x2... I'm not a compressor mechanic, I agree with you though.

|Torque454||Yes, getting the correct size bushing was my recommendation also. That really is the best way to go.|

Unless you happen to have a large drill of the correct size and a 1/2 or 3/4 pipe tap laying around, it'd be a lot cheaper to go to a plumbing and piping supply house and buy a bushing of the dimensions you need. The current plug is probably either 1 1/2, 2, or 2 1/2" pipe on the OD. Bushings are widely available with any of those OD threads and most any ID pipe thread you could want.
Even if it has to be double bushed to get to the size you want, $10 or so should cover the bill. A decent quality 1/2" NPT tap and the corresponding drill is going to cost you at least 3X that much in import stuff, and $50 or more for domestic tooling.
One problem with attempting to drill and tap an existing fitting is that a lot of fittings on the market today are really poor quality from a metallurgical standpoint. Some of the worst are fittings used in high volume production products where cost rules over all else. You might be able to drill and tap the fitting you have, or you might rip the end off a $20 drill in finding out the fitting has hard spots in it.

|Sinister||The manual for my Campbell Hausfeld suggests either compressor oil or 10w30 synthetic. Running the synthetic because it's easier to get.|

What most guys will look at and call a 1/4" pipe thread is actually a 1/8 NPT. Same thing all the way up- the NPT size is numerically smaller than the size of the tap would lead you to believe.
That said, if you need to go larger than 3/8 NPT, the next up is 1/2 NPT. It's big. 3/4 NPT is BIG!
What I believe smithkustoms is suggesting, is to drill out and tap for a larger diameter outlet. The hole would be drilled w/the proper bit for the NPT tap to be used to cut the threads, then the larger diameter pipe fitting would be screwed into the new hole. There should be zero reason to "have the tap fly across the room when you first use it".
Maybe you're confusing "tap" for a type of fitting, as opposed to the tool that cuts threads?

|stimpy||the compressors we used on the boats used non detergent 30 wt , the detergent causes the rings and valves to coke up and the comprressor doesn't get hot enough to boil off the water vapor and when that combines with some of the detergents it makes a acid in the crankcase .|

|matt167||I gotta pump the oil out of my push mower.. it uses a second deck underneath, which covers up the accessibility to the drain plug on the engine.|

Some people slay me w/their "set it and forget it" mentality.
Last Tuesday, I had brought out my lawn equipment to ready it for the upcoming season. I had neglected to change the oil in my push mower last fall- it hadn't been used but maybe three times, so I lazily had put it away as-was.
I had a pan of old oil sitting nearby and was refilling it when Don from next door idled up, beer in hand.
Nodded a greeting and continued my work. After about 5 minutes, he goes, "Watcha doin', Mark?"
I looked at him kinda funny, ans told him I was just sharpening some blades and changing the oil in the push mower.
Incredibly, he said- w/straight face, "You can do that?"
I like to have fell out. lol

that said, I do use compressor oil in mine, but it's what came with the compressor when I bought it.. havn't gotten to a change interval yet

|Raufus||Mine doesn't look like motor oil at all. It's almost clear. Why take chances?|
