Cleaning metal parts

[Scotia]

I have a pressure pot similar to what Trev posted, I used glass bead at low pressure but no water and also soda for finer parts. The vapour blaster produces a great uniform finish. This was the state of a Ducati I picked up that had lay in a leaking shed for 30 years.

I know of a Porsche specialist who would use ground up walnut shells to blast the intake ports free of carbon on the V8 928 model. Apparently it was a common problem and Porsche would want to whip the heads off, he did it all insitu.

Worked for a Glass Recycling company. We used to sell Cullet (powdered glass) for blasting.

Steve did you coat or seal that step or is it just raw ?.
As I'm in for polishing my ally that's on show in camper and looking to seal it so it keeps a shine. But at a loss to how it done ! ?. Any help is help.
It a step up, and looks a good job done. Mate.

Years ago I was up the Forth Rail Bridge on behalf of RigBlast. RB had the initial contract to blast and repaint the bridge. Massive job with worked on areas totally encapsulated to mitigate blast media and lead within the 100+ year old bridge entering the sea and homes each side of bridge. The media they were using, and at great pressure, removed the old paint quicker than a Leith hooker could remove her knickers

I’ve got some serious dangle berry’s that even that shot blasting machine wouldn’t budge.

Loch Katrin is good for getting rid, give it a try!

Wully, get up on this roof, steep as pitch, which will sort the dangles from the berries.

Pressure is around 100 to 125 psi, its the volume which counts, 200/250 or even a 360 cfm compressor,all depending on the nozzle bore, they would have been using J blast which looks like black heavy sugar, its the ground down slag of copper smelting.

Vapour blasting is really good but for a better finishing I would want one of the scanning laser cleaners, trouble is the price as the decent-sized ones are in the many tens of thousands of pounds, it cleans turbine blades and similar without dimensional changes or damage
