Lol DIYSwede. I'm convinced toolmakers of various experience/ different statures rework inferior tools all the time. Achieving setups for a one-off project teaches creativity and forethought. When you get down to it, that is what separates a machinist from operator.
Buying first rate has some satisfaction, but less than applying process remedies to cheapo facsimile tools. I have a good precision level, a rescue as well. Not the complications of yours though.
I like your "assembled kits" labeling. Another that really entertains me is "_________ shaped object". Insert noun of choice. First I recall, someone derided an import lathe full of faults, with coup de grace of "lathe shaped object".
Seems long ago, but tickles me still.
