Most stuff out there is geared towards t-shirts which can take a coarser thread screen because it soaks in the ink. It's not difficult to stretch and treat a screen, just time consuming. So far, it takes me about a day to make a screen with in between drying time included. I've learned there is also some technique to coating a screen with just the right amount of emulsion.

Thanks!
By pre-sensitized I meant light-sensitive. Basically, you buy a screen that is pre-coated with a photosensitive emulsion, correct? This vs coating the screen itself, then "sensitizing" to activate the photo-chemistry.
And I can appreciate the effect of mesh size. Some of my wonder years were spent in a lab making prototype microelectronics. We screen-printed "hybrid" circuits so I've got some of that in my two remaining youthful memory cells. We also did a lot with liquid and dry-film resists. It was interesting, just like what you are sharing!
Here's the last time I thought about the gauge graphics. I have a dash tach I may play with if I run out of elder interests... your success might motivate me!
