Bass Valve Weight

Does anyone have a rough idea of how much the different bass valve sets weigh? Was curious how dual hagmanns or tru-bores would compare to an axial set up, or to standard rotors, etc. Thanks!

In my experience, Hagmanns and rotors will be similarly light, trubores and axials similarly heavy.
Who made them always makes a huge difference, of course... valve location, bracing, wrap all make a difference. Even the two sets of independent Trubores (normal and Bollinger) are quite different, I think the Bollinger ones are much heavier.

Yeah, weight distribution vs mass...
Hagmanns are relatively light - for the space they take, there's not much metal inside.

Yes, forgot to mention. My Holton 185 is a bit awkward because so much of the mass is way off to the left and forward. Axial horns are usually pretty good in this regard, IMO.

Balance is more important than absolute weight. Think about why tenor trombones have a counterweight.

That mostly tracks, except I think Bollinger TruBores are the same as standard ones but with less tubing, so they should actually be lighter.
However, the caps of TruBores were changed to be significantly heavier at some point, so if you're comparing an old set of standard ones with a newer set of Bollinger ones, that would be the difference you notice.

The ones I played had a TON of bracing (the wraps were pretty different), I think that made the change.

Interesting. I've never taken a really close look at one.

Though I've never tried them, I've read often that the Kanstul CR valves are really lightweight.

[quote="LeoInFL"]Though I've never tried them, I've read often that the Kanstul CR valves are really lightweight.[/quote] They are. They are not made from a solid piece of brass, so there is a lot of air space inside the valve. Love mine. Sucks that Kanstul doesn't really exist anymore.
