  • 1.  Attempting the impossible?

    Posted 20 days ago

    Did a pitch raise and tuning on an old drop-action Baldwin console last week.  One of the sloppiest actions I've ever had the "pleasure" of working with.  No bobbling hammers.  No excessive lost motion.  Repetition is ok for a 2nd year student, but this teen is enthusiastic about the piano, and I'd like to be able to give him something other than this limp, virtually weight-less action to practice with.  The piano has good tone except for a few "tubby" bass strings (which I will investigate further on my next visit), and other than the action and those handful of single wound bass strings, it's in decent shape.  

    His Mom just lost her husband, so I'm trying to figure out what the least costly (and labor intensive) way might be to improve this action weight and repetition without pulling the action (rubber grommets) and replacing hammer springs (or otherwise costing them a small fortune).  The key bushings appear slightly swollen, but with as light as the action is (and no sticking or sluggish keys) I'm reluctant to attempt ironing or easing them.  

    Perhaps it's impossible with a limited budget, but any economical suggestions for improving repetition (which he'll probably need by his 4th year), and/or giving him some action weight to develop those hands would be much appreciated.  Many spinet actions have light action weight, but I think this one is probably the "sloppiest" I've encountered.  I've never attempted adding key weights before so if that's the best option, any pointers may be helpful.   

    Thanks.

    Hi Tim:

    I would try adding Jiffy Leads/Weights to the back half of the keys.  They are easily removable if you don't like the effect, and not too expensive.  No need to remove the action, and you can move them around easily.  I usually just glue them on, but they include small screws to make the installation permanent.  Drill small pilot holes if you screw them on, otherwise the screws can split or splinter the key sticks.  Call them bandaids if you wish, but in a low budget situation they do help.
    Another thing you could try is to look at the hammer spring rail.  Where it screws to the action brackets, there may be some think punchings in between the rail and the brackets.  You can remove them which will move the rail closer to the hammer butts, and that will add more tension from the springs, and you won't have to replace the springs.  Easily undone if you don't like the result.

    Not remembering the details, but I have a colleague that has used fishing lead weights, I think he hung them off the bottom of the stickers. Might be less expensive?

    In addition to leading the keys one way or another, I'd also recommend regulation. Yes, it can be a little difficult to do on a drop action but it's totally possible. Most spinets I see have never been regulated, which often means they feel very sloppy. Will they ever play like a grand? No. But will it be better than it is now? Absolutely. You can set a two hour timer and do the best you can within that timeframe. Just doing the four basic steps for aftertouch (let-off, dip, blow distance, checking) will most likely make a great improvement.

    Tim, does this "old drop-action Baldwin console" have the fake buckskin substitute known as corfam? The early iteration was black. In my experience, the main fault of this version is that the glue joints in the hammer butt fail, making its contact to the jack tip irregular. The butt catchers shed lots of black dust but still tend to function acceptably.

    The next iteration, which is tan like real buckskin, is horrible. After a few years (or less) the stuff became very hard, disrupting back-checking, and the the corfam-jack contact very noisy. If your action has this stuff, replacement of the corfam with ecsaine)or genuine buckskin) is the solution, but it's a lot of work (i.e. $$ to be paid to you).

    While you indicate there's no problem with lost motion, these key sets often have minimal leading to the extent that keys may not return (especially when using the sustain pedal). As Paul wrote, jiffy leads can be a fast way to add weight. You may find cutting the weights in half may provide you with sufficient weight to make the action function better.

    Good luck!

    Tim, usually this action will require key bushings, replacement rubber grommets, and most importantly, reweighing. 

    The quick and dirty approach is to backlead the keys to achieve a decent 50 to 52 G down weight. My experience with the Baldwin vertical is that it becomes a decent instrument when properly weighed off. Unfortunately some of the slow key return is in the bad balance rail bushings. I usually do a balance weight assessment with the standard sample C / C sharp throughout the piano. I usually find that the sharps have 5 to 10 grams higher down weight than the naturals, which I find sometimes below 40 G. I have done this with normal leading practice and I've done it with Jiffy key leads.

    Please forgive me for ignoring the black Buckskin part of this discussion.  Unfortunately, the black material sometimes becomes sticky, causing real performance problems,and eventually thoroughly disintegrates.  Replacement is eventually required.

    I understand that we should try to improve a spinet piano the best we can, especially when the customer tells you there is not enough money. But regardless of how much work we put into the piano, or what the customer can afford, it's still a spinet. Therefore, we also need to educate the customer about the importance of a better instrument, especially when the player is showing signs of becoming much better in the near future. Explain that the money spent on the spinet will never make it a suitable instrument, and that they should spend that money on a better instrument.

    I would agree that a discussion about saving towards a better instrument should be had (if it has not already). Perhaps you can be instrumental (pun intended) in acquiring one?
