We repaired a 240 from 1862 and used the Pure Sound wire (after advice from museum people), but I cant say that I am really satisfied with it. For the experiment when some strings broke, we put in Röslau 1½  - 2 less in gauge in some chores to measure the partials volume. so some notes had one Röslau and one PS (the 3rd was damped off) This might not be strictly science, I know. Aurally there was not a major difference  I used TuneLab for the measuring and it came out that the PS wire had hardly any partials but for nr 1 and <st1:metricconverter ProductID="2, a" w:st="on">2, a</st1:metricconverter> rather "dead" sound while the Röslau was rich in partials but did not have a modern sound though. Anyway, the piano was finished with Puresound and almost a year later the sound has not become better.

Pretty >nice system actually if you can find the felt to work with it. Try Fletcher and Newman <mailto:info_x0040_fletcher-newman.co.uk>. They used to supply it but I think it was from Whitehead's Royal George works, which is now defunct. Perhaps Laoureux does it. The French denizens of the list might have more information. As to the stepping of the felt, there is no cutting involved. I have posted some pictures of the way I have always done it, which is as near as you'll get to the process used by the original makers. They've forgotten how to do it now and stitch the felt instead, which is not nearly as good. The URI is: <http: pianomaker.co.uk="" technical="" shaped_damper_felt=""> The dampers illustrated are actually from a Kirkman, which has one long stepped felt in the treble and two pieces further down. It is the first you are interested in for the Erard etc. Unfortunately I have not taken a picture of the main press that I use to create the stepping after working the glue into the strip and before applying the under-cloth, but if you ask me I can tell you how to make a simple press that will do the job. The process is as follows: 1 cut the felt strip at an angle /__\ so that when the under side (top side on the Erard!) is pressed in the sides will be vertical |/\| 2. Twist a pencil to make a dot centrally every <st1:metricconverter ProductID="4 inches" w:st="on">4 inches</st1:metricconverter> or so along the exposed (wider) side of the felt as a guide for the press. 3. Turn the felt over (narrow side up) and run a line of white glue along the centre. 4. Drag a stout needle (say No. 23 piano wire) several times along the line of glue, pressing hard so that as the felt springs up again it absorbs the glue. 5. Line the strip up in the press and screw down, leaving the felt under pressure for a few hours to allow the glue to set, but not quite hard, since you need some flexibility to make the hump in the middle 6. Stick on the under-cloth, leave to dry and then trim the cloth flush with the felt using a very sharp curved knife 7. Use a second press to form the hump, as illustrated. 8. Mark a line along one edge of the undercloth to indicate the front, and cut up the strip into individual damper felts.
