App Giveaway: 50 copies of Mechanical Reference Charts

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.

Count me in ;-)

Practical app!!

You might want to fix the first sentence. Whenever a screw size is declared, its diameter is always followed by its pitch. Also, given that there's fine and course pitches (though 0's are typically 80 tpi), a screw wouldn't have a single set pitch. So, you wouldn't need this spp to determine pitch as the screw size always lists it (unless your neighborhood hardware store isn't following standards in which case you better hope their screws are the common pitch). Also, I have no idea why the developer would charge $2 for this app when all those charts are free with a simple google search away (using just type, of course).

Sign me up!

I'm the family handyman & I can surely use this application.

Should I be at all concerned about the accuracy of a mechanical reference chart app put together by someone who can't spell Mechanical or Reference, and thinks "Charts" needs an apostrophe?

good idea
