Gap between leadpipe and MP - Then in the case?

Post by whitbey »

I had a big change recently. Caps on my front teeth.

I was not as centered on one of my horns so I put a little pipe tape on the shank. A few trials and I like it better.

So now how do put the MP in case without messing the tape?

Players have been doing this for years. Must be a better way.

1. Don't force it in too hard.
2. Twist gently in the direction of the wrap.

Some guys don't bother and use new tape each time.

Is there a better way? Find a way to increase the diameter of the shank. Figure out how many mils or microns worth of tape you use and either have a sheath or have the shank plated that much. Note that plating over 1 mil (25 microns) is pretty difficult.

If it's one of mine I can make a shank with a little bigger taper. Not a problem.

Just keep the mouthpiece in a protective sleeve or pouch, and put that in the case. The mouthpiece slots that are built into the case are for people who hate their mouthpieces.

I think I will use the tape and that foil until I am sure of the gap then get a new shank from Doug. I should have gotten a larger shank for the bass bone MP I just got. That lead pipe is over size and always need tape.

Thanks!

Be aware that under certain conditions contact between aluminum & brass or aluminum & silver is be a recipe for galvanic corrosion:

Galvanic corrosion is a slow process. The aluminum tape wrapped around the shank has a thin layer of adhesive that will slow the action, and the tape wrapped shank won't stay in the leadpipe for very long.

To guarantee no corrosion, you could use a polymeric tape. I have some Kapton (polyimide) tape that is 1 mil (25 microns) thick that would work well and last almost as long as the aluminum.
