    Making a rolling nut...steel or aluminum there I'm not sure, but certainly good examples of some old school metal working. Enjoy. santa

    Geezer here: I watched the video on making a metal roller-nut. Boy does it take me back to my early days. But seriously, I have two recommendations. The metal in the video appears to be an aluminum alloy. Aluminum is surprisingly hard to work... it's soft but sorta sticky. It will make a fast, strong lock, but watch out for nasty aluminum-oxide buildup inside the nut-socket, which will spread all over your track.
    Second, if you cut your sear-notch all the way across the bottom of the nut, you'll get a lot of oscillation if you let the nut run more or less free in the socket. you'll have to mount the nut on an axle, which eventually turns up various problems. That is why I recommend using a plug-type sear and set the end in a narrow pocket. You get a smoother-running roller without much more effort. Of course it you're cutting them out of heavy metal bar-stock, the step sear would be easier. Geezer..

    That's definitely aluminium... don't think I've ever used a chisel on steel.

    I don't know if you guy's have seen the aluminium brazing rod you can get these days. I got some to repair cooling fins on an old cylinder head for a restoration project.



    There are other kinds. Alumiweld, alumibond 3000... and some others.
    Check it out.
