useful charts or calculators for working metals and other materials

[Frank S]

I used to have a very large folder called table of specs with over 100 sub folders and 1000's of files in each of them. Now not so much but I decided that some of the ones I still have might be useful to others at least they will be all in one place
Feel free to add your own files to this thread maybe we can populate it is with some of the harder to find data or at the very least we can find it here

In Digging through many other files I find that I do have 1000's of files many of which are engineering files but some even zipped are over a gig in size but some of those I had to purchase a license to own them so those naturally can not be up loaded either in whole or in part.

May I suggest;
Jon, initiate a distinct category in the HMT forum of tables [or links to] such as Frank S, Doug Ross, Marv Klotz, Rick Sparber, PJs and others compiled. I'm not playing favorites, they're in no particular order.
Marv's though are of his own composition, so we can alleviate tedious calculations.

TM51 part of the reason for starting this thread was in hopes that others will post their charts calculators and calculations in this thread that way some day we might have a single go to for finding those troublesome pesky bits of hard to find data.

Thank you, thank you, thank you Frank S!!!!

As I discover more of the charts locked away in my drives if they are relevant to the many things we do here on HMT and I can either reduce or extract them from the host files I will post them

In full agreement such a thread is more than beneficial on the surface; I'm soliciting Jon to put it on the header like Tool Plans, Awards, Builders etc. Newer members [even as a way to attract them] and present crew could direct searches far more specifically.
