I'm terribly sorry, I won't mention it ever again! :-(

None that I know of besides avoidance.

Why? Freeze some bits? Or just feeling a chill around here? :-)

If you froze any of your body parts, see a doctor. And be prepared to
suffer the cold forever after, as frostbit parts will be suceptible to
cold, pretty much forever after.

Infections and gangrene are real risks.

'Cause of the Palm trees, of course!


The lake here is deep. Plus side of 300 feet. It does not warm up much
in the summer.

Lake trout fishing is pretty good right now. I was out on the lake on
Saturday, and it was a beauty day, sunshine, almost no wind, and
hovering just below zero. Only caught 1 fish, not a keeper.

This kind of weather costs me too much. Staying indoors, leads me to
ebay. :-)

Yes, I think it should be UNS at 16TPI, at least that is what the
LR4X4 forum thinks it is. I suspect the chart I quoted was actually a
missprint and called it UNF instead of UNS. It is also a fairly common
size used on some plumbing fittings so I suppose it could be called
"special". As UNS it is listed fairly often with the tapping drill at
5/8", as of course is 11/16UNEF at 24TPI with a tapping drill of
16.6mm.
