This goes in the category..lesson learned..and also "have a slice of humble pie".

So a customer asked me to repair her 45 year old Yamaha console action..all the hammer return springs were "popped up".  I have done several of these over the years and used Tokiwa parts each time.  Then recently, I saw these flanges on Ebay at 33 cents each and thought that it would be cheaper but essentially the same flange as the Tokiwa.  Well, cut to installing the action and the customer played it and said "the action feels restrained".  So I took it back home and compared the flange to an old intact flange and sure enough, the Ebay flange butt cord string was about 1/16th inch and slightly longer than the original.  So I believe that is what is slowing down the hammer return and making it feel restrained.  So now I get to do it using the correct Tokiwa flange.

Patrick,

Did you carefully check if the replacement flanges had dimensional specifications exactly as the original Yamaha? The slightest difference could make for a noticeable touch change. The last time (3 years ago) I purchased Yamaha flanges they were just over a $100 for the set. I'm sure they're more now, but I had no fear the new flanges would seize up due to poor bushing cloth, and I experienced little to no lateral alignment or traveling issues, saving me installation time.

A simple test would have been to disengage several of the hammer springs and get the customer's opinion.  The new springs may just have been increasing the touch force.

So this is an interesting skill in customer service.

The customer uses words to describe something that concerns them. It is an attempt to name a feeling or sensation.

Step One should be working to understand the words. Can you feel, see or hear something that might be the sensation the customer is trying to communicate?

If not, keep communicating until you both are probably naming the same thing.

Then, as a technician, try to find a mechanical cause for the (now mutually understood) problem.

I have also learned (actually still in the process of learning) to warn the client BEFORE doing action work, that it's going to feel a little (at least) different afterwards, and there may be a need to adapt to it.  That way they anticipate a change, rather than be surprised by the change.

I had this scenario happen to me.  One trick that was slightly helpful was to reach in and, using finger pressure I tweaked each spring down to reduce their force.  It did seem to lower the playing resistance by a gram or two.

I do two or three butt spring loop repairs a year. I find it FAR easier to buy the cord from Yamaha and replace the cord loop instead of the entire flange. Every time I have gone the flange route I have had to spend extra time repinning as they're always too tight. Replacing the cord is not that difficult a job.

Hi Elisha,

if i saw your video correctly, you were using your method on a Yamaha with the detachable hammer butts, so they could be moved out of the way. How would your method work on actions where the hammer butts remain pinned to the flange? 

Thank you, Ed.

Do you use the dowel or cardboard method for cutting your strings to length, or do you have another (cooler) method? 😉

Your jig is quite fantastic, Elisha. I'm gonna make one. Do you have a special way of cleaning the old cords out of the slots, too?

This goes in the category..lesson learned..and also "have a slice of humble pie".

So a customer asked me to repair her 45 year old Yamaha console action..all the hammer return springs were "popped up".  I have done several of these over the years and used Tokiwa parts each time.  Then recently, I saw these flanges on Ebay at 33 cents each and thought that it would be cheaper but essentially the same flange as the Tokiwa.  Well, cut to installing the action and the customer played it and said "the action feels restrained".  So I took it back home and compared the flange to an old intact flange and sure enough, the Ebay flange butt cord string was about 1/16th inch and slightly longer than the original.  So I believe that is what is slowing down the hammer return and making it feel restrained.  So now I get to do it using the correct Tokiwa flange.

Hi Peter,

I've tried all sorts of improvised methods, but I've found that a 1/2" dowel works best. As shown in one of the videos I posted (not my works), using masking tape helps avoid messy cord management. Wrap the cord about 90 turns, tape it, and then cut.

Screenshot image is from that video.

Elisha,

Nice work! 

Do you use the dowel or cardboard method for cutting your strings to length, or do you have another (cooler) method? 😉
