I was tired of the tangled mess of the air hose, especially when working in a cluttered or confined area. So I waited till a retractable air hose came on sale and mounted it on the handle of my portable compressor.
A scrap piece of ¾ in plywood (7x10 in was the size that worked for my compressor)
A roll of steel suspension strapping
8 - ¾ in wood screws
3 - 1½ long ¼ in bolts
3 - ¼ in lock nuts
3 - ¼ in flange washers
