Yep,total agreed and appreciate your comment.
I know i made a mistake.
to figure out how bad that is.the Torque has been involved.
So have you got some informations on if my testing result is okay for that tuning pin?
i really have no clue now.why the testing figures can be huge different with 2 different testing methods
1 ,tune piano from sharp to normal then test with torque wrench
2,tune piano from flat to normal then test it with wrench again.
which method is the Marginal point 70 inchpounds related to?
is that the figure which is taken using a certain method?
best regard,
Harry

> > The 1869 instrument had been kept in an unheated room in a stone-walled house without moving air. For some reason the very bass end of the instrument, possibly being in the corner, was damper than the rest and two bass wrestpins were rusted in place. We tried a judicious amount of WD40, arguably appropriate in a rust situation, and they didn't move. In fact they broke off. We tried using screw extractors and they didn't respond. We ended up having to drill two new holes in the cast iron, threading them, and drilling the appropriate holes in the wooden wrestplank below.
> > We were careful and judicious in our choice of drill sizes. But the new holes have continued to give problems and it might be that the WD40 has crept into the wood. I used shellac in the holes, CA, reversed sandpaper, and the pins are just about satisfactory. But the bottom line is that the WD40 although seemingly excusable in this difficult circumstance, did its fair share of no-good. Or perhaps our holes we drilled were a touch on the too-large size. The pins are tunable - just.

Sorry to ask ,if i didnt get you wrong.
Do you mean you ever put a judicious amount of WD40 into the tuning pin holes before you installed the new pins?

Subject: RE: Aid i took after using WD40
Actually I have an unfortunate experience in using WD40.
Many of the late 19th century Broadwoods used a metal plate above the wrestplank with tapped wrestpins.
The 1869 instrument had been kept in an unheated room in a stone-walled house without moving air. For some reason the very bass end of the instrument, possibly being in the corner, was damper than the rest and two bass wrestpins were rusted in place. We tried a judicious amount of WD40, arguably appropriate in a rust situation, and they didn't move. In fact they broke off. We tried using screw extractors and they didn't respond. We ended up having to drill two new holes in the cast iron, threading them, and drilling the appropriate holes in the wooden wrestplank below.
We were careful and judicious in our choice of drill sizes. But the new holes have continued to give problems and it might be that the WD40 has crept into the wood. I used shellac in the holes, CA, reversed sandpaper, and the pins are just about satisfactory. But the bottom line is that the WD40 although seemingly excusable in this difficult circumstance, did its fair share of no-good. Or perhaps our holes we drilled were a touch on the too-large size. The pins are tunable - just.
We've "got away" with the repair but I'm less than wholly comfortable about it.
A potential dispersant of the WD40 might be acetone or dry-cleaning fluid but no doubt that might bring its own problems.
Best advice in this circumstance is to see how it goes, and deal with whatever problem that might develop when it does.
Best wishes
