Does any one own one of these?

They have a lance (sometime just a hose you stick into a bucket of sand or other blast media) and and handpiece you hook air up to.

I was just wondering if they work ok...how much CFM do they need...I have 2 average home style compressors T pieced....should be 12 or 13 CFM.

I have been given a big-ish tent i can drive 1/2 a car into and was considering using it as a collapsable blasting room (or spray booth when i wash it out).

I'm embarking on a panel by panel restoration of my EH so I thought instead of getting the pros to do it all in one go...I'll just do it in manageable pieces..that way I get to keep it on the road...and things don't go rusty before I get around to them.

Nope. Those ones are no good.

Took me two hours to do an intake manifold, then i threw the sand blaster in the bin.

Keep looking mate.

You get what you pay for!
These little things work OK on little stuff! Need heaps of free air to work well. (30 plus) Small clean ups are OK, NOT panels! Great for pumping up the B/B or even tyres. Even blasted licence # into the glasses! We don't all have 3 phase and 60 amps.

So I might just be better of pulling the hand piece of of my blast cabinet.

How much CFM/ what type of compressor were you using?

Thanks for your replies...I almost stopped in on the way home to buy one. :clap:

They are Crap. Even if they do work its not long before the sand clogs in the gun or the hose. The Compressors are okay for small things..

I think I bought one like described from Toolex but one thing you need is alot of CFM.....my comp puts out 15cfm and was struggling to keep up with the flow but still do-able.

I wouldnt say there all out crap, with atleast 18-20cfm you could do the job. It wouldn't matter how much you spend on the sandblasting tool if the comp can't keep up you need to upgrade the comp.

I totally sandblasted my underfloor, engine bay and boot.

Sand clogging the gun and or hose(espicially the hose) sounds more like to much moisture in the sand :cry:

. Sand needs to be completely dry before use, any moisture is a problem. Also what abrasive material are you guys using. Normal sand becomes less abbrasive very quickly compared to proper sand blasting material such as aluminium oxide or soda etc. Not saying that the equipment isnt at fault (I have never used a supercheap blaster :gun:

), but there maybe other factors involved. Personally though I would spend them money on a good one at least it will last you a few years. :spoton:

I use garnet and ally oxide....both good...but garnet powders up eventually..I was told not to use sand as the silica in the sand stuffs the paint around..wont stick properly.

OK.

A few days ago i got to use a proper industral type setup.

Picture a 350cfm Detroit Diesel powered compressor blowing through 2 1/2" dia hose, positive pressure helmet and all that jaz, blows a ton of sand in 3 hours.

All i can say is I WANT ONE!!! Absolutely awesome bit of machinery. You seriously have to try it to understand it. Its a bloody adrenalin rush crawling over a drill rig holding onto the hose while the blasters going. Have been onto the boss ever since to buy me one.l

Completely useless info for this thread unless you feel like spending $50,000+ on setting up a sand blasting rig, but still through i'd increase the size of my e peen a bit

.

Cheers.

You can build an effective blaster using bits from supercheap etc, as long as the mineral sand grit is nicely warmed and dry it will suck up fine.. once your compressor starts to get humidified problems wil start.. you need a good sized tub with hopper and a perspex or better still glass lid, , mine was 240V floodlight and ran a cheap vacuum cleaner to purge the environment. sure as shit the vaccy died after sucking heaps of mineral sands but not after I had blasted at least 2500.00 worth of blasting hours.. I'll do it again for sure. more info.. PM me cheers.

I used to work for a sand blaster, we didn't touch cars we blasted and painted steel for large building contractors.

The biggest tip I can give any one is to sieve the sand thoroughly before attempting to use it. I tried to take the shortcut route a couple of times and blocked the nozzle every time lol. I quickly learned to sieve the sand well.

Now I have never used the Supercheap units and would suspect you get what you pay for.

If your nozzle is blocking up then you probably need to sieve the medium properly.

Hope this helps even if only a bit.

It may stuff with the paint i could not tell you for sure but what i can tell you is
It is ILLEGAL to use sand eg beach,brickie, ect in a sand blaster because
sand has silica in it and When the sand impacts it lets off a gas that causes silicosis and this will kill you. <(Definatly not something you want) PLEASE DONT USE SAND AS A BLAST MEDIA.
