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.

I used to work at a huge manufacturing/chemical plant. "Safety First" posters
everywhere. Every department had a designated safety officer(s). Cash awards
were given if a someone pointed out a safety issue.

As an IT tech I used to go everywhere within the plant. I won numerous
cash awards for pointing out safety issues but only after I had to convince
the safety officer of that department that it was an issue. Sometimes I
had to escalate the issue because the safety officer just didn't get the
point. The lack of common sense was really scary.

That's another good one. They wouldn't pay engineers for safety, or
other suggestions but they would pay hourly staff. I'd just point out
problems to my technician and he'd collect the easy money. Often it
was stupid things like a sign blocking an Exit sign, and such. The
safety people would get ****ed-off because they were supposed to catch
such things.

This suggestion wasn't specifically a safety issue, but I got paid on it
through the corporate Suggestion System that paid for suggestions that resulted
in a money saving process change.

My company was already in trouble for possible ground contamination in the
surrounding neighborhood - including the ground under the grade school
that was named for the company. One morning I was walking from the parking
to the security gate, a walk that took me down a public street along the
plant's fence. As I looked through the fence and down a road between 2
buildings, I saw foam bubbling up out of a sewer, breaking up into pieces
2-3 feet across and blowing down the road. Some of the bubble masses were
settling right up against the fence. Definitely not a good look for a company
already in trouble with the EPA.

I had a friend who was in management for that part of the plant so I called
him and asked him how I should report it. He told me that he would contact
the proper department. He then called me a few days later and told me to
put in a suggestion saying that the ABC department should be using anti-foaming
agent in the XYZ discharge system. He told me to route the suggestion through
his department. When I wrote up the suggestion, I added a few words about the
"bad look, especially at this time". About a month later I got a check for $3K.
That would be about $6.5K in today's dollars.

Apparently that "bad look" was worth preventing.
