Bought this sand blaster about two year ago. Made up a new lance for it today which works sweet.
I've completely stripped one Capri with it so far and so much other stuff it's not funny. Never a warped panel and sand to clean out but when attacking rust nothing beats them or comes close.
My first Reno Capri as soon as I got into the A pillar was fully blasted and no rust was left before rewelding panels into place. I swear by this nowadays and won't attempt sanding or grinding again. It's petite when you need it to be aggressive when you want as well as recyclable and cheap.
My sand blaster was $137 off eBay but I put a much bigger shut of down at the base to reduce constricted flow there as well as larger piping. I use bunnings dried sand as the medium and after years of removing rust on things it is by far the best way in my opinion. I have a newer soda as well sand blaster I've never tried as the original
Works so well. A couple of pics with my new lance. It's just copper pipe with the Ceramic fitting in the end.

Got some pics of your setup mate?
I was looking at the cheap eBay ones and wondering about them a little while ago.

I've got and tried to post the pics but as you will all know sometimes they go 100% then sometimes they stall. Or is that just cause I'm on the Nbn. Here I will try again

Managed the Pics on the laptop. Here they are great little invention.

And a Guard I sand blasted myself. Around 2.5 hrs work and $7.00 sand.

thanks for posting Wiggy, I've thought about one also.
$140 is worthwhile.
How big is you air compressor, do you need a large one to run it?
I have just a basic 1.5hp I think, not belt driven which was given to me.
It runs a small spraygun ok but I don't know if it would be suitable.
 

No you need a decent one if you want to do lots. I've got small compressors at 2.5 hp but I use builders ones for big areas like 12cfm to 17cfm and they can run constantly and have 15amp plugs. When I did the whole car I used two of them so it wouldn't over heat and ruin them but it kept the blaster going. Depends on your speed and expectation you could do a diff or strut in 10 minutes with a small compressor still beating any other way.

Im seeing it as this one off eBay is the one you have yeh?

Yeah that's it. I added a hose tap at the top to vary pressure at the top of the tank and a larger hose tap (ball valve) at the bottom. This means if I get a blockage caused by built up moisture I can vary my pressures to clean it out.

G`day Wiggy
I`ve got the same blaster but havent got to the stage where i need it yet, how much sand does it use? eg how long does a 20kg bag of sand last? Whats the go with the lance? Does it make much difference or does it just keep you further from the blasting?
Cheers mate
