    Lightbulb Precise Angle Control While Drilling

    Hi all,

    As I fasten the floors into Astraea's keel, I need needed to drill holes at a precise angle using a handheld drill. The short videos below show the solution I've come up with, which works well, and I'm pretty proud of. Posting here in case it might be useful to anyone else. The app I'm using is called "Clinometer".

    That is pretty clever.

    That is both cool and useful.

    I am not very good at writing apps for android (yet), but it just needs a little bit of damping or displaying just an average.
    Sound like a great project to improve ones programming skills. Will only take me a couple of years but it sounds fun.

    Great idea. And the boat’s looking great, too.

    I have one of these critters. Seems to work reasonably well.

    Hope for the best, but plan for the worst.

    What's that long rubber covered snaky thing with the metal on the end that's stuck into the end of the handle?

    Idiot string so that you don't lose the chuck key...

    Makes sense - especially if it's in love?

    I gotta say I kinda like the phone attached to the drill though... Ingenious!

    Used my iphone's inclinometer to set my bandsaw bed to 9 degrees yesterday (breast hook midline cut bevel before rounding/ backing out). Its certainly accurate, though to be fair, the bandsaw's dial did also read 9 degrees. So I know that's right too and doesn't need (re) adjusting.

    Its on the compass page thing.

    There are two kinds of boaters: those who have run aground, and those who lie about it.
