Hand-Sharpened Drill Bit
I've previously posted sharpening a twist drill by hand.
th-cam.com/video/wStrlkuwMYc/w-d-xo.html
I do this routinely because it is quick and easy. Here's a video of using a hand sharpened 1/2" twist drill to drill through some 3/8" steel plate.
The drill isn't sharpened precisely, so each of the two curls are different size however it works and is efficient. It takes about two to three minutes to sharpen a drill depending on how dull it is. A broken drill will take several minutes and may need to be heat treated.

    If you put a piece of perspex on the outside of the glass, the glass would probably still have broken but stayed in place and allowed you to show a final result. And use normal thick glass ie 6mm or 8mm , not tempered glass that shatters into a million bits

      Thanks! Nice idea. not sure whether the plastic would bubble and obscure the view before the glass broke but it is certainly worth a try. Plain glass broke quickly for me, just as soon as the molten metal touched it. Most of my glass was from old halogen work lights.

    • @andrewmartin4258

      Styrofoam. In my case it is the pink foam board I use for lost foam casting as well. Not only does it allow a short pause before metal begins flowing down the sprue to insure there is a stable liquid level in the pouring cup, it flushes air from the mold with the vaporized foam. It think the foam also reacts with oxygen when it is hot thereby also reducing the potential for aluminum contact with oxygen. Thanks for commenting.

No air pockets. And the little "plug/styrofoam" allows preliminary filling of the casting cavity, absorbing oxygen as it burns. It's fabulous, magical! And nature adds a skin around the liquid, a skin that you have to learn not to tear. No book explains this! It's one of my best foundry lessons!

      Thanks for your kind comments! I've been trying to learn and improve my castings. Using the glass flask with video has helped me see where what I'm doing can be improved. This was basically to compare a curved sprue with what people normally do. The curved sprue avoids mixing with air and the foam plug pushes a non-oxygen contained slug of vapor in front of the metal front. Liquid aluminum is very susceptible to oxygen.

The attic spaces stay moderate temperature. Disadvantages are cost, you really can't do it yourself, and if you develop a roof leak lumber may rot before the leak comes through.
