  • bruce.desertrat commented on tonyfoale's instructable CNC & Manual Touch Probe.7 weeks ago
    CNC & Manual Touch Probe.

    Why not just a rigid continuity probe? connect a wire to the stylus, bedded in Delrin (or even epoxy) in a suitable holder, with one wire connected to the circuit, connect ground to the workpiece (or the mill table) and detect when the circuit is completed. I'd think that would give the desired minimum pre-travel with most accurate location.

  • More 3D Printed Gadgets for Woodworking

    A version of that bar gage is the first useful thing I ever made on my 3d printer and was a tool made kind of on the spot. I had to replace the diffuser panel in the fluorescent fixture above my kitchen sing and couldn't fit a tape measure into the space. Whipped it up and printed it in about 30 minutes.It takes a pair of ordinary takeout bamboo chopsticks. The rectangular back end fits in snugly (you may need to rim them a bit with an Xacto knife or razor blade) and the rounded part slides right through. Worked like a charm.Yours are MUCH nicer! There's several things here I could use. Thanks!

    C-Mount Web Cam Mod

    I suspect using black ABS instead of white PVC would improve the image quality. I'm very interested in this; I' currently trying to keep a piece of 1990's gel imager alive in a lab where I work. The device has a really nice c-mount lens on it, and a CCD that only works with an antique frame grabber card that I can no longer find drivers for.This has given me a leg up on a solution! (and a first, getting PAID to follow an Instructable! :-)

  • Homemade Fly Cutter - From Scrap Steel

    Nice instructable, it gives me confidence to try milling on mine. However, why not just shim up the headstock by 1 mm to fix the discrepancy? I'd think that would be simpler than milling down the tailstock, as that will be quite difficult to mount to keep it square during milling.

    Magnetic Laptop Mount

    Any magnetic fields generated by these that get through the case to affect the drive will be several orders of magnitude less than the fields generated by the extremely powerful magnets inside the hard drive. I have magnets harvested from old SCSI server drives that will hold bout 50 sheets of paper to a refrigerator. There's no danger whatsoever of these magnets affecting data in the laptop. If the laptop has a spinning hard drive, the vastly greater danger is it being jostled around on a construction site!

  • Low Cost Adjustable Rail 4x5 View Camera

    The November 1933 issue of Popular Mechanics has a nice article on making your own camera bellows. It's a little more (ok, ok, a LOT more :-) complex than yours, but it ends up being a 'proper' cloth bellows, which will probably last longer: an aside I heartily recommend spending some time perusing all those back issues; it's truly amazing to see what people were making with just hand tools, and just how often the wheel's been re-invented :-)

  • 'Shave Mouse' Aka Revisited Shave Horse

    Neat concept and I'll always applaud approaching things like 2000+ year-old-designs with a fresh eye!One of the reasons shaving horses are designed the way they are is you don't have to get up to change the position of the object being worked on. You simply let up with your legs, reposition the work right in front of you, and push again to clamp it.In your design you have to stand up to do that. A traditional design lets you sit down the whole time. Lazy always wins :-) Also a traditional design puts more clamping force on the object the harder you pull, because the natural inclination to use your legs to exert force. With this design you have to drink enough beer to put on more weight to increase the clamping force...a slow (if pleasurable) process!

(They're pig-like critters about 35-65 lbs and travel in bunches. They can be quite aggressive and they pack 3" fangs; not much messes with them.)

    Landscape Rock Tumbler

    1) Always Add Acid To Water. This is the first rule you learn in chemistry class. My 7th grade science teacher memorably demonstrated this: He had a huge beaker set over the sink with a liter of concentrated sulfuric acid. He then dumped a couple hundred milliliters of water into the beaker. It started to boil vigorously almost immediately; and it stayed at boiling temperature for most of the class.Muriatic acid isn't too harsh to work with; I've used it (diluted) to clean mortar haze and water stains off of bricks many times. Rinse off the rocks after scrubbing with a baking soda solution (that will foam up excitingly, but is harmless), then finally rinse with water. Before disposing of the muriatic acid solution down the drain, dump in baking soda to neutralize it.

That's a beautiful mallet, although I'd be tempted to make one face out of something like a piece of a polypropylene cutting board turned to fit, or from some milk jug stock a' la kludge77. Perhaps make an insert recess in one of the faces to hold a round of PP.That would give you one soft face to avoid denting whatever you're hitting.

    Marking Gauge for Woodworking

    My firewood pile :-) I did some major pruning of a couple large mesquite trees in my yard a couple years ago and got several long chunks of 4-5" diameter branches, and the Italian cypress came from a tree that died on the property a few years back. None of it is sufficient to make big things, but for small projects like this or small boxes, etc, it's great.

    This was the cypress last week after the tree service took it down. The wood smells wonderful, and is very hard and dry, since it's been standing dead for a few years. As it's cypress it's really rot and termite resistant.

  • Bike Pannier from Scratch Using a Home Sewing Machine

    When I made mine, I used a short 'mending plate' I got from my local Ace, fixed most of it in my vise, then hammered one end around a properly sized rod to make the J-hook. It was easy to round off the corners with a file, and if you really want plastic on the end, a small can of 'Plasti-dip' is cheap, and will find endless other uses around the home, shop and bike (like dipping the cut ends of newly installed brake and shifter cables, to keep them from fraying, because I can never find those little top-hat crimp-on ones bike shops use.

    When I made my own set a long time ago, I found a large 3-ring binder getting tossed out. The vinyl-protected covers worked very wellas stiffenes for the back, replacing your $$$ plastic. if you sandwich them into the fabric or simply rivet them on on the inside of the pannier like I did, the cardboard won't get wet and disintegrate.Those panniers lasted a long time, but eventually the already-20-year-old army surplus knapsacks I made 'em out of disintegrated from the sun :-)

    As ssterman says a jig for a hand held router would work pretty well. If I were to do this by hand (also an entirely doable proposition...look at what craftsmen over the centuries have done with nothing more than hand tools and patience!) I would first make a custom punch/chisel of some sort to outline the squares. The same one could be used on the tiles to make the letters. An appropriately sized piece of square steel tubing would work admirably as a starting point.

  • bruce.desertrat commented on ClenseYourPallet's instructable Hardwood Rug2 years ago
    Hardwood Rug

    One way to avoid the the 'one break and it all falls apart' problem would be to knot the twine between each piece, like they do pearls on a strand to prevent the same thing; everything falling apart. The construction method would have to be different, though to allow this, and I'm not entirely sure how to go about it; I'm just spitballing here..

    Another thing that would help (and make it more difficult to make!) is to cut a small kerf from the hole to the end of each piece for the exposed twine to set in on the outside edge pieces; that way it will be protected from wear somewhat. This is how leather stitching is done: you make a groove in the leather for the thread to rest in and it isn't worn down by things rubbing against the leather. This would also make the edges a little neater in appearance on the finished project. Now I just have to find some hardwood scraps that seem to proliferate in everyone's shop but mine :-)
