I'm working through a plan to sort out an air supply for respraying my MG; looking to run a standard spray gun and an air fed mask.
I have the following compressors:
3hp with a 150 litre tank; outlet is via a 1/2" hole on a tank plug
2hp with 50 litre tank; outlet is via the 1/4" hole that lead to the factory regulator etc (by-pass to be fitted).
I intend to link these both together and run the combined output via one or two copper pipe drop legs in the workshop. These will lead to a 1/2" initial filter / regulator and a further filter unit to give sprayable / breathable air.
I plan to use 15mm copper pipe to go with the 1/2 fittings and main tank outlet.
I have a couple of specific questions:
1. I initially thought I would replace one of the tank plugs on the 2hp compressor and use a 1 1/2" to 1/2" reducer. The thing is I can't get the tank plugs out. One has rounded off and I have tried everything I can think of short of drills / saws etc. The other end has slipped once and I don't want to go any further with that one. Does the likely increase in flow that could result from using a 1/2" outlet direct from the receiver, instead of the factory 1/4" outlet tube, make it worth the hassle of drilling / cutting out the mangled plug?
2. For the 15mm copper, will standard water piping do the job or there some specific stuff rated for air?
3. After the filter stages I have to run the air across the back of the house to the garage - about 10m. I can't use fixed pipes, but will have to go with flexible tube and quick release fittings. What would be the best size and material to use for the tube? Which type of quick release will give the least restriction to the flow?
4. I was thinking about another regulator, or at least a pressure gauge, in the garage so that can correct for any pressure drop in the system and perhaps allow fine control of gun pressure without having to leave the garage. Would this work / be worth it?
All thoughts gratefully received.
Thanks.
