I know the subject has been pretty much beat to death over the years, but in my searches/reading, I couldn't find much about smaller garages.
I have a small two car detached. It's about 17 x 17. The left half is my work space and the right half, I try to keep clear enough to pull a car in. It has a flat roof sloping towards the back and two garage doors with no man doors.
Planning on locating my compressor in the back corner of the work space area. I just have a single stage 110v model. I don't have 220 in the garage, and being that it's an old house, it isn't even an option without upgrading the whole house (believe it or not, I have 40 amp service to the entire house).
The compressor will supposedly put out 125 psi max.
Basically, I'd like to run a few short air lines to service a couple of work tables along the wall on one side, my main bench along the back wall, and run a line up the main beam to the front of the garage so I could run a spool close to the garage doors to make airing up the vehicles easy.
With a garage as small as mine, I could just live with a hose directly off the compressor, but the annoyance of knocking things over, getting it caught on whatever's being worked on, etc. - it would be a bit easier to have some hard lines on the wall and short hoses that don't get tangled up everywhere.
Mostly I'll be using the compressor for airing tires, blowing crud out of things, and perhaps an occassional air tool. I have a plastic welder that uses air, and I'd probably use it more often if I didn't have to haul out a hose and everything to set it up. Possible I might use a touch up gun to spray paint something small, but I can't paint something like a car in my neighborhood, so there's no point in setting myself up for that.
So I'm looking at around 50' of hard line.
If you were standing at one of the two garage doors looking in, I anticipate the line run would start at your left at the left garage door, sloping down slightly to the corner where the compressor is. Then it would continue across the back wall to the right, still sloping down until it reached the middle of the garage. Here there would be a drip leg with a drain valve and the line would go up to the ceiling, then run along the main beam up to the front of the garage where there'd be a fitting for my spool.
I figured I'd use Ts pointing up at several points along the left and back wall where I could attach air couplers. This would also allow me to move the compressor elsewhere in that half of the garage if the need arose. I'd also put a capped T on the run going up the back wall in case I'd ever want to extend the line round the right side of the garage.
All in all, I'm probably looking a 16' run with maybe 4 ports along the left wall, an 8' run along the back with 3 or 4 ports. Perhaps 4-5' up to the main beam, and another 16' to reach the front of the garage where I'd have the hose reel mounted hanging down on a 2x4 bracket off the main beam (I have to get it low enough that it's below the garage door tracks).
Figured 1/2 copper would be appopriate for a small setup like this. I'd run it on the face of the wall about 6-12" above workbench height.
Looking for criticism/comment/advice. Am I on the right track here? Would 3/4 copper be better, or is it not worth the extra cost in a small setup like mine?
I replumbed my house in copper (years ago when copper wasn't priced like a precious metal), so I can solder pretty competently.
