So, I wanted to convey that, because it will be hard for people to help you, in answering this question. As so many packs due not allow this. So less people have done it or tested with it, ect.
The best shot of giving you a reply, that may help you. Is as follows.
Some of the reason people use the teflon bushing, is they are also running needle axles or a smaller diameter axle and the teflon bushing or used as the axle head, Is smaller and easier to work with, then trying to polish and get accurate a more typical axle head.
But you are also outside of my realm of beung able to truly give you a strait forward and good reply to you're question.
All I can say, is sometimes it works and sometimes it does not. In part there are different kinds of teflon out there, Some who sell it for this application. I asume they have build many cars and track tested it and confirmed it is faster and a better way to go when allowed.
Back when I tried them. It was a pain for me to cut them and get them flush and true or for that matter. I was turning down teflon rod to get the size i wanted or was atempting to do and use.
out of 60 I made. i was able to get 8 to 12 I liked and used. But mine where for needle axles that had no head. for bearing cars.
I never got it right or did well with it. I recommend asking and contacting others at another forum who have more expierence with this.
Thanks again for clarifying. I understand.
I am trying to make a car with fenders that cover the outside (hub area) of the wheel.
Would it be necessary to cut the side of the fender to allow for calipers to measure before a race?
Or could I drill a hole in the top of the fender to allow for a micrometer?
Sorry for all of the questions.
Could I make a tool that will fit into the fender area, like a thin piece of plastic that has a half circle (7.5mm dia.) cut from the edge?
