Recommendation? Metal shims

[annr]

Can anyone recommend some metal shims in 0.01 mm increments that would be approximately 90 mm x 7 mm.

I'd like to raise the height of a parallel bar by approx 0.03-0.06 mm and would like to test the adjustment before I move any parts.
I found some 0.03 mm paper that worked-- but my work piece is wet so paper is not ideal and I'd like to test a each 0.01 mm increment because this will also affect an eccentric bearing and some other specs on the machine that I would rather not have to adjust thanks..

The easiest thing would be to slice up aluminum beverage cans, but I think they are a bit less than 0.010".

What about finding some older feeler gauges that no one wants, you could just take them apart and take out the shims needed?

Plan A) got to a machine shop and have them made.
Plan B) haywire some random chunks of metal from around the house for this.

Aluminum foil might work. Get a roll of budget stuff and a roll of heavy and you should be able to combine them to get the thickness you want.
You could buy shim stock from an outfit like Grainger or McMaster-Carr, but that would be pricey.

Aluminium foil - Wikipedia

en.wikipedia.org

Aluminium foil (or aluminum foil in North American English; often informally called tin foil) is aluminium prepared in thin metal leaves with a thickness less than 0.2 mm (7.9 mils); thinner gauges down to 6 micrometres (0.24 mils) are also commonly used.[1] Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy duty household foil is typically 0.024 mm (0.94 mils). The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful.

That's a great idea, and foil seems like it would be easy to cut to size, layer, and not expensive to re-do. I might even be able to wrap it around the parallel bar well enough to temporarily secure it to the machine. Hmm...much better than moving a bunch of screws and regretting it.

Thanks, another good idea. Looks like the thinnest Mitutoyo is 0.05 mm, and if that's the magic number...

thanks. I need something dead flat, but worth considering.
