I was thinking about running a line from my air compressor to the area by my lathe. Do you still have to use galvanized pipe or can you use some type of PVC. My other thought as I really don't want to run galvanized pipe up the wall, over the ceiling and down the wall is to get an inexpensive compressor to set next to my lathe. Harbor Freight has a 3 Gallon 100 PSI pancake compressor on sale for 49.99. I would be using it to blow shavings from bowls, hollow form, my lathe, etc. I wouldn't be running any power tools with it. By the way are oil lubricated compressors quite a bit quieter than oilless.
