hi i was wondering if anyone could possibly help me.ive bought a 2nd hand 10 gallon blasting pot and i seem to be having a few problems.i previously had a blasting cabinet which was too small for the wheels that have been blasting.my pot came without any instructions and am at a loss as to what is wrong.i have given everything a thorough clean and yet the flow from the nozzle is very intermittant and no matter what i seem to do it remains the same and even sometimes doesnt work at all?any help or advice would be gratfully accepted or if anyone can tell me where i may be able to get instructions for such a pot would be even better.many thanks to the couple of people who replied to post under the name spangled123 .
