Tricks for gluing rings with large number of segments.
Aug 31st, 2015 at 4:38pm
 
Looking for some advice on what others do to glue up large numbers of segments in a ring before the glue starts setting.  I made a 24 segment ring and just barely got it together and clamped; the glue started to set.  I am using Titebond III which is supposed to have a longer set up time.   I plan on making rings (16 segments) with complimentary, primary, and thin strips which is another 16 pieces for a total of 32 segments to glue together.

I glue 2-3 segments at a time, when they set I then glue 2-3 sections together and so on until I complete a ring.

I also try to get glue sections that are either 1/4 circles or half circles so I can correct the angles if needed.

The other option is to apply the glue without compressing the pieces together until all the segments have glue on them.  Then compress the segments together ensuring that they all still have adequate glue and get the alignment as perfect as possible.  Those that have tried this are saying to themselves "Ya right!"  Besides making a huge mess you'll end up re-cutting your segments over again and then gluing up quarter circles.  It is possible but getting that many pieces together all at once is not worth the chance.  Not to mention that the accent pieces tend to slide around  during this process while the clock is ticking.

I have been using Jerry Bennett's cutting jig so correcting angles is not an issue.   When I glued up my 24 segment ring I used a small hose clamp in the middle to help keep the segments from moving too much.  When inserting thin pieces, they tend to warp when applying glue so I prefer to glue the entire ring at once.  I was wondering if others who have more experience with segmented projects might have suggestions how to glue up numerous segments all at once.

Lay out masking tape of sufficient length to cover the circumference + 4", on a flat surface sticky side up. (Fasten the ends with small pieces of tape sticky side down.) Using a straight edge for alignment, place all the ring segments on the tape with the outer edge down. (Fastened to the tape) Put glue on the inner surfaces of your segments. (I use an acid brush) When you have the glue spread evenly, pick up the ends of the tape and form a ring. (The extra 4"will hold everything in place) Lay the ring flat, put a hose clamp on the ring, and tighten. Clean up the squeeze out and set the ring aside to dry.

That is how I have been doing it.I've done 64 pieces at once.Before I tighten the clamp I press the ring flat to get all pieces even.Also I like to test the ring first in the clamp without glue to make sure all joints are perfect.

I use Titebond II (the regular stuff) and have not had trouble getting rings of up to 32 segments, although I assemble the pieces as I glue them and then put a clamp on it.  As I am making rings to add to a conventional single piece bowl base as an accent I don't know if this process has issues with a fully segmented bowl. I don't know why it should; I think most of the strength is in the face grain glue joint between the ring layers. That joint goes together much quicker - I just put glue on the prepped lip of the bowl and clamp the assembled ring to it.
Link below to an example of what I am talking about in case I am not being clear.

I will try the tape idea that Jim mentioned.  Part of my problem might be that the weather has been very hot and dry (+100 F) and the glue dries quickly.  Thanks for all your feedback.

One issue with the tape you have to watch out for is thin veneers getting spit out when closing the ring to clamp it up.  If t you are quick, vigilant  and have the force with you it will glue up good.  So may the force be with you!  Corny, but what the heck!

I too use Jerry's segeasy system and have had no trouble glueing up to 48 segments at a time using a hose clamp but, and here is the caution, make sure you do it when the weather is not too hot.   Typically I'll use Titebound II or III to give me a little bit more time.   I've even used II extend for the extra time.   Work fast, cool temps and you should be OK.

Be careful not to use the glue below temperatures recommended on the container. It will definitely weaken the joint.
