The only other things I can think of are if the felts are the same diameter as the piston or the center hole is too big they may be contacting the wall of the cylinder and picking up the oil. I have never experienced oily felts on any horn. Regards, Stuart

My first thought is that you are putting too much oil on the valves.
My method is to withdraw each valve half way and apply ONE drop to each when taking the instrument out of its case wether is needs it or not. On a long gig I will oil at a break around every hour,

If one assumes a gap of 5/10,000 of an inch between valve and casing the volume to fill is around 1/100 milliliter,, one drop is approximately 1/30 ml so is ample.

Another thought, when in the case are the instruments sitting vertical or horizontal, ih horizontal oil might be migrating along the spring box to the felts.

Regards, Stuart.

Please tell us more, what is the make and age of your trumpet and are the valves top or bottom sprung? I have some thoughts on this.

Regards, Stuart.

Why not just swap the caps between the 2 instruments, the bottom caps do not matter but if the top caps are of a different thickness the valve alignment will be effected.
If you are adventuress there is a great number of DIY copper plating instructions on youtube,

Thank you Greg for your update on Windworks, I realize it is near 20 years since my lessons with Greg, he had not been teaching long and was still developing his thoughts. I still use his book as a warmup. At 86 I don't think I will be having any more lessons. Regards, Stuart.

@SSmith1226 I had a couple of lessons with Greg some years ago when he first started teaching when he lived here in Melbourne and have his original Mystery to Mastery book. I would have had more lessons but he moved to Queensland some 1000 miles away, There is nothing way out in his teaching although he has his own nomencular for some of the concepts, Regards, Stuart

@barliman2001 Google ebay.com g.mu6 will give link to his store. Regards, Stuart.

Several years ago I purchased a Amati Eb piston valve trumpet from ebay seller g.mu6 and cut it down to F, I have only played it once in Orchestra, no complaints.

I see he has a couple of rotary valve F trumpets for sale.

Regards, Stuart.

@acb The Wiss has been my main horn for three years now, I have used it in the community symphony orchestra, big band and wind symphony, my initial impressions have not c,hanged, it is the best horn I have ever played, I have had no problems blending with a section of Bachs and other makes, I have carefully checked the tuning with an electronic tuner and found a maximum error of +- 6 cents from the even tempered scale over my range (2 1/2 octaves). AT 5500 euro it was not a cheap horn but commensurate with other hand made horns. Regards, Stuart.

I have made several sets of inlays from 1/8" black bakelite sheet, cut octagen shape. glued to end of rod with melted shellac and turned to size in the lathe, rounded top edge and polished, glued into button with Super Glue Regards, Stuart.

Sassenach, ye no ken the pipes. Regards, Stuart.

@barliman2001
Ebay seller Gmu-6 often has F alto rotary valve trumpets, some time ago I bought an Amarti piston valve alto trumpet in Eb from him. takes a standard trumpet shank, cut 150mm out of the loop in the bell tail to bring it up into F, one of these days I will shorten the valve slides to finish the job. Regards, Stuart.

I have only stretched one set of springs, I think it was a Conn 22b that belongs to a friend, the problem was the valves were not returning to the top, stretching fixed this. I have a Courtois French Besson trumpet that came from the factory when they moved out of France, I believe it was a prototype that never went into production. The valve springs were so strong it was painful for my arthritic fingers to press. Searching the stock of 2 repairers did not find suitable. The springs the original were 12mm internal diameter, I thought I might be able to expand a smaller dia one. A set of Yamaha Flugel horn springs were about 10mm id and had a lot of turns, forcing the springs over a 12mm rod and tapping all round with a small hammer until the spring released its hold on the rod gave me a spring of the right length and strength, a 100 gm weight will depress the valve 1/2 way which seems to be common on several of my horns. ( Could someone please tell me how to paragraph a post) Regards, Stuart.

No prices given. but if I have to ask the price I cannot afford it. Regards, Stuart.

From the FAQ on the website saxophones made in China and Taiwan, reasonable assumption trumpets are too.

@trumpetsplus Congratulations Ivan on the new venture. your new website is not recognized by Google, I get taken to Prof.Dr Matthias Bertsch alias Dr Trumpet. Regards, Stuart.

@dr-go WOW!!! great glisses.

Regards, Stuart.

@barliman2001 Curious about the 4th valve loop, my Selmer G the 4th valve only drops a tone to F.

Regards, Stuart.

I get the same message in Australia.

Could not find my old measurements, I have measured 4 Selmers, diameter of inside of bell and distance from bell mouth. Regards, Stuart.
