I am looking to propose a wippen replacement on a no-name, tiny baby grand.  Currently, the rep spring cord loops are breaking, the flanges are Billings style.  Does anyone have experience to share about converting the wippen rail to standard flanges?  I am thinking to adapt WNG wippens to this action.  Aside from ensuring the spread and differential will work, and get me close to the magic line and a decent action ratio, what pitfalls may be lurking for me? I intend to propose new shanks and hammers that will give a strike weight appropriate to make the action nice and playable, which it currently is not.  The board, block and strings were replaced (decently,) though all original parts remain, other than poorly chosen new hammer weights and terrible tail shaping.

I could just replace the spring cord loops and wippen cushions, though I would much rather update the action with new wippens.

If it is a no name piano why go through all of that work which is expensive and time consuming to put new WN&G parts in it. Brooks may be able to come up with whips that will work. New cords may be the best solution here

My experience is if the loops on the whips need replacing, so do the loops on the jacks if they have them. Not that bad a job once you get going.

Can you post some pictures of the whippens showing the billings flanges and whippen rail as well as some hammers, shanks, flanges ?
