Vintage Synth Repair

I agree that the use of WD-40 is a very bas idea. WD-40 is a great 
product, but it has it's place...that place is not inside a Hammond.

IMHO, any kind of spray between the keys may fix things temporarily, 
but you will be taking the keys apart in the future to make it right, 
as I can't see that the spray will reach areas where it is needed, as 
well as the fact that a mechanism of this nature needs to be 
regreased. I would also worry that runoff from any spray and the 
grease residue would work it's way into the key contacts which are 
just below this mechanism, and not sealed very well. This would not 
be good at all.

I just took some pictures of this mechanism, and will post them on my 
Flickr site. Perhaps this will give those of you who have never seen 
this mechanism a better idea of what is involved.

Just a note; it was mentioned in one response that taking this apart 
and cleaning it would be an hour's job...perhaps for someone who has 
done it before, and has the tools and knowledge at their 
disposal...for someone who has never seen the insides of their organ, 
I would plan to spend several hours and perhaps a few beers on the 
job.
