Hope this isn't classed as a hijack it is about air compressors lol.

Read what John was saying about compressor outputs & that he had said to look out for hydrovane series 5 units but I'm not sure if something that size would do for the blast cabinet, the 5 series from what I can see chucks out about 5 cfm & the blast cabinet needs a minimum of 7 cfm @ 80 psi, more would be better.
Realise from Johns post that those figures might not mean a lot so needing a bit of help with what might be suitable without having to take out a loan.
