Looks good.Did you coat it with something after the blasting or just leave it?

The water/hydroblasting i had done was great.. It gave a mild polishished finish on a yz125f swingarm. It actually peens (if thats how you spell it) the alloy as it blasts, therefore not allowing dirt to get in the rough casting of alloy. We have had many things done and it makes it so much easier to keep clean i have found. The guy i used is an old car restorer engine builder around Sandringham in melbourne.

Hi Al. Greg Wood's contact details: 12/20 George St Sandringham 95970387. He did my head, barrel, inlet manifold, cases and rear hub. I can't speak highly enough of him. Excellent quality, realistic prices quick turn around and a good bloke to boot! I think I want his babies! Jerry

Woody is a top bloke. He's a perfectionist and his prices are excellent.  He did the entire engine and carb on my XR75 and more recently, the barrell/head/triples/carby etc for my RM250B.  I dropped in there today and his wife (Louise) did 3 alloy brake levers for me on the spot.

Soda blasting is an alternative and also very effective. As long as you have a decent sized compressor you can set up at home for under $400 which, although a bit pricey, gives you the flexibility to do what you like when you like. The blasting medium is perfectly safe to use and doesn't mark or harm rubber, plastics etc. The process leaves behind a residue that can be cleaned with warm soapy water. Ideal for doing an engine without disassembling it - just tape up the holes and away you go. Any soda that does find its way inside can be just flushed out when finished. A 25kg bag of soda is about $75 but goes a long way. I've got one set up at home and am very happy with it.

HOw do you Contain it ? or is it something you just point and shoot
Title: Re: water/vapour blasting
Post by: yamaico on November 11, 2009, 12:42:41 pm
It's contained in a sand blasting pressure vessel. You can't re-use it as you would in a bead blasting cabinet, so yes, you just point and shoot. The soda breaks down when it hits whatever you are blasting, so it couldn't be re-used regardless.

Freaky, I've soda blast some of my frames outside on me lawn . As Yamaico has stated 25 kg will go a long way  ( 2 frames easily )
To answer and earlier question by "motomaniac " there is no need to spray a protective coating on after its been  "vapour blasted "

When there is a need  for clear coating over, I use outboard clear acrylic ...by K&H
