I wasn’t happy with the performance of the HF detail HVLP sprayer, the adjustment knobs were hard to turn and the spray seemed to pulsate instead of a steady spray. Maybe it was a lemon. I upgraded to the more $$ HVLP Touch Up spray gun. For under $40 it works great.
I made a new batch of Ti/Tempera Juga but used a little more water and a little less Tempera. The recipe was 10.5 g TiO2, 40 g H20 30 g Tempera.
I bought a WalMart coffee frother $5.99 that worked really well to mix instead of the drill-mounted wisk (remember Tim Allen, Tool Time, Binford 5000 ha).
The HF HVLP Touch Up sprayer works like a champ. In my opinion it is worth the extra $$. I burned some images in grayscale mode which is the hardest image mode for me to nail.
Nailed this one on the first try
The left beetle was with the IPA/TiO2 recipe, the right one was with the Ti/Tempera
Tried 3 variations on cut settings, either too light or too dark
This was a photo from my cell phone maybe could be better but not bad for first try, especially with grayscale.
I know cut settings are unique for each laser but at least the coating formula can be shared. I don’t think any of the Liquitex airbrush BS additives did anything so I will omit for laser and leave it to the airbrush painting endeavors. I am trying for a minimum of 15% Ti up to 20% in the recipe. My juga gets like cake batter at 20% and it is hard to mix and spray at that point. My laser is an XTool D1 10W.
If anyone has any tips on optimizing grayscale IM, I would appreciate all the help I can get.
