Charlie,

Come to Michigan. We not only get lake effect from SW all the way around to SE. but the acid rain from the industry all the way around the South end of Lake Michigan. I couldn't open or close the N man door on the garage fot abour 4 months due to ths concrete apron and floor heaving.

The S man door on the shop is about an inch and a half above the apron. By the ebd of December I could only open it 90 degrees before the corner of the door fit the concrete, At he end it reached the point that I could just squeeze in sideways between the door and frame.


Our roads are covered with a mix of sand and salt, but most of the time the salt freezes too,so they go to Calcium chloride which I think is good for another 10 degrees. So it slings the salt filled slush up to thoroughly coat the bottom and keep the salt there till spring. You can wash it off, but it's usually coated thoroughly by the time you get home.

Chicago's acid rain (clear up here) makes a set of Aluminum screens good for a season or two. With the sun and chemicals, nylon screens last about the same.

You really need a winter and a Summer car up here!

Dow "used to be" a problem. In 61 with the wind out of the SE I could take off from the local airport and follow the cloud all the way to Traverse City where it was still only a couple miles wide.

Now you neither see it or smell it. They have really made some strides in the environment. They blame Dow, but the are the ones who developed the ability to measure such small amounts to clean it up. No, I never worked for them.



I understand & I'm really only interested in the shear strength of the bolt itself. When I was in 1 land I wasn't as critical about hardware as I've learned to be here in 4 land (Southwest Coastal Florida). I learned rather quickly that the rain down here is just about like battery acid!!!! When I first moved here a year ago I was unable to keep my 1940 Ford Hot Rod inside for about 6 months & you would have thought it was stored in a salt bin by the time I made room in the garage for it!!! Between the rain rusting everything in sight and the sun trying to kill my $10K paint job, it was a painful learning curve.

When I was in Ct. these problems never plagued me, but down here it seems to be another story.

Everybody has problems.  Conn is the government and taxes.

See my other reply. Say you are using a grade dh carbon steel nut, they are up at 175k, a standard grade 8 nut is 150k. That is above the A286. Like I said, just be careful
