    Rebuilding Keyed Drill Chucks

    PS... forgot to mention that I have never needed to lock up the shaft using this method. If you strike the end of the Allen key sharply, the inertia of the armature, shaft, and chuck body is all the rotational resistance you need for this method to work.

    Yeah, that's what I have always done too, with reliably good success. The bigger the Allen key the better, as long as it will fit in the chuck, since you want maximum rigidity. Of course, we are talking about the traditional "L" shaped keys here. Chuck the short end into the chuck and whack the end of the long arm with a metal hammer, not a rubber mallet, since you want the shock of impact to break the thread grip. One strike is usually all it takes and if you leave the key in the chuck it is easier to spin the rest of the way off.

    The best part is the AWESOME floppy disks and drives. They look EXACTLY like the real thing.

    The Only knot you need to know.

    Great knot. I guess everyone has their favourite. The one I have used more often than any other in my nearly 58 years of life is the horse hitch. Supposedly used by cowboys to tie their horses to saloon rails, pulling on one (the horse) end just tightens the knots and won't give, while gently pulling the other end completely unties the knot. Cowboys could mount their horse with the long loose end in hand and release the knot "remotely".I have always used it for mooring small boats for the same reason. It is absolutely slip-proof when tugged from the "boat" end, but you can embark first and release the knot with the loose end once safely aboard. This knot often goes by other names, especially historically, such as the mooring knot (for obvious reasons), or the slipper...see more »Great knot. I guess everyone has their favourite.

  • Van Turned Dorm Room, Complete With Bed and Desk

    When I was a teen we called these "shaggin' wagons". In those days though the most popular conversion was a panel van.

  • Solar powered air conditioning unit.

    @drzcyy - Ummm... no. For any given cooling capacity traditional A/C technology is more efficient. While you do away with the compressor pump when using peltier coolers, you still need a very large fan on the hot side for house-sized cooling (bigger than for a comparable A/C unit), and the peltier slabs themselves are notoriously inefficient. Their greatest advantage in some applications is the ability to be be converted for heating just by reversing the current direction.For instance, those few-inch square peltier blocks you find in portable drink coolers are completely outclassed by the efficiency of compact drinking fountain refrigeration modules.
