Default Powdered Graphite?

I was helping my son build his Pinewood Derby car this past weekend and wondered about using powdered graphite on our cars. Powdered graphite is all that is allowed on the Pinewood Derby cars and it sure does smooth out the axle/wheel action.

There are all kinds of areas on these cars.... hinge pins, pivot balls, axles, etc, that could benefit.

Anyone ever tried it?

hi cdelong!

Powdered graphite has been being used to lube the dogbones since ages in RC. Also Mo2S based spray lubes (loctite, CRC).Quite expensive and difficult to find here in Europe, at least un my country.

They are called dry lubes, a kind of lube film very adhesive that doesnt atract dust and avoid wear in metal-metal contact.

Best Regards

I know a lot of people could careless about the toxicity of our hobby, but I thought I would post this link anyway.

If we would follow all the chemical instructions from the multiple products we use in RC racing (beging with the nitro from the fuel, with a lot of possibilities to develop a cancer)

, we of course would be all playing golf.

Yeah, I know.

When I was younger, my family was big into hot rods. Back in the day, we were all a lot less educated about what we were exposing ourselves to - dry sanding without a respirator, using a grinder without hearing protection, getting all kinds of chemicals absorbed through the skin. All not good.

I'm the only guy that wears hearing protection at my track. Because our pits are right next to the track, about the only time I'm not wearing it, is when I'm tuning my own car and when I'm racing. I try to wash my hands if I expose them to any chemicals and I carry those baby wipes if it's just not convenient to make my way to running water. One thing I can't avoid, are the exhaust fumes. I try to limit my exposure, but like you said - I like this much better than I like golfing.

Cheers

I find a great substitute is the dark grey grease that comes with the dremels. Its easier to get in Europe than most other usable products. I even use it on the thrust bearing on the clutch. Sticks there great and keeps the dirt out all day. Only needs replacing when you strip the car to clean it.

I use bicycle products with dry lube on my buggies and off road vehicles.
Finishline has some great products.

Thats all well and good. I'm concerned about safety as well, but take it FWIW. I don't see many people fueling their cars with methanol resistant gloves and thats probably the worst stuff we see at the track. It's EASILY absorbed through the skin.... causes formic acid in the bloodstream..... and rocks up in your kidneys. Heard of dialysis??

I'm just a dumb chemist by trade
