LT16M slide modification

[Boneaphone]

I have a 1983 LT16M that I would like to have the undersized slide crook replaced with a King 3B crook. There are lots of posts on this forum about this modification. My question is: Is this an exact fit or must slide width adjustments be made? Thanks for any information!

A crook replacement involves removing the existing crook, and undoing both the outer handslide cross brace, and inner cross brace. Then the slide is reassembled with the new crook establishing the width of the slide.

You might want to consider m/k drawing crook too. You can get a larger ID than Bach parts but get a dual radius and optionally in nickel. I have one that’s great.

Matthew is, as usual, right on with his comments. Even if it were to be “the same” width according to the manufacturer(s) it would be best to build the outer slide around the parameters of the replacement crook.

For what its worth, Yamaha also makes a crook that would be a suitable option. 891Z crooks are nickel and have actual ferrules, unlike the King crooks that are brass and have expanded ends where the ferrules would be.

I replaced my personal (Corp Era 16LTM) crook with the Yamaha crook and have been pleased with the result.

Thank you all. I obviously haven't talked to my Tech about this yet.

I had that modification done to 16M I had years ago. I also had the tuning slide crook replaced with a 3B one and the leadpipe pulled (I hate that short 16M leadpipe) and replaced it with a Kanstul H8.That horn blew so free and easy
