billyO Posted July 3, 2019 Share Posted July 3, 2019 Mr Harris, were you able to get an ID? Link to comment Share on other sites More sharing options...
Donal Harris Posted July 3, 2019 Author Share Posted July 3, 2019 No. I pretty much abandoned it after I realized getting precise volume measurements would be a problem. Now it occurs to me I wouldn’t need to measure water displacement, but could just cut off a specific length and do the math, but I would have the same problem. I wouldn’t be able to take precise measurements for anything except weight. But I think if I could do that plus be able to accurately measure certain other physical characteristics I could identify the steel. The problem is I can’t accurately measure any of those either. I still plan to visit the engineering labs at OU. I bet I could find a student who could help me out for a small donation to their beer and pizza fund.

Donal Harris Posted July 4, 2019 Author Share Posted July 4, 2019 Nothing important. I just have a thing for carrying small items in my pocket. It gives me something to fiddle with during meetings, but they tend to get lost. When my wife buys me new “lovey” as she calls them, she always buys a couple of spares. A piece of round bar that I picked up turned out to be perfect after hardening. The weight and texture was amazing. I only have about three feet of it, not counting the three feet or so I gave to Chris. It is silly but I thought I might want to determine what the steel is, just in case.

But I bet you're right regarding the OU engineering student! Link to comment Share on other sites More sharing options...
