I'd be shocked if there were even 10 folks on the board that could actually measure the flatness of a shim.

Good lord Mr I. . .

Note that I mentioned I use a set of mics to check flatness. . .

I just measure around the perimeter in 4 or 5 spots and note the largest and smallest reading in .0001"ths

When I was done the opener was .002" thinner and the variance between my low and high measurement was *less* than it was when I started.

Hence it was flatter than came from the factory.

How is this hard?

We're not on the same page-are you measuring a new shim or the one you took out?
If the state had not cut funding for the mental institutions, this project could never have happened.

The one I took out of the bike.

Why would you buy a new shim and sand to size when you can do that to the factory one for free?

I've only done a couple valve adjustments. . .

am I missing something?

I would just like to point out that .0001" can change based on the 'feel' of the guy using the mic.

or if your eyesight is bad and can't read the vernier  :D

True, that's why you have the same guy check before and after ;)

I was on one.

Now I'm waiting to see if they'll let me on the next one ;D
