry
electrodes at higher temperatures. Several hours at lower temperatures
is not equivalent to using the specified requirements.
Electrodes of the E8018 and higher strength classifications should be
given no more than three one-hour re-dries in the 700 to 800°F (370 to
430°C) range. This minimizes the possibility of oxidation of alloys in
the coating resulting in lower than normal tensile or impact
properties.
Any low hydrogen electrode should be discarded if excessive re-drying
causes the coating to become fragile and flake or break off while
welding, or if there is a noticeable difference in handling or arc
characteristics, such as insufficient arc force.
Electrodes to be re-dried should be removed from the can and spread
out in the oven because each electrode must reach the drying
temperature.
(1) Pre-dry for 1 to 2 hours. This will minimize the tendency for
coating cracks or oxidation of the alloys in the coating.
Storing and Re-drying Non-Low Hydrogen Electrodes
Electrodes in unopened Lincoln cans or cartons retain the proper
moisture content indefinitely when stored in good condition.
If exposed to humid air for long periods of time, stick electrodes
from opened containers may pick up enough moisture to affect operating
characteristics or weld quality. If moisture appears to be a problem,
store electrodes from the opened containers in heated cabinets at 100
to 120°F (40 to 50°C). DO NOT use higher temperatures, particularly
for electrodes from the "Fast Freeze" group.
Some electrodes from wet containers or long exposure to high humidity
can be re-dried."

How to Prevent Hydrogen induced Weld Cracking and Porosity Problems. Part Two
Welding Rod/Electrode storage issues.
In a low humidity 70-degree environment most welding rods have an
eight hour exposure time after the package is opened before moisture
begins to have some intruding effect on the rods.
High humidity will drop that to 4-hours.
Many structural welders don't use rods after 4-hours of air exposure.
If moisture appears to be a problem, you can store the remaining
electrodes from the opened containers in a heated cabinet at 100 to
120°F (40 to 50°C).
Welding rods/electrodes come in 5LB, 10LB, and 50LB containers.
Per pound rods sold in 50LB containers cost the least but require a
heated box to protect them from moisture.
I solve my moisture exposure risk by buying my welding rods/electrodes
in 5-LB sealed packages.
18-rod per pound X 5 = 90 rods
I usually weld at a stick use rate of 12-18 rods per hour depending on
the welding complexity of the project.
6011 rods cost me around 3.60 per pound (18.00 for 5 LBS)
I usually use most of a 5 LB package in 8-hours.
If any remain I seal them in a plastic tube bag with a vacuum food
sealer and write the time exposed to the air since opening the
original package. I also break down a 5-LB package, and immediately
seal them in plastic tube bags with a vacuum food sealer, 18-rods in 4
bags, 9 in 1 bag, and 3 in 3 bags. These I use for small welding
tasks. The stray rods with moisture laden flux coatings I hit against
my steel welding bench to knock the flux off, put them in a plastic
storage tube, and use them as weld filler material.
NOTE: I don’t use welding rods on my Tumbler with more than 8-hours of
total air exposure time since opening. I use the rods with more than
8-hours exposure for other general purpose welding tasks.

How I Prevent Bites from Spiders Hiding Inside Welding Gloves and Jackets.
Ever worry about finding a black widow or brown recluse spider inside
your welding gloves or jacket?
Here is how I protect against this.
After I finish a session of welding I hang my welding jacket and
gloves up and use an electric fan to dry them sufficiently. Once dry
I put them into a plastic truck with a few dozen moth balls in the
bottom. I learned this trick from a professional welder.
Never found a spider after using this method but I guess one could
still get bit if a spider wandered into their gloves or welding jacket
a few moments before they put them on. vertigo

Ever found yourself welding in a low light situation?
Like inside a Bat Vehicle?
I modified a welding helmet by mounting a miner’s light on the top
with small bolts.
Often thought about the need for a helmet light whenever I found
myself welding in a low light situation, but forgot about the need
after the situation was over.
See photo-image if you have a similar need. vertigo
