I just completed my sandblaster project - look here:
Remember the translation to the right - just under the menu line !

The little spherical tank was originally a sand blaster in it's own right. A gun using a compressed air line sucked the sand up by venturi action, and the used sand was sucked back into the pot by an attached vacuum cleaner down the outer of a co-axial tube, the centre of which was the 'sucked up sand' line. The blasting nozzle was surrounded by one of several shaped rubber cups that restrained the used sand. If you look at the 'skirt' of your tank, those holes were where different shaped rubber cups were stored. They were intended for small scale car rust removal - just small spots of rust - the shaped rubber cups were made to fit round things like door edges, and also there were flat ones for spots in the middle of a panel. Tediously slow to operate if doing more than the odd square inch.
I sold mine about 8 years ago
What grit are you using?
-
I don't know what sand is used ! :loco:
I just used the sand in the "tank" and MAYBE it's like the sand in the new bags - I don't know :Doh:
The way I'm going to use it - cleaning small parts - it will Work fine :drool:

Good job! I've found my sandblaster invaluable. I normally use Aluminium oxide grit in mine but may switch to glass beads when I refill it. One thing I found is that it can be run on a very modest compressor, mines only a 25L 2.5hp unit and it works fine.

Need to keep the pressure up to 90 psi or more - so if your compressor struggles use a smaller nozzle. Grit impact speed is the key, not grit volume.
Don't use sand unless you want to develop silicosis.

Vacuum extraction is recommended as well.

I think I say wrong ... what I mean is 8 BARS !
We have had this discusion before: http://madmodder.net/index.php/topic,8079.msg86466.html#msg86466 (http://madmodder.net/index.php/topic,8079.msg86466.html#msg86466)
But I'll still use the unit as shown here :loco:

Quite correct using sand you may develop silicosis and why its banned in industrial applications.
Works great once dried and cheap £2 a bag. It should perform totally different to the video. Give you some idea it must have took two minutes to do a spec of paint that with same gun can do in 5 seconds by altering the pickup.
Problem with those setups is the gun and pickup. Changed over to the BHP12 and pickup last year, now fire aluminium oxide 60/120grit at high speed a mass volume. 5 secs to do the bare metal area on back of cabinet.
I still get the constant blockages with the pickup so I now run as little grit in the cabinet as possible about 5 to 10secs worth of blasting before having to move media over pickup recirculation hole in bottom - modded.
Really need a bigger cabinet this year.

Wow - This is really beautiful. Thanks for sharing What will be your next project?

Very nice job.

Oh, I have way too many projects in the pipe ... I can just pick one ! :palm:
As I say: If you run out of project ideas ... then you must be dead ! :med:

Very nice job.

Thx Mike
-
Very nice.
Does anyone know if, instead of Aluminium Oxide you could use this for soda blasting? Interested as it's better for cleaning aluminium or more delicate parts

Ksor,
A blast from the past - I've been clearing some shelves, and discovered that I DIDN'T sell the little spherical spot blaster that we discussed back in July 2014 - it is the same as the tank you used in your blaster - so I thought that you'd be interested to see how it was originally.
There are various differently shaped nozzles that mask the area to be blasted, and the grit in vacuumed back into the tank
It's in a bit of a mess having sat in a box for 8 years unloved !!!
(Having a New Year clear out :clap: )

Hi Andrew
Yeah, that's the one ... argh, a little different - the pistol lokke very different and I DON'T have all these different nozzles.
I found out mine is very critical with the moisture in the sand.
I too found out that some parts combining the insode hoses and the hose to my cabine is nearly "blown" away - i have to make some new or buy them - but where ?
-
I understand that it was originally sold for touching up car bodywork. Just blasting away the odd rust spot without creating a big mess. I'll probably fettle it a bit and get it working again, as it's a useful addition to the weapons :clap:
Funny - I was convinced I'd let it go when I moved house, but found it when I needed more shelf space :ddb:
