This is Part III and the final part of a three part series on my first venture into veneer repair on an antique clock. Prior to beginning this project I spent many hours researching veneer repair, watching YouTube videos and seeking advice from my knowledgeable colleagues at NAWCC.
A recent acquisition, this is an 8-day Seth Thomas column and cornice time and strike shelf clock with sleigh front. It has a Plymouth (Hollow) lyre movement with a Thomaston Conn. label which means that the clock was made shortly before the incorporation of Thomaston in the early 1870s.
I assessed this clock in Part I and described the steps in preparation for the veneer repair. In Part II I described the process of applying veneer. Part III concerns the final finishing. Once the case work is complete I will focus my attention on servicing the movement, addressing the dial issues and replacing the clear glass with a floral pattern in the upper tablet.
The lighter coloured sections in the next photo are new veneer pieces. New veneer is found on the top of the cornice, the left cornice base, the right column support and sections of the bottom base.
Finishing is the final phase of this project. In many respects this can be the most challenging phase of the project because once the hard work of applying veneer is complete the job means nothing if the new veneer does not match the old veneer. Although it can never be a perfect match the goal is to come as close as possible.
One finish seemed to stand out above the others
I conducted an experiment on leftover Brazilian Rosewood.
I selected three stains/finishes, Minwax Rosewood gel stain, Wipe-On Polyurethane satin clear coat and yellow shellac. I utilized various light sources to see the effect colour temperature had on the results and came to the conclusion that there was one finish that seemed to stand out above the others.
In the photo below there are three swatches on a piece of leftover veneer; Rosewood gel stain on the left, Wipe-On Polyurethane in the middle and on the right is yellow Shellac. Wipe-On Poly initially struck me as the best of the three; it is subtle while bringing out the character of the Brazilian Rosewood veneer while keeping that “aged” look but it is too muted. Rosewood gel is reddish and quite dark and looked very striking compared to the original Rosewood.
I concluded that yellow shellac was the best choice. Shellac darkens the veneer and accentuates the red tones nicely. Shellac would have been been the original finish when the clock was made and it is still the finish of choice today.
Although veneering is a challenge, it is very rewarding work and I eagerly await my next project
Although veneering is a challenge, it is very rewarding work and I eagerly awaiting my next veneering project.
With the veneer repairs completed and the movement serviced there is still work to be done on this clock. I have decided that the gesso columns will stay as-is. Next is perfecting a tablet design for the access door to replace the clear glass, and finally, making a decision regarding the dial face; whether to leave as-is, find a suitable replacement or buy a new one from a clock supplier.
- Allot a significant portion of time for the project, it is time-consuming and meticulous.
- For an authentic repair hide glue must be used; avoid white or yellow carpenters glue though I would think there are rare times when it would be considered.
- Hide glue:
- must be a certain consistency to work properly. It should drip off the brush like honey. My hide glue was too thin at the start of the project.
- will last a while in the fridge. Don’t cap the glue while it cools; condensation will hasten mold growth
- Stay away from plastic based modern stains and finishes and go with shellac or any finish that would have been used at the time.
- Some use filler to smooth the gaps between pieces of veneer, I did not use filler for this project; it is something I might consider next time.
- A light sanding of the veneer is all you need, aggressive sanding will destroy the veneer (lesson learned).
- Apply painters tape on the veneer before cutting; doing so eliminates ripping and tearing.
- Use a sharp hobby knife
- In future I would consider replacing larger sections rather than a patchwork of small pieces though that largely depends on how much veneer you have to work with.
- Clamps are essential. Get various sizes of clamps and use wax paper between the clamp and the veneer, you will thank me!
- Leave the area clamped for 24 hours. Although hide glue bonds quickly clamping for a day will ensure maximum adhesion.
This was a great project and I am confident that my next veneer project will be even better. Time, patience and perseverance are keys to a successful veneering project.
