Effective immediately, I'm no longer taking in work until, at the earliest, the Summer of 2023.  This is so I can address my back-log and will only make exceptions for prior commercial customers. My back-log is such that this is, at best, a guess and it could be later.   I will remove this banner when things change.   I do not make any recommendations.

However, I will take in the Hammond movement but not the entire clock until the Summer.

Hammond Clock Motor (Rotor) for the Postal Telegraph Wall clock




    My business is rebuilding your original motor, when possible.  Most Postal Telegraph’s
were made without a motor and the first section deals with those situations.  The second section
deals with customers sending in the Hammond motor or the clock movement with motor or the entire
clock with a Hammond motor.





    Postal Telegraph’s were mostly made with a movement that did not have a motor (as pictured
directly above) and used a coil to generate an eletro-magnetic field that would drive an internal
disk.  This is considered a (Time Only) movement and an overhaul on a time only electric is $400.00
plus $30.00 shipping, assuming you only send in the movement.  The movement overhaul does NOT
include the coil ($150.00), so that would be added to the cost of the overhaul, if needed.
Coils are not sold separately.

    If this is what you have and you send it in with the entire clock then it’s the same as
above with shipping increasing to $175.00 in order to cover the additional labor and shipping
costs ($450.00).

    Complete movement overhauls or if you send the entire clock takes 6 to 8 months.

    The confusion is that the picture above is the back of the clock and Postal Telegraph’s with
the Hammond motor look identical.  It is not until the backing is removed and any movement outer
covering removed until we know if it has a motor or not.  I can and do service both and if you’re
sending the entire clock, then it’s my problem and not yours.

    You can send a picture of the back and sometimes I can tell if it has a motor or not to
mike@telechron.us






    The picture above is the back of the first movement used in the Postal Telegraph and I
DO NOT work on these but do work on all that were made after that because they contain either
a clock motor or a magnetically driven disk.  The above was only used in the first production in the
late 1920’s and all others have a motor or disk and were make in the 1930’s.  Hammond produced
clocks from 1928 to 1941.

    Also this clock will say bichronous, which means that it has an auxiliary system with
a mainspring that is suppose to "take over" once the power is off.  Some of these have the type
of mechanism that has leaf spring limiters to regular the time when the current is on and I do
not work on these.  If you or a local clock shop can take the back cover off and send a picture
of what's underneath, then I can tell you if I work on it or not.  The word bichronous can be on
the front or back or both.  Even with that word, I may still be able to work on it but need that
picture to be sure.


Postal Telegraph's with a Hammond clock motor




    The rest of this Web page concerns itself with other clocks that the Hammond motor is
installed in or just the motor itself.  Here the clock and/or back will state synchronous, which
means that it runs on electricity and has no back up for a power failure.

    Rebuilding these motors cost $250.00 plus $20.00 priority mail (Canada is $45.00)
and has a 2-year warranty, which brings your total cost to $270.00.

    I must have the old motor.  If you don't have the motor then I must use one from inventory
and that adds $100.00 to the total and it too would have to be rebuild, so the time frames would
still be the same.    For a total of $370.00 if I use and rebuild one from my
inventory and that includes the $20.00 shipping and handling.

    In addition to the picture above, these motors are identified by their 15 tooth
brass pinion (gear).

    I do not know of any substitute.

 	My turnaround is 4 to 6 weeks for motor service, 6 to 8 months if the clock is sent
with the motor, or if the movement is overhauled.

    I no longer offer expedited service.

     If you want to send in the clock for motor or rotor replacement, please be advised that
your costs will increase by $140.00 with everything else staying the same. The increase
covers the increase in return shipping and insurance and includes my labor charge of $100.00
for the replacement service.  I can ship at that price for clocks up to 22" in diameter
($410.00 total).

Overhaul Hammond clock motor  $250.00
Labor and cleaning of movement  $100.00
Return shipping and handling  $60.00 to $100.00
Total  $410.00 to $450.00

    The above assumes you ship the entire clock and does not include a warranty on the
movement (mechanism) because that may need to be overhauled as well.   Most times the
movement does not need to be overhauled but if it did then you're looking at an
additional $400.00 for a possible total of $710.00, then the movement would have the
same 2-year warranty as the motor.

    I’ll not ship until I received payment.   I ONLY accept money orders,
certified checks, or company checks for payment but repeat customers may use personal checks.
Normally shipping takes place one week or so after I receive payment and thanks !

    All checks must be made out to Mike Murray because I gave up my business checking.


	One thing you can do before you send in the motor is to take a Multimeter or
Volt/Ohm meter, these are less than $20.00 at any hardware store, and with no
current on the motor, set the meter to Ohms and touch the two leads to the end
of the wires and see if you get a reading.

	Just about any reading is a good one and the lower the better.  But if you get no
reading what-so-ever then the motor’s coil is dead and you will need a coil as well.

    I do NOT sell these coils separately but do as part of a motor overhaul they
are $150.00 each but do sell # 60 or # 14 Telechron coil for the same $150.00 plus shipping.


        For return shipping I use USPS for all motor shipping and
UPS for complete clock shipping.  If you want to use another carrier
then you will have to arrange everything for shipping, meaning I hand the box to the
driver, get a receipt and nothing else.

    If, for any reason, I cannot rebuild your motor or I cannot salvage an
exact substitute, then I’ll return your motor at no charge what-so-ever, unless you
send the entire clock, then I charge for return shipping, which is usually $50.00 to
$75.00.



    All checks must be made out to Mike Murray because I gave up my business checking.

    Please do not send any money or check with the clock.  However, if you are
sending a Hammond motor only, prepayment is always welcomed because of the
relatively short turn around time.

    I would like payment by, certified check, personal check, business check,
or through Pay Pal or Square, which is the only way I take credit cards.  I
do prefer a check over Pay Pal or Square because Pay Pal and Square take 3%.

    The 3% is added to the total bill if you use a credit card.

    With either Pay Pal or Square, I will send an invoice to your E-mail
address.  Here you are dealing directly with either service and not me.

    You do not have to be a member of Pay Pal or Square in order to issue a payment but
the 3% will be added to your total bill.

	All of the added fees are exactly what either service charges me for taking your
credit card.


You should realize that a Telechron coil will effectively replace the Hammond
coil, if the need should arise, with the same wattage considerations.  A # 60 or # 14 Telechron coil
work well and I do sell those for $150.00 plus shipping.
