[pianotech] Jack Springs

[wimblees at aol.com]

It is from Schaff, item number 527A, upright jack spring.
The physical properties are equal taper from top and bottom, to a compacting of a couple of coils, in the centre, like each end.
The old springs were a double at each end, and the winding went wider in the middle.

 I've not used this one. I only have the 3776, which I use for all my spring replacements, and seem to work just fine.

I guess you are right Wim, I am just enquiring about others experience. Ethical is obviously the wrong word choice.

Not to get off the subject, but why would be unethical not to talk about product from a certain supply or manufacturing that you think is inadequate? I think this is one of the great things about this list. We tell each other what works and what doesn't work.

I was going to order some upright jack springs, as I am down to my last set. 
The diagram I see in the catalogue that it shows a new different spring. It appears to be of a larger guage. 
The spinet springs look the same. 
Would someone like to comment on these new springs. 
A fellow tech, told me of some new springs he was supplied in Canada, and he didn't like them, saying they were harder to install, and were noisier. 
I think that these must be the ones he was referring to, the Canadian supplier obviously is supplied by the US firm. 
He actually talked me out of my second last set. Now I see what he was referring to.
