bid and won on an old style clock

the “un boxing” !

old style rotating numerals cloak, some wear and cracking on the clear face plate. the clock, the clock works but the motor emits a grinding sound. in a quiet room very audible.

the back is clear plastic , apparently you set the time by putting your finger through he back and rotating the dials to the correct time

plastic style case

sort of a burl wood plastic color

removed the rear panel

you can see the rotating mechanism

the numerals are in good shape , several kits are available as stickers to renew the look , these are highly viable and still have good color

case interior with dial nightlight switch

front panel removed

I checked the paint on the wheels of the numerals, it didn’t flake away before cleaning. On some old devices the paint will simply flack away if distrubed

components cleaned

ready for assembly

plastic polish applied

reassemble of the wheels, checking the sizes of the hardware axles and screws

some silicone grease applied, the paint was flaked on the spring detents, left as is

installation of the detents

assembly

mounting of the motor

completed project

rear view

While the project was finished, the motor was very noisy, I tried to lubricate the sealed motor but it ended with failure. Most likely will sell for parts as the motor is not readily available for replacement.

The bulb will be replaced with a C7 LED filament bulb.

on the bench… continued

Now that I had worked on several coffee brewing machines the Cuisinart coffee grinder stopped working. The dark roast Starbucks french roast , finely ground, seems to have clogged up the machine. A lot of moisture from the oily dark roast clogged the machine over time and have appeared to stall the motor, Should have preventative maintenance done on a regular basis. This grinder usually gets several times a day use.

on the bench

hopper removed

several screws on the bottom to remove.

interior view, the bottom motor mount is cracked, motor is still secured

take out the control board , no components are toasted

right away check the fuse… ok

nothing looks amiss …take a couple of readings… all ok

closeup of components

checked out the wear on the brushes …. good

a lot of interlock switches to check out

pull apart some stuff to clean and check switches

more interlock switches

switcher ok

thermister …ok

all interlocks are ok and getting voltage to the motor leads from the circuit board…. Aha !!! the thermal limiter on the windings

yep , jumped it out and the motor works, pulled out carefully wired directly to winding wire.

replacement in stock, ordered assortment of common values from Ali express

add shrink tubing and carefully solder in place, lots of coffee ground on the blue mat today.

ever get those deep fasteners that a screwdriver cant fit into, hers may solution. Long Phillips drivers couples to a nut driver.

think I’ll have a cup of coffee now. fresh ground beans !!!!!
