Why Tungsten and Moly are NOT good Additives for PWD Dry Lube

Graphite is the key to a winning dry lube.  Plain and simple.  Important things to know about graphite is Particle Size (mesh–large flake to super fine)
Hardness (does it easily smear, or is there a gritty feeling left), and Purity (if its not 100%, what is the filler).

Anything else added to graphite, makes it slower.  Period. Tungsten is harden than graphite, so addition of tungsten to a graphite blend only adds an abrasive (tungsten is harder than your steel axle.  Think about it).  The addition of Moly makes any dry lube compound a single layer lube as you can not stack multiple layers of moly.  Why would you want a single layer lube to begin with?  Both these additives only become a key part of lubrication under HIGH HEAT or HIGH PRESSURE.  If these elements are not present, moly and tungsten become an abrasive.  Both carry a higher a higher rockwell hardness scale rating than pure graphite.  So why do we want them in our lube?

Answer is we don’t want them in our lube since there is literally no stress in a 5oz gravity fed rolling application.  Plain and simple.  Look at the science, do the math.   Pure graphite is the key to a winning lube.  Stacking layers of lube during a proper break in process that can shed away with friction with each race.  How many times will your scout’s car race during a single event.  If you want the fastest first race car, then you know what lube to use.  To learn more about graphite dry lube, visit this link.

There are a problem with the BSA Wheels. I have very limited amount of sets left that are machinable that do not wobble.
Matched inner bore will not be available. #15 molds are no longer premium wheels. Please watch this video: https://youtu.be/OGlZlB_h7a4

Just to be clear, I do not sell wheels that wobble. I will not sell junk wheels. I rather have no sales, than have my name associated with junk wheels.
The wheels that you see in the video are thrown away. They are not used.

BSA is aware of the problems, I am the second person to file formal complaint. Just remember I buy from same place you do.
I have been instructed by national scoutshop not to place another order for wheels. So at some point I will run out. I have no special inside line for a better product.
