Well I'm back from my adventure down under... we self isolated on the Great Ocean Road... wow what a great way to spend a couple of weeks when you can't race.
So version 5, 6, or 7 of the chain/belt tensioner have come and gone... but I think I have one started that might work.... it is tacked in place and I will see if it is going to stay.
To take my mind off of that, I have been aligning the axles and think I finally have that. I fought repeatability for a couple of days till this morning, then I figured out my issue, the Laser was not sitting flat every time..... so I switched lasers.
So I am taking comments on my procedure... First I measured to get everything to what I thought was close to in line. I use a C channel to average the sides of the car... and shoot the laser from the axle, perpendicular down the side of the car. Then make it the same on both sides and the rear axle should be straight. Of course this required me to first make a .030 shim, and then remake it to a .020 shim. The thread on the adjusters was to course to get it measuring closer than an 1/8. Then I remeasured the front to rear, it was within a line width on the tape. Used that info to be sure the front axle was then centered in the car. Moved the laser to the front and shot back to the rear. The left was outside, right was 5/8 inside... making them the same was about a flat n a half shortening the 2 left 4 bar links. Yep I remeasured the lengths between the axles... still looked the same.
