Will be keeping an eye on this thread with interest, been also looking at purchasing one of these to tackle a crusty t2 camper. Curious as to what kind of effective diameter you get from the nozzle wouldn't fancy doing a complete vehicle if it was only 10-20mm for example. Also are they any good with hard media and is it easy enough to change over.

They come with the necessary nozzles, etc for hard media. Am I correct in thinking that soda wont remove surface rust ? Do you need to use crushed glass for that ?

I wouldnt waste your money with one bud! They block and moisture trap so badly its unbelieveable, you'll spend more time unclogging them. Also having a compressor that can supply the air demand constantly is an issue aswell. Nothing worse than getting into the job for it to runout of air and leave you standing there for 10mins.
Soda will remove surface rust but isnt abrasive enough to tear it out of the metal. Youd want glass for that sort of thing.

Total waste of time. They are designed to do a small patch about the size of your tumb at a time. To do any meaningful blasting you need a proper pot and a massive compressor. Even then its a horrible job. If ever there was something worth paying to get done for you this is it!

yeah you need a massive compressor
anything more than a couple of brackets its best to pay to have it done

After the comments above seems the miller unit is no good, I have been doing a little more looking around and came across this one: www.ebay.co.uk/itm/SAND-BEAD-SHOT-SODA-GRIT-BLAST-BLASTER-BLASTING-MACHINE-POT-SANDBLASTER-TRAP-/201275709820?pt=LH_DefaultDomain_3&hash=item2edcf7997cLooks good in the attached video and although it is twice the price of the miller unit hopefully its a case of you get what you pay for!! As I said earlier I have a full VW camper shell I want to soda blast, not to mention all the drivetrain components I will be wanting to do so need to find some kind of solution and I am also in the process of opening a garage so could be an additional service I can offer. Plan on speaking to the company and see what the recommend for the application I'm looking for.

If you really hate yourself and have a large three phase compressor & drier to back it up, then by all means go for it. If not, just pay someone to do it.
Youd have to be really glutten for punishment to want to blast a full size camper..... personally, i would just blast the underneath (in which case you need something a lot more abrasive than soda to remove the rust. Somethign like crushed glass (cheap) will work, but aluminium oxide (approx £1/kg when you 1t at a time) will be far better. then youre going to need grading equipment or at the very least a bloody good seive to make sure you don't get any debris mixed in with the grit when you run through it a second time......
Also, bear in mind, with the propper kit, blasting a camper is about 2 days (16hrs) worth of work....
don't forget youll need a proper helmet and breathing air set up to go with your blast pot. This needs to run through proper filters as well, otherwise youll end up breating oily air, which is not great for you...... Also, make sure the compressor is sited well away from wherever you are blasting, otherwise youll kill that too!!
Realistically blast cabinets at home are fine, but kit like this has no place unless you have a proper place/set up for it, which is gonna cost WAY more than getting the bus blasted by someone else.........

cant your blaster give you an estimate of hours required?
other things to consider, soda as a media is expensive, wont remove rust, however i saw a twin pot set up which would allow sand to mix with the soda making it more aggressive, think it was eastwood/frost IRC
i saw the video of the second pot you posted, i highly doubt that soda is the media in the video, in any case it is a proper compressor, powering the blast pot, i've also looked on their website and the airfed mask, hood, filter get up is £430.
as much as a blast pot and the ability to blast stuff would be a handy addition (i've looked long and hard) wouldn't paint stripper be the solution, for the op?
oh, and crushed glass as mentioned above is a lot cheaper then soda and less likely to damage panels then sand and it'll remove some rust as well

I have the dual blaster. www.eastwood.com/dual-tank-blaster.htmlIt has two tanks so you can switch between soda and grit on the fly, or even have a mix of both. The problem I find with it is that the compressed air has to much water vapour, even with two traps. This means your soda gets damp and turns into one big lump of clag in the bottom. It's a pain, I have to keep shaking the tank to get the soda out!

I am just exploring every avenue to save a bit of cash on my resto. I might take a look at paint stripper, definitely an option. Or I may just have to shell out on the blasting and stop being a tight wad !!!!
I blame the Mrs who keeps saying "How much are you actually spending on THAT car !!" and of course I keep saying "Not a lot, honest !!" You lot know the score !! ;-)

mdh, are you using copper pipe from the air compressor? before the blast pots, i presume you have 1 of the water trap's fitted just before the blast pot, how much are you buying your soda for? and yeah 1eighteen i know the score, i find it best to get unknown cashback when i used to do the shopping for unexpected purchases

Copper pipe? You mean between the compressor and blaster? No I just use ordinary air hose. Yup the pot comes with a water trap built in. My soda came from eBaY and was stupidly expensive compared to other media. SodaI'm thinking about trying crushed glass instead of soda, but I need to fix my compressor first.

as i understand it, running copper lines with a slight incline cools the air considerably and allows the moisture to roll downhill hopefully to a leg which would have a gate valve after the pcl connector which you'd open occasionally to let the water out.
its still on my mental list of things to get sorted in the garage, however i can really decide to where i want the compressor :S

I wouldn't want to blast a shell with it...

Oh yes, the mess...
I did mine in a container. I blew it out with compressed air, and I swept it out, yet there's still soda dust everywhere!
Gonna get in there with the Dyson soon!
