That was the long way to say I dont know. This is a refreshingly good new question that needs to be answered with the floss.

I hesitate to articulate for the fear of deviating from the true course of rectitude.

Might the floss or wax paper shim affect the original camber, though, if located at a single tangent?

If you can't start over you have two choices. One, if you first drilled for a .089 axle then step up to the 91-92 axles and see if that works. Two, if you must shim, then take a 6 inch aircraft drill bit (the same size as your original drill bit) and shim it. Then use a good quality 6 inch square and check the toe. If the toe is perfectly zero, then you can go with that. The cant might still be off some. It's tougher to check you the canted hole. It's possible with trig calculations, but I'd start over.

I liked the way the "floss fix" made the axle tight, but still easy to break loose to remove and re-prep, and so I went to a bit of an extreme that probably costs some speed, but allows a Cub to mess with the wheels much easier. I drill a slightly larger hole to begin with [ 2.30 mm metric]. I drill it ( or the Cub drills it) way past what is needed so that the axle holes meet up and you can see through the car. This is done with the block, both canted and straight.If one wheel is raised, add a plain vanilla hole to that side above where using floss.
I then thread a few loops of Teflon coated floss all the way through and tie tight across the bottom of the car. Now you have a nice snug fit that is tight enough to take jumping off the track without the tuned axle getting moved, but easy to remove the axle later. It also puts a nice smooth Teflon spot for the DFW to ride on right under the axle hole. Buy threading through and pulling, it is nice and straight and So now it is NOT at a single tangent point, but is the ultimate magic parallel line touching the length of the axle and pushing uniformly against the side. Cars made this way can have the wheels swapped out with all kinds of experiments quick and easy for the Cubs to see on the same car what a "process" change can do.

+1 on the floss I used this fix last week it worked great.
