Dry ice blasting.

[1650bullet]

Just want to know if anyone has ever heard of this method and what do they think. Im thinking it would be a huge + for bringing alloy parts back to an original finish again. And theres no grit thats left behind (like sand or soda ash)because everything just evaporates and would be ready to assemble. Its a 6.50min film. But it shows what it does to a motor car cyl head and gearbox.

Strange you should mention it Bullet and what a coincidence.
After lunch in Ottawa yesterday with my wife and while waiting in the parking, I noticed a van parked on the other side of the street with the lettering "Dry Ice Blasting."
I immediately thought of its use for Seagull restorations and felt like posting it on our forum this morning as a suggestion. To my surprise upon opening my comp...here's Bullet with the same topic!
I guess great minds think alike thar mate!

Like some of you I own a compact sand/composite blaster reservoir that connects to a high-pressure air nozzle, and have used it many times with succes (on non-Gull items), but as you know it makes a hell of a mess and clean-up is a drag. Then when you notice spots you missed under a better light, you have to go at it again. Dry ice blasting sure sounds enticing...and to re-iterate Bullet's question: has anyone actually tried it on Seagull parts?
Cheers!

david. One thing you wouldnt have to worry about is taping of evrything to keep the sand out because the dry ice would just evaporate and leave no moisture behind.It certainly brings the alloy back to new again.

Very interesting for sure...looking forward to follow-ups

I've heard nothing but good with this process. For those who have not seen it here is a video from you tube. On contact the dry ice explodes and blasts the muck off.
