yamaha butt flange repair

[Ric Brekne]

Hi Rick

I see you've got a lot of answers in and no doubt someones already 
supplied you with a good solution.  Just thought I'd throw in that 
replacing the silk threads is a really easy job and if thats all thats 
failing the flanges I'd have replaced those and re-installed the 
origionals.  The cost of new parts and the amount of work needed to fit 
them often pans out as in your example.

I re-machined a set of new Steinway hammer flanges about a year back 
because the centerpin line was 1 mm farther out on the new ones then the 
origionals... and I can not find a source for new flanges of origional 
dimensions.  All the work involved in that really ended up not being 
worth my time.  The older O I just got finished with had the same 
problem.  I found it much quicker to use the origional flanges 
installing new drop screws.

I get the feeling a lot of folks opt for putting in brand new parts when 
the old ones can be rebushed or refurbished without much work thinking 
they are going to save all kinds of time... and it isnt necessarily so.  
Course many times its more then appropriate to opt for new parts as 
well.  But  sometimes perhaps it might be just as well or better to use 
the old ones.

Just my 2 cents
