gaps between rows

So I did my first few glue ups. I used the seg-easy sled to cut my segments and most of the rings went together the first time. A few I had to fine tune using the half ring method. My problem is with glue joints between rings. I have a drum sander so I ran everything through the drum sander to make sure everything was uniform and all of the tops and bottom of the rings were flat. One vessel did just fine, the other one appeared fine during the glue up. I used a home made segment stomper, and as I was turning it, there are 2 rings that did not glue all the way around and I can see daylight though about 1/5 of the side of the ring. I can't figure out why it happened, or exactly how to proceed. I can try and fill it with shavings and CA like non segmented turners would do, or I am wondering if I can part that ring off on the lathe and try and re flatten it and glue it back on. Other than that, it is a decent looking piece and I hate to throw all that work away.

Rings usually need flattening before glueup. Often a drum sander can be used, or cole jaws and sandpaper glued to a flat board to sand it flat. Either way the ring needs another sanding after being glued onto the previous layer, best and easiest way is with the flat board and sandpaper. Some folks are adept enough to turn it flat with a gouge. I dont trust my skills that much.

"Thank you. I had been flattening them with the drum sander but I didnt know I had to flatten them after gluing each ring. I have done several without doing that without a problem.

- I generally will run the rings through a drum sander (both sides) to get them down to the planned height.
- I will check the ring for flatness by using a steel ruler placed on edge on the ring. Hold the ring and ruler up to a bright light I look for any light coming through. I check the ring with the ruler at 90 degree (gives you two check spots). If not flat I will sand the ring on a sanding platform (sanding paper glued to a flat surface. I use sandpaper for a 18" disc sander).
- You can also glue a ring on, mount the vessel on the lathe. Using a pencil mark the top of the ring. Sand away the marks while the lather is turning at a low speed.

I have glued a ring to the vessel, put the vessel in a press for 15 to 30 minutes, place on lathe and sand the ring, repeat.

Guess I need to find a drum sander, I WAS using a 12 inch board with sandpaper taped to a glue block on the lathe. I had flat rings but they were not even and one side was taller. Also without vacuum it is a dusty mess and me and the shop pays the price.

If after you add a ring to a bowl and it is not running true there is nothing wrong with taking a light cut with your bowl gouge to flatten the ring. Then a very light touch with the sanding board should do the trick.

Just use a drum sander. when you get to the proper thickness leave the sander setting as it is and rotate the ring 90 deg. and run it through the sander 4 times to compensate for your drum not being parallel to the conveyor belt.
