The old watchmaker book used the technique used in diamond/precious stone
cutting - a 'stick' with hard wax - heat the wax and place object. Now an
object with a handle.
Tin is a harder 'wax' - good idea. Lead might - might be strong enough.
Ca glue is used and might work.

The old machining and watchmaking books suggest soldering thin parts to
a custom fixture. If you tin the part, wipe off the solder and clamp it
in place while heating it the error due to solder thickness should be
small and repeatable.

I cut a shallow recess in a soft collet or the top jaws of a
Microcentric chuck when I need to turn a thin washer that can't be
surface-ground. Sometimes the part also needs clamping pressure from
the tailstock

I've made an aluminum hydraulic pump rotor shim 0.008" thick by etching
a thicker machined part with drain cleaner.
