B&S PT6 modifications

Here's the original layout. The client was having issues getting over the top of the first branch to reach the first slide. The other issue was a stuffy low end with the 5th valve. The end result was a 90 degree rotation of the 5th valve with a new open circuit. Also the leadpipe was re-bent and made removable lifting it off the bell, to a more open position to enter the top knuckle.

Fill and re bend the leadpipe

Braces all made and modifications to the 5th knuckles made, now it ready to start soldering together

All finished up and ready to go.
