Bridge pattern material

[paulrevenkojones at aol.com]

 David:

Any good plastics supply house will have a variety of grades and thicknesses of flexible plastic available. I use Duralar which is about 20 mills, doesn't tear, forms a clean hole with a punch, and comes in 4 x 8' sheets which I keep rolled up in the corner. Good for making agraffe templates, too. If you want a good punch set, look to Mazzaglia tools.

It's a little 5' 1" Knabe. The owner had in in 
their horse barn for 15 years in the Arizona desert. Sentimental value, money no 
object. No trace of serial number but it should be somewhere on the treble plate 
side underneath the regold. I'll include some photo's of the pinblock. 
WOW!? I'll check out your plastics reference Dale and Dean's suggestion for 
the drafters supplies stores. I had pondered David's idea of having the scale 
design calculated. I know this has been discussed on the list before so I need 
to research and find who can help me with this..... Any suggestions who? I'm not 
seeing anyone in the PTG?directory.??I'll be in Anaheim for sure! 
Thanks?to everyone! ?

? HEy Dave

  
? Impressive bridge cracks.? I have used 10 mil mylar for years 
  & it's a very good material. relatively stiff.? I am however in the 
  process of changing over to the David Hughes method of permanent Plexiglas 
  master patterns.... for the pianos we do commonly...let's see....which ones 
  are those?? For everything else 10 Mylar is fine. 5 mil ?I find too 
  flimsy.
? Check Plastics 2000 or other plastics store.? You may 
  need to? order in bulk but sometimes they have rolls they can cut off 
  of.

Greetings, 

  
I'm attempting my fist soundboard replacement a 
  la Bolduc and I'm looking for some Mylar to make the hole pattern in the 
  bridges. I've been to arts n crafts stores, office supplies and the big orange 
  builders store (you know the one) and all I can find is a 8x11 sheet product. 
  Apparently I can get this in a roll, as explained on the Bolduc soundboard 
  replacement video with Christian Bolduc, but what kind of supplier has this 
  stuff. Even been to a paper specialty shop but no luck. Any help would be 
  greatly appreciated!
