air tools and (sorry) compressors

[Richard K]

I realise this has been dealt with to a degree, but the board is quiet and I'm going blind sifting through all the compressor posts.

As my Viair has packed up I'm looking for a replacement set up - for tyre duty and also to run some air tools.

The ideal looks to be an A/C compressor on the engine, but the time it would take to A) find the thing. B) fabricate a bracket C) figure out why it still isn't working D) go back to the scrapyard etc. etc.....would probably be better spent making the brakes work properly.

So, to keep things quick and simple:

Would a standard £100 Viair charging a small tank be enough to power tools? What other bits and bobs would I need (regulator etc.) ?
What would be the minimum size tank ? and minimum power compressor ? and would it fit under the seat of my 110?

Or should I just bite the bullet, roll up sleeves and start digging around in old Mercs at the scrappie?
