Have you ever needed to know how many threads per inch there are on a #0 screw and how big of a drill bit you should use to create a hole in a sheet of aluminum into which to screw that screw? (the answers are 80 and 3/64, obviously). That sort of information comes from years of experience, or cumbersome reference sheets that you've spilled coffee on more than a few too many times. How about a digital form on your TouchPad? Yeah, we can do that, just look at Mechanical Reference Charts, which will tell you everything you need to know about screws, pipe fittings, sheet metal, drill bits, and everything else for use in the machine shop. This app is $1.99 in the App Catalog, but if you're game enough to leave a comment after the break, one of 50 copies could be yours for free.
Contest: We have 50 copies of Mechanical Reference Charts to give away. Just leave a comment on this post to enter. Contest ends next Sunday at midnight US Eastern Time, after which time we will select 50 random entrants to win. Please only leave one comment, multiple entries won’t count. Promo codes are only valid in countries serviced by the App Catalog, and users must be running webOS 3.0.0 or higher with the latest version of the App Catalog.
