Unless they have been damaged = by being subjected to excessive moisture or chemicals, the more you play = them, the cleaner they get.   -----Original Message----- From: DIYAPASON-L@pipechat.org [mailto:DIYAPASON-L@pipechat.org]On Behalf Of Robert W.

I applied the DeOxIt with a chamois tipped plastic = tool made for contact cleaning. I think the mechanical buffing along with the chemical action helped. Before I tried this I was seriously thinking the contacts would have to be replaced.   ----- Original Message ----- = -------------------------------------------------------------- -------- I would like to hear from the list various ways of cleaning contacts.

If your contacts have been subject to some arcing, there may well = be a small burn groove in the plate which you will not remove with emery paper, this can be repaired and corrected by removing the plate and gently filing the contact edge with a fine file. If its a very small groove, you may get away with scrapping the contact edge with a steel scraper, you gotta get any small carbon deposits out of the groove. If your running magnets with these contacts, this treatment should last a fair while, If your running electronics with bronze = contacts, you will find they are far more sensitive and need cleaning much more often. For electronics, the contacts should be silver, not phospher bronze.

In our case: we did it to extend a TC 16' Bourdon in the Swell to the bottom by wiring the Pedal 16' "Soft Grunt" to do double duty. We also used it for all of the facades which previously had miles of offset tubing. We figured EP action couldn't be much slower than the original tubing runs and we were right, although the solution is STILL far from ideal (if there really IS such a thing on large-scaled, offset pipes in a mixed-action instrument!) In addition to the Note Actions, remember you'll also have to add Micro-Switches or some other form of stop action to make the additional stops play.   Dennis: this instrument is close enough that you can come up and try it out and experience how it is to do this for yourself before having to commit to it.   Faithfully,   G.A. -- Richard Schneider, PRES/CEO SCHNEIDER PIPE ORGANS, Inc.
