Those are degree marks for either two and a half degrees or one and a half degrees. That you want to try to bend the axles. I generally find that a lower bend.
The one and a half is more than enough to get my wheels to ride on the outside of my my axles like i want so the way this. Works im setting it on the 15. Side.
And i want to make sure that my head of my nail is completely clear this. If you put the head all the way up when we set it theres a good chance that well break the heads off of the nails and ive done that a couple times. So i set that right where i where i want it ive got the nail seated in the groove.
Then that whole assembly. Im going to take back down to my floor. And this really doesnt take a lot of force i tend to go with smaller lighter hits and do more of them until and youll be able to feel it because its its not a lot.

But youll be able to feel that die kinda drop down and seat and when thats done we now have a bent axle. Now before i take it out of the jig. The last thing that i want to do and its very important is i want to mark.
Where up is on that head of that nail now thats going to help me orient. It when i go to put it into the car that i know which direction up is in my bend. I have a little pair of axle pliers that allow me to twist or turn that if you dont have a set of those its a very very good investment to have ill show you what those look like in a later video.
So thats it now youll notice just barely that you can see a bit of a bend in that axle. So what that allows us to do when it goes in our car is our car our wheels instead of being straight up and down. Theyre actually gonna cant out a little bit and that means as the as the car runs.
The tires. Actually going to be sucked to the top of the axle. Which means our friction is going to be right here around our polished axle head and the polished inside hub of our wheels.

Rather than having the wheel rub against the inside of the car. So this is just a stock wheel. Theres no lubrication.
Theres no axles. Theres no nothing in this yet. And we should be able to get at least about a 10 second run out of that without any lubrication.
I think thats looking pretty good now when we finish up ill go ahead and ill pack these axle hubs full of graphite well go ahead and well polish the inside of the plastic wheels with graphite ill cover how to do that in a later video. And we should be able to spin that and get about a 20 second count by the time. Were done thats thats what i shoot for if we can hit 20 seconds.
On a free spin. You know weve got very very little friction in not have a subway. .
