Re: [Harp-L] slider troubles

 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.

You could also check to see if the angle of attack into the slide hole is so great that it's pushing up on the parts. 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.
