    I know everyone is looking for a new or better way to clamp segmented rings. I ran across this on You Tube this morning.
    The Rasmussen clamp:

    Very interesting. Someone posted about using string either here or Segmented Turners but I can't find the post. I like how he stressed having the end over a joint.

    Seems like it could be a good jig. Wonder how long the strings lasts till it has to be replaced.

    Nylon cord should last a long time. It would be easy enough to have several cords depending on the size of the ring.

    Sometime I am going to build one. It should work for .5+ thick rings. Maybe down to .25. Smaller than that I don't think it will work. A metal hose clamp works well for thinner rings.

    With this jig, I may go to making thicker ring halves then splitting them on the bandsaw for when I want .25 or less thickness.

    Forgot. Bob, thanks for posting the vid.

    Thanks for the post Bob. Made this today and it works exactly as advertised. Only took about 20 minutes. Using paracord it should hold up for quite a long time.
    Cut an 18 segment ring on my, also new, wedgie sled in 5/16" poplar, as a test, and it held together like a champ. Needed to use a weighted piece of plywood on top of the ring to hold it in place as I tightened the clamp. Thicker pieces will probably not need this step.
    Thanks again to you and all the other posters for their help. I'm learning so much here.

    Thanks for posting this! I'm working on 24 segment rings for a bowl right now. Rings are 1/4" thick and this thing works great! I just retie my cord when I dry fit my rings and it works perfect every time!
