[Harp-L] Saxony spring

[Sheltraw]

Hi Joe 

Yes. I was thinking about the angle the spring arm makes with the plane of the slider but I am not too concerned about wear on the slider hole. I am more concerned about the increase in slider friction that this angle may exacerbate. This concern arises from an observation I made when trying to go springless a year or two ago (Wim Dijkgraff does this ). Without the spring the slider friction is greatly reduced. So I was wondering if others had played with bending the spring near the hole as a way of diminishing the torque that brings the slider up against the front and back planes of the slider apparatus. I am also wondering if anybody has experimented with this angle and found a magic one.

Because I feel it is at that point where the most pressure is put on the spring and that is where an OFF angled spring will put too much pressure on the top & bottom EDGES of the slide hole. And this, in return, will wear the slide hole into an oval due to sawing motion.

Damage? unless you use the slide a God awful amount (such as always playing in keys that require a lot of slide movements), a spring should last forever. BUT if a spring is wound against the grain to begin with, it can shear. Leaving you with 2 pieces that look for all the world like fish hooks. There is no way for me to tell if a person has loaded wire into a spring winding machine against the grain unless I use a microscope and can see striations on the wire. Striations are caused by the die. It is possible for a batch of wire to have been wound wrong. And no one would notice.

It is measured and specified from the bottom of the head to the start of the threads or to the start of the transition to threads.  You would then specify the length of the thread.   Obviously, specify the type of thread as Sheltraw wrote earlier.   Leonard
