    Default Making a Turnscrew

    It's not exactly woodwork, and it's a gunsmith-style turnscrew, but I suggest it's relevant in several ways to things that come up here.

    Yes, if you look around your shed, there are all sorts of bits of metal that can be re-purposed, but you may need to anneal or harden some, which needs a good source of heat.

    Files are good raw material, but too brittle as-is & you need to anneal them for most applications, unless you are turning them into metal srapers. If your heat source isn't up to getting the whole thing hot enough, the tang ends are much softer than the blade part & can be be used as is for small parts. They are just right for small turnscrews. Here's one from the tang end of a small flat file: Small turnscrew.jpg

    An old mower blade was just the right hardness to make this driver for the wide-slotted screws on plane blades: Plane screw driver.jpg

    And old steel circular saws are another excellent source of tough, but workable metal for drivers - these are obviously for split-nuts: Split nut drivers red.jpg

    Cheers,
    IW

    I frequently make them out of scraps of saw steel. This one is for the very narrow slot 1870's Disston nuts.

    Paul,
    one of the things in this video to note is the height of the vice jaws.
    The elbow position while he filed is so important to get a file to work in your favour.
    Here is one of mine.
    Cheers,
    Peter

    Leaf springs from vehicles are another source of high carbon steel, but must be annealed first to work with them. I use the slow combustion heater, which pretty much limits the task to winter time.

    Regards

    Good point Peter. I sometimes forget our range of climates in Oz and the fact that some places in Victoria can have all four seasons in one day . On the positive side you stand a good chance of appealing to the blacksmith in you all year round.

    I have to anticipate what I might need steel wise for the next nine months: I rarely get it right.

    Regards
    Paul
