As Terry mentioned his post, which for some reason I couldn't=
 reply to...?...make your own bass dampers.   It isn't hard and=
 they will work like a charm.   Duplicating a poor design is not=
 a good idea.  You will have to regulate no matter....

Bill's damper articles are in past issues of the Journal...he=
 also has a nice little jig for cutting the damper felt.

List,
Apologies for the attached picture, which however is worth a=
 thousand words.
I am making some modest improvements in a 1909 Hardman & Peck=
 upright. One of these is replacing the old dampers. I ordered=
 pre-cut upright dampers from Pianotek; they just arrived=
 yesterday and they are not right. Photo attached. What do I do?=
 I have to install them next Saturday.

            Jason,
            .
            From the picture I think you need a set of either new=
 style or old style dampers from Schaff or one of the other fine=
 supply houses.
            Measure the length of what you have.
            Page 94 of the Schaff catalog has Standard, New style=
 and Old style sets for the bass.
For the flat dampers I would order Schaff #1534 1/2. 
            Make sure you have enough of each kind for your piano=
 ---I.E. single-bichords and order trichords if necessary as they=
 don=92t come in the sets.
            These will usually work for most uprights.
            Personally I would order a few sets of each kind,=
 then you have a better chance of duplicating the felt in your=
 piano and you=92ll be ready for the next job without the shipping=
 wait.
Remember----- the closer you can duplicate the less wire and=
 spoon bending will be necessary.
            Redesigning the damper system is certainly an option,=
 especially if the piano has obvious damper deficiencies, but for=
 the first few times my advice is to go with what=92s there,=
 develop a technique, make some observations, then you can be=
 more confident with design changes as necessary.
