Re: [Harp-L] slider troubles

Actually, any slide spring will ride up if not anchored.

He's  right about the safety pin, they make better springs than springs do.... This is the point where you need to tell us what kind of chromatic it is. If it's a Seydel, there is another possibility the spring may not be anchored correctly.  The Seydel springs are short, that, in theory makes em fast, but if they aren't anchored upon reassembly you can have that problem. They can ride up and you get the scratching.

> What spring do I prefer, you ask? (insert sound of crickets) A little something I invented years ago and call the Elk River compound spring.  It's two external springs in tandem, one short, one long. As you push the slide in, you engage the long spring only, then as you push, you engage the short, stiffer spring. So when the spring is set up, at first the push is light and builds as you go and you reach maximum resistance at the end of the push. As the slide returns, the short spring gives it a heave at the beginning then the spring slows down as it comes out. I was inspired by the bow design of the Penabscot Indians.

>> Buono mattina Cal. Pins from different manufacturers will be different torque strengths. High quality pins from the quilt shop (my wife is into that), seem to work. And they can be tensioned to various 'slide throw' strengths just like a regular spring. I'm thinking you like a heavy strength spring. The pins are lower tension and necessitate a constantly clean slide assembly. Sorry I couldn't help. Dave's suggestions are solid. You may also want to check for a 'burn' on the parts. This is where plating has been rubbed through and causes a dull porous non shiny area.

THAT right there will cause a dull area for ONE HALF of the distance that the slide travels. It will look dull. Also, check along the slide itself. If there are dull spots, you have 'drag' Drag will eventually cause 'burn' if not rubbed out. And oiled until it runs smoothly.
