    At my age I'd be risking ****tin my pants if I tried to force a fart. I suppose it would have the same effect in a supermarket aisle though-

    If people are exhibiting no concern at all for being in the way of others, then I think a well-released fart would be in order. Maybe add a couple words just to show some concern yourself- like 'ah,...

    Don't remove the impeller. Put the whole thing in a press and bend it straight. You can probably see the markings from the impact which bent it in the first place. If you have access to the other end...

    I would look at anything Dan Gelbart has to say. Very interesting guy, and very well founded in his field- which covers a wide area.

    I have the 3 in 1 machine, and I find it almost useless. I have 4 other purpose-built benders that handle either thicker stock, or make tighter bends, or make bends up to 270 degrees, etc. One of...

    Personally, I would put the contact area above the bearings. Even if you insulate the shaft from the bearing ID, the current flowing through the shaft would tend to magnetize the bearing, and maybe...

    One we had at work used a 110 vac winch to haul a cage up to a second floor. It was self-holding but slow. Twice the magnets in the motors came loose, and there wasn't going to be a third escapade...

    I saw the video where they launched the end of a roll of wire into the air- with the subsequent lightning strike, etc. Pretty cool. Often wondered if it would be possible to launch a vortex donut...

    After all this derusting of tools, an immediate application of a protective coating is desired. I'm reminded of something we used to put on our hands before spraying lacquer or staining. Might have...

    There's probably a few generalities that would more or less cover it. One is that the pilot drill size should be about the same diameter as the web diameter on the following drill bit, or maybe a tad...
  11. how to make a nice hole in thin stainless sheet

    Today I made some hold-downs to spring-load power transistors to a heat sink. These are stainless steel strips, just over an inch long and 1/2 inch wide. A hole near one end lets a potentiometer bolt...

    I agree that vibration and levelling are mostly unrelated. I think you need to determine what is causing the vibration and treat that as a separate problem. It is possible that the rubber mounts...

    Find yourself a 1/2 inch router that you can use for the spindle and bearings. I see them from time to time with burnt armatures, etc. You don't need it to run, but the spindle nose and the bearings...

    You could try never dull on a seldom used area. It should just clean things up without removing more than a dusting of material.

    I would expect that there'd be a known procedure to follow after...

    Let us know when you find out :)

    A motor like that requires the fan for cooling, so if you slow it too much it won't get enough. You can still use it intermittently though. You can use a simple...

    unexpected gooseneck

    Got around my need for gooseneck tubing, but during the process of looking for it I ended up buying a few Snake Lights, a Black and Dekker product. These all came from thrift stores so weren't much...

    I like the idea of the safety sleeve. If you could possibly use the idea of stacked glass 'washers' placed around the cylinder it might look pretty cool. How the heck would you implement cooling...

    What Ringo said is very true. I like to see banana plugs with multiple points of contact, and spring clips with both pieces of the clip connected to the wire. I'm happy when I see a very consistent...

    Years ago my boss bought a Corolla. All the kids drove it at one time or another, and nobody every changed the oil. At 7 years old it seized up on the highway. That was before synthetic came into...

    I've always thought that a bottle jack would commonly use pressures up to 10,000 psi or so. Maybe I'm wrong, but if I do the math using the diameter of the ram, it seems right.

    Starter motor brushes will have very low resistance, which in this case means more of a direct short between windings. The whole idea of the layered brush assembly is to lessen the current drawn by...

    I used vacuum cleaner brushes. Lots of meat there usually, and I did break some pieces so the longer brush gave me enough to work with.

    Carbon brushes designed for high current, low voltage motors often look to have some copper content. I'd expect these to be a little more work to slice, but the straight carbon ones are easy. I used...

    My lathe, which is an 8 x 18, has the flats and one V on the headstock. The V does not touch down on the V way, so it is not aligned by it- there are set screws for the alignment. If I ever remove...
