Subj: Re: [kl] loose barrel rings

Daniel I understand what you are saying. Rings serve three purposes. 1: to
prevent the tenon from splitting or cracking when you place the male tenon
into the socket, since this is the weakest part of the instrument. 2: To
prevent the wood from overexpanding due to moisture, weather conditions
3: Aesthetics.
The rings keep the socket in check. By putting paper or whatever to
tighten a ring is improper, since it does not have the same density a the
wood. This can ultimately cause the joint to crack. Gluing is not an
option, you are actually defeating the purpose of the ring, this is only
for aesthetics. Glue is just holding in place, if might fill a small gap,
but as I stated above, glue does not have the same density of the wood. By
shrinking the actual ring with a die and fitting to the tenon, this causes
the wood to compress in that area, thus not allowing the wood to expand to
the point of cracking. Also when the female joint expands(usually more than
the socket, it prevents the socket from cracking or splitting when you
remove the joint or put it together. I've also used a natural oil
treatment(similar formula that the Buffet factory uses) to the joint before
I tighten the ring, especially if the ring is extremely loose. Also
sometimes the factory does not tighten the rings properly.
The price of the ring machine is about $500.00. The actual job cost
between $15.00 - $20.00 per ring.
