Keeping this relevant to the wRec, the following video shows us how to replace
the power cord on a circular saw.

If you start at 4:30, you will see a technique for creating a "ring connector"
from the bare power cord wires. What do think of this technique?

I have some issues with some of the other things he says and does in the
video, but this question is mainly about the connection method he uses.

The proper method is to crimp a ring crimp terminal onto the wires, if there
is space -- which looks questionable in this case.

In the old days, manufacturers crimped a hollow brass eyelet around the
stranded wire, creating a solid metal ring, but I have not seen that in ages,
and it wasn´t something that one could afford to do at home anyway.

Failing that, I twist the copper strands into a solid bundle and tin the
bundle with liquid rosin flux and radio solder, making a solid wire. This is
bent around the terminal screw in the direction of tightening, and the screw
is tightened. The wrap direction is critical to ensure that the wire does not
squeeze out from under the terminal screw.

One could also form an eyelet as shown in the video, and then tinned the
copper wire to solidify the ring.

The key is to ensure that thge terminal screw cannot cut the wire while being
tightened.

I would not have drilled the plastic to get to the torx screws in the plastic
handle. One can get torx screwdriver inserts with 6" shafts.

I could not see how the cable was clamped on entry to the saw handle, but
this area is critical.

BTW...I also don't like the fact that he used a 3 prong plug and cut the
ground wire off on the inside, saying that using the 3 prong plug "doesn't
hurt".

I don't like doing that more on principle than on any actual "danger". I don't
like giving the user the impression that a device is wired in a certain manner
(e.g. equipment ground is present) when in reality it is wired differently.

I don't think that that tool would be approved by OSHA for use on a job site
if they knew that the ground wire was not being used.

Years back, one of our techs was required by industrial safety to add
a 3-prong cordset to a plastic wall clock. I asked what he did with
the green wire. "Connected it to the case, of course." The inspector
was happy.

That's what happens when they hire safety personnel with no actual safety knowledge just so
that they can check the "Hired Safety Personnel" box.

Or when people are told to follow the rules, rather than understand
the rules. BTW, this was in IBM.
