Adding alcohol to graphite

Post by Speedster » Sat May 12, 2018 3:54 am

I read in a set of Girl Scout rules that adding alcohol to graphite makes it a "Liquid lubricant" and therefore illegal. I've never heard of doing that before, don't know how I would do it, and don't know any advantage in doing it. Does anyone know why a reason like that would be in scout rules?

Well Speedster,
Some believe that it makes a paste to coat the axles and that it’s sticks to the axle when dry.

Or that the wet mixture packs into the wheel bores better.
And when drys forms a small graphite bushing.
Hope that helps.

That's very educational. Thank You. I had never heard of that before. It makes me wonder how a local Girl Scout troop learned of it.

Hard to say for sure Speedster!

It could all stem from this lecture
http://www.pinewoodderbyphysics.com/pdf ... e%2016.pdf
Car Lecture under lecture 16
Or some different web sites .

There are some good write ups about it as well.

Adding alcohol to graphite doesn't seem like a worthy road to pursue. That said, there may be some potential for using an alcohol/tungsten-disulphide (WS2) mixture for coating the bores and hub surfaces prior to a graphite lube.

The key would be applying the paste to a rotating wheel until you get a silvery sheen left behind.

I believe Bracketracer has used WS2 as an underlayer for graphite lubes in the past.
