2  Horns, Gear, and Equipment / Accessories / Re: Stearn's law of leadpipes on: Sep 05, 2017, 07:36AM
Chris, I am going to disagree about how the front of the horn is more important than the back.  I find that most players have a point in the horn that is the #1 thing that makes the horn work for them...maybe the mpc, the leadpipe, slide crook (shape and bore size), neckpipe and valves, tuning slide, bell throat and bell flare.  I think the players input matches the reflection at those points and that returns to the players the information they need.

Many are very mouthpiece sensitive...but the rest is just a megaphone.  I think leadpipes are confusing because many people expect that to fix...everything.  When it doesn't the seach for the holy grail continues while the really wanted a different crook...or something.

Except for the PDQ Bach types, no one plays just a leadpipe.  The trombone is either a complex system that requires fine tuning, or a compact chromatic funnel. If you have messed with 20 leadpipes and not found the winner, it's probably something else.

Snide answer: Learn to hold theh thing so you don't need those crutches.

Less snide answer: Get a Holton TR-150, older King 4B-F, or Olds Opera so you have the brace "built in" (you hold it around the bell brace).

Anything else you do will change the response to some extent.  Some things more than others.  If you need the brace, be prepared to deal with the change of response.

Equally snide response...moving the bell brace also affects response and possible wrapping your hand around the bell brace may dampen vibrations also.

My advise as always, fit the horn to your hand, then worry about crutches.

See your tech.  He should make the lever fit YOUR hand.

I suggest a chardonay or Rheisling...darker wine leave a stain on the cork.

I found one .02" per 1/2 inch...made a tapered die to go in my expander...

Does anyone have a Edwards/Getzen bass trombone tuning slide and some calipers laying around?  I need to measure the taper...inside diameter at the very and and again 1/2 inside.

I'm making a tool to expand them to fit properly :D

Thx

Steam might become an issue (over 212), but hot water should not affect the metal.

Talk to your retailer.
8  Horns, Gear, and Equipment / Repairs, Modifications and Maintenance / Re: How to lube my 2nd valve? on: Jul 08, 2017, 07:23AM
(In my best Dennis Hopper/Christopher Walken voice): Just what are you saying here John?

That taking a valve apart isn't anything to be afraid of.  I spent the week following ITF at the Porkorny seminar.  One theme that reoccured was that many players had the chops and skills to play something difficult but overthought/analyzed until they couldn't.  I see the same thing here, a simple 200 year old mechanical device that is serviceable with a flathead screwdriver and a small mallet....but we'd rather trust it to professionals or find silly end arounds.

Normally, I wouldn't think that taking apart the rotor would be a normal part of routine lubrication. It's not designed to come apart as easily as an axial flow valve, and the tolerances are usually tighter. I don't think I've ever pulled apart a rotor.

Anyway, pull out the entire D crook, and oil it that way. You could take off the tuning slide from the crook, but that would make it take even longer.
I would disassemble the rotor, clean, dry lube and reassemble.  I showed a little girl how to do it yesterday, no problem...I just asked her if she was smarter than a horn player :D

They are just as easy as a an axial and are a looser tolerance for the most part, the big difference is the press fit rear cap.
10  Teaching & Learning / Pedagogy / Took a lesson on: Jul 03, 2017, 06:39AM
For the first time in many years I took a lesson.  Maybe it was being cowardly not wanting to hear what someone had to say, maybe I thought I knew what they'd say so why bother...but I had the opportunity to meet Doug Elliot at the ITF and thought "this is a different approach to what I know, give it a try!".

We met, Doug had me play a few notes (nothing brilliant fell out of the bell...), and then started showing me quite a few things.  Some I was TRYING to do but wasn't able to, others I didn't even have on the radar.  And honestly, I was uncomfortable, not sounding good, not able to make my face comply with what I thought I was doing.  Doug was calm and polite, never made me feel stupid (I did that all myself).  That evening things felt very out of sorts.

The next morning I played in Boneswest and things clicked...sometimes.  When I was able to get the new ideas in my head, fine, but learning a new habit isn't easy...so 75% I felt very good, 20% was the old me, 5% was shifting between the two.  Later that day I played in another group, more like 50/50.

That showed me that what I got from Doug worked and it's just going to take time to internalize it...and I need to work on it at home more.

Thanks Doug!

To be fair, Redlands knows about the heat and the AC is going in every building, so it's just the 5 minutes between venues that will be warm...see you all there!

I'll be there for who whole dealio, I know John Lowe will be there with a BUNCH of Olds trombones in the display area.

I pretty excited first one, probably the only I'll get to on the west coast.

If we got together...what time would work?
13  Horns, Gear, and Equipment / Repairs, Modifications and Maintenance / Re: Alignment Questions on: Jun 04, 2017, 06:14PM
With the added info that you have a Rath...I assume lightweight? The lighter the slide, the more imperfections show themselves.  Some are just...fussy, no way around it.  Give superslick a shot before resorting to Silicone lubes, it doesn't last as long as Trombonetine, but a bit thinner and may be more compatible.
14  Horns, Gear, and Equipment / Repairs, Modifications and Maintenance / Re: Alignment Questions on: Jun 04, 2017, 06:46AM
Most brand new tubes have a little bow in them.  I straighten them and try to leave them for a few days to see if they'll spring back.  Some tubes have a very strong memory, while others are more pliable.  Damage causes a much higher memory in a very small area...

With good care and good slide technique there's no reason for a slide to get out of shape.  I've found that when I attempt to play something out of my ability, I manhandle the slide and throw it out.  And being honest, there's always the occaisional bump going into the case, a tight space onstage or pit, an exuberant fan or music stand...it's just hard to keep a slide perfectly safe.

My Clients make my slide better.  I can let my slide go for quite a while, but when I get a clients slide good, then pick my horn up...OK, time to investigate.  I'm more concerned about playing and don't let small issues bother me, but they do add up.

FWIW, I consider alignment whether the slide is parallel and on the same plane...bows/oval tubes etc need to fixed before alignment, but alignment should not change once properly set-up.  Sorry, semantics.

Don't let worrying about your slide interfer with your enjoyment of playing.
15  Horns, Gear, and Equipment / Instruments / Re: Conn 6H Artist Model - 1990 - not marked anywhere as 6H? on: Jun 01, 2017, 05:57AM
In the early '90s things were weird at Conn, bought by King, attempts at combining manufacturing, curved bell braces on 88H's etc.  A friend had a "mystery horn", a Conn 8" bell .525" bore...no markings except Conn Artist on the bell.  Obviously a take on the 78H but I'd guess it's hard to market something without a name...

If the tech cant't see the difference between a Stainless and silverplated mouthpiece, run...
17  Horns, Gear, and Equipment / Repairs, Modifications and Maintenance / Re: Elkhart 88h inner slides specs on: May 18, 2017, 07:35AM
A few years ago King went to a looser fit on their stockings...a bit too much IMO.  Then Bach followed suit.  I know after complaints from techs, Bach went back to close to original specs. 

The compression is good on the Conn tubes.

When I rebuild an entire slide, the new outer tubes will also be shorter.  Very few people ask for springs in the cork barrels and pitch in general is higher than in 1955 when they designed the original 88H, so not an issue.
18  Horns, Gear, and Equipment / Repairs, Modifications and Maintenance / Re: Elkhart 88h inner slides specs on: May 16, 2017, 06:48AM
Conn still makes 8/88H tubes...they are a hair smaller in diameter, but the shape of the stocking is much improved over the "square" Elkhart design.
19  Horns, Gear, and Equipment / Repairs, Modifications and Maintenance / Re: Edwards Bass Bone Miniballs on: May 07, 2017, 06:29AM
...are your linkages connected correctly?
The miniball arms need to be connected correctly...
There is a slight bend the the miniball arm that should rotate in the direction the valve moves. If installed backwards it will not move correctly  :cry:

Sam

Bends in the actuating arm are typically to get over the valve spindle/stop arm.  If the attachment point is past the end of the stop arm screw the it is unnecessary.

"This is why I don't prefer minibals.."

Are we talking "actual", German made Minibals, or copies as used by some manufacturers? There is a difference. I wouldn't use anything "other" than genuine Minibals.

M

Edwards, Bach, Conn, some tubas...Never really saw a name on them, but I don't order them either.
