  • How to Sharpen Used and Dull Drill Bits (By Hand!!)

    I've read the whole thing and most of the comments, it seems most of everyone has a similar opinion, similar method and most have done it before. Now, for those of us that haven't and have no idea. Could you please explain some terminology as in "landing"? "lip"? "Chisel angle"? I think I've got chisel angle, but I'm not sure where on the bit it is referenced to. I've read the text a few times trying to derive meaning but I am still unsure. Perhaps a small graphic would be helpful. The "gif" is great, but how many times? how do you keep both sides even, is there a check that is full proof? A video showing the whole process from start to finish would be very helpful.

    Laundry Room Monitor

    Hi, good read, great info to make me think, my 2 cents worth as to the current sensor, since you're "in" the wall anyway. I'm thinking you could hook the current sensor up to a line as it separated in the outlet box for the dryer. There is already bare wires in the electrical box, the cable could easily be run within the wall. It would have a few advantages, out of sight, less prone to damage, by errant socks, no need to damage the dryer cord. and then would work with any dryer you plug in, in case you have to replace it, ...or move.

    Magnetic propeller balancer

    My father used to build wood propellers for small aircraft, late 1950's through the 80's. This was the same "type" of tool he used, but on a smaller scale. He used a couple of vertical 2" x 4" 's about 4' tall on wood base to hold them up, with a couple of old wheel bearings. You just need to hold the item you are balancing in space. I've also seen it done with two pieces of wood with a notch on the top of each to hold a rod. The propeller does not need to be vertical, it can be horizontal as well, it just needs to be able to move freely. The second "must be" is it has to balance through the center axis. Which is usually a hole, so you have to create something to center in the hole. The use of the cones from the ends of couple of pens to center the p...
