Hi everyone. Happy New Year.
Some of you, I'm sure, will have tumbled to thus one already.From time to time we come across tuning condensers which are meant to be insulated from the chassis and bound to earth only through a heavy braid from one point on the condenser frame to one point on the chassis.So that they "ride" on the chassis in rubber grommets.But these grommets can perish with the passage of time ,sometimes allowing the condenser to rest on the chassis and often causing stresses and strains on the dial cord or an incorrect alignment of dial cards in keyhole apertures.
So we resign ourselves to having to "re-grommet" the tuning condenser -usually a fiddly job aligning condenser frame,grommet ,bolts and chassis holes , having first found grommets of the correct size. Recently, wandering round a $2 shop, I came across a product which I think can make this job easier.
They are called ,in the small packet,"adhesive skid protectors". In the large packet they rejoice in an unusual name -"hengtuo filzgleiter mit nage".My understanding is that the middle word is German meaning roughly"smooth glider ".Essentially they are small squares and rounds of dense sponge rubber with a sticky backing intended as non scratch feet , about the same circumference of a grommet. I punch a hole through two round ones with a wad punch to make a hole for the bolt . And then, because their special merit is that they are sticky you can stick one each on opposite sides of the chassis over the chassis holes so that aligning the various bits goes a lot more smoothly because the "un-grommets"stick in place . A bit of shrink wrap on the bolts reduces the risk of a short there when the bolts go back in.
I've done it a couple of times with success.If you have found this job frustrating this may help. Cheers.
