Does it make sense to deliver new clarinets to stores with the cork fittings so large that no amount of cork grease will make for a safe assembly. This is the 2nd new Yamaha I've tried where I felt that the cork should have been sanded down. It took me several attempts using increased quantities of grease and slow assembly techniques to get the horn together. Now, I'm very careful but couldn't the tenons crack if one were to use less caution? I have new corks on my old clarinet and I sanded them down quite a bit. Six months later everything is still tighter than I prefer. Imagine if I had left the cork the way it came from the shop. Imagine how much extra force I would have subjected that instrument to.

Its usually not the cork, but the wood.
This is far too common these days, I carry sand paper with me while teaching at the schools.
Take it to a tech and have it corrected - yes, continuing to force the joints together can result in cracks - I've seen several students crack new R-13's this way.

Many new clarinet will "expand" at the joints, especially the top joint during the warm humid weather. If you don't want to do it yourself take it to a tech. It's usually the wood at the bottom of the cork next to the body of the clarinet but sometimes at the very tip of the joint as well. It's an easy fix with a thin piece of sand paper and someone holding and turning the joint as you sand but a tech may be the best best for you. ESP eddiesclarinet.com

It's also amazing the tuning differences, how assorted notes change. Often different barrels can help the notes when the seasons change.

So the wood of new clarinets expands after the date of manufacture, even before playing? I consider it very risky to ask a person to try to assemble a clarinet for the first time with this degree of resistance. Perhaps a tech should sand down the corks before allowing anyone to test a new instrument. These are delicate things and should certainly be treated with gentle hands when they are so young and tender!

I use my bullet reloading wax. Imperial reloading wax. It was designed for heavy pressure and good adhesion to re-size brass back to smaller than original specs. I found it superior to using any other kind of wax or lube.

Bullet reloading wax. But guns are made of metal and perhaps we have to be careful putting that anywhere near wood. Is this safe?

Ah.. yes... guns are made of metal. But, this is not gun grease for firearms, but rather it is Imperial Sizing wax (key word here is wax). It is not meant to put onto any firearm, and in fact, because it can create such a slick surface metal to metal, you need to wipe it off the resized brass cases after you have resized them. When the primer of the bullet ignites the powder in the case, one of the things that happen is that pressure builds nearly instantly and a lot of it. Smokeless powder burns at a fast rate under pressure and does not explode. What happens next is the softer brass material of the fiream bullet now expands against the steel walls of the firearm chamber and because it has no lubricant on it, it adheres to the side of the chamber and aids in both sealing the chambmer from gas leakage, and also helps to keep the brass from exerting too much force against the bolt face of the firearm. In essence, no waxes nor oils should remain on the bullet when it is fired.
When you resize spent brass(fired) it has expanded to the size of the diameter of the fireamrs chamber (where the bullet goes) and needs to be sized smaller. If no lube is used, or the wrong lube, it will gall or stick inside the reszing die due to the pressure exerted during the sizing down of the brass.
Now, the Imperial Sizing Die Wax is made by Redding for preventing the brass from sticking... use sparingly. So I have used it on tight corks and works like a charm! Your mileage may vary aka YMMV, as they say. I would not worry about it around wood or cork.
