I have to say, I have a Russian 91% and those screws are pretty tiny and hard to work with sometimes.
Yep... they are. I have Kruss "Triplet" stereoscopic glasses that make them much easier to see. FT has some cheap and ugly, but effective glasses that I understand work quite well, once you get use to them.
I also have a magnetic jewelers screwdriver that holds the screws nicely.
With a KFL/R91% style atty, wrap the coil so it sets on the deck at the 11/5 o:clock position... then with a mandrel to keep the coil stable, use small tweezers to pull the tails tight around the screws and back toward the coil.
and some times the positive post gets loose during a build.
New KFL/R91% type attys (clones more so than genuine SvoeMesto KFL+/ Kebo R91%) will compress the positive block insulator over time and use.
Disassemble the atty, and after cleaning and drying all the parts, reassemble... holding the positive block with pliers when tightening the air tube/screw.
but the performance is so good, I can overlook those impediments.
