Is it a hobby compressor or a bit more serious - sandblasting will give
it a good workout

Mine is based on a single drainer sink unit in a speaker cabinet

The blast gun came from machine mart, its worth going th extra mile and
getting a hardened nozzle

If you're interested I can give you a supplier for glass beads

I'd be interested in a glass bead supplier. Have been meaning to get
some, possibly from Machinemart, but if you know a better supplier that
would be useful info.

You must admit that in Which?'s favour. They _buy_ their toasters in
the shops, just as you or I would. So the one they test isn't a

Machinemart ?

don't be silly - a small tub for a lot of wanga

Hmm, 30gal tank, 2HP motor and rated at 135psi max - I'm not sure of cfm
figures yet. I'm guessing it's more 'small workshop' than 'hobby', but
I've no idea if that's enough grunt for blasting....

The blast gun came from machine mart

Urgh, those folks have been spamming me for several years, even though I
never bought anything from them (and efforts to tell them to stop worked
for a while and then they seemed to find me again) :-(

If you're interested I can give you a supplier for glass beads

Afraid I'm on the wrong side of the Pond these days Assuming the
compressor's up to the job though there are a few engineering places
in the nearby town, so I'll ask around and see if I can source from them
or find out who their suppliers are...

cheers

Just to give you guys the idea

my 14 cfm comp ..with 200 ltr reciever is just capable of blasting .

that's about 3-4 mins...90 psi......then youre down to 60 psi which
isnt good enough.......then wait a min for the comp to catch up...im
in no rush ..so it does me.

the machine mart nozzles for their gun do about 2-3 hours blasting
before they wear out..they cost about £6 each..

ive heard that you can use hydraulic coupling nipples as blast
nozzles ..

Thanks for that - nice to have some useful data. We'll see if the one I'm
picking up will cope with it - cfm figures seem to be typically around
6 for new 30gal compressors.

As with you I'm not bothered about a bit of waiting between uses, but time
will tell whether it works at all, I suppose. I'm only paying $75 (40
pounds or so) for it with hardly any hours on it, so I can't complain - I
just thought it might be fun if it might handle a bit of blasting too :-)

Hmm, interesting. I think I've got a few hydraulic odds and ends kicking
around in the junk pile...

As far as i was concerned Geoff, they were ..so called hardened ones
sold to me by machine mart ..and was talking about 2-3 hours use over
months .

which reminds now we are on the subject of cheapo chinese stuff.

.....if you have one of those Aldi 9 inch angle grinders .......put a
bit of grease on the face of the nut that holds the wheels on ......
i always tightened mine by hand, not using the spanner .......even
so ...the wheel yesterday ended up so tight ..........that when i
attempted to take it off .....the (very thin) alloy housing that
surrounds the locking plunger broke away.........making the plunger
mechanism inoperative forever ..unfixable.............meaning that i
had to strip the machine to get the debris out ..to do this, I had to
break the cutting disk off.........put the crown wheel in a three jaw
chuck and undo the nut with a large stiltsen...........at a later date
i will have to grind two flats on the spindle ...so i can get a
spanner on it .
..So grease that nut ...or modify it by undercutting it...if you don't
want a broken machine .......of course mine may have been a one
off ..but id like you chaps not to go down the same road ....seams
like a good machine ....otherwise ...needle rollers for the bearings
etc.

oh, and keep the guarantee and receipt handy ....doh..i had lost mine.

That happened to a cheap one I used to have back in England, too. It spent
a good two years with me jamming a piece of steel rod into the hole
in the carcass to wedge the spindle whenever I needed to change discs.

The current one I have over here is a bit better - it locks from
the side rather than the top, which should stress the components a lot
less (although in a piece of stellar design, the power switch and lock
switch look very similar :-)

So you have to appreciate that this is an abrasive process, and the
nozzles are consumables

That's your mistake. Tighten it properly with the provided spanner and it
will undo easily. Leave it loose - ie hand tight - and it will self
tighten and be difficult to undo.

I bought a Lidl 9" grinder for just the one job where I'd have had to
hire. Did the job perfectly and still works fine. For less than the cost
of a hire.

Hand tightening is gripping the edge of the disc and pulling up
tight .....who said anything about loose...............just not
overtightened ..that's the point i was trying to make .

done it like that for years with other grinders .......not had a disk
that was impossible to take off before in hundreds..just one of those
things that may happen to all of us.

so your angle grinder did one job perfectly ..........ok that's fine !

follow my points and it will do many more with a bit of luck,
just trying to help

OH...remember to keep hold of that guarantee ..it's a three year one.
