Finished the air compressor manifold bracked. It's much better now that the manifold is not floating around. Click the image for more images.

The pressure switch and manifold turned up from eBay =) It's now fitted and wired, set to go off at 100PSI.

A bit of hose and barbs from Bunnings plus the Gauge from eBay. The little compressor is now useable! It has a valve on the bottom of the 3 way manifold because I don't have a plug for it. On the right of the manifold is a Ryco quick release connector. The regulator is from some scrapped pneumatic equipment, an SMC AR30 which will allow 0-100PSI adjustment. The only problem is that the compressor doesn't have an automatic pressure shut-off.
