Introduction
This article summarizes the conditions and repair steps as presented. The focus is on selecting a thin double‑sided adhesive tape for reattaching a dial plate on a Howard Miller calendar/time clock, along with alternative attachment methods.
Initial Question and Requirements
Clock type
The clock was a Howard Miller calendar/time‑only model with the movement repaired and reinstalled.
Original attachment method
The dial plate had originally been attached using double‑sided adhesive tape.
Need for thin tape
A thin tape was preferred so the dial plate would sit flush and avoid interference with the calendar hand, which sits close to the face plate.
Goal
Find a reliable, thin adhesive option suitable for reattaching the dial plate.
Recommended Adhesive Options
Spray contact adhesive
Spray adhesives such as 3M Super 77 were suggested as an alternative to tape.
Contact cement
Contact cement was mentioned as another possible adhesive option.
Thin 3M/Scotch double‑sided tape
A specific thin tape was recommended: 3M/Scotch double‑sided tape with label number 34‑8724‑5195‑9.
Long‑lasting performance
One user noted having a roll from the early 1980s that remained in excellent condition despite heat exposure.
Rodico as a reversible option
Rodico was suggested as a removable, reversible adhesive alternative.
Concerns About Tape Longevity
Durability questions
One response noted that tape, regardless of brand, may not be a permanent solution.
Potential for better mechanical options
A request for photos was made to determine whether a more secure method might be appropriate.
Risk of future detachment
Adhesive‑only solutions may degrade over time depending on heat, humidity, and surface preparation.
Clearance considerations
Any adhesive method must ensure the dial plate remains flush to avoid interfering with the calendar hand.
Preference for traditional methods
Mechanical fastening was suggested as a more historically consistent and durable approach.
Final Chosen Solution
Switch to screw mounting
The restorer ultimately decided to drill four mounting holes in the dial plate and use brass screws.
Historical consistency
This method aligns with traditional clock construction practices used for centuries.
Improved reliability
Screws provide a more secure and long‑lasting attachment than adhesive tape.
Flush fit maintained
Mechanical fastening ensures the dial plate sits properly without affecting the calendar hand.
Reversible and serviceable
Screws allow future removal without damaging the dial plate or case.
