Back To Basics-G88 Mouth Piece Puller
Nothing to lose. No 1/2 washers to find.
No bent finishing nails. No die cast parts.
Below are pictures of this great tool used on many different applications
First, loosen it up by backing off T-handle.

Most people position the G88 in their weaker hand to hold everything securely, and then turn the T-handle with their stronger hand. All the while holding everything secure while tightening. Don't let the jaws slide over the receiver, hold them tight.
Here shown above on a trombone slide (12H & Bach), and below on a tuba. Always use this grip!
Be sure you get the jaws planted firmly on the mouthpiece stem, so that you 'push' the receiver.
It helps to lay the instrument on a bench or table. Otherwise it can be a two man job.
