Got the new bracket made as well as the diagonal measurements for a cross check. That came out within 1/16". The straight line front to back came out within 3/32". Mounted the spindles and the overall track is too wide. 1-1/2" overall. Damn it!!!. Where, how, I don't know. I'll fix it next week.

I just figured out the picture thing. The size of the older posts were too big. I made the last one smaller and it orientated it perfect. So I have to mail them to me smaller size and then save it then post. :BH:

I had the day off today and mocked up the upper control arms. worked out pretty well. I do have to shorten an arm to get the camber, siting at 6 degrees of caster and 0 camber. task is to shorten the small tube and weld it out and make it look more appealing with the sanding disc. I love those things!

I never have a problem with orientation. It still appears that you are not holding the phone in the standard way. When you take a landscape picture the big button at the bottom of the iPhone should be on the right side, not the left side.

Hey Steve,

What I see looks good. I'm thinking you will wind up with what you want as far as geometry goes.

Me being a lousy photographer is the main reason I didn't do a build log. Even though I did use a real camera, not a phone. My cousin has an Iphone and his photos are pretty good. He doesn't try to post them here however.

Cheers

Hi carguy, yes home button on bottom. I also looked for rotate on preview screen and couldn't find one. I did this post on my iMac, now when I look at this post on my phone their all perfect.

I knew I was in for it when I decided to use the round tube, in that the brackets where going to be a challenge. I can't lie. It absolutely is a challenge. I am also seeing that the ackerman angles may not be all that steep. I honestly don't know what I need at this point for good angles. Doing some looking at it last night and looks like about 15-20 degrees from spindle to inner tie rod end. the steering rack will not sit behind the axle center at all, may be even , but not behind. Hopefully next week end I'll have the other side done.

Those rear suspension links need to be in double shear and of significant strength to hang the car (x2 or more) by them.

Tundra,

Staniforth suggests that the included angle between the steering arm and the track-rod end be 75 degrees for 100 percent Ackermann on a front steer car. The angle between the rack axis and the track rod end is immaterial.

I think you're going to have issues with those upper front arms. Since the two inner bolts aren't on the same axis, you're asking for a lot of deflection from the bushing. You can get away with that orientation with rod-ends since they have three degrees of freedom but bushings really only give you one degree (rotation about the bolt's axis).

So free movement doesn't account for anything? Just asking. I follow I don't see the deflection.

I was just looking at that too. As I followed down the page, I saw your comment. I agree 100%.

As far as not "seeing" it, you don't really have to put your head around it in theory right now. Simply tighten up the outer clevis and disconnect the control arm ball joint from the upright. Then "feel" the interference as you move the control arm up and down. You will rapidly understand.
