Portable Sand Blaster - Any Good?

[Chris Abraham]

I use a large Wolf Dakota 90 litre 14cfm compressor. I built my own pressure pot from a large Co2 fire extinguisher. Runs like a dream, pressure pots are so efficient. The biggest draw back is not overheating your compressor. With the Dakota you can use it continuously for 12 tank charges but i found that if you get a blower directed on the cylinder of the compressor then you can run it as long as you want without damaging it, as the blower cools it right down. Another trick is to make a pipe system about 6 or 8 upward runs about 2 metres each section that act as a moisture trap which can be drained off after use. You will be surprised how much trouble moisture in a blasting system can cause, a must to build and use.
