Topic tags/keywords: segmented turning

Hi folks,

I am making my first voyage into segmented turning, and I have made a wedgie sled and cut the segments for a small bowl that I designed.

My question is about gluing up the rings. I have done 4 of the 8 rings using pipe clamps, which are working terrific. I have one ring, though, which I designed using 1/4” thick walnut. The segments are cut, but I haven’t glued it up yet. My concern is that the pipe clamp is wider than 1/4 inch, so I’d have to use the edge of the pipe clamp to apply pressure, which I worry will distort the segments so that they don’t sit flat.

One thought I had was to use two circular pieces of melamine that will press the segments while they’re glued up like a sandwich, which will be just smaller than the diam of the actual walnut ring. I can clamp them together while gluing up, which then would ensure that the thin walnut pieces stay coplanar with each other.

What have experienced segmented turners done in this situation? Am I making too much of it, and shouldn’t even worry about possible uneven clamping pressure? Thanks for reading and considering.

I made a press for gluing rings together. You could glue the rings together on the lathe.

Here is a tutorial of how I do segmented turnings. For material thinner than 1/2”, I glue it to the material of an adjacent layer before cutting into segments. I have built up many layer laminations of thin material this way.

Thanks folks for the help! Any other ideas or tips are helpful, but this looks like a good start for me.
