Maybe it's not too far fetched, one of my close friends did industrial controls for years, and began by troubleshooting circuit boards for chromatographs. He got to the point of finding bad chips by feel, and actually measured the temp. difference. he could differentiate about 1 degree F by touch on a good day. He actually demonstrated this when I thought he was making it up. A frame tube wqarming might be tougher to feel due to paint etc but maybe not impossible. I won't describe how his dad troubleshot 480V electricla boxes- it still makes me nervous!

" I knew one guy who said he could tell a gauge by how fast it warmed up in his hand." He'd wrap his hand around the thin portion of one of the butted main tubes. Stevan Thomas Alameda, CA
