[Shop-talk] compressor/sandblast guru question

[Doug Braun]

A permanent blast cabinet setup is so handy that it is worth putting up
with a somewhat undersized compressor.  You will have to stop and wait
occasionally, but that will take less time than:

1: earning the money to buy a bigger compressor
2: Actually buying it.
3: Getting it delivered and hooked up.

I have a 169.CFM, 6.5HP compressor, and it has no trouble at all running my
cabinet, with
a TP Tools medium-size nozzle.
