Degree bend on DFW

[davet]

I'm new to this so I'm trying to understand. I read a post a while back by Kinser about the steep bend so that's what we did this year and were successful. While adjusting it I often didn't even know if I had twisted the axle at all and it would change steer by 1 1/2". I don't know what it was exactly but it was deep.
I don't understand the "smaller footprint" idea though. The wheels are hard plastic running on an aluminum track. Once the bend is far enough to overcome the bore to axle slop the wheel is now running canted and no longer flat on the track. I don't understand how more of an angle decreases the footprint. I'm wondering if just enough bend to overcome the axle/wheelbore slop isn't the best way to go. Easy adjustments and less body friction.

More of an angle decreases the footprint on the rail and track. Picture it this way. If you had no degree cant and ran that wheel against the rail, you'd be touching 1/4" of that wheel surface (height wise, plus the width of that wheel) all the way down the track. (center rail is 1/4" tall). Now you add some bend to the axle and now 1/4" of that wheel is no longer touching, we'll say 1/8" of the wheel. The more cant the less it touches. On the opposite side of the wheel you're also moving that to more of a pointed surface rather than flat, meaning the surface of the tire you now run on is the edge of the outside of the wheel. Less surface touching both the track and the center rail the more cant you go. Less footprint as Kinser says.

This has been a great topic and I'm looking forward to seeing what the new testing shows. Really appreciate the help, I've learned so much in the last 2 months.

Hey 561,

If you are new here let me give you some advice.

DO listen to Kinser if you want to get faster.

DO NOT listen to ObsessedDerbyDad.

Did you notice that he just quoted Kinser for saying something that GX said near the beginning of this thread?

nuff said.

I think that BR was the first one that brought the question/ answer to my attention in the post entitled "Can't do that".

I think I got the answers I been looking for, did lots of reading inspired by this thread. Let's see if it translates to the speed I need to gain

I've got several things to back me up. Look down v /images/boards/smilies/biggrin.gif

Pshh. The guy gets lucky a couple times... /images/boards/smilies/wink.gif

I was referring more to the idea of the canted drill job, angled axles, etc. all adding up to a really steep angle on the wheel. There is a point somewhere where the angle will cause a slow-down. (I expect it's > 10*; but I'm not going to expend the effort to find it. There are plenty other things I know I'm not doing really well that need to be sorted first)

I've never tried the double angle and I don't think I could make it work. I think 5kids does something like that but His set up is more elaborate than my simple mind could handle. lol

Sounds kinky!

It is only recently that I have decoded the genius behind the 5K set up.

It only took me about 6 months after building a car with his approach.

This guy is way ahead of the curve.

get it?

Kinky?
