Greetings Tubenetters,

I'm considering using a bell from a Yamaha YBB103 for a project, but I fell down a Google rabbit hole and wasn't able to find much info on the dimensions of the bell.

Specifically I need the length of the bell, and the diameter of tenon. I'm assuming the flare is the same as a 621, which according to the internet is 14 3/8" so hopefully someone will correct me if thats wrong.

Help me Tubiwan Kenobi... you're my only hope...

The YBB-103 bell is the same one used on the YFB-621. If you have the dimensions of one you have the dimensions of the other.

Cheers!

I don't have the dimensions of either bell, except for the diameter of the bell flare.

I did try to approximate the dimensions from a picture based on that one measurement.

I could be way off because I made a lot of assumptions like the camera angle etc, but this is what I came up with:
Length ~24"
Tenon ~2.74"
If this is way off my hope is the internet will correct me
