True Grit!

Melissa is lost for words, but with this many images, who needs ’em anyway?

or, what goes in must come out.


Grit. Goes in. When spent, gets vacuumed out again, ends up as dust in white bag. (Like the warning says, be sure to wear appropriate dust protection.)

BUT

In the middle section – you know, between in and out – it gets used to BLAST!

Once grit is in, is falls to the bottom and waits to be cycled up into the nozzle. To get to the nozzle, needs compressed air (as in yesterday’s post). To have vacuum on, and see what I’m doing, needs power.

All that, and I’ve not even changed the grit!
