You may remember a few posts of mine from a while back - I was trying to decide what to do about the hammers on my 1930s Rogers Grand. Heres my current status...
In the end I had complete new hammers made to pattern by Abel and hung on new shanks. I fitted these roughly myself then got a technician in to do the casting and fine alignment. They haven't been voiced but other than that they are quite acceptable. I wish now I hadn't had them hung on the shanks. He could have done that - problem is a few of the shanks had to be mounted a mil or so forward to get the right striking line. I Assume this is ok as long as the jacks are adjusted to match? can't feel a difference I must say.
The trouble is the piano is still crap to play. Very uneven (despite regulation) and sluggish now (and heavy touch). I spent ages adjusting the weights but it is still not brilliant. Some of you folks warned of that (after I'd bought the new hammers
![Wink :wink:](./images/smilies/icon_wink.gif)
The centres were very bad in the old hammers so I suspect that they aren't great in the whippens/levers. Some of the jacks are right on one side, and as someone mentioned, the whole action wasn't designed for the heavier hammer felt I now have.
This all leads me to think, "why not repace the whippens for new ones?" that would mean that most of the action is brand new; the keys are all level and in very good condition, and hopefully modern whippens are likely to accomodate the weight of modern felted hammers? On this basis I found a company in the US who can supply renner whippens at a very reasonable price. With the strong pound at the moment I can get 90 for £550. I ordered one to try it out, not wanting to get my fingers burnt like I did with the hammers. It came today and I fitted it. Wow. what a difference. The treacly sluggishness has gone, the repetition is far better, the control is much improved and the touch weight is lighter (this even before I hook up the little spring on the back).
As you can imagine there are a few subtle differences between the whippens; there is however one major difference: The little short piece with the scew hole that you use to mount the whippen into the action is about 1/8" longer than the original. I found I had to put a washer between the whippen and the action when screwing it on to get it into a better position. When I replace all of them I'll be able to move the mounting rail back a little, but right now the washer is best so I don't mess up the others.
My question is this: What do I do about the change in height in the mounting piece? Should I reduce the height of the rail? I have to admit I did some reversible damage and took a small piece out of the rail carefully with a chisel to fit this one, but I don't fancy doing that another 87 times. I guess the discrepency could be taken up by regulating but I assume that the resting position/angle of the whippen is fairly important as the way it lets off will be affected otherwise.
I've taken a few pictures and put them on my website at www.jamespyke.plus.com. Your thoughts would be appreciated!
