vented valves

Postby bloke » Tue Sep 13, 2016 2:58 pm

I just picked up an F tuba like mine (4+2 configuration), but it's a new instrument with thicker metal / larger bell throat /larger bore sizes.

I've been t̶w̶e̶a̶k̶i̶n̶g̶ ←(hate that word :x ) picking over this new tuba and raising it up to "bloke standards". ' quite a few hours to address absolutely everything to make a tuba "not annoying to bloke". :| (I've really been enjoying the nicely-machined rotors and linkage. It's a pleasure to "t̶w̶e̶a̶k̶" things that are so easily "t̶w̶e̶a̶k̶e̶d̶".)

I have also been enjoying the 186-like sound quality of this instrument...not quite as clear and pretty a sound as the "Symphonie Modell", but rounder/bigger and (again) could-easily-pass-for-a-4/4-contrabass-tuba sound.

The very last thing (possibly)...
I had been noticing that "slurring" wasn't particularly easy (compared to my old B&S "Symphonie Modell"). I credited that to "larger bell" and "larger bore sizes"...even (possibly) considered passing this tuba on to someone else.

OK...(duh). I finally realized that none of the rotors were vented. I just vented all of them. slurring now: great

Tweak > twerk.

I digress. If I should go back to an all rotor instrument (I'm finding that I'm more inclined day by day but haven't found the right horn to trade for yet) I will definitely get all the valves vented.

I find that venting - porting - affects feel more on piston valves; rotors not as much, but there is a "bump" sometimes after turning a rotor that's been at rest for some time. On rotary CC horns, at the very least, I like 1 vented, because I cant stand the pressurized "pop" when pulling a slide (I usually manage to move the slide before or after the slide circuit is active). I asked for 1st and 4th vented on a rotary horn I sent to bloke once, and got it back with all valves vented. I didn't complain because the vent holes were executed very well and it played better; whether that was due to venting or not, well, I'll let the tnfj decide :) . I enjoyed that horn immensely after bloke did stuff to it. I still miss it, but life happens.

Anyone here own that Meinl Weston 37 with all valves vented?

My old Miraphone 188 had vented valves -- that tuba was REALLY easy to play and slur. Not sure how much the vented valves contributed to that, but I'm sure it didn't hurt. Out of all the stuff I've owned and sold, I probably miss that horn the most, but it was just the wrong tool, and I have an unfortunately small toolbox. :(

I remember really wanting that horn when you sold it, and as with many horns I want, I couldn't get the money together in time.

Well, it's in your state (yeah, I know, it's huge...). Maybe you will run across it sometime? :tuba:

Perhaps (??) I'm a "weak" player (??), but the little "pop-pop-pop-pop" air changes slightly (...well...) "screw" with me when I'm trying to move smoothly from one pitch to the next. All of my other instruments are vented...

might be right !

...or I could superglue some fishin' weights into the each of the two ports of my existing rotors...

Same with me, but it's more noticeable with low tolerance pistons, not to say it doesn't happen on rotors. Bob Rusk mentioned I had to replate before thinking about venting his prototype F tuba when I talked to him about it at ITEC Indiana, but I had it done anyway, because playing it in tune in an ensemble required a fair bit of trombone playing. Even with the rather high tolerance, the effects of venting were positive. I enjoyed and miss that horn a lot too. Shame Getzen never had a production run of them.

I completely agree regarding vented valves and slurring. I much prefer my valves to be vented. Some horns seem to *need* this while some are not so bad. (Leaky anyway?) I have certainly never noted any sort of ill effects from venting.

Now head on over to Amazon and get your reward for a job well done...

perhaps later. :|

This thread is burned up...' nothing else to say, really, and since it's OK to go off topic,
I have a question for the administrators/monitors, etc...
Oktober is upon us...
Can we initiate a topic in "General Chatter" called "beer girls 2016", or does that need to go in the hidden/invite-only forum?

Got 'em. Love 'em. Don't know how I ever lived without 'em. No, really, articulating and slurring on vented valves is so much easier for me - I highly recommend it.

the guy at miles ahead vented the valves on my 2341 and while i had read that it would make a difference, i was really surprised at how much it changed my horn. maybe it was psychological, maybe not... i think i play better now.

Question: Is there any difference in venting (piston) valves for a compensating horn? I'm thinking there isn't, but want to check in case there's something I'm not seeing about it.

Question: how much would it cost to get valves vented? Say, 5 rotary valves...?

Dillon's website says $50/rotor or $150 for 4.
I'm pretty sure Eric Peterson would give you a quick quote and you won't have to leave Minneapolis.
