This saw guide is a welder's spare hand! I installed magnets in the aluminum straight edge. I can easily cut steel plate with my Milwaukee Metal Cutting Saw. The long guide has over 500 lbs of clamping force, more than enough to keep the cut straight even cutting thick plate steel.

This ain't your Pappy's party trick. Arduino powered EDM (Electric Discharge Machining). I've been working on this all week and finally got to a working proof of concept. You'll get to see the full length vids detailing the build, stupid mistakes, getting electrocuted and eventual success in the coming weeks. Don't be shy, please click "Subscribe" THANK YOU!

Let's hearken back to a simpler time. Say, last night? When Thomas Edison inspired me to improve upon the 200 year old design of the carbon arc lamp. Made possible by two pencils and an Arduino. Honorable mention to Dangerous Prototype's ATX breakout for supplying the 12VDC and 0.5amperes. Also, thank you goes to a class act, Ian Lesnet, for the prompt and kind PFO to a request for free stuff. Hey, ya don't ask, ya don't get. Remember the little guys at promo budget time! Post Script: If only Texas Instruments hadn't cut me off the free sample gravy train, it could have been "Now with more MSP430!" Catchy, no?

This is what happens when you don't take precautions when drilling bronze. Best practices: Brass off the drill Light feed pressure Ensure chuck is tight so bit won't pull if it grabs Apply a little quill lock pressure to prevent self feeding if drill grabs

*This is incredibly dangerous - the scabby tools and cobbled together parts shown here are widow makers. Treat them as such.* I'll show you how I machined a portable die press for punching and broaching. We're using the latest in Armstrong technology to build a hydraulic press, without hydraulics! 100 tons for 100 dollars in material.

Allen keys are S2 tool steel, so they make dirt cheap punch dies. Here's how to make tool steel dies for your press. Sockets are dangerous in this application, you'll see why in a future vid. Don't come crying to me. Safety blah-blah *ad nauseum*.

This is a percussive drill bit for rock. It goes in a hydraulic hammer, just a *little* bigger than your typical Hilti rotary hammer. It has tungsten carbide buttons that I'm trying to remove. Any ideas?

The rock crusher goes kaput. We investigate and find that our stover nuts let us down. So we add hard face weld to the impact hammers and re-assemble.

This is a simple micro-controller brain that controls a hydraulic valve. It reverses the valve when it sees the pressure spike in the crushing equipment. This allows it to automatically clear jams. I want to adapt this to a homemade log splitter. I've never built a logsplitter; please post any stories/ideas/questions you have. Big rocks get broken down with great bloody maul, get jammed into the hammer mill, are gravity fed to the rod mill. The rod mill grinds the 1/4" minus ore into 50 mesh, the oversize comes out the classifier and get re-ground, the 50 mesh minus slurry gets pumped to the shaker table. The shaker separates the particles according to specific gravity; gold, silver, lead, copper, iron on one end, shmoo on the other. Just something I whipped together on a lazy Sunday after church.

I can't find a use for this milwaukee oscillating multi-tool. Can you?

What is Flow Drilling - Friction Drilling - Form Drilling? Whatever you call it, it's cool to do it yourself with salvaged tungsten carbide. This technique allows you to thread holes in thin wall tubing without inserts and without welding using the dullest drill bit ever.

Build your own simple tool for broaching square, hex, keyways and holes in metal.

Extra special shout outs to these great guys, thanks for your help! https://www.youtube.com/user/nik282000 https://www.youtube.com/user/icc3a1800 https://www.youtube.com/user/AlexSprites Thank you for watching and contributing! We look at some of the lessons learned from our journey to one million views. Including how to deal with Trolls and how to build yourself a bronze plaque with a cold chisel and hammer. *SFPODBA Disclaimer* "The Society for the prevention of drill bit abuse has approved this video.

Wood and urathane rubber base for an old family heirloom. This anvil base will last another 100 years. I'll show you how I potted it in cast urethane on a wood base

How to recover tungsten carbide from drill bits. This is a rock drill bit with tungsten carbide buttons that we'll use to try a couple of removal techniques.

How to woo the ladies: service their car! How to fix pulsing brakes. We use the Bridgeport milling machine and Starrett rear plunger dial indicator to troubleshoot a tough-to-diagnose brake problem. We also bodge a Dewalt sander in order to do the job.

*Behold!* The must-have ultra luxurious, bleeding edge techno gadget for the more-money-than-brains-Louis-Vuitton gearhead crowd. Ultra exclusive offering; population: You. I'll show you how I drilled, milled, glued, acid etched, copper and gold electroplated this one of a kind drill press oilcan. It's a real handy tool to have around the shop. Heavy gold plated steel with magnetic base and brush retainer, ensures it won't spill during heavy cuts. The high performance, stinking-rich-grade gold electroplating ensures instant heat transfer to eliminate heat build up in high performance cutting fluids.

This is an easy way to make pennies float. It's quite surprising to see copper float on water, but there's a simple explanation. If we change the density of the copper penny, it'll float!

A funny little trick to crush a penny after you've grown bored of watching the copper float hack. Caution: Lame Science at work.

A brief explanation of digital multimeters (DMM). You get what you pay for. What to look for in a meter for troubleshooting cars, trucks, hydraulics, AC, DC, motors, electronics. For $150 the Fluke 117 or 113 are solid multimeters that'll last you *decades*. Best of all, they won't screw you up with random auto-ranging and obscure nonsensical displays. You need to be a genius on Adderall to troubleshoot with a "value priced" meter. Give your brain a hug and throw out those crappy meters lying in the bottom of your toolbox.

I'll show you how to sharpen most drills without any fancy jigs. When you need to sharpen a twist drill on a jobsite, sometimes you have to make due. We can't always be in a nice warm, well lighted shop, with a perfect grinding stone and a drill scale. A little practice and you'll be able to sharpen bits under nearly any conditions. Be forewarned! You'll hear newly minted-shop-machinists clucking and tsk-tsking in the comments. Never you mind, because they never stray that far from the coffee room. This'll help you get it done! Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds. (pun indended)

We test out High Speed Steel for flow drilling and for friction welding. I inadvertently discover a breakthrough hangover therapy: getting milling machines to do what they're not designed to do.

I'm interested in hearing your thoughts on a new vid series, please comment! The new segment will feature short vids based on the question: "which one is better?" This is WoiB 001. I've been using this Hakko 888 soldering iron for the past year. It's got 70 watts, so it heats up faster than the Weller 52D. I've got this Hakko on the bench in the shop. I've got the Weller upstairs on the electronics bench. Sure, the Hakko is a nicer iron, cooler looking, higher capacity but the real difference is the price. The Weller is $225, the Hakko is $100. Better and cheaper!

Inspired by Shopdogsam, mrpete222 (tubalcain) and Dave Jones, I set out to build an electric solenoid engine. I quickly find out that adding variable speed capability to existing cam and switch governor isn't as simple as it sounds. I start out with the easystepper board, move on to electromechanical relays and settle on transistors driven by a micro-controller (MSP430 LaunchPad) to achieve reliable speed control for a yet to be built model engine.

* Danger: I have no idea what nasty chemicals might come off this super heated magic sand. Use your head! * According to this MSDS, formaldehyde is produced above 150C. You need good ventilation and a properly fitted organic vapor respirator! http://lubixcube.com/FAQ_files/LubixMSDS.pdf This new and easy procedure for casting aluminum is ridiculously simple. You don't need any special casting equipment, just a welding machine some graphite and some kinetic sand (silly putty in sand form). In this vid you'll see me set up and complete my first ever aluminum pour in a matter of minutes. The key is getting rid of all the complicated furnace and sand casting equipment. Instead, I'll use a stick welder and some play sand from the toy store.

http://youtu.be/mooOBhYJeI4 Battleshots, a drinking game ripoff of Battleship from Milton Bradley. Sue me at your peril. I tackle THE question of our age. Why can't they make a good trimmer head? I've got the best trimmer I could buy, according to the reviews, the Stihl FS 38. It's a skookum power tool, but the cable head doo-dad will drive you to drinking! In the process, I stumble upon the next extreme sport.

This is a cut and roughly polished section of the first aluminum casting using DC arc, graphite and kinetic sand. Some bubbles in the upper part, but not bad, all things considered. I've left plenty of room for improvement.

I built myself a dirt cheap lapidary rock tumbler. It also works great for removing rust, deburing machined parts, and getting rid of old paint. It's ah slower than sand blasting, but works well. You can use sand, dirt, walnut shell, sawdust to prep parts for painting, electroplating and anodizing. As a caveat, Tumler is made in the USA and is clearly a skookum product. If you find yourself in need of a good tumbler, there are clearly none better. http://www.thumlerstumbler.com/ Also, I'd like to say that I have many wonderful ex pat Chinese friends and a few still living there . But the country is a toxic dump, both morally and environmentally. I've worked dozens of projects there, and been there during baby formula melamine poisoning scandals.

Sign up to win free Tactical Keychains swag! http://tacticalkeychains.com/?ks_giveaway=free-tikey-share-to-win And the winner is: FREE TiKeY Winner – Brandon Masick Congrats! We use some Titanium that Tactical Keychains sent in. This is using the arc welder and graphite method that worked so well on aluminum. Adding argon shielding gas to the set up ensures that the molten titanium doesn't explode. The results are terrible; but you can't win 'em all.

Wetterlings Swedish Axe isn't the best I've ever owned, but it is the most expensive. It's a beautiful piece of blacksmithing. It has a beautiful handle. But the design of the head only makes it suitable for light work. I'll use this for prospecting, but it's not good for any real splitting. It's good for light chopping, and it sucks for making kindling. Right out of the gate, the wedge fell out. I jammed it back in and it lasted another day. Then the wedge split half in two and flew out. Game over. According to the pimply faced kid at the hunting store, this is the smallest axe / hatchet that meets the requirements for the grueling Yukon Quest dog race. Think Iditarod, only for men. Now, Les Shroud is one tough SOB, and I think he's pretty much a straight shooter, but his endorsement misses the mark. I'll stick with my $25 Elgin.

Please vote for my instructable: http://www.instructables.com/id/Easy-Permanent-Print-on-Metal-at-Home/ But what's in it for you? When we win, I'll be giving away an Ipod and a Dremel to lucky viewers! I use a laser printer resist and ferric chloride to permanently mark electric control box. This technique allows you to indelibly print on any metal. It looks very professional and the more careful you are the better the results.

I build the calculator kit that was featured on HaD. Nothing says I love you like a home-made dork gift! http://hackaday.com/2014/07/02/pocket-calculator-emulates-pocket-calculator/

It's easy to get gunpowder to explode, right? In the spirit of "I will"; I humbly submit: scrap bin BB cannon made from old-cheese-grade threaded rod (aka all thread, redi-rod). Too often I see fellows put up false barriers; "I can't make that, I don't have a 'X'". I long ago rid myself of that toxic excuse "can't". I will or I won't. Along the way, I dispensed with that other toxic word "should". I don't should on anybody, least of all myself. I will or I won't. I turned down the barrel with a hand drill and a die grinder. I drilled the bore and touch hole by eye. I made my own fuses with a youtube recipe that doesn't work. Instead, I made glue from styrofoam and gasoline. I procured Pyrodex FFF propellant and made my own Napalm paper fuse. I own a respectable collection of knackered machine tools. But I still like making things with a bare minimum of tools. It's a personal challenge to make "minimum viable" projects. I hope you like this work in progress. Safety Gestapo take heed, this is a good 'un. "Calling all cars! calling all cars! WooooEEEEEEEEEEE. Somebody please think of the children!" &c... As always, I welcome your comments!

I grind up some Fools Gold that contains tiny quantities of real gold. I wanted to make a copper solution for electroplating using ore I prospected. What I got was something far more interesting. The real gold floats right to the top. Impossible because gold is nineteen times heavier than water. Right? Yes and no. If the gold particles are small enough then the effect of surface chemistry overcomes the density effect. The gold picks up a positive surface charge and gets stuck on top of the surface tension of the water. This effect is used to concentrate most metallic ores mined for the past century.

This is a new and easy way to pinpoint electrical faults in cars, trucks, heavy equipment, electronics. By looking at the thermal image of electric circuits and devices, I'll show you how to quickly identify electric faults in wire, connectors, and components. I'll show you how to use a FLIR TG165 infrared camera thermometer to pinpoint hotspots and troubleshoot with a DMM (digital multimeter). Here's the link to Dave Jones EEVblog teardown of the Flir TG165 https://www.youtube.com/watch?feature=player_embedded&v=xFFXUc4Bwjs

We'll disassemble and inspect a hydraulic gerotor motor. This is a high torque hydraulic drive motor. This type of motor is on smaller construction equipment; bobcats and small excavators. This unit is broken, so we take it apart to see if we can repair it.

I'll use smooth-on industrial urethane rubber to repair a broken Dewalt Tools oscillating sander. The pad is worn out, so I make a new one. I recommend buying a new part from a tool repair shop. But this one now has a tough, custom homemade rubber abrasive pad. As an added bonus, I show you how to tint and cast open cell urethane foam. Yay!

Some tools you just can't find in stores, you've got to make them. This small radius burnishing tool is not available, so I'll show you how to make one. This DIY tool will allow you to burnish a decorative pattern in steel, copper or aluminum using little more than emery cloth and glue.

I'll show you a cheap way to make an amazingly versatile tool. Battery recovery, repair and charging Charge any battery, even if you don't have the original charger Electroplating Anodizing Aluminium and Titanium Electro-polishing Etching Electrolysis Operate DC solenoids, valves and pumps DC motor speed controller It's a DC power supply with programmable CV/CC constant voltage/constant current. A more professional 80V/5A version of this tool would cost kilobucks. We can build it for about $40, because we're not concerned about electrical spikes or noise.

Came across these little locomotive gems and figured you guys would appreciate seeing the results of two traction motors in full wheel slip doing a burnout on the railroad. Traction motors are generally 600VDC and rated for 1hr at 1600kW, but can be much higher! Gord bless the internets: http://bbs.homeshopmachinist.net/threads/65164-Locomotive-Burn-Out

http://www.instructables.com/id/Copper-Workbench/ I make a copper work surface for the electronics lab. I'll show how to score and cut copper with the help of it's work hardening properties. Then I glue, clamp and laminate the copper sheet onto a plywood backing to make a sturdy work surface. I burnish the copper to break up the wavy look of the gleaming metal.

I get "lost" on the way to doing laundry and manage to find my way into the Wien Technical Museum. Mechanical contrivances abound, and a good time was had by all. As an added bonus, this museum is a great way to avoid crowded Christmas Markets!
