What's the best way to get it out initially if it's stuck beyond hand pulling?
Vaseline DOES NOT mix with synthetic oils - I have had Amado water keys just a little blocked with little dollops of gooey stuff that seem to be vaseline and Ultra Pure - yes, maybe I was a little liberal with the vasso (I use spray vaseline used to protect outboard motors). I have switched to Ultra Pure Slide Grease and Ultra Pure Oil.
tie some larger sized rope / cord around the tube, have someone hold the instrument with piston depressed and then give the cord a quick yank, very few times it remains stuck after this
I'll "fifth" this statement.
I've used vaseline on the brass instruments at school for a long time with no ill effect.
I have noticed, however, that if you grease all of your slides with vaseline, the slides tend to pick up more dirt.
BTW, I grease my own slides with anhydrous lanolin. Great stuff.
Clean your horn more often and use Hetmans #9. I wouldn't wiggle too much as over time this can distort the slide and it will vibrate and "hum" on lower notes. If it is a mechanical problem, take it to a excellent tech. I took my Severinsen to a "good" tech and eventually the "hum" returned. I was told the metal developed memory and returned to it's damaged state! Wish my horn could remember all the tough runs! I would not recommend vaseline because of the previously mentioned dirt attracting qualities. If it is stuck, I would use a t-shirt and twist it tight so the slide doesn't go flying through the air upon release.
Exactly. The 3 Ds - Dirt, Damage or Distortion. Follow simso's advice as far as diagnosis is concerned, but take it to a competent person for any adjustment.
The others will PAN this idea but I guarantee it will work. Shy of any slide bending or malformation (which you've mentioned hasn't happened).
1. Remove valve.
2. Place under flowing cold water from the kitchen tap.
3. With water running at mild flow run 600 grit sandpaper up and down the valve. Slowly rotate the valve in the water flow as you do this. the motion must be up and down though. No spinning of valve. That could make matters worse.
4. Dry valve, lubricate with oil and test.
5. Repeat 1 - 4 above as needed.
All three valves can be treated this way. I do mine every six months to a year.
Thanks for that. I'll give it a try!
I'm not sure you know that much about all that technical stuff, Ted. How can we trust you?
He hasn't got a problem with the valve. The problem is with the slide.
