So i bought this from the restoration show a couple of weeks ago..... wanted one for years and finally got around to getting one.
I'm currently using crush glass blast media which is great on rusty parts but a bit severe for alloy..... it will probably calm down a bit once it's done a few cycles through the gun and broken down a bit but I want something a with a lighter touch to do my inlet manifolds....
Anyone else got a blast cabinet and what blast media do you use and for what? Any handy hints?

OOOoooohhhh fancy. Seems like one of those things that would be very satisfying to use.

I have had no experience but I have read that ground walnut shell made a good media to use.

I've always wanted one of these. I checked them out at the NEC Classic show last week. We have a good one at work but unsure if I'll be allowed to use it for my own stuff hahaha. Got any pics of before/after blasting?

Ooooooooooooooh, nice - I can't help with your query Ian, but I keep looking at getting one of those. Be very interested to see how you get on with blasting an alloy piece.

Bead blasted the alloy inlet manifolds on the elford then clear coated with high temp clear. Still looks good 2 years later.

did you use glass bead or plastic?

Glass beads I think. Gave a nice finish.

I've heard that some companies use crushed walnut shells where they don't want to damage items, also some form of soda is sometimes used which is softer.

I used these guy's for my car, but surprised to just see that they have ceased trading.

Couldn't resist a "VAT Free" voucher offer at Machine Mart and just lugged home a Clarke version of that cabinet. Might be a while before I can set it up fully, but I already have a bench full of rusty parts that need attention and doing it with wire wheels, etc, was getting to be a chore!

walnut shells are used for rumble polishing, I'd have thought a bit soft for blasting.
