Replied - good question.

Randy, the Horiz. numbers are from centerline and the vert are up from the ground.

OK, so I have played a bit in wishbone, and the numbers look pretty good. I want to take a snap shot of the wishbone data and post it here, how do I do that?

Thanks,
Randy

Randy,
push the "Print Scrn" button up by the F12 key and then open up the MS paint program. Now click "Edit" and pull down to "Paste" and it should paste a screenshot. crop and resize as needed and then save it as a Jpeg file. You can then attach it to your post.

The easiest way I've found is to hit Alt-PrintScreen. That copies the currently open window to the clipboard. Then paste it into something that can save an image...Paint Shop Pro, Photo Shop, even Paint. Then save it as a .jpg or .gif, and attach that file to your post.

BTW, I AM going to follow up on this thread and post my dimensions. I have not abandoned the cause! I've got it built, except for mounting the steering rack. Commentary and pix on pages 7 an 8 of: http://locostusa.com/forums/viewtopic.php?t=2741

My current design can't get the rack in the ideal position for bump-steer. I'm leaning toward running with it and fixing it if it actually proves to be a problem (I don't think it will be), or moving the outer tie rod ends above the steering arm on the spindle. We'll see.

I'm also all constipated over the shocks. I'm about ready to chuck my pushrod ideas and just order some custom shocks mounted out where they belong. We'll see.

The biggest problem I have with bumpsteer is the fact that the Miata rack cannot be shortened enough to completely eliminate it.

OK, here's the info I have, but it is tough to read. When I resize it to mak it larger, then try to paste it to paint, it isn't there. I'm going to keep working at it.

Are the steering pick up points correct?



Thanks,
Randy

Randy,
I can't read that. For the numbers I listed in my earlier post, in 7 degrees of caster, the steering arm pivot should be located 9.1" up from the ground, 26.7" from chassis centerline, and 4.125" in front of the lower ball joint.

Hope that helps.

FYI: If you hit alt and the print screen button at the same time it should only copy the window that is the working window (blue in the title bar).

I'm using a laptop that has a Fn key to use the PrtSc function, so the alt doesn't seem to work when using the other two keys at the same time.

I may have to download wishbone to the desktop to get this stuff up on the thread...

Randy if Alt & PrtScr doesn't do the job for you, then you could try one of the tools listed here:

Bummer...

You can take the full-screen screen shot into any image editing program, and crop it down to the wishbone window. Or just post the whole desktop image in full size.

OK, I think this will work. Now I have some questions. As you can see, there is no caster. Do you set the caster by changing the X axis for the control arm mounts? Not sure how to do that. Also, the instantaneous center is way off laterally - am I reading that right? How do the steering ball joints and mounts look?

Thanks!
Randy

Thanks Randy; me too! I've cranked in more and more caster each time I drive it...I'm up to about 10 degrees. I want to keep at zero toe if I can (since high fuel economy is the goal on this 'un) but I may try a tiny bit of toe in--it's plenty quick on turn entry as is. But still I wonder what the effect of more scrub might be. I've less scrub than the donor Toyota Corrola 'cause my kingpin inclination grew when I modified the struts to take ball joints...I'm wondering if that might be my problem.
