blasting pots

[optima21]

there is another version which is slightly taller, but the up plate is the other way round so works like a funnel to fill it

trouble is with the cheap pots they use a ball valve on the grit supply and block regular using inconsistent media . I did try one for a while and got fedup of it and made the tried and tested one I copied 40 years ago

I think you gave me the dimensions some years ago @brightspark, then I bought a commercial unit for a price I could not turn down, found it was not cost defective to do it ourselves so farmed out the work

so you have no gun just a length of pipe with the nozzle in it

yes just pressurise the pot when you start blasting and turn off when done nozzle just held in with jubilee clip on my small one proper holder on larger one but just the same set up

yes just pressurise the pot when you start blasting and turn off when done

one less thing to worry about!

How did u make tour pot dear sir

 

[brightspark]

there pretty simple. here's 1 of them. I make a quick release filler for them but u can use a cheap screw on one if u haven't a lathe to machine the boss and cap up

 

[123hotchef]

no no lathe! unfortunatly, so u just turn the air on and off to stop and start
