Posted: Sun Nov 22, 2020 5:15 pm Post subject: 3rd Slide slow down and recovery? |
|
|
I am in the habit of oiling valves and slides at the beginning of every session. About 20 minutes into my practice, the 3rd slide on my Benge seemed to snag and remained sluggish thru the rest of use. I switched horns, finished my practice session then inspected the problematic slide. Nothing visible. I cleaned the slide and receiver top and bottom, male and female legs using a Brass Saver snake and warm water, applied Spacefiller TS reinserted and placed a few drops of Spacefiller Ultimate II, my usual mix. The slide functioned somewhat better, but not near as well as usual.
After many more inspections, cleaning and reapplication of lubrication and trial, the slide remained sluggish to the point that I finally took it to a local repair tech. The tech inspected, buffed, and tested several times finding nothing that could cause a problem, but slight improvement. Not wanting to remove more metal, the horn was returned to me. Not happy with the results, I repeated all of my earlier steps over the next several weeks with no improvement.
Then, I tried a different combination of lube, Spacefiller TS and Denis Wick with PTFE on a whim. Instant gratification! The slide performs extremely well, maybe better than ever! I will probably never know what the problem was, but it is fixed. Thank you Dennis Wick Valve Oil, my new slide lube, at least on that horn.
Anyone ever experience anything like this?

Not as extreme as you descrive it here, but the trigger valve on my Olds tended to 'get stuck' when extending too far, thus disallowing the spring to automatically retract it. After a good clean and some slide grease, it was simply sluggish and hard to move. And then I applied a drop of valve oil...it's as smooth as the valves themselves now. Grease + oil seemed to do the trick. |

Hi, Maybe one of the legs of the slide got bumped out of alignment? _________________ FA LA DO (Ab: V/ii) MUCS, USN (Ret.)

My thought as well. Did Tech check alignment? Slides should drop freely individually and assembled with valve removed. Any more work needed, I can put video of the precess up on FB. I performed this many times on new horns at the Schilke shop. |

Thank you for your responses!
The alignment issue was presented to me by the guy that took my repair into the shop. The tech ruled that out pretty much early on. The thing that strikes me as interesting is that the slide did not work properly with my usual, previously working combo, Spacefiller TS and Spacefiller Ultimate II and immediately after applying the Dennis Wick oil, the slide began working much better. After cleaning and applying the Spacefiller TS and the Dennis Wick, it worked as well or better than before the problem began. Could it be the PTFE? Baffled but happy to be playing my decades long favourite horn again after a simple and not too costly solution.

I have experienced things like this, but it's usually due to tiny bits of debris, sometimes almost naked to my eye, slipping into the area in question over time. Often, I know it's there, because there's no other logical explanation.
One thing I'm learning about using lapping compound (Ferree's): It likes to hide and then dislodge when you least expect it. I now use gentle nylon bottle brushes (from Amazon), Dawn dishwashing liquid, and with vigorous pumping action and lots of very warm running water. Then I use 99.9% isopropyl alcohol (just bought four big bottles from Amazon for ~$35) on lint-free cloths (or paper towels) and swab out inner legs (using basic cleaning rod) and repeat all of this process until no sign of lapping compound is on the cloth. I spent lots of time doing this today on a couple of horns. Then I heard from a brass tech about another product, Cold Cleaner, from Ferree's that I'll be checking out. (Strong warning label, btw.)

Question:
Is the Denis Wick valve oil with PTFE odor free? Just curious. |

There is a distinctive odor to the Dennis Wick with PTFE. It is not overbearing, but definitely noticeable when applying. Since I have only applied it to the 3rd Valve Slide on the one horn only, I've not been aware of any odor while playing. I currently see no need to use it on any of my other horns. I will continue to use my favourite Spacefiller Ultimate II on everything else as long as it is available. It's been difficult to purchase the Spacefiller from my my usual sources which is why I bought the Denis Wick in the first place. ACB has been able to supply my Spacefiller needs most recently.
Bottom line: The Denis Wick serves a purpose in my need, so I plan to use it as necessary!

Funny, I never saw the lubing of a third slide as a fundamental. |

I had a similar 3rd slide sluggish operation. Cleaning (at home) several times did not resolve this issue. I was successful using pure lanolin and a drop of Hetman #3 valve oil. After application and use for a day or two, the slide started operating better than when I first received the horn. Now I can go for days, maybe a week, without needing any additional lubrication.
As mentioned in an earlier response, I attribute the difference to loosening some debris or breaking down a film causing the sluggish slide. This was on my LeBlanc with nickel plated slides.
