Does sea sand work in a blast cabinet?

Hello

My new sandblast cabinet has arrived but the black grit I bought at the
Stafford Show is too aggressive for aluminium. A friend suggested very dry
sea sand instead.

Any thoughts?

John

 

Buy a bag of kiln-dried sand from a builder's merchants, I would.

 

I could well be wrong here, but I'm sure I read in one of the
classic^^^ SOC rags that blasting with baking powder is good for more
delicate items - can't check as the mags been been lobbed

 

Try bicarb of soda

Yeah, nuts. Well the shells of nuts actually. Ground up (and available for
blasting use) and far less aggressive than sand or most other blasting
medium.

Can't Nige be stood close to the object. He's fairly good at "blasting".
Come to think of it he may have to tone it down a bit or it'd be too
abrasive.

For me it'll have to get past the Mesothelioma first.

I was in several garages in the early eighties, where they blew out
the brake drums with an airline ..

Well he's nutty enough, but grinding him down would likely prove to be a
long process.

Using the patented Mavis Beacon "Hunt&Peck" Technique, eatmorepies

I have read that ground walnut shells are the "soft" medium of choice.

 

Don't they do that now? Fucking wimps.

Are you willing to pay for the right stuff ?

Glass beads is what IWHT you want

I use 150-250 grade glass beads for cleaning up aluminium

The company I used to use has gone out of business, I'll have to look up
the new company I use tomorrow, but I buy 60kg at a time - its going to
cost more than a tenner

 

Cunting Insurgent Asians?
Cunts in (the) Act?
or something.

 

I know ....

<wheeze>

Paul.

 

I've ordered 25kg of those very glass beads - my aluminium will look
splendid.

John

 

<cough> What?

He's hardly mining for gold.

 

When I was a callow youth I needed to fit some new brake shoes to a SO
Suzuki 50. I know reailise that the drum was so badly worn that there
was a lip on it. What did I do to get thet tne shoes in ? You guessed
it - ground the shoes (asbestos containing) down with a grind stone
(no angle grinder for me in those days).

Mind you, when I was a white hat I remember going upon the roof of a
power station that was about to be demolished. Most of the asbestos
lagging on the external flues had long since gone with the wind.

 

In the late 60's I worked for a time in a warehouse that stocked all sorts
of sheeting material. Plywood's, blackboards, etc and Cape asbestos, both
soft (crumbly) and hard (roofing).

Everyone who smoked there sat on the asbestos sheets because they were less
likely to burst into flames than the creosote treated wood panels or ply
sheets. They were always handballed onto the lorries and off the lorries
when they were delivered or when customers came in for single sheet orders
and there was always clouds of dust when they were moved.

I don't recall anyone ever thinking "This might not be a good thing" though.

The other blokes that worked there are all probably dead now.
