Adjusting tappets
McCabe-Thiele (Ted):
I was worried about sump dilution when I rode a 100 mikes on two cylinders! Lol

Has anyone used this tool?

Tools like that (there's been a few design over the years) work OK but some prefer seperate. Makes it easy to hold both parts if access is restricted too.
Shouldn't be a problem, but as with most things, comes down to personal preference in trying it out.
I find it easier to finally tighten tappets by letting the cente rotate with the securing nut for that final torque, as opposed to holding the centre absolutely still as the threads tighten on each other in conflict.
Easier to do than describe ..... but would loosely approximate to aiming for a marginally wider gap than needed, only to let that close slightly with the final tighten to then arrive at correct specification to be checked and verified without touching the locknut again.

And you manage to get 0.005mm of clearance precisely? Doing it the way you describe I never could, that’s why I went for that tool Sean showed. Kudos to you

;D that was my second job as a kid, so long time practicing.
First was given a little brass brush and feeler gauges to clean and gap spark plugs when my father worked on our family car, dont remember if he actually used the plugs, or it was just to keep me quite and out of his way. Did feel quite grown up with that responsibility though :)
Then on to tappets as I didn't mess up the plugs.
Taught me to weld at about 12 years old too, all oxy /acetylene then as well.
