It's been years but I recall removing the bottom plate and maneuvering up a strip of DeOxit soaked paper between the contacts.Dennis AE6COn Sun, Jun 11, 2023 at 12:37 PM Roy Morgan <k1lky68@gmail.com> wrote:______________________________________________________________Might be blasphemous, but you might drill a hole in the side big enough to get a cleaning strip into the contacts.OR: Maybe the upper contact can be unthreaded out to allow a thin wood rod to clean the inner contsct and the upper contact in your hand to get polished.OR: does the bottom plate come off to allow access to the contacts?RoyRoy MorganK1LKY Western MassOn Jun 11, 2023, at 2:20 PM, Tim <timsamm@gmail.com> wrote:Those are really good keys. Mine is a real workhorse around here with the TCS, ARC-5 and the rest of the pile. It has a good feel and of course, is authentic... One issue is the flameproofness it is a bit problematic if you need to disassemble it to clean the contacts. Tiny, tapered pins, precision dowel shaft etc. Key Guru's advise that should be done by a good machinist with the proper tools (rather than my hammer and files...). Anyone got helpful hints? But still a winner around here, it has lots of miles on it...TimN6CC______________________________________________________________On Sun, Jun 11, 2023 at 9:34 AM Doran Platt <jeepp@comcast.net> wrote:______________________________________________________________Well, here's my key example, in situ, with a vintage ops position.
