do the wheels need to be pointed dead straight when checking camber?
How improtant is it that the gauge is on the spindle centerline, can it be a little off center?

I have thier directions, but a step by step of the process would be great, if anyone is a pro with this guage...

thanks,

I have this tool. Place the tool as centered as possible on the hub. IIRC, you've got to remove the dust cap to place it on the hub and the magnet is of sufficient strength to pinch your skin good. be careful.

Wheels straight ahead and of most importance is the floow being level from side to side. If not, shim low side with masonite or something like that.

Caster is a little more challenging but I believe my problems have been due to my floor not being level enough.

Drop me a pm if you have more questions...
 
I use it as the directions are written. For me, it's worked great. I've changed my settings a handful of times, trying diff setups and it's that complicated. Can I get it as exact as a pro with pro equipment and a perfectly level working surface...no. I can get it close enough that I've not experienced any bad side effects or abnormal tire wear.

The trick is to take your time, have a setup in place that allows easy rotation of the front tires ie: 2 pcs of 1/8" MDF with a small amout of graphite between (or wax paper) or a ball bearing rotating assembly.
 
Another trick is to use plastic trash bags under the tires.

You'll be amazed just how simple it is to measure alignment. Changing the alignment to meet a certain spec may take some trial and error, though. It's not rocket science.
 
When I did Shag with one, each time I changed the camber it affected the caster, so back and forth I went until suddenly it all fell together. Very nice device to use. Afterwards I took the car to a local alignment shop and they were surprised how dialed in I had the car.
 
An alignment guy taught me to do it in this order: camber, caster, toe. I've had good results with my HOWE gauge but how it figures the caster is a mystery to me. . .
