Upright Wippen Rebuilding Questions

[Farrell]

Thanks for the input Kerry. A couple comments.

Regarding hide or Titebond. I know this has been gone over a billion times, but on this action several jack flanges had been repaired with yellow wood glue. The original hide glue came off effortlessly with a little water action - wippens cleaned up perfectly. The wippens that had yellow glue applied (of course I don't know exactly what it was) did soften, but required a fair bit of scraping to thoroughly clean it. I just delight in how easy hide glue is removed.

Mutton fat! Yikes! Where on earth would I find that? And is that something that will not affect the action cloth on the damper lever, and is that something that can be expected to last for many decades?
