Oops.

One of those “this should be a quick job” ideas that keeps getting more complicated.

A while ago I bought an inline duct fan to get better airflow for my spray booth. The original fans seemed to be getting in the way though.

“I know. I’ll just remove them.“

Mistake.

After taking it all apart, the wires had to be cut as they’re soldered in.

Then I had to get something to cap the wires off.

Then I realised the outlet hood was screwed to the fans themselves and there’s nothing to screw it back onto anymore.

Now it’s night, the shops are shut and I can’t find anything in the house to help me fix it back on.

Lunchtime trip to B&Q/ToolStation tomorrow I guess…

After all this, I really hope it works or I’ve just ruined a decent spray booth.

The good news: I managed to pre-drill some squares cut out of a 3D-printed paint rack, glue them to the underside of the screw hole and they held well enough to re-screw the vent down.

Also good news: the lights still work!

Less good news: almost no noticeable difference in suction from the inline fan.

After finding a very complicated but comprehensive article (https://www.modelersite.com/Abr2003/english/Spray-booth-design_Eng.htm) about calculating airflow and static pressure, the fan I have just isn't going to cut it, so I've ordered one twice as powerful in the hope that'll do the trick without now being super noisy (it claims not to be).

This is the classic "can't afford to be cheap/poor" problem: buy cheaper fan, get bad results; buy slightly less cheap fan, maybe get better results... possibly end up paying more than just buying an expensive item in the first place. #MiniaturePainting #airbrush
@minis My favorite version of this is the Vimes Boot Theory, because Pratchett. https://en.wikipedia.org/wiki/Boots_theory
Boots theory - Wikipedia

@roofuskit Yes! I was aware of that and also a fan but totally forgot it when writing my post. Pratchett probably had a good name for that too...
