Before anyone says anything, I searched the archives and didn't find any threads on adjusting composite barrels, and even if I did I doubt it would be about adjusting a small ring near the bore(read on and you'll understand).
I recently bought a C. Robert Scott barrel for my newer R13. When I put it on the upper joint tenon, it fit nice and tight, but then as I was putting it on it stopped and left about a 2-3mm gap. I ignored it because the barrel seemed to play in tune and sounded good where it was. A few days ago I tried to push it all the way on, and sure enough it did, but it was very tight. Not tight enough to get stuck, but tight enough to make me wary of bending top trill keys when taking it off.
I believe it is getting stuck near the top of the inside of the barrel and at the top of the tenon.
I don't need to adjust the whole inside of the barrel, just the top .5cm closest to the bore. What is the easiest way to evenly adjust it so that it doesn't fit so tight.

It may be tight at the bottom of the tenon, between the cork and the shoulder. I think that is more common.

If you are comfortable doing it, get some sandpaper and just sand the inside with your finger guiding the paper. The great thing about sandpaper is that it takes a little bit of material off at a time, so you can have time to see when to stop and so forth. Sure it takes a good hour or two, but in most cases, it gives you peace of mind, knowing your barrel doesn't get stuck.

C2thew,
I thought about that, but my problem is not the whole inside, just part of it for some reason

This fix is best done on a lathe or with a special socket truing device.
The latter is a single edged reamer with a pilot bearing which trues to the bore. A local tech may have one.

Alseg,
Now that you mention it I know of one very reputable clarinet/oboe tech in my area who has lathes. Wether or not he has the reaming tool to use I do not know, but this barrel isn't special to me as it is not very expensive and I plan to buy a wood barrel sometime in the near future.

...and if the tech properly puts the barrel into the lathe (and its hole is centered well) he may do it with standard equipment, without a pilot and such. Mine shortened a plastic Bundy barrel within three minutes, and I was unable to detect any after-market treatment...

Ryder,
I too own a Scott compostie barrel and have the same problem. It actually works out for me due to tunning issues.

Patrickryan04,
When the barrel is in the position in which it stops at without me forcing it the rest of the way on it plays in tune much like you mentioned. I just want to have the ability to push it in if I go flat ovrall (which on my clarinet is a rarity). If I'm out of tune I'm usually always sharp.
It doesn't bother me much, but like I said i just want to be able to easily push in if needed.

I understand, wish I could offer some advice on the matter.

I had the same problem 2 times on the bottom joint and the bell on 2 Buffet Internationals that I once owned. I couldn't get the bells on and both times, my husband used a caliper and found that the problem was the rim of the wood (not the outside rim but the inside rim) on the bottom joint was slightly bigger than the inside of the bell inside joint and so using a stiff emery board, just slightly sanded around and around until the bell slipped on all the way. I just couldn't figure out what was the problem but when my husband measured it with a caliper, then that's when we found out what the problem was. I have also had the problem where the outside rim was making it hard to assemble the clarinet and I sanded slightly to reduce the rim and it went on easily. If you use sandpaper and take your time, you should be able to fix the problem yourself but I don't know if I would be sanding on an R-13 clarinet if other barrels fit on comfortably. I would be more inclined to adjust the inside of the barrel myself. At any rate, using a caliper, you will be able to see exactly where the problem is.

Bonnie,
I am just going to adjust the barrel. No sense in ruining a perfedtly good tenon.

There seems to be a good deal of inconsitency on the part of Buffet over the cutting of tenon sockets on all parts of the clarinet. A machinist who is good at wood or a repair tech who is fine at adjusting tenon wood to fit correctly should be sought out. A piece of wood that is too large for a fit will end in cracking the bell or the joint in question. Strangely enough I had in the past a R13 clarinet which cracked in the lower joint as a result of this problem. The repair tech could not believe I had a crack in the low e tone hole area from above!!! This crack went through the low e hole from above. Neither could I. I also had this R13 crack in the upper joint later so I was not not a happy camper. As to the repair the tech did a great job in fixing it up...later the clarinet played superbly.

All the sockets on Buffet clarinets are made with a slight taper - does anyone know WHY??
I find them a pain as once the cork hardens slightly it takes a mirror taper shape, as a result as soon as you pull out for tuning the whole assembly becomes wobbly.
I don't know of any other make that has this quirk.
Easing the shape of socket to make it more nearly parallel makes a great improvement in cork life and joint stability.
A proper socket reamer is the real answer but careful scraping with an engineers scraper can give a close approximation.

I have a Robert Scott barrel for my Eb clarinet and have the same problem. It will go on, but definitely sticks just as you are describing. So it's not just your horn!
