    How to Make a Batch of DIY Arrowheads

    That is a cool idea. I like flap disks to remove rust. It leaves a nice finish and can remove heavy rust. That looked like a lot of work to cut them all out. I thought my son was wasting my time when we built a 4'x9' CNC plasma table, but it saves a lot of work when you need a bunch of identical parts cut out of metal.

  • Drilling Metal With a Drill Press

    You must be from "down under". I knew that water swirled backwards in toilets down there and I guess clamps get installed backwards too. My floor standing drill press goes down to 80 rpm. It prolongs drill bit life. I use Rapid Tap for steel and WD-40 for aluminum. Give me slow and a lot of force any day.

    Not really "required" but helps promote longer drill and drill bit life, makes a better hole and prevents the metal from getting as hot.

    How to Make a Scratch Awl

    Can't you just go to a yard sale, buy a phillips screw driver for $0.25 and sharpen a point on it with a grinder?

    NO. Nails designed for wood are LOW CARBON, which can NOT be hardened. If you want to harden a nail, you need carbon steel nails. Concrete nails (MUCH different than cement nails) are carbon steel and can be hardened.

    Make Your First Serious Amplifier

    I built an audio amp once. It operated off of 12 V and was used to call in varmints. We built it in the shed. It was quite loud, so we set the speakers outside and was playing a dying rabbit or similar sound. The dog that was running around the yard attacked the speakers so it set us back a little to get new speakers. They were waterproof marine speakers if I recall correctly.

    I never have used a sander to sharpen a pencil since I don't have a belt or disc sander, but I have used a bench grinder to sharpen pencils and soap stone. I have used a metal lathe to drill holes in glass blocks. It would turn slower than the drill presses (didn't have the mills at the time) by chucking the bit in the lathe chuck and using a push block on the tail stock.

    I think I would have just mounted the CNC what ever under the work bench. My son and I built him a 4'x9' (those still stuck in the metric may need to know that there are 2.54 cm per inch and 12 inches per foot) that is work bench high (30 some inches). The next one we build will be able to handle a 5'x10' piece of steel and be about 12" off of the ground. It is a little rough for an old guy and his son to get a 600 lb+ (2.2 lbs/ kg) piece of 1/2"x48"x96" steel that far off of the ground.

    My oldest son has bee using it. He even switched from Ubuntu to Windows so he could run it. He designs things in 3d, but it is great at making the 2d cut paths for a CNC Plasma Table. The best thing, is that it can tell what the weight of the finished product will be. One that he is currently building is a little over 3000 lbs and the other he has been able to trim down to just under 1000 lbs. I would be happier if he could get it down around 700 lbs.

    We have a brake that fits in a press. It will bend 19" of 1/8" and 5" of 3/8" with the factory angle iron base. We have made inserts to make tighter radii so we can't bend that heavy of material with a tight radius. When we cut parts out that need bent, we just cut line segments on the CNC Plasma table which makes it much easier to bend.

    Hybrid Rocket Engine

    It looks like a pipe WITHOUT the BOOM to me.

    That seems more like burning paper in an oxygen rich environment to me than a rocket engine. When I was in highschool, in the shop, we found an old wooden spool of solder (about a 1 lb spool). We stuck it on the end of a lighted oxy/acetylene welding tip. As soon as the wood started burning, we turned off the acetylene and cranked up the oxygen. It made a cool flame. I didn't know it was an rocket engine. You could emulate the same thing for a lot less cost and time buy just drilling a hole through a piece of wood igniting the wood and blowing oxygen through the hole. Seems pretty safe to me as long as you don't catch your &*( on fire. We all know that oxygen does NOT blow up and ONLY supports combustion.

    If you have a 10kw generator, it will have a 50 amp breaker on the generator. If you wire it to a 30 amp dryer circuit, the 50 amp breaker will do NOTHING to protect the dryer wire, but the 30 amp breaker in the box in the house WILL protect the 10 ga wire going to/from the dryer receptacle.

    I have a big expensive (for home shop standards) drill press. I bought a 5" milling vice from HD for less than $100. Obviously it is not good enough to mill with (and I wouldn't want to destroy my drill press milling steel) but the vise it good enough to position the material to drill or tap holes. All milling is done on the mill. You should probably use a hard wood for the parts that slide and put paste wax or burnish the wood where it slides and the most precision is needed.

  • 6.3 kiloWatt Ground Mount Home Solar Array

    I have thought about installing solar panels. We don't have an AHJ to deal with. I am not sure what I would have to do with the electric co. They seem to be easy to work with. When I moved here, they installed a pole and told me when I was ready for electricity, they would have someone stop by and install the meter. They also told me that If I need to turn off the electricity to just pull the meter and tell them to stop by and install a new seal when I was finished.

    Darth Vader Wood Burner Remix

    We always fill fuel tanks with water when cutting them. I had never thought about it, but when we were cutting a gas tank on a junked Ford Explorer (but of course what other kinds of Ford Explorer are there) with a plasma torch, my son got a good shock when the torch got wet.

    Make a Massironi shelf

    How much does the shelf weigh? I don't have a band saw or nice sander like that. I do have a CNC Plasma table. I was thinking about making one out of 16 ga steel. I know cold rolled steel is 18.6 times as dense as pine, so 16 gauge steel should weight about twice as much as 9/16" pine.

    I use LibreCad. You can draw full size, or to scale. When you print it out, you can scale the printout or print full size.

  • Start Fires With Electricity: DIY Arc Lighter

    I made one a long time ago with an automobile coil, a relay, a capacitor, and a 12 V battery. It was portable. Mostly made it to make sure that defective parts that I sent back for warranty replacement were determined to be bad by the vendor.

    Blacksmithing Forge

    Cool, he has a band saw. My son keeps talking about getting one but I have run out of room in my shop. It would have been nice to have a band saw when we built a 4'x9' plasma table. The chop saw wasn't accurate enough and I had to cut 42 pieces of 2x3x1/4 tubing with an angle grinder. At least everything was within 1/16" when we got done.

    A forge is the thing that heats the metal. Forging is the process of transforming the metal.

    Concrete Coffee Table

    Probably the easiest would be to get a block of wood that is twice the width and length of the radius that you want for the corner. Then drill a hole in the center of the block that has a diameter of twice the radius of the curve. Then you get four pieces of wood with the correct radius that you can tack into each corner.

    How to Weld - MIG Welding

    You must maintain the correct and uniform distance from the nozzle to the work. You adjust the wire speed to keep the wire from hitting the work too hard.

    Oxygen is NOT combustable. You need to open ALL valves fully except for fuel valves (acetylene and propane) because some valves do not seal around the stem when they are partially open.

  • How to Remove a Stuck Nut (without stripping threading)

    This has a lot more to do with how to hold a threaded rod without destroying the threads than it has to do with removing a stuck nut. This is only ONE instance of a stuck nut. I found this instruct-able and was severely disappointed. A more responsible title would be "Securely holding a threaded rod". The only decent rust penetrating "oil" is Kroil. Also, when you clamp the locked nuts in the vice, ONLY clamp the one towards the nut you are trying to remove. If you notice in your picture, the flats on the two nuts are not aligned. When you clamp both, you can either loosen or overtighten the locking nuts. By holding the inside nut, it self tightens itself against the other nut.

  • Simple and Durable Hydroxy Gas Generator

    If you want to keep the hydrogen and oxygen gas separate tor try to use if for a torch and mix it at the torch, you can separate the anode and cathode horizontally. Oxygen will form at one and hydrogen at the other (it has been over 30 years since I got my BS in Chem and I have never been employed as a chemist or I could tell you which would form at which electrode.) Just collect the separate gases at each electrode, and mix them where you want them.

    Smoked ribs in the smoker

    I smoke a lot of other stuff, but to me, smoking ribs does not enhance them in any way. If you notice, the above cooking takes almost 3 hours if not more. I run the grill about 250 degrees, so it is low and slow.
