Mike's Clock Repair

In for repair is a miniature Kundo 400 day / Anniversary Clock with a Kiennger & Obergfell movement.  Upon delivery to the shop the customer stated movement has not run in a very long time.

Observations:
1)  The movement was dry and dusty.
2)  The mainspring was fully wound.

Removing the plastic suspension spring protector on the back side of the movement uncovered a problem with the suspension spring.  The spring was spun way too much causing the spring to curl.  See below.  The arrow depicts the spring.
Here is a picture of the spring removed from the movement As "they" say, WOW
The suspension spring needed replacement.  The Horolovar 400 Day Clock Repair Guide provided information on the specifications for the mainspring thickness (.058mm).  According the the repair guide, the movement was manufactured in 1974 and made in West Germany.  I do hedge on this 
The movement was disassembled.  As mentioned before the plates and wheels were dry and dusty.  The mainspring  wa…

This post is Howard Miller Grandfather Clock model 610-481.  This is an Urgos triple chime, cable weight driven, with moon dial, seconds indicator, beveled glass, with two doors, lyra pendulum, night shut off clock.  This clock was shipped cross country and was badly damaged.  This clock is approximately 30 years old.  Here is a picture of the label.

Here is a list of the damage to the clock:
1)  Damage to the door frame - broken in 3 pieces.  The glass was in one piece.
2)  Movement seat (wood platform where the clock movement is attached to) one side of the seat was pushed to the back of the clock.  It was firmly jammed in the railing.  I have never seen this before.  No telling how this was able to happen.
3)  Chime rods significantly bent.  The initial thought was they would have to be replaced.  I was able to adjust the original rods satisfactory.
4)  Damage to outside of the case.  This was repaired.
5)  The clock movement is weight driven with cables attaching to the weights.  …

In for repair is a German mantle clock.  Here is a picture of the clock as it came into the shop:

Picture of the front

And the back
The maker's mark is circled.  The maker was not identified.  It is a shame because the movement was of good quality
As you can see it is a nice movement.  The strike is a rack and snail.  All the levers, wheels, and bridges are well made and solid..  The arrow shows the very cool design on the plates.

The pivot holes were tested and marked there were 12 pivot holes rebuilt.  Here is a short video showing the result of a completed bushing repair.  
Mainsprings were removed from the barrels and cleaned
All clicks, pinions, wheel teeth, springs are checked. After the rebuilding work has been completed, the movement is ultrasonically cleaned.  The pivot holes are pegged with pegwood, clicks and click springs are checked.  The clock is assembled, adjusted, and run on the test stand.
The clock has passed all testing and has been put into the case.  Here is …

E Howard Time only Tower Clock


South High School in Denver Colorado has one of the few functioning tower clocks in Colorado.  This clock is an E. Howard from Boston Mass.  This clock was overhauled over 5 years ago by a group from the NAWCC Chapter 21.  I was a member of this group.   It was a privilege to work on this clock.

The South High School Alumni Association contracted with me to be the caretaker of this clock.   Periodic oiling and general maintenance is performed at least 2 times per year.

I want to share some picture of this clock along with a couple videos.

In for repair is a Kienzel wall clock.  Upon initial inspection, the clock was missing side glass and would not run.  Further inspection after disassembly showed one of the mainsprings broke at one time and a repair was attempted.  More details below:

The side glass was replaced.  The glass used was single pane glass, custom cut.
The minute hand with the center bushing missing:
The minute hand attaches to the steel post not the brass canon pinion as shown below:
Some parts can be purchased and some parts can't.  This is one that cannot.  A new bushing was turned and installed.  The following images describe the process:
The brass rod used to fabricate the bushing.
Machining the bushing
The finished product, top & bottom

Here is the image of the hands attached to the clock movement 

Once the movement was disassembled, it was discovered that the mainspring was broken and riveted back together.  The only solution here is to replace the mainspring.  Fortunately, mainsprings are p…

Waterbury Regulator Clock

In for repair is a Waterbury regulator clock.  Here is a picture of the clock as it was brought into the shop.  This is a nice looking single train timepiece.  This is a timepiece because it does not play a tune nor strike the hour or 1/2 hour.
Notice the mainspring hanging out the bottom of the face.  The customer stated that winding the clock there is no tension on the wind and the spring is not building tension.  
This could be 4 things:
1) The click is damaged or broken. 2) The click spring is damaged or broken and causing the click to not engage with the click wheel. 3) The mainspring is broken. 4) The mainspring end(s) have disengaged from the barrel post.
Here is the clock with the face and hands removed.  The movement and case are probably a marriage for a couple of reasons:
1) There are two sets of movement support holes. 
2) The case looks more like a turn of the century case but he movement says WWII vintage. 

I will fill the screw holes and add 2…

The Teller House Floor Clock in Central City Colorado 

Repairing clocks sometimes become tedious at times.  There are times that clock repair becomes an inspiration.  This is one of those times.  I had the privilege to work on a floor clock at the Teller House Hotel in Central City Colorado.  I did not do this alone.  I worked with a team from the NAWCC local Chapter 21.  It was a chapter project.  Organized by Randy Schneider.  It is an honor to work on clocks of this type.

The clock is an American Renaissance Walnut and Burl Tall case regulator clock made about 1870.  Made by C.A. Jones Company Courtland St., New York.  The clock was brought to Colorado via Ox cart by Hense & Gottesleben watchmakers and jewelers they had stores in both Denver and Central City.  The clock was on display at their Denver location.   The Kirschhof family obtained the clock and in time donating it to the Teller House about the 1930s.

The clock stands 11’3” tall and is 3’ 8” wide.  A beautiful and ele…
