Sand Blasting Cabinet

[Steve MarshallParticipant @stevemarshall96556]

Purchased a sand blasting cabinet from JTF today. £48 instead of the £130 every one else charges. Great value for some other tools to. The website says only 5 left in stock but they had at least 20 in the Kidderminster store on Monday.

There seems to be a few deals on cabinets, I picked up an SB220 (aka Clarke SB30) for £135 delivered to my door, part one arrived yesterday, part 2 arrived today. Reasonable 1mm thickness. I've picked up a pair of round air filters for £4 each delivered and I'm going to create a negative pressure filter housing around the funnel to keep the workshop as free from grit/dust as possible (JCB/Caterpillar/CaseIH/Land Rover defender/Mitsubishi L200 common fitting filter).

I'm looking forward to getting it modified and running.

 

Edit* JTF also have this for £130 but its collection in store only (perhaps its pre assembled but at 48kg that would make it a bit of a handful!)

The large floor standing ones are excellent value and a very useful size, about the same as my Guyson, but you really do need an extractor & filter system. Unless you want to spend twice as long waiting for the dust to settle as you do blasting. Generally not a good idea to re-use blasting media from the filter unit collection tray. The percentage of fines will be on the high side and the extractor may not be able to cope so you still end up waiting. I imagine sieving is possible with fairly simple equipment but that sound very much a life is too short thing.

In practice the benchtop ones are a lot smaller than the disparity in size suggests. The amount of maneouvering room beyond the basic dimensions of anything being blasted is pretty much independent of cabinet size. So the real capacity is whats left after the manipulation allowance has been subtracted. Something around 6 to 9 inches each side and 6 inches or so in height is desirable. Which leaves very little easily accessible working space in the bench top ones. Given a bit of low cunning and a feel for the effects of twisting and turning to its quite possible to cope with rather less space but the job can become a right faff. Especially if you have to take what you are working on out, turn it and put it back again to do the next side. Tedious and messy.

Clive thanks for the tips, I'll keep that in mind. The cabinet as it comes has no form of filtration, it will just fill the workshop with fines. There is a large hole in the back, with an enclosed channel going down to the bottom, this is actually the air inlet, there is another smaller hole in the non door side for dust extraction. I think I'll be blocking this up and making use of the inlet as an outlet.

Sadly I can't simply connect up my 2000w shop vac as my compressor drops the voltage out in my garage a fair way, I don't think adding a kw or 2 will help much.

I'm going to enclose the base of the cabinet and fit an extractor fan (12v radiator fan actually) on the clean side of a filter plate which will hold the two Landy Defender/Mitsubish L300 2.5TD filters.

I'm hoping to open the dirty side up as much as possible to help any fines slow down enough to drop out before they even reach the filters.

Hopefully this will be enough, if not, I need a bigger power cable to my garage – and a bigger garage to put a dust extractor in!

I wonder also if some power factor correction could help (I don't know much about this except big motors and 200w worth of fluorescent tubes don't help, I should have paid more attention at uni!
