So will check in with them again in a few days.
Thanks, fo rthe help, suggestions and teachings.

MrChips,
Sounds like you found the right place, and it is for sure worth waiting a few days for the old school guy to get back. I stopped back in to my shop a couple of weeks after mine was aligned and told the guy that it is still pulling to the right enough that it's in the turn signal cancel zone on my column. He told me that he set it straight, but with the little 560's on the front it's hard to know for sure how it's going to behave and that we need to bias in a little artificial left pull by dialing in some caster bias from side to side. It's going back in tomorrow for another tweak. My point is that this guy knows alignment from a pracitcal perspective, and knows how to set things to drive right, not just to be "spec right". My only complaint is that he would have probably seen it initially if he had test driven the car after the alignment, but I think he did not want to assume it was OK with me, and I did not press him on it.

My son works at a shop but because the alignment equipment is all computerized, he can't even "Check" my street rod to see what it is at. He knows my car as good as I do but it is the equipment and not the operator sometimes that gets in the way.

Another option and one that works very well is to get an alignment gauge from Summit. I boght the SPC Performance 91000 kit. I also bought the Toe-in kit but using a tape measure actually is much easier to use. In using the alignment gauge, I wanted to see how close it was to what an alignment shop (with older equipment) would get for me and I was SPOT ON after I had mine done.

I've adjusted mine using an article in Street Rodder magazine article

http://www.streetrodderweb.com/tech/...ent/index.html

With 1/4 degree Positive caster
1 1/2 degree negative Camber
Toe in Near zero

The car drives and handles great and normal tire wear. It takes time to do it and I always recheck it after a good test drive to make sure the other factors are not throwing off the readings.
Just thought I'd share a tip.

After I wore out a couple good tires prematurely on the ‘34, I tried to get several alignment shops to “check” my street rod and none of them could get their equipment hooked up to verify my alignment settings... I decided to purchase a pair of turn plates from Harbor Freight for a $100 and an Intercomp digital caster/camber gauge for another $250 (about the cost of a couple of good tires).

I’m attaching a copy of one of the articles I used to teach myself how to do an alignment. Since I’ve gotten the equipment and figured out how to do my own alignment work, I’ve been able to barter with my street rod buds for things ranging from a couple of cold beers to borrowing tools!

Since I have done lots of chassis work and repairs over the years, I looked for and got a very good ysed Hunter alignment rack that came out of a dealership that had to do the upgrade thingy(they will only update computer specs so many years and then---you need version h as your version d is no longer supported for upgrades---

also got a older STRING version 4 wheel sensor alignment that came from a Lincoln dealer that did the strech limo cars that wouldn't fit on the normal raCKS--

everything works great, reads out what you have and not what you don't have----

you can use any specs you want and the computer has the specs up to 2002 stored in it, just the printer is an old version parallel deal with ribbon ink that you can't get stuff for and can't update op system for drivers for new ink jet stuff--

but the rack, turn tables, jacks allow me to mock up, trial fit for full travel, etc and after finish welding can do the alignment all in place


Isn't 1/4 degree of caster pretty unstable on a real road????

I think Jerome may have gotten his caster and camber reversed. I'm thinking the caster might be 1-1/2 positive and camber might be 1/4 degree negative... but I'm not speaking for Jerome.

Shoot!!! I did it again. Yes... You are right...

I always mix up Caster and Camber - Always a mental block.
1/4 negative camber
1 1/2 Positive Caster.

I was told that a pretty good start for my car was .5 camber, 3deg caster, and no more than 1/16th toe in. I will see what the guy says in a few days.

as for my own equipment, that would be cool. But I have to stay pretty small in equipment storage. I am active military and have to move alot. Until I decide enough is enough anyway.

That's great you found someone to take care of the alignment for you..

BUT for anyone else wanting an alignment........
Regarding the newer alignment machines, it in my understanding that since they are computerized most should be able to a 2 wheel alignment & won't need to put any equipment on the rear tires for any of the alignment.
I would ask that question at the alignment shop just to be sure if they say NOPE can't do it....joe

I think your specs are pretty good for a starting point, and thank you for your service, by the way. Your MrChips handle takes a new slant!!

"Your MrChips handle takes a new slant!!"

How's that? LOL Actually it comes from my rating. I am a Damage Controman in the Coast Guard. We started out as Carpenters Mates and their nickname was Chips (for woodchips) The Mr is a respect to my grandfather who was a carpenter.
And no need to thank me, I consider it an honor and have considered it an honor for 21+ years now.

LOL more - sorry, my old addled brain confused two old movies, Goodbye Mr Chips and Mr Roberts, and I had Mr Chips being a military officer. Regardless, thanks for your 21+ years!!
