NOW I HAVE A MACHINE BRUSH
HO HO HO
Technically I already had one. Believe it or not, that £20 Timbertech airbrush is an upgrade from this pos:
Testors Aztek A270, single action, siphon feed. Used for one basic job (colouring wooden letters for a toy box) and put away for years. I dug it out again and thought 'is it really any good?' I found a
single comparison-cum-review, on youtube, where I realised all the spattering and spotting from it wasn't just me being a noob. Whereas the Timbertech was reviewed by guys used to the big brands, and the reaction was almost universally 'wow, this is really good for the price!'
Next day delivery with amazon prime (there are slight advantages to shovelling more money into Jeff Bezos' pockets), survived where the crack amazon delivery driver dropped it over a fence onto concrete (I think

), but first test is going to have to wait a day or two.
Maybe next year I'll get that three-figure Iwata. Until then, I have a feeling the biggest needle that comes with this will even let me spray gesso on boards. Groovy.
Also: wow, you don't get much for six quid. Oh well, as long as it's reusable.
