hey Horace, check this out, Rosemill.com has a powder called"Cherry Red" for heat treating. Not sure it can work for us but it hasvarious apps for general shop use. Since the B word came up are youaware that the bolted in V-bars are not solidly constructed but are hollowwith a honey-combed center. So much for the mass theory. Can't keep up with this discourse since no internet connect while house rebuilding. The reason behind using pinned agraffes for me would be for stabilized string leveling,not sure if that has been mentioned yet.

I'm not sure. I used to get them from Bosendorfer, but used up the last of that supply a year or so ago and haven't really looked since. Brent might know. > And for that matter, is there a third-party supplier of pinned agraffes? Not sure...maybe Jurgen or Jahn. I don't think anything like that has been made in the U.S. since the middle of the 19th Century, and then only as pilots and/or for patent purposes. Del might know more about that part...wish Harold Conklin were still with us, I'm sure he could shed some light, too. In terms of the electorless nickel plating: What I've done so far is, I admit, not terribly scientific. I get appropriate agraffes, polish them in a tumbling rock polisher until they sparkle plenty (thanks to those who pick that one up), and then take them to whatever plater is willing to play with small lot jobs that don't pay very well. In the SF Bay area, there are a couple of places which have done this with good results: http://www.eps-plating.com/ http://www.electro-coatings.com/ If I were doing production rebuilding the way some on this list do, I might look for places outside CA for this kind of work. The CA version of the EPA (and, especially the five counties around the Bay) have exceptionally strict (and very expensive) controls on this kind of processing, so the costs aren't low. On the other hand, the fact that firms like this are active here also means that the business is sufficiently lucrative for them to stay. In any event, as we so often discuss on this list, if you want quality work, you have to pay for it... Sorry I can't be of more help with the pinned agraffes. I'm sure someone else will have better answers. Best.
