I think there are two parts to welding memory. The first is mental memory, like welder settings, and where you put your favorite gloves. The second is muscle memory; the feel and position of the torch and filler wire, and the orientation of the workpiece. Muscle memory really takes over when you have a puddle in front of you.
For taps, take a look at these:
YMW are by far the best taps I’ve ever used in 6/4. There are razor sharp, but brittle. They break relatively easily with a side load. The Sandvik ones are more robust, but more expensive.
Great project!
