I am currently working 3 days /week for a company who make high pressure (160bar) water hydraulic pumps/motors and valves and air motors. We were badly flooded in December (1.2 metres of river / sea water) and the MD is buying a SH bead blaster to try to recover some of the rusted carbon steel components (the water hydraulic components are made from 316 ss so OK). It occurred to me that since we have two massive air compressors for testing air motors and make high pressure water pumps, it may be possible to make an aquablaster so that I can clean up all of my bike parts!! Anyone know how they are constructed? They are really expensive even second hand (around £10k compared with a bead blaster , around £2k).

Ash, aquablaster is a mixture of water and silica sand or grit and other media. we use them for cleaning old buildings and bridges. You can get smaller ones but, the one we use runs of an old fair ground compressor. Not good for cleaning bike parts. For bike stuff i use a soda blaster for paint and metal stripping. For engine cleaning ,a vapor blasting machine does the trick.
There is a post on the states site that shows how to make a homemade soda blaster.

Aquablaster looks like very high pressure with very little abrasive. Just done some googling. Trigs suggestion is a good alternative with very little outlay.
You could scale this up with your big compressor.

I was just nosing around over here and saw a building with a sign showing old cars being done up.Curiosity got the better of me and in I went.Here they call it feather blasting not heard of it b4 but the results on frames tanks etc was unbelievable.Came out like a baby's bum smooth and showed all the welds etc and rotten bits.The painters were over the moon because after that no rubbing down etc and I have to say it did come up bloody good.On the frames you could see any rot holes with no problem at all in fact the guy showed you everything he did not like the look off.Tried a 400/4 lump with it but sadly no good for engines did not make a blind bit of difference.Has the UK have the equivalent?

Feather blasting equals what?
Looks like google is getting another thrashing.
-
Bitsa, what is with the French and feathers? You have french maids with feather dusters, can can girls with feathers and now you are trying to tell me about cleaning metal with feathers. You are having a laugh.
-
That's the problem Lester I dont know the fuc off size cabin he did it in on the floor just looked like someone had plucked all the turkeys for Xmas for the UK,but man I mean real smooth used it twice same results.It removed all the decals,rust and all but like I said I don't know.In the UK must be called something else can not be unique to these doughnuts.I did notice a word which might help DECAP!!!!!

DECAP! Headless chicken cannon? Must look into this.

Got this from the SOHC.net USA site.
Here in the states, there's a gentleman who specializes in Vapor Blasting. He describes the process as having started in the UK post WWII and that much like bead blasting, is a specialty mixture of slurry and plastic beads (if I recall correctly).
Here's his site:

Thing is that in the floods two Ultrasonic cleaners (one Swiss made that just cost £2k) were written off but me being an electronics engineer you don't need two guesses what happened to them. So with an aqua/vapour blaster I would be well set up for restoration.
Also got a large bench grinder with Scotchbrite wheels on it that I managed to fix, just needed 2 bearings. BTW those Scotchbrite wheels are magic for cleaning parts.
A £20k Camper van and an immaculate £15k Rover P5B Coupe were also written of as cat A Plus a modern Merc. Insurance paid out fully on agreed value. Business back to normal now fortunately.
I had a Mitsubishi car with a GDI engine, they used to coke up sometimes within the warranty period (due to our higher sulphur fuel) and Mitsubishi blasted them with crushed walnut shells to de-coke them.

High pressure shit. ;D

Ash, vapor blasting is a finish. If you are going to paint a part there is no need to vapor blast it first. I do engines, so they come in different levels that need cleaning. some i can get away with soda blasting but, they are non-finned engines. The rest start off in the wash, then get bead blasted. Then it is down to customers requirements.
Aquablasting will leave pitting in aluminum.

So Trig for cleaning up engine cases heads wheel hubs, am I better off with 'dry' bead blasting?
Cheers ... AshD

Ash, it depends on what kind of finish you are looking for, and what state the metal/aluminum is in. I had the idea of blasting up a hub, to get it ready for polishing. Used a load of different media but, just could not get it to the finish required for polishing and ended up painting it. A lot of people take parts for vapor blasting, not understanding that to vapor a part, it needs to be totally cleaned first.
Dry bead blasting is ok. If you are going to paint after or example: Bead blast a head before vapor. If aluminum wheel rims, then soda blast before polishing. Hubs are a sod, and would commend paint in the form of powder coat.

Cheers for advice Trig. The engine parts will mostly be painted so surface finish not a real problem. My main problem is getting wheel hubs and fork bottoms to look like they were from the factory. I hate highly polished finish on classic Hondas, it just doesn't look right. Originally they were like a brushed effect with clear coat on top.

Found the site take a look all in French though

Bitsa, did not see any feathers or go go girls :'(. That is bead blasting mate.
-
If you use Google Chrome it will translate that page.
-
Lester,
What did you think? I did not think it was normal bead blasting the stuff I saw was like the feel of feathers very soft and no pitting on metal surfaces as I said the paint shop guys were over the moon with it.
With usual bead etc everything came back with bits all over it this does not.
Cheers
Bitsa
Trig ever been to France?If you have I bet it was to see the moulin rouge.
-
Sorry Bitsa, France is not for me. Even when i drive down to Venice or Ancona to catch the boat to Greece, i avoid France. Did work in Nice when i was 16, selling ice cream on the beach and being chased by plod.
There are so many different types of bead these days, even poly bead. Very soft.
-
It could be any sort of poly media as Trig says. I mean walnut shells are even used so anything goes really.
-
Les, i have a blasting media book from a supplier that has 24 types of media per page and has 38 pages. Try Peppercorns or Ceramic beads in 124 different grades.
-
Trig,
I love the country but hate the rest,there is good and bad with all countries but here frustration is the big no no for me.Nothing is simple here.The best is price of booze,no road tax and no MOTS for bikes.I think thats about it.

I used to stay in a Gite in a Brittany village about ten years ago. The last time I was there they had this village fete thingy and invited us to go along when I was in the village store. When we arrived they insisted on my family members all sitting at separate tables so that we had to 'mingle'. There was something special about it, a real sense of camaraderie among the locals, that you just don't seem to get quite the same of here. They all took their old farm machinery and paraded it like it was a pristine 'E' type. Nothing was restored just like 'barn' finds. I was like something from the 50's in the UK. I guess you just have to accept their idiosyncrasies and try to integrate as much as you can.

Ash,
Been to Brittany and you are right.Where I am it is nothing but farmers who think a good time is a bottle of wine and to feast at the spring fair on a giant omelette.After 14 years of it can no longer stomach it.Will soon hopefully will be moving on to a busier part or back to blighty.Also they all have the biggest and newest tractors I have ever seen and they portray themselves as skint!!!!!!!!!!
