My big hobbies are working with wood and metal. And I stay busy. I've built various pieces of furniture that have been included on the Wood magazine subscription card, and featured on a television show in Europe. I've sold artistic blacksmith pieces and knives with leather sheathes, all over the world. I've scratch built machines from 20 ton hydraulic presses to 5hp belt grinders to Arduino controlled heat treat ovens to tandem axle trailers that hauled 12000 lbs cross country and up rut...

    Anvil came from a guy on Craigslist, it took a while for one to come up, but I finally grabbed one.

    Overlapping Tandem Barn Doors

    Glad to see you made the jump from buying metal at big box retail to a good metal distributor. If you don't already have one, I'll bet there is a MIG welder in your future. Nice doors.

    Skinning Knife from Leaf Spring

    I've been using propane for a while now, but I really like that leaf blower hardwood forge. I'm guessing that thing could get hot enough to burn up your metal, or forge weld if you wanted to.

    I made one of these when I was a kid, but we used charcoal lighter fluid. This looks safer.

  • 10 Items to Keep in Your Vehicle During the Winter

    Depending on where you drive, particularly if you have a chance of getting stuck on a closed interstate highway, you might think about a couple other things.- A good first aid kit with an ace bandage.- A fire extinguisher.- An inexpensive stove that works with esbit fuel tabs.- Some hot chocolate and a couple dehydrated meals.- Yaktrax in case you have to walk.- Travel size toilet paper.- And my optional faviorites: a camp axe and a deck of cards.

    That would be fun with a burner pilot and some propane in the air mix.

    Constructing a Robot Arm

    Yup, there are multiple solutions to reach the same position of your end effector. But what happens if both motors are turning at the same time? The elbow motor creates a second order effect that amplifies the joint torque on your base motor beyond what would be applied by only rotating the base motor with the arm fully extended. If you didn't work that out in your kinematic equations, it might make sense to only move one motor at a time.

    3$ Photography Lightbox

    I'll let you in on a little photography trick I figured out. Turn off all the lights in the room, put your camera on a tripod with the shutter open, use an LED flashlight to paint in the shadows. Hold the light in the first position (usually above the subject), count to five and watch where the shadows fall, then point the light where the shadows were for a couple of seconds each. It takes some time to figure out the camera settings, but it will make your box look like you have five different floodlights pointing into it.

    Constructing a Robot Arm

    I like your double sided bearing explanation, and the nearly art noveau style of the sheet metal. But the joint torque calculations assume that the rotating joints at the base and elbow would never be moving at the same time. Is the controller programmed to prevent that?

    Mortises Made Easy

    Nice write-up. Just yesterday, I chopped a big ole mortise through hard maple. A marking gauge and/or marking knives do a nice job of making a little trench for the chisel to catch, and help leave a crisp edge all the way around. To establish a straight line, I like to use a really wide chisel for the first chops, then switch to a smaller chisel past the first fraction of an inch.Marking knives can also make a nice little trench to help keep a forestner bit from wandering. Not saying one way is better than the other, but I like to hog out the material first, then the first chisel strikes that establish the edges cut a little deeper.

  • A Different Ball Turning Jig for Taig Lathe

    This would be a nice tool for my HF 3-in-1. I think I have some inline skate wheel bearings I could use. I'm picturing shining steel replacement balls for the factory black plastic balls on my drill presses.

    Leather Tool Kit

    Thanks. I considered doing a Sheridan style, but it just isn't my taste. That, and so many people are so good at it, my work looks amatureish by comparison.

    I wasn't sure who to credit for inspiring the design, but I am now. Thanks. I just saw an unattributed photo on Pinterest and used it to guide a sketch, but searching his name came up with more gorgeous tooling. The bottom layer of the design is a trace of microscopic photograph of a human eye. Once, I did a sheath for a knife I forged that was tooled to be an anatomically proportional bat wing. I like patterns from nature.

    DIY Router Fence

    Here are some of my tips:- When using pilot bearing bits, make sure the bearing is pushing against a smooth edge. Any bumps, glue specks, saw marks, etc, are going to telegraph onto your routed edge. A jointer, hand plane, or a long sanding block can used to clean up the edge.- When using pilot bearing bits, don't push too hard on really soft woods like white pine, aspen, or anything you can mark with your fingernail. The bearing can push into the wood and make a wave in your routed edge, and leave an ugly mark on the work.- Don't try to take all the material off on one pass. Take multiple light passes, or increase the bit depth a little bit at a time.- When using an edge guide, watch for sawdust to build up on the edge between the router base and the straight edge.

Take multiple light passes, or increase the bit depth a little bit at a time.- When using an edge guide, watch for sawdust to build up on the edge between the router base and the straight edge. It can throw off your line. Metal edge guides work best, aluminum works really well.- Not all router bases are perfectly round, or centered over the bit. Try not to rotate the router as it slides along a straight edge guide.- End grain can be routed, but it makes a difference which end you start on. You want the router bit pushing the grain into the board, not pulling it away. Clamp a piece of scrap against your workpiece to keep the grain from splitting away on the other end.- Don't plug in a router without holding it in one hand. They have so much torque, if plugged in with the switch turned on, they will jump off the workbench and dance around on the floor.- Don't push the bit all the way to the bottom of the chuck, and make sure the chuck and bit are clean and free of sawdust. This will help keep your router bit from starting to work loose.- Wear shoes, and a face shield. Routers can kick big chunks of wood under safety glasses. Plus it keeps sawdust out of your mouth.

    I usually use a clove hitch for tying around round objects like trees, but I like this better. It looks easy to remember.

    Hen Shape Sculpture- Rooster Cage

    There is a guy selling a full scale horse sculpture on my way to work. I wondered how he did it, and suspected he maybe used a projector to create full sized templates. But I didn't consider the perspective of looking down from the top. Thanks for the info.
