I pulled the compressor out from under it's roof today and it took me a while to find the hole it was so tiny. I tried to open it up wth a dental pick, no dice, so I fiigured it must be pretty solid around the hole. {it was a really tiny hole!] I took a 1/16" drill bit and drilled it out. The metal looked at least 1/16" or better thick, so I set up my mig welder and did a practice hole on some metal I have that looked about right and when I was sure I was getting solid penetration. I welded the hole in the compressor tank. Zap, it was done, looks good. Changed the oil, long over due! Reinstalled it and fired it up. No leaks and works perfect! For how long, who knows, but it is good for now! -- Mark Price markprice242ATadelphia.net Morgantown, WV
