So thankfully it appears I've managed to fix my airbrush. Modified the power connector, improved ventilation for the motor. and Cleaned out the filter. The only issue is it now has a whistle that wasn't there before. Despite this, tonight's stream was good. Not many viewers but I got more progress on my primary project.
Things are coming along. I have to keep reminding myself to slow down. I'd hate to make a royal fuck up now.
