Hi all,
I finally finished restoring the pre Silva-Bet serial S30. It plays great however it buzzes at times. I traced it to that adjustable barrel. Even when the locknut is tight there is some play in the barrel. I have come up with 2 ways to fix it; 1 is to pack the threads and guide pins with grease. The other is to bend the 4 guideposts toward the center slightly to "tighten the fit." I guess we'll see which works the best. This was probably a comon problem.
Best Regards
Mark

I took one apart and discovered that it was packed with a fairly thick grease. I suppose you could take it down to the Jiffy Lube (not a sponsor, yet) and get it filled.
Of course, the other option is to contact Walter Grabner (a sponsor) and have him make a wooden barrel. I am very happy with mine.

Adjustable necks on Conn saxes and, probably, barrels on clarinets can possibly leak even though they seem tight. I've fixed several old Conn altos tuning problems just by sealing the neck. Good luck with your great Silva Bet.

Hi again,
I did a combination; heavy grease (for sealing also) and adjustment of the 4 guide pins. Problem solved. What a great player, in mint condition as well.
Regards
Mark

This particular type of tuning barrell, just like Conn micro tuners, sounds like a curio only. Heavy automotive/diesel engine grease is good. It is often red or pink in colour and looks like gel. Make sure you warm it between your fingers and feed it into the thread so it gels again. The other option is a beeswax/polish.

Mark:
There is a big difference between the Silva Bet barrel and the Conn metal clarinet barrel. The former was made with a fairly large chamber that was filled with grease. Both have threads that need to be oiled. However, I don't think that it is necessary to use a heavy grease on the threads. They are fairly closely machined. The bet barrels are large and heavy. The conn barrels are quite petite. (Oh, and I think that Bettoney lator offered a much smaller adjustible barrel.)
I guess it would be nice to have measured drawings of the various types of metal clarinet barrels. There were many designs. I agree with Mark's use of the phrase 'curio only'. I suspect that these adjustible barrels were like the fins on cars in the late 1950s -- designed to appeal to consumers but without any real benefit.

Jim,
I agree that tuneable barrels now-a-days are for the most part unnecessary. Back then however, there were different pitches going around. A=440 was probably the offical pitch but probably was not universally adopted at the time. The pitch could have varied country to country, even band to band making a tunable barrel a real asset especially durring the transitional period.
Best Regards
Mark
