Default Skil Saw Model 77 - How to repair?



wrote in message
...
I have an old Skil Saw model 77 from the 1960's or so. There was a
problem with the switch, so I took it apart. There are two wires from
the motor that need to be replaced, so I then took the whole thing
apart. I thought replacing the wires would be an easy thing, but the
wires feed into something I don't know what it is called as seen in
the following pictu

I'm fairly confident someone will offer up the solution to take it to
a repair guy, and I did, an authorized Skil Saw service center, and
the fella' there said it would be too much work. Now I am taking it
upon myself to make this thing work again.

In the picture there are two wires in the upper left hand corner.
These two wires need to be about 1/2" longer so that new terminals can
be attached in order to attach them to the trigger switch. You may say
to yourself, or me, to simply add wire to the existing wire. Well, the
existing wire is very old and is falling apart by just looking at it.
So, I would like to replace these two wires.

Questions:
What is the thing the wires connect to?


Looks like the field coil assembly.

What is this method of wire connection?


Somewhere in there, the stranded wire is soldered to a thin wire which makes
the winding.

Why are the wires attached this way?


Because that's the way Edison (or Tesla maybe) did it and it was good enough
for him. (Joking)

How do I replace the wires?


The best way you see fit. If it were mine, I'd strip the wire back an inch
or so and using a bell splice (and solder), I'd add a couple inches of good
(new) wire. then, I'd cover the length of old wire, the splice and an inch
or so with shrink tube. Then I'd cut the new wire off as needed and attach
to the switch.

Trying to get into the coil to attach new wires is going to be quite the
task...

Best of luck.
