    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.

    With concrete, 'cut it' is properly refereed to as screeding.

  • 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.

    How to wire a 240V AC outlet

    Dude, you don't have a ground in that box, only a neutral. You can't wire a NEMA 6-50 to that box. You did get lucky on one part. 8 ga is ONLY good for 45 amps, but with a welder, you can de-rate the wire. YOU have to put clamps on the wire where it goes through holes to prevent the wire from pulling out and rubbing to wear away the insulation. You also mount your recepticle in a box. I ALWAYS use 6 ga wire and 50 amp breakers for wiring a NEMA 6-50 or 14-50.

    Since the two blades of the recepticle are both hot, it does not matter.

    Smoked ribs in the smoker

    I used to go to the trouble of smoking my ribs. I use turbinado sugar (probably shouldn't post that, now everyone will have better ribs) and just do them in a grill. 45 minutes bone side down, 30 minutes bone side up, and then wrap them in foil until done (about 1 hr 30 minutes).

    With tape and plastic straps on there, in no time the transformer will fly off in an unintened direction and screw up something other than what you were trying to screw up. If you want to use tape to attach the transformer, use the tape to attach it to the nearest set of balls so that it isn't swung with much force.
