Stronghold Iron Frames
Post by stephen thompson »
Good folk of the Piano Forum
I have recently tuned an ancient upright from the firm Papps of Portsmouth and found several pins unable to hold the
required tension. Adopting the traitional method of pin replacement, I discovered there was no wrest plank, but a gaping void
of about one and a half inches deep. Further inspection revealed the phrase "Patent Stronghold Iron Frame" on the
makers plaque situated on the fall. The piano trade has over the course of its history thrown up many patent ideas to vex the
unwary tuner, but this is the first time I have come across this particular variation.
Can anyone offer solutions to an effective method of pin replacement and offer further insight to this system.
Yours sincerely

Re: Stronghold Iron Frames
Are the pins threaded like some old Broadwoods and Brinsmeads?
Like Barrie, it's a new one on me.

I've tuned one...or had a go at it, anyway. Most odd; it was two iron frames in effect, with slightly elliptical holes and the two 'frames' exerted tension in different directions on the pin, or something. I vaguely remember asking Bill on the history forum - or maybe off forum, can't remember - but he did have a little info on them, I think. Ask him nicely!
I play for my own amazement...

were the pins jumpy on the one you did Gill ? I assume the pins were OK on yours
Sephen is there any way of off setting the two frames more, to add more friction.
Love to see one did you take any photos

It was a complete sod to tune, yes, as the pin shot past where it ought to be.

Re: Stronghold Iron Frames
There are loads still around.
The secret is to lift the pin slightly so the grip is released, and the pin moves nice and smoothly. since the pins all have a distinctly raised attitude to start with, a Blüthner lever with a good angled head helps.

If you're buying a piano, try as many as you can and buy the one you like, not a similar one of the same type.
