    How to Make Smart Heater

    Great article, but....Sorry my friend, "cutted" is never correct in English. The correct past tense is "cut", ( I have cut the pieces) the present tense is "cutting", (I am cutting the pieces now) and the future tense is "cut" ( I will cut the pieces tomorrow) Hope this helps.

    Before assembly, brush the surfaces with glue ( Elmers. Titebond, Gorilla, etc) and cover it immediately with an already cut to size old shirt, It will last more than a short time.....

    and retired 60 year woodworker and English major...Enjoyed your 'ible, except for the misuse of a term...Sank is the past tense of the word sink. The ship sank last week. Sunk is the past participle for of the word sink.The submarine has sunk beforeThe past participle always requires the helping verb "has"or "been" therefore, one needed to countersink the holesone is countersinking the holes, but when completed, one wouldhave countersunk the holesCountersank would need a helping verb which would change themeaning of the termcounter-has-sank… but your counter... didn’t sink... it was sunken. ;-)

    It is an anti kickback device In this case not being used....

    How to Make a Scratch Awl

    "Hot dipped" means the nails are rust proof. Hot dipping nails in Molten Zinc is acknowledged by most authorities as the best way to apply a heavy uniform Zinc coating to nails. In this process, the nails are completely immersed into a vat of molten zinc, similar to "French Frying" potatoes. This not only gives an outer coating of pure zinc, but also provides a tenacious inner coating of zinc-steel alloy. It prevents stains in wood from steel oxidation (rust).Grinding, or sanding to a point, removes the protection in that area.

    Your first photo looks like you attached the hook directly to the sheetrock, which is notorious for poor holding qualities. Hopefully, you located the studs in the wall and screwed the board to those. They're usually 16 " on centers the screw shown doesn't seem to be of sufficient length to attach the board to the studs, considering the board is 3/4 " and the usual sheetrock thickness is 1/2". To get a solid attachment I'd recommend using a screw that is at least the thickness of the board,+ the sheetrock, and add another 1/2 inch, to that so that penetration into the stud is proper. A weight bearing object, even if only a lightweight item, needs to be firmly attached to the stud behind the sheetrock, to avoid a repeat of what happened to the first hook.

    The water used in polishing, is to prevent heat buildup in the wax, and causing it to smear. water lubricates the cloth and helps polish the wax. Ask any GI that has spit shined his boots...!

    Concrete Octagonal Driveway Pavers

    Use some (old) motor oil brushed on the molds, and the concrete won't stick .been doing that now for 50 odd years. Look up the term "slump" to get the proper consistency of the concrete mix... and Webmasters: go back to black text .This grey on white is the worst fad you guy's have ever come up with! Very difficult to read!!

    Router Planer

    I did this a few years ago, with a full sized "Ryobi" tm. router. But I used an 18" x 18" piece of 3/4 inch melamine for the base.( smooth, stiff, and slippery) When not being used as a "planer" I turn it upside down and mount it in a 5 gal. bucket filled with a few inches of sand for stability, and a plywood ring the size of the bucket interior, mounted to the router side of the melamine, to keep it from sliding around. I added a clamp on fence, and turned it into a portable router table. Viola ! 3 tools in one.

    Like your " 'ible" !! However...When replacing the MOSFET, with a 10 K pot, (brightness control?) what do you do with the pin 5 connection of the shift register? Does it get grounded ? Ommited? Left in Limbo??? Very unclear to me... and not on schematic. Thx.

    How To Copper Electroform A Ring

    "PATIENTS" = are clients of a doctor.Having "PATIENCE" = The art of taking ones time, and not rushing thru an endeavor.Their usage is often confused. When I was in High School science class,(*way back in 1492, when Columbus was setting sail ) I used Copper sulphate in a saturated solution for electroplating a "Zippo" Lighter case.**GracieM9... Try sealing with clear nail polish. (It's lacquer based.)**Lisa246... keep the part of the shell you do not want plated, from coming in contact with the plating solution. Thickly coat, the areas you don't want plated with some rubber cement. Peel it off when done. (* yep I'm an old codger!) **Hope this helps you!

  • Converting a Cabin Light to Led and Voltmeter!

    Sorry my friend, that voltmeter looks like it is just about useless... or your car's battery is dead..On the workbench it shows 47%. Don't know what that's powered by, and it's not important. Installed, the voltmeter shows 57%. 57% of what?....the battery voltage? the charging voltage??? They are different.If your BATTERY is showing a 57% charge it has only got a workable voltage of 6.84 volts . A 12 volt battery, is usually considered dead at 8 volts or lessIf it is 57% of the CHARGING VOLTAGE, of say 14 volts (the average charge), THEN YOUR CHARGING VOLTAGE IS is only 8 VOLTS. [Oy Vey! ..the math!]You are not going to be charging a 12 volt car battery, with ONLY 8 volts.

[Oy Vey! ..the math!]You are not going to be charging a 12 volt car battery, with ONLY 8 volts. Now I have been working on my own vehicles, for better than 60 years and was an electronic technician before I retired. My OEM dashboard voltmeter was acting very strange, and showing a reading of 20+VOLTS!!! I knew this had to be some glitch with the car's computer, so I bought a direct reading LED voltmeter. It proved me correct. The OEM gauge read 20+ volts while the LED voltmeter hooked up (outside the computer circuit,) still showed my normal charging voltage of 14.5 volts. (AT 20 VOLTS I WOULD HAVE BEEN BURNING OUT 12 volt LIGHT BULBS LEFT AND RIGHT!)There's plenty of them on eBay (Search led digital voltmeter) for about a dollar. or so... you can get them in a number of colors. These will read the exact battery voltage when the key is off, and the charging voltage with the engine running. and there will be no math needed, to interpret their readings. Don't worry about draining the battery by leaving it lit. It's tiny current draw would take quite some time to drain the battery. Mine has been running now for almost 6 months, and it hasn't dropped 1/10th of a volt. Great 'ible otherwise.
