A personal "best". 1

[itsmoked]

Well, I should probably call it a 'personal worst'.

I stumbled upon this beauty. Note the wood wire-insulator. The complaint is that it has all devolved into needing additional work with a pencil in thru the 'port' to get it to engage.

The Central American flavour of Loomex or Romex uses 7 strand wire rather than solid wire.
I found a unique splice in an attic. Someone drove a small nail through one side of the Romex, through one of the conductors and into the ceiling joist. About 1/4 inch was left protruding.
They drove another nail through the other conductor into the next ceiling joist.
They then fed the branch circuit by winding one wire around the top of each nail.

I really really want to know what the problem was that led to this as the solution. For the life of me, I can't figure it out.

Huh, images still not working I guess.

Dave and Bill those are horrid examples!! (Shudder)

Gunnar; It looks like they brought the power there down that white door-bell wire stapled to the ceiling trim. Lovely. Freak'in lovely!

Jeff bet I know what this is...
The contactor was starting to buzz. Corrosion and build-up on the armature. The "spring and lipstick" is a subtle 'helper' to provide that wee extra that was needed to get a full armature seating to kill the buzzer.

I'm getting an industrial oven going and when I left I told them the set screws holding the blower (14 inch diameter four inch deep squirrel cagey thing) to the motor shaft were all frozen. They said they'd get it off for me so I could put a new motor on it.

Today I get back there and they've taken a hack-saw to the motor shaft and cut the shaft off above the blower coupling. I was now looking at a motor with two NonDriveEnds! Looked pretty peculiar. I got two new contactors installed and the new motor installed and asked, "Where's the blower?"

A guy called "Butter Cup" brought it out. The big shaft, about an inch in diameter, had all the set screws drilled completely out. New holes were drilled and tapped. One was vaguely radially oriented and the second one was... a chord. The new "set screws" were grade 0, one inch long 5/16" bolts. They informed me that the shaft and come off a crumbled plate that had been riveted to the back of the squirrel cage. They'd then welded the shaft/collar directly to the blower back - as close to centered as they could get it..

We put it on and when I turned on the motor the 6foot x 6foot x5footH oven shook like a constipated dog.

I condemned it. As I loosened the radial bolt with a 4 inch long 7/16" wrench the setscrew-bolt twisted off at the collar surface..

Have you never heard of "washing machine races"?
