Sandblasting advice

[bourbon]

If you have been able to buy both within your budget, no way are they legit. The Clarke one on it's own is over a grand new, and they don't loose their value that much

 

[marsden]

I cant be bothered to look up the stats on them, but its looking much more hopeful!

They are both 14cfm

if there both 14cfm they will run a 3.0mm blast jet nicely an airfed mask will pull a fair bit of air and reduce it you could use a decent face mask with cheapo face shield to get you away without getting peppered i got a fair few given if you want some

Please yes that would be very much appreciated

You've surely been done... Those two compressors are supposed to be nearly £2.4k. You did not get them in working condition for £500.

Is 3mm the max? On the pot it states 125psi is the max and if it's over to use a regulator what type do I need as I have no clue

They both run sweet

 

[marsden]

That was one and I paid 300 don't have a screenshot of the other as it's been deleted

25cfm will keep up with a 3.0mm jet at 90 psi, i dont bother using a regulator i just run mine at full tank pressure cant even remember what mines set at i dont bother looking just take of the end of the tank

 

[Jackimus]

Well, I've got no clue how you managed that, or if they're legit, but hats off to you if so...!

Sometimes machines come up cheap.

A couple of weeks ago, i bought a machine that currently retails for between £2300 to £2800 for about 10% of its new price.

These things just happen occasionally.

Is it safe to use without a regulator

Will both compressors be able to keep up with our stop and starting

 

[brightspark]

they should be able to hold a minimum constant pressure round about 90 psi which is about optimum pressure for blasting

What's the best stuff to use for blasting I've been told to stay away from sand what's everyones opinion

expendable scangrit superfine copper slag crushed glass and some do use sand

[brightspark]

Which is safest to use

the 1st 2any dust is dangerous to health without a decent mask or used in a cabinet with good extracta or airfed helmet for open blasting
