King 605F Specs

[Driswood]

What is the bell and bore size on this model?

[BGuttman]

Matt K had one. I think it was 0.485" bore and 7½" bell.

[Burgerbob]

Small. Too small to really be viable, imo. I had one.

[JohnL]

Published specs are 7⅜" bell, .491" bore.

Not sure what the bore through the valve is.

[Finetales]

The rotor isn't much bigger than that, if at all.

My 605F played pretty well, but I think the student grade leadpipe hamstrings the instrument. I bet with a 2B slide or leadpipe they could be pretty great. But yes, they are quite small.

I technically still own my 605F, it has just been sacrificed to a mad science alto trombone project.

Hi Jerry!

The valve on the 605F is rather small also. A couple of years ago, I built a custom small bore bell section with a valve that had tuning slides for G, G-flat, F and E. To match the graduation of bores from the hand slide into the back half of the gooseneck, I was looking for a valve in the .512 to .515 bore range. Someone offered me a King 605F valve with all of the F tubing intact. I can’t remember the exact bore (probably somewhere around .495 or .500), but I remember that the valve was too small for that particular project.
