    Compact Dust Collector

    Harbor Freight has a decent dust collector that I use with a 55g barrel with a tornado top that I got somewhere, I think a woodworking store. This uses 4" hose, and like this 'ible the barrel fills first and the filter gets very little, mainly tiny particles.

    How to Flatten Boards With Just a Planer

    A torsion box that is 2" thick is roughly as rigid as a 2" thick board but much lighter. The reason is that almost all of a board's rigidity derives from the surfaces and is increased by the distances between them.

    Great 'ible and a great method. I've been doing this for a while. Two comments to enhance, possibly:1) Once in a while the glue will break free, usually by pushing the board backwards on the sled. I added a thin cleat at the back end of the sled to keep the board from moving backwards to prevent this. 2) you can make a simple torsion box sled simply by gluing thin sheets of plywood to front and back of a scrap piece of foam insulation board. Glue them on your flattest surface.

    Fidget Centrifuge

    Brilliant! I'd have used this every day when I was in the lab!This reminds me of the 'card spinner' that is used to spin hematocrit capillaries. This is a disk of cardboard with holes punched to hold thin blood capillaries. It's powered by a loop of twine through the center, by intermittently pulling the loop apart, the disk spins left then right. Your device could similarly be powered by looping through the middle (without the bearing).

    There is a commercial device that does this, called the AirFuge. The rotor is about the size of a walnut and the tube hold 0.4 ml. It reaches tremendous speeds (60k RPM as I recall) and the decompressing air keeps the whole thing cool).

    Bed Slats Improvement

    Gluing the slats down makes the frame less movable, and the cross-wise glue interface will weaken every time the wood moves mechanically or with weather. The best slat frames are held in place with unglued dowels. You can use your plan for setting up the slats, and then drill a hole through the slat into the frame, before dropping a short dowel into the hole (perhaps with a drop of glue at the bottom only). I agree that some fabric beneath the slat will prevent creaking when you move in bed.

  • How to Clean a Bathroom (with 6 DIY Cleaning Product Recipes!)

    Several of these and other homemade cleaning recipes mix chemical bases (washing soda, baking soda, ammonia) with acids (vinegar, citric acid). After an initial reaction, the solution will be composed of a salt and a reduced activity of both the base and the acid, i.e. the ammonia and the vinegar will form ammonium acetate, a rather innocuous salt, and neutralize both the acid and the base. I wonder if the recipes would work better with *either* the acid or the base, rather than both?

  • How to Bend PVC & Make Incredible Shapes

    For acrylic sheet people use strip heaters to soften an area of sheet clamped to a bench, and then bend it much like a sheet metal brake. You can use a propane torch but it's easy to singe it and the area of bending is not as confined.This trick for PVC pipe is pretty clever, and is likely the only approach that doesn't risk kinking the tube. I have deformed PVC pipe with a torch (i.e. to pinch a constriction near the end) but it wouldn't suffice to bend a tube like this.

    How To Hide a Wall Wart Transformer

    "Sometimes just wires going to lighting fixtures directly without outlets..." That's exactly how it's supposed to be. Another comment suggests that all wire has to be sheathed in metal, which is not so. Plastic coated Romex is to code and used in new construction. The important thing is that the connectors have to be in an approved plastic or metal box. That is what is (or should be) under your ceiling light fixture (not an 'outlet') and is what this person did in the extension of the circuit to a separate box that looks to be of approved type to me. Low voltage lines are run all over homes without boxes; think about your 24V doorbell wire. No, they, shouldn't be in boxes with 120/240, but they don't need to be in separate conduit.

    That does sound like a different situation. All connections should be in a closed work box, but a modern plastic cable needn't be metal sheathed. Assuming you would still want the powered cable to your light (and that its in the ceiling), you should go to the home store and get a "ceiling electrical junction work box for old work". This will likely be circular or octagonal, and will have a way of securing it to the ceiling flush with the drywall. You can then run the wires from your light to that box, put the cover on the box, and paint the box to match the ceiling. You aren't allowed to cover a junction box with drywall, since it has to stay accessible, but the box is usually hidden by the ceiling fixture. If you don't want to do that, you should find where the powere...

If you don't want to do that, you should find where the powered cable originates, and disconnect that. It's likely at a switch box. You can leave the unpowered cable in the wall, though I'd suggest labeling it 'disconnected'. I didn't mean to make it sound like 'anything goes' in home electricity; code is there for a reason. However, it is unreasonable to think that all boxes and conduit has to be metal, these days.

    I'd use a wide mouth (e.g. juice) bottle with the same principle.

    Bravo! Having invented not a few mousetraps myself, this trumps them all, and all of the commercial options in terms of simplicity, reusability, and and humanity. A 'humane' trap is not only for 'haveaheart' but because cleaning up a bloody or soggy mess is never fun.

  • End Grain Cutting Boards from Scrap Wood How-To

    Looks great, the only problem is that Christmas is upon us so it will have to be next year's presents!Years ago I made an end-grain chessboard with 1/2" thick 2.25 inch squares. I had a major problem with checking and cracking with changes in humidity, and it wound up in the fire. Since then I have learned about PEG (polyethylene glycol), a food-safe waxy material that enters the wood pores and prevents shrinking and cracking; woodturners use it for bowls, usually starting with green wood.Have your boards shown any cracking? Have you or others used PEG as a first or final finish?

    Resin and Star Anise Jewlery Set

    Very nice, and quite satisfying to wear spices. Can you smell them when it's finished? Nutmeg has an interesting pattern, a cross section of nutmeg would be nice too.One suggestion on your otherwise excellent discussion of resins: Polyester is a resin that is commonly used to make fiberglass, together with glass fiber cloth. The resin itself is just polyester resin, and is hard, as you say. Some people also make fiberglass with epoxy, especially in the boating industry.

    Spectra Loop Splice

    While this is likely to hold for anything you might use it for, the proper knot for 12 braid hollow core line (like Spectra) is the Brummel splice. In the knot you use, the tail could conceivably work its way out by reversing the steps you use. The Brummel passes through the line twice (as this one does) but once by the head, and once by the tail. Thus it is not reversible. This means you need a free head and tail, but there is a way of doing it (really clever) by everting the pass throughs and then re-verting them to make the proper knot. There is an animation at Greg's knots:www.animatedknots.com/brummel/Done this way it doesn't need a whipping (not such a bad boy) but a good whipping does look pretty classy...Thanks for showing the tricks about a wire fid and the nice whipping de...

  • ESP8266 $5 internet connected switch - improved

    There should be no need to use an IoT cloud for this. One 8266 module as 'server' to control a relay, another receiving pushbutton input, and an android device that can program either and control the circuit remotely. The future is not turning on a desk lamp from your smartphone, but designing houses that don't need 14ga copper going to both the ceiling lamp and two separate wall switches. I want to be able to turn on my lights even if easyIoTCloud goes out of business!
