York Air Compressor build

[TJVigilante]

Small hiccup: Do not drill and tap the discharge port of your York compressor for 1/2" npt. It does not have enough material...you'll just cut the inner portion of the port clean off (and burn your finger when you touch it right after drilling). Drilling and tapping the intake port for 1/2 is fine, but the discharge side should stick to 3/8". I'd do this for both the flange and rotolock/tube-o heads just to avoid paying $50 (shipped) for some Kilby fittings. Borrow or use existing drill bit and taps, $10 worth of fittings at Alaska Rubber and Rigging, and you're good to go.

Personally, since I already have the flange fittings and noone is looking to buy them, I'm in the market for a flange style head for this compressor so I can get it installed and on the road. This will let me return my drill bits, thread tap, and the new set of fittings I purchased for this project...a $65 return from an accidental screw-up. Whoda thunk it?
