Stumbled onto this website:

http://www.engineersedge.com/

The site has a variety of different calaulators usefull
to those of us who like to make chips and do metal
fabrication. Best of all its free.


You ight wish to do some checking if you need this for critical
applications. The input fields don't seem to do any "make sense" bounds
checking - for example the Fastener Torque calculator cheerfully accepts a
fastener diameter of -1 inch.
