<p>I made mine from an old inkjet printer axle, I used a lathe to
make the axle 6.5mm thick at the end. The cut on the end is about
1.5mm wide and 3mm deep. <br>

<div>Thanks for the reply. Good to see I didn't dream that. I'll
check those manuals. Do you happen to have a picture of the

<p>There are several color variants of the springs. If I
came across blue and brownish ones. I am not sure if
the colors where used for specific variants of the
keyboards. There are at least two keyboard variants,
the one with the metal key holders and the one with
the completely plastic keys. There is a slight
difference in length of the springs. When I take a
keyboard apart I sort the springs and when assembling
the keyboard I start with the black keys which is the
lowest amount of keys and thus springs. <br>
</p>
<p>Yes there was a tool, you can see a part of it in the
service manual of the Moog Micro and Multimoog service
manual. I made one myself and it makes aligning
keyboards much easier. <br>

Subject: [sdiy] Key spring colors on ARP synths<br>
<br>
Recently I have fixed some old ARP synths. They
all needed a really good<br>
cleaning of the keyboard. And as you know; you
need to remove those key<br>
springs to change key bushings and various other
fixes.<br>
The key springs have two colors; black and (dark)
red. Supposedly because of<br>
different tensions for the white and black keys,
since they have slightly<br>
different horizontal travel.<br>
<br>
But here is where it gets strange:<br>
Some of the synths I have fixed used black springs
for black keys (sort of<br>
easy to remember), while other synths used the red
ones for the black keys.<br>
So which is correct? Or did ARP change this
according to any sort of<br>
differences between the various versions of the
Axxe and Odyssey etc.?<br>
<br>
Anyone?<br>
<br>
