Most people, even tho they are very mechanically inclined, simply don't use measurement tools that give finite readings to an ideal precision; case in point
using metric feeler stock, or feeler blades with 3 decimal place precision, and calipers or micrometers with the same 3 decimal place precision, can only "assume" what they read out is "real"; then they haave to base the readings on "did it feel tight, or loose"...
I've said before here, that an economical micrometer, delinated to 4 decimal places (.xxxx"), when used correctly, actually can offer great amounts of clarity on the actual dimension. Combined with again, very economical precision "feeler blades/strips", also combined with being "stacked, and measured to verify", give the same results in judging clearances...
It takes the guesswork about "is this dimension .0002" or .0008" off" from the nominal 3 place dimension.
Individual feelers and also the micrometer which I purchased from McMaster-Carr, only totaled me about $50, and as in my industry I could have the tools verified thru our calibration people.
Then, when happy I am working with good tools, adding in the ability to measure and swap the individual buckets, and seeing the span of deviation on those particular parts, the ability to swap around those along with my shim map, gave me extreme flexibility, and minimal shim purchase expense; while still resulting in meticulous readings.
Opening up the engine, and going thru this does take time, and an amount of patiance and skill.... but in the end, I don't really want to say "it's good enough" when I know the measurements may be "iffy" on my bike.
I'm sure what Max came out with is fine, and will not result in a catastrophic failure; Haroldo proved that it's all possible, with some essence of magic.
Congrats on the job Max.
