Cheap sandblasters on fleabay?
There are a number of cheap sandblasters on ebay, under $200, has anyone had any experience with these things? I'm not wanting or needing to do hundreds of parts, probably only use it half a dozen time but it will pay for itself easy at those prices.
Are they any good, or useless rubbish? Ben |
I don't know about the ones on fleabay, but I bought one of the harbor fright ones second hand from someone that had added caster wheels to the legs. It's OK, the panels leak like crazy. I need to take it down and use RTV at all the joints. The gloves are very thin, and if you hold any parts to blast them well, the gloves will wear quickly. The tear away sheets are useless. I just go to my local hardware store every once in a while and buy a couple new pieces of lens glass. OK for the usage, but if you can get better, I say go for it!

Blasters
Mando,
I purchased one from Hare & Forbes ( $370 and $450 for the vacuum assembly ) I was told to use Glass beads for auto work. It wa sthe wrong call, I changed to Garnet and things take 1/4 of the time. I am still contemplating getting a bigger one as you use it ALL the time, it such fun........... just need a good capacity compressor to keep up. STIFFY |
Not sure which type you mean, but i have used the really cheap hand held one that you put a tube in a bucket and also the ones that have a tank for the abrasive.
As Stiffy said Garnet is you friend. I bought a bag ages ago and have reused it about 20 times. I used the hand held gun with the bucket to do fairly large parts just by folding up a sheet of clear plasting and taping around the edges with duct tape. You can then just use it as a giant cabinet. I just wear welding gloves and a welding mask with a clear lens. Definately worth getting if you are prepping parts. I have done all my suspension parts like this including the entire jag front subframe. Just prime and paint after or POR 15. |
I have one of these guys, I am yet to use it (as I want to put it in a different spot) no garnet added yet to save the weight.

This is what I did about 10 years ago.....
Build-Your-Own Cabinet - Trigger-Operated System - TP Tools & Equipment Bought the basic $99.00 kit, back then,probably about 50 bucks......One and a half sheets of plywood,built my own cabinet,it's 4 feet wide X 2 feet deep X about 30 inches tall..took me an afternoon to build it with help from a buddy....I probably spent no more than 100 bucks all total, but I did have the blower and some other items around the shop before hand......I made the front section where the lense is,hinged,so I load from the front, I use plexiglass for the lense,works fine.....I have two regular 60 watt light bulbs inside and a small squirrel cage blower mount on the outside to draw the air/dust out,all wired in to one 120volt switch........works like a charm,very inexpensive..... Also,depending on what your blasting, I use regular sandblasting sand, I find beads do not cut enough when things are rusty and way too slow... I used their basic plans, just made the cabinet larger for my use....Once you have one, you'll wish it was bigger, and you'll use it all the time....I'd bet I use mine on average once a week, it's just too easy to go in the shop, turn on the air compressor, flip a switch and be blasting/cleaning up anything in less than 5 minutes......

I have the cabinet blaster as well as the type where you put the tube in a bag of abrasive. Obviously you can't put a large piece in the cabinet whereas you can blast anything with the remote gun. Both work pretty well if you have a large enough compressor

I just checked and the filter is 14 inches square with an 8 inch hole in the middle.........
Going to try to attach pictures of the home made cabinet and filter..... David http://www.clubcobra.com/photopost/d...01_640x480.JPG http://www.clubcobra.com/photopost/d...05_640x480.JPG http://www.clubcobra.com/photopost/d...04_640x480.JPG http://www.clubcobra.com/photopost/d...03_640x480.JPG |
I have one of the named blast cabinets too, I found that the garnet was a pain as the gun was clogging all the time.
Hoe ever the glass beads are great, I have used it for lots of small alloy and steel parts but no greasy suspension bits. |

David, With the sand, i have used it like that too. Problem is moisture but putting an oxy on it and shoveling around in a wheel barrow dries it out. Doesnt make it safe though. Wear a mask. |

For smaller,"delicate" items, I use the beads..... David |
I bought one from Radum for about $250 and it's been good. They have a showroom where you can check them out and are not a dodgy eBay seller and you will get some backup on your purchase.
Radum Pty Ltd I welded up a frame for the legs on mine to lift it up a bit. It's made for someone shorter than me. I also added some castors to make it easy to move around. Probably cost me another $100 in materials. Cheers |
I went with TP tools to keep it american mde. You ca go to habor frieght for half the price, made in china. Be sure to use a water trap on your air line so that you do not clog your media as stated in other posts. I also use mu shop vac to clear the air inside the cabinet. A provition is on the side of the blast cabinet for it, you just need to attach the hose from the vac and duct tape it or purchase an adapter. They do use a high volume of air so make sure your compressor is lage enough. At least a sixty gallon compressor, anything smaller and it will run constantly and may not provide a steady pressure.

As Gav mentioned the biggest issue with the cabinets using Garnet is moisture build up. The Garnet dust turns into mud inside the nozzle and blocks it up. You have unscrew it every now and again to clean it out. Garnet strips much better but glass beads flow better. I'm looking at building a water trap setup on the inlet to the air to try and keep the moisture out. Cheers |
The best cabinet ia made by zero blast. They come with a turbine that sifts the dust from the good beads. They are quite fast don't leak. There is really no comparison. ZLook and wait until one come for sale. You won't regret it.
ZERO BLAST - BLAST CABINET & DUST COLLECTOR / SINGLE PAHSE | eBay The above unit is a little smaller than mine. I waited and founr mine for $500 at an auction. It is so quite you can talk while blasyting. You can blast for hours. They do need a real compressor. Mine is a saylor beal 10hp with a 120 gallon tank chris |
