You cob blasting there Jon? How much of a mess does that make as opposed to the wet method ?
I hope these hood guys enjoy us hijacking their threads with log talk
That is not me, I don't like blasting Too loud and hot for me! Actually we are using walnut shell--and yes I like the blasting process, clean and not leakage. Pits the surface and gives "tooth" for the stain---not great with oil stains though. All in all, it has advantages and disadvantages, you can call me sometime if you guys ever need to try it, jonathanmarkfife@hotmail.com

John,
My guess is that it would be awesome for results, but bad for logistics. You have to have a 185 cfm compressor to run this....that is the kind you pull behind a truck. And you'd make a pretty wild mess indoors. But I am sure you greasers have ways of dealing with the interior messes. As far as results, sometimes we use corn cob media, and that won't etch or nick glass or metal, or basically anything but wood. So it would clean off your gunk and leave the metal smooth. I am sure soda would be the same.....harmless to metal, and perhaps you guys rinse once done to get rid of it?? Like I said, the machine I have would probably be overkill for you, but the application would be great if you could find an adaquate machine that was smaller.

Jon,
In your photo are you sand blasting, bead blasting or what?
Is there a big difference between bead blast and sand blast? The stuff they filled the hopper with looked like sand to me....but it wasn't.
You are right about the mess, and the trailer. They had a big trailer and a big compressor inside..... There was a mess but they vacumed, swept and then hosed everything down nicely when they were done.
I saw a CSI where crews were cleaning statues in Central Park with walnut shells......
This whole process (the bead blast) was very interesting to me Now I wanna know more.

Now I wanna know more.Chris,
We are using walnut shells in this pic. That is more abrasive than cob, since it has sharper edges. For us, corn works for some apps, and for tougher removals we use the walnut. See, the thing I have to think about is biodegradability, since we'll use around 40 bags on a normal home and obviously cannot clean it up. So we clean what we can, and the rest becomes mulch. Sand is more abrasive than walnut, and glass is probably less abrasive. But with glass, if you are in a humid area it will clog the moisture separator since it absorbs moisture (i guess). You said on CSI they used shells to clean statues......that is because they wouldn't want to reclaim their product. In selling, i push the environmental safety of the blasting. In truth, the thing I like about it though is exactly what you said......everyone is interested in it and stops and asks questions, makes good publicity.
Oh, and if you guys do it indoors, you'd have to have to whole respirator set-up, that'll run about 3-4K more. I'll probably get one here soon, it makes the blasters life a little easier when cool air is being circulated.

And Chris,
.....Regarding the compressor, if it was in a trailer it was electic, like you'd see in a mechanics shop. From the look of your photos, that blaster they are using is probably 1/10th the size of what we use. We rent the compressor, it is diesel and BIG. The hoses are inch and a half. This winter if I find the Chevelle I'm looking for I'll get to strip it....that will be fun.
