Another successful conversion!

I had to replace both the inner slides on my 4B slide, and I figured it was a perfect time to convert it to screw-in leadpipes. Thanks to Instrument Innovations for a truly excellent bi-threaded adapter that soldered on the mouthpiece receiver. I currently Have a Shires yellow brass 1 in there and the horn really punches.

I’m only a hobbyist and not a pro-repair tech, but I think my work is getting pretty good!

Looks pretty good!

You will probably need to push in your tuning slide quite a bit to compensate for the added length.

Just a bit. I cut it down just a bit before soldering on the adapter so it only added about 1/8” to the horn.

Good thinking!

Looks like you removed the index finger ring. Maybe that was needed to make room for the new receiver. I approve....I always hated those rings.

If you can find a leadpipe that works well for you, the changes you made should considerably improve that horn. The standard two-piece receiver/leadpipe on a King 4B is ridiculously small compared to most .547 stock leadpipes. I can’t remember the exact measurement, but I think it is about 25 -35 thousandths of an inch more narrow than most other “stock” leadpipes.

It was actually missing when I got the slide. But it would have been removed anyways, I hate them.

I’ve tried a shires 1 and a shires 2 large tenor pipe, and the 1 seems to suit it very well. The 2 was a bit muddy for my liking.

The Shires 1.5 is said to be the most "standard" of the Shires leadpipes. Many people think it is the closest Shires leadpipe to the standard Bach 42.
