K2 Encoder - bare wires?

[Fred (FL)]

I'm building K2 # 5422 - and just finished the Control
Board, and the Front Panel board.  Assembling the FP
board to the front panel and encoder, etc.

K2 Manual calls out "cut 4 hookup wires, 1-1/2" long,
remove insulation" .....

Are they talkiing remove insulation from each end of
each wire, or making the 4 wires BARE?

I already messed up one IC install - which took a
solder sucker removal operation - don't want to go
that route again!

I wanted to thank all this list's members for the
great help and advice you've given me already in the
K2 # 5422 build.  Its a good feeling knowing there's a
group  of experienced experts, and builders out there
in the wings!

Thanks, 73's
Fred N3CSY

Fred,

Yes, bare wire is what is called for - I usually just use some of the longer
component leads, but the supplied wire works fine, just remove the
insulation from a length of the wire and cut the bare wire to length.

After the encoder is soldered in, the leads are sufficiently short that
there is no danger of them contacting each other.

Fred,

I read it as bare wires and installed accordingly.

Yep, bare wires.  It took me by surprise as well (yesterday) but I just
followed the directions exactly and all was fine.

Also, there is a thermistor board that you'll have to build and install,
again using 8 bare wires.  That operation was a bit of a pain since the
board is so small and I have no 3rd hand.  When you do that board, keep
components flat and your solder joints thin and flat against the board.
You'll want this thing to be skinny enough to fit in between other
components.

Hi

Here is a little trick I use when building the thermistor board. After
installing all of the components place the board flat on top of 2
thicknesses of the black anti-static foam. Stick the bare wires (I use
resistor leads) into the holes on the board and down through the foam to the
workbench. Then solder all of the wires on the board and clip off the excess
flush with the board. Remove the foam and bend all the wires down 90 degrees
so they stick down from the edge of the board much like a resistor pack. The
board should then be easy to install on the RF board in the K2

Fred,
Be light and quick when soldering the bare wires to the encoder.  Too
much rework or too much soldering can melt the plastic and internals on
the encoder, making for an expensive replacement (not that I, uh, have
any, uh, experience in this are, of course).
