<p><br>Well.. tell them that my first results with side by side keys shows
a definant proximity problem (which I have at least one fix for) with interference.
These magnets are strong little bugger.
<p>This can be overcome by placeing the magnets on the backside of the
capstan with the magnets attracting one another in alternate fashion with
forward of the capstan with the magnets in opposition.
<p>It may also be that useing smaller magnets and allowing for closer placement
might work as well. Any other suggestions ?? I was told today by
one supplier that using cylinder magnets of smaller dimension might do
the trick as well as the magnetic field is more centered and cylinders
are a bit stronger then rings.
<p>I will try and work out the leverages involved on for putting them in
the backside, but initial DW/UW experiements show that the same kind of
results can be obtained.
<p>Course that raises the need to find a convienient regulating scheme
for those magnets aft of the capstan :) Not a biggie.
