Having heard the prices to blast a stripped C10 cab...... £310.00 for bladting alone at mates rates, I have decided to build a cabinet myself (as long as I can find a pair of those thick looooong gynaecological gloves you use to hold stuff with) A 20 gallon resevoir is around £120.00 delivered and I have a 100liter/150lbs per square inch Broom Wade compressor. Should work OK.
I will Goigle it in a bit too, to see just how easy, or not, it is to build a cabinet.
Just looking for tips before I figure it out by trial and error.
Thanks.

You need a huge compressor for continuous blasting. A small one might be OK for a small cabinet and doing small items where the compressor has time to recover between trigger pulls but you should be thinking along the lines of road compressor for doing something like a whole vehicle cab. A 100 ltr is nowhere near big enough - sorry. Blasting is an absolute horrible job. When you weigh up cost of blasting medium, electricity, hire of suitable compressor etc then the £310 isn't a bad price. I want a set of five Grand Vitara wheels blasting and powder coating. I've been quoted £60 for the blasting and £40 for the coating. Company apologised for the quote but said the blasting is the most labour intensive aspect of the job and is reflected in the cost.
Can't you paintstrip the cab then localise sand blast the rusty areas ? Would be a lot easier and your compressor might capable of such short bursts.

Grizz , wouldnt you also have to build some sort of frame and cover it with polythene as well to stop it going everywhere? Another item to add to the list .I'm pretty sure , as above that you either need a huge stationary compressor like one built in to a workshop , or a rental one like road workers use for jackhammers . And you need a air fed hood etc . Sorry but its £££££££££££££££££

We have a blasters who occasionally 'tart' up our skips when they get a bit long in the tooth. They use a 175cfm diesel rd compressor to provide enough pressure/ air flow.
Then of course you have contain the blast medium and dispose of it.

Thanks for all the replies guys.
I am not getting my cab blasted but mate Martin will need his done.
My compressor may well be able to do smaller items in a cabinet.
Martin will have to make some closed in cover to do his cab.
Luke, thank you. Will see what the next week or two throw up.

In the past I used to maintain a couple of large blast cabinets, which were handy for the odd homers. If you are going to blast just the cab, I would say go for the 300 quid job. By the time you add up all the costs of diy, compressor hire, gun and grit purchase, blast hood etc, etc, the price won't be that much of a saving. Blasting is very time consuming, imagine painting the cab with a 3/8 brush. Also very dirty, the grit gets everywhere ! Also a word of warning, there is a risk of explosion with an enclosed cabinet. I did think of diy blasting my beetle pan, decided to stick with angry grinder and twist knot, time taken will be about the same, cost will be less, setup time zero but about the same amount of sweeping up afterwards. Or maybe I am a bit deluded. Ttfn Glenn

the thread on volkszone.com seems to have given some pretty epic ideas: these plastic drums can be had for pennies - and would stand up the media blasting quite well. The comment about adding a dyson cyclone stage to the dust extraction is genius itself Again, there was also a comment about stitching some old jeans onto gloves to make some budget gloves. I'd potentially want to use welding gauntlets, as it would also be useful for stopping sparks flying up your arms An idea I've been toying with for a large air compressor - is use the same techniques used on early portable railroad compressors. They simply used an air-cooled Fiat engine (IIRC)and used 2 cylinders with one way valves in the spark plug holes. Probably ran quite lumpy, but you'd just scale it up to have one engine, driving a complete donor engine (big v8 or similar) to use as a compressor. Share the sump and coolant, to ensure the second engine won't wear out from cold oil

Beetle engine as a compressor. www.dunnrightinc.com/Was told once someone used 4 cylinder diesels as compressors 2 pots driving and 2 pumping. If using a petrol engine, make sure no fuel mix gets in the air side or one spark and you will have a diy flamethrower. Ttfn Glenn

I've got a Machine Mart blast cabinet but I use an old Kirby Heritage industrial vacuum cleaner for the extractor. The bags are cheap as chips and very strong and I get no dust anywhere in the garage. Prior to using the vacuum cleaner dust and lack of vision to see what I was actually doing was quite a problem. I do like the temp greenhouse idea though for doing bigger things outside, never thought of that, genius!

Picked up some packing crate sides today, hope to make a cabinet, albeit a bit big, for the blaster today. I will line the inside with some thin ply sheets from other packing crates. Then out to scavenge for an old vacuum cleaner I can build an extractor from.

A pressure pot is the best system, but for a cabinet build you may wish to spend some time on a syphon pick-up of your own,. I lashed up a cabinet last year and the volume of media flowing was intermittent and even when it did flow continuously was low flow, I made an air assisted pickup with a 1mm orifice, which agitates the media and blows it up the syphon tube, it was a massive improvement and over double the flow. If you're interested I'll try and grab a picture This thread is where I cribbed the idea, but mine doesn't require drilling the outside of the hopper, Cabinet buildOh an gloves are available with long sleeves on eBay for about a tenner Brian
