Soda Blasting
« on: November 03, 2014, 19:05 »
Long weekend with nothing much to do so I thought I'd have a go at soda blasting.
Much like sand blasting but using baking soda (bicarb) which is much softer on delicate items.
Google will bring up a lot of information about it.
Here's a rising sun  badge I had a go at.

I used to do a bit of sand blasting as a prepaint step at a small foundry back in Castlemaine.  I have loved the process ever since (though I haven't made a home unit as yet).  I love that you can get into nooks and crannies and have no grinding marks/scratches and depending on what you are using to strip the stuff leaves a nice textured finish without that smooth gloss that sanding leaves behind on flatter surfaces.

I have a small home unit and use soda or tiny beads to clean brass and other items from coffee machine; service or rebuild.
The soda worked well for a while until a bad storm and water got in... LOL.

My setup is basically a cardboard box with a plastic top, a tube to suck the soda up from a plastic jar, and an air line from the compressor.
Not fancy but OK for a trial run.

Mine was from a tool shop.. And made the plunge after I got a non working compressor and implemented a simple fix...

Thus one compressor for cleaning and general stuff and the repaired one, out side with the wood lathe and Sand Blasting unit.
