[Elecraft] Advice needed on stripping enameled wire

[Brett gazdzinski]

The best way I came up with was to place the toroid on the edge
of the table, and to hold it in place I used a roll of electrical tape
with the spool of solder on top.
The wires hang over the edge, and I bend them down somewhat.
I turn up the heat on the soldering station then do the 'blob'
starting from the cut end of the wire and working up to real
close to the core, then clean the iron and work down from the core
feeding new solder the whole time.
I inspect the wires after, and scrape any stuff off with an exacto
knife.

When I mounted the toroids, I left the wire long and ran it 
to the NEXT solder pad, so it was soldered at its hole using plenty
of heat, and also soldered along its length to the next pad.

I was very careful to keep the wire over the trace and not
short anything.

95% of the toroids had another pad close.

That also left some extra wire, just in case, and
I had no issues removing all the toroids to remove a turn.
(removing a turn seemed to do nothing...)

After all the reported problems with the solder on the toroids,
I was not going to have any issues, and did not.

I thought soldering the K2 was easy and fun, at my age, I need
the lighted magnifier, but any time I have to deal with NEW clean
parts is a treat, I often build things out of 20 year old parts,
which require a lot of prep work before they will take solder.
