sand blasting
Turbo Mini Forums

just got a new toy 10gallon sand blast tank, looking for advice on sand and grit to use, this is for chassis and floor work

grit from machine mart, or if you go with cash in hand to a local gritblaster, tey'll usually sell you a massive bag for not many pennys

best for body panels is broken walnut shells, hard to get but well worth it!

SKYLINES ARE LIKE CLITS, EVERY FLANGE SEEMS TO HAVE ONE: see this sticker on my silvia

the Search-section on this forum is blummin superb & simple to use, unlike some other forums, without the search-section & the help of this bunch of chaps on here i'll never be able to !!!Start the day with a 998cc turbo!!! :) i'm getting closer though!

Tom Fenton says: I have it all, make me an offer

I use the aluminium powder from Machine mart normally but have been known to pick up the odd bag from the powder coater when I've been in

I've just normal silver sand before now... but its not as good as the proper stuff and always needs cooking to dry it out!

been to blasting company today, there low in stock, told me a delivery due tomorrow £7 a bag to me dont no actual size let you no tommorow

yeah i go to my blaster to get it.

you cant use normal sand apparently as the way it breaks down isnt good for you or something? assuming silicosis or whatever its called.

getting a hug mofo of a sandblasting cabinet delivered tomorrow, and doing a bit of research as to what to use

from the various threads on here it seems actual sand (i.e playpen/silver) is a big no no due to health concerns

i know there are other options avilable, been offered a few buckets of powdered glass by a mate, but my old man thinks this isnt wise to use either?

is aluminium oxide the way forward then or what? not too fussed about cost as its got a big as hopper in the base to recycle the medium if need be

I am jealous of that cabinet!

As far as the media goes... walnut shell or glass bead are nice for panels or aluminum, if you have a big enough air compressor. Mine a 6hp 32gal compressor would not cut it. I wound up using black beauty which is basically slag to strip the body.

I have heard different things about soda blasting. One thing was that if you do not wash it all off throughly it could potentially form carbonic acid (or something) under the paint and bubble. Two, it basically polishes the metal so after you finish stripping the paint you will still have to hit the panel with 80 grit or so to get a profile on the metal surface fro the paint to adhere.

However, this is one of those long debated painted stripping methods... I am sure there are people that have used it successfully.

Looks simlar to my cabinate, we use to use quite corse grit and a larger nozzle but i have found fine grit with a small nozzle is the way to go, expecialy as you dont have a huge compressor.

ally oxide is the norm, but ive got some metalic looking stuff to try oneday too.

the main problem im having is the grit is so fine alot ends up in the extractor unit filter insted of the bottom of the cabinate!!

make sure y9ou dont breathe that shit!
use an old vacum connected to the extract hole.
ali oxide is indeed the norm, many different grades from fine 120 down to 20 which is like actual sand size.
What do you intend to grit ?

I wound up making a cyclone to try and separate the fine blasting dust before it gets to the hepa filter in the shop vac. It actually works pretty good... very little makes it past the cyclone.
