    Brilliant Tapping Trick on the lathe or mill

    Many of you will know this trick, but I only learned it recently. I read about it in an article or letter in Model Engineer's Workshop magazine and had to try it. I was sick to death of breaking taps and this is a fantastic way of not breaking taps and getting a perfect thread every time.

    That is a very good idea. The De-Speeder as shown may be difficult to find. But most everyone as an old rechargeable drill. I have collected at least 5 in a box from over the years. All of the ones I have use planetary gears to "de-speed" the little high speed motor and multiply torque for the drill. While it would take a little modification to make one into a tapping tool as show, all the important parts you need are there.

    IIRC the de-speeders were intended so you could use an OG drill for running screws in. Before variable speed reversible drills. I think I have one around here with 2 rings on it. one makes it go forward and the other backs it off.
    I also have a couple tapping heads for the drill press and mill, might work well on the lathe too?

    Thanks hemmjo. They do come up on Ebay quite regularly, at least here in the UK, but I always assumed, maybe wrongly that Rawlplug was a US company. Also, your idea sounds very sound.

    Thanks for explaining. I will add your info to my video's description if that's ok.

    Sure... although that is just my memory. I know I used them for screws before I had the VSR drill.
