Thanks for the post. It is a useful reinforcement of the information you emailed me a couple weeks ago on 52100.
I would like to disagree with your suggestion of requiring two pages of reply to include in the index sticky. The day before yesterday, I referred again to a post of yours elsewhere on the three steel types. My head hurt the first time I read it. (Most likely the rum more than the content

) I didn't reply back then - or even this time, but that doesn't decrease the enduring value of the information.
Keep writing my friend, and please index it all in a sticky. If I don't respond, it's just because I'm socially inept - not because I don't value the gift.
Rob!
