Feeler strips
MCTID:
I used to use feeler 'strips' to measure the clearances around Turbo Compressor Impellers. The strips came on a coil and I cut off about a metre at a time to feed around the Impeller/ Casing to check what the clearances were.
Another 'unusual' technique I remember at the time was micro peening areas of a shaft journal to bring up the outside diameter so that the sensors read zero run out when turned by hand. If the sensors detected excessive run out as the Gas Generator (Rolls Royce Avon Jet Engine) got up to speed, the whole Turbo Compressor shut down and it took ages to set it all up again, often needing to replace the main journal bearings.
We also had to allow for the Turbine Shaft to lift as it expanded so that it came into line with the Gas Generator Shaft and ran perfectly true within milliseconds.
You can't beat 'kidology'.

I got a set my self.
Hope it helps

They look rather nifty

got mine from Halfords!

I got these from RS Components.
There are five 0.002" feeler gauge strips about one foot long.
They cost £10.49 with free carriage.
You can get them in most thicknesses and at this price you can experiment by cutting or bending a few till you get the perfect shape.
