Posted: Sun Jan 23, 2011 4:53 am Post subject: Complete overhaul? |
|
|
I play a vintage Schilke. It's 30 years old, the valves still have an excellent (...!) compression and are still tight. The problem is, one of the valves is sticky, since the inside of the valve casings is scratched (because of 30 years of use).
I am trying to decide what to do. I adore the sound of my horn, and I am not really keen on replacing it with a new horn.
Will the overhaul solve the problem? I know that valve overhaul can be problematic. How much does it cost?
Thanx. |

And it's only problematic when done by someone who doesn't know what they are doing.
I suggest contacting Dr. Valve, Steve Winans...he's the best IMO

My vote is for Steve as well. He is the man with valves. No better. _________________ ‘20 Schilke Xa1 Cornet

Not only is he the man with valves... he's an ex-Schilke employee, who can bring your valves right back into stock tolerances. _________________ Bb- Stomvi Mambo

Thanx, but I'll have to find someone here in Europe.
How's this problem fixed? I'm not sure if the valves need to be replated.
I'd like to do a complete overhaul with silverplating and all that. |

Typically, the valve cylinders will be honed until they are round and straight. The the pistons will be plated until they're too large for the cylinders, then turned down / lapped for the desired fit. _________________ Richard Ashmore

I'd contact Schilke and see what they would charge for the work you want done. I'd also contact Dr. Valve and a couple of other well respected techs here and in Europe and get similar estimates. It may well be that shipping is a good option. I've never used Dr. Valve, but many techs end up sending the horn to Anderson's and getting the valves done there initially and then fine tuning them in house.
But I'd start with Schilke as a base line option. _________________ Conn 6B

Initially, I was thinking about sending it to Schilke to have all the work done. But, when I started to look into the paperwork needed to have it returned without paying customs' taxes and fees as if it were new, and decided to do things locally.
Thanx for all the info |

Schilke has a good dealer network in Europe. Why not ask for a recommendation from Schilke for a competent repair shop. |

If you are in Poland, see who worked on Tomasz Stanko's Schilke. I'm sort of kidding... sort of not. His horn was from the 60s and he just switched to a Monette. Somebody had to keep it running smooth. _________________ Conn 6B

Last time I spoke to Schilke (2008, I think) they offered a great price on a complete overhaul of Schilke horns. I believe the price was $400 at the time, and included everything needed to bring the horn to new. Valve rebuild, new parts, whatever. Their reasoning was they want every Schilke out in the wild to be in great shape. If I had a Schilke needing work, I wouldn't send it anywhere else, even if I were overseas. _________________ 6340S, Connstellation 36B, 38B, 38A, and 28A, Couesnon flugel, Blackburn C, Kanstul/Besson 920 picc, and a HUGE pile of Messina Covers gig bags |

It might just need a really good cleaning a mild lapping if the compression is still good a mild lapping is not going to harm it. I use .5 micron diamond paste that is between 5000-8000 grit depending on which of the 4 media grading policies you follow. I would use a benc motor or a cordless drill and in 30 seconds of less nice clean smooth bores. I would clean before and after the lapping. 30 years is a long time so I would use Naptha first on the inside of the bores followed by Castrol Super Clean. brush out the bores before and after the lapping. Same thing for the pistons I would clean them before and after the lapping.
Ferree's sells a 1000 grit lapping compound specifically for use with their bench motor to lapp pistons in under 60 seconds. I have used it and it works great as well and is also non-embedding.
The reason for the cleaning first is to prevent any old material that is oxidized from being pushed into the material.
If this is too aggressive for you then consider picking up some white toothpaste like Ultra Bright or a whitening polishing toothpaste. 5 minutes of toothpaste lapping is as mild as it get's and will really clean things up with out removing much. Think about it if it was too abrasive you would damage the ultra then enamel layer on your teeth. I guarantee you monel pistons are tougher then the enamel on your teeth and thicker as well! _________________ The only easy day was yesterday! |
