Gluing the Segmented Rings

Here you can see the walnut spacers to be glued between the maple segments. Be sure to sand any frayed areas of the wood to ensure a clean glue-up.

I use Titebond II to glue the vase.

The rings are now being assembled with the aid metal adjustable pipe clamps. These clamps can be purchased  at Home Depot, Lowes, or at a plumping supply. I like to use these clamps because they cinch the segments up tightly. Again, the clamps are adjustable so you can adjust them to a variety of ring sizes.

One thing of importance:
Be sure that the segments form a tight fight as they form a complete circle. The segments need to fit tightly. I like to make test cuts of the segments on the mitre saw using scrap MDF or plywood. For example if I have a segment ring of 12 pieces...I'll cut 6 segments to form a semi-circle of 180 degrees and lay it flat on my table saw up against the rip fence. This way I can test the accuracy of the mitre cuts. The angles of the mitres will be either open at the top, open at the bottom, or a snug fit. I'm looking for the snug fit before I cut the material to be used on the vase. I use the Wixey digital protractor to align the blade angle on the mitre saw. In this case it was 15 degrees.

Here's a close up of a ring assembly glued and clamped.
