Thanks
@huskystafford and
@clutch for the tips. Appreciated.
Yeah, the paper towel practice is boring, but I have more fun with that than with the newsprint flipchart lower-pressure practice; I do both, warming up with drawn out lines (usually just like Daniel shows it), then I do vertical and horizontal lines (assisted and unassisted with a finger post - to work on that freehand shakiness), and then I either do shapes with fades, or daggers or both. Then I go off on the paper towels. I have a good time and I know why: it's easier to flow at higher pressures and absorbent materials. Just recently, I picked up a book on sign painting from the library to see how different styles are done, so that's been inspiring and informative as well.
My biggest struggles thus far (since I stopped using india inks to practice - which is what I started with in Feb and switching to Createx) is getting the paint to spray consistently without sudden blow outs... I'll be going along fine for a few loops or lines and then... ffffttt!!! small spider out of nowhere or my pencil thin line suddenly gets fat and fuzzy... Tip dry, yeah - but that's not the biggest annoyance. I've got in-line filters (moto-guard and a regulated moisture trap downstream, as well as an end of the line airbrush hose inline filter) and still this happens. I even had a coalescing filter set up, thinking it might be oil vapour from the silent compressor getting in the line, but the moto-guard filter made that redundant and it didn't seem to make a difference anyway.
I'll re-read the posts that
@Ronald art made about psi and paint, but I think I'm in the right zone for the Iwata HPCS and BCS (higher, for the latter, per Iwata's specs), but I struggle with consistency and spraying lightly. I also figured out that it's waaaay harder to paint Daniel's "hands" exercise at 8.5 x 11" size vs. on a 2 x 2 foot sheet... Yeah.
BTW: just watched a documentary on an old Tattoo artist, named Norman "Sailor Jerry" Collins
: Hori Smoku Sailor Jerry The Life of Norman K Collins Documentary (I'll bet my Paasche Talon

you guys know who this is...). It's pretty fascinating and the intro song is hilarious. Anyway, it got me thinking about lettering ideas and that led to paper-towel practice of 'tattoo style' letters and stuff, but the blow-outs... grrrr.
I'll see if I can post some pics.
Cheers guys!
