18H slide on 6H

[Elow]

Can i slap an 18H slide on a 6H bell? I would think so but i would want to know before i buy a cheap one off ebay. Could i possibly make a dual bore .485-.500 if i swap out the top cork barrel assembly and out slide tube? Even better question, should i?

[BGuttman]

Can you? Yes. Preferably the newer ones that are 0.500". That was a way to fix a 6H with a bad slide.

Should you? Only you can tell.

You just love diy projects don't you?

Ever since school let out ive got nothing better to do besides work. Who needs practice anyways

Yes, the .500” and .485” Conns have the same bell/slide tenons and are interchangeable.

I can't think of any horns that are or were .485/.500, and maybe there's a reason for that. Might be interesting, but might also be a waste of time. It seems to me the connection of one of the slide tubes to the end crook will be problematic. I'd consider two closer bores before those two.

What about a getzen 300 slide? Those are compatible right? I might buy one off ebay and play around with swapping inners on the conn slide to make it .485-.500

Perhaps not Conn, but thousands of Olds tenor trombones (Ambassador, Special, Super, Studio, Standard M7, Self-Balancing M7, Military M7) were dual bore 0.485/0.500"

Many of them played pretty well!

Wasn't there also a very rare Bach model that had this size or thereabouts? I believe it had been mentioned here before...

There was also a .485/.500 Martin Handcraft Imperial . Bore size number was 1A.. I had one.

I guess lots of others knew this (I'm often late to the party), but I just learned that the Conn 30H "Burkle" (produced from ~1934 to at least 1949, perhaps as late as 1958) was dual bore, 0.494"/0.507". Conn's answer to the King 2B (0.481"/0.491"). I don't think they were ever terribly popular, but very interesting trombones. The hand slide crook was tapered diameter to accommodate the change in bore:
