Gingerbread Clock Case Repairs

These are two cases that I repaired a short while ago. They are a Waterbury Niles (the lighter walnut one) bought from a yard sale several years ago, and a New Haven "Merchant Line B" (dark oak) bought locally though Kijiji (similar to Craigslist) not long ago.

Both clock cases needed work, but both were purchased quite inexpensively. The Niles was 60$, and the Merchant Line B was 40$.

Let's start with the Niles. This was the clock as-purchased:

P6109720

Both top "horns" were broken off, the glass had been replaced (no transfer), the dial was awful, and the hands were incorrect. When I got it home I also discovered that it had been fitted with a New Haven movement. The clock is not valuable enough to spend 100$ to swap the movement for a correct Waterbury one, but I still want to fix it up as much as possible.

Because of the swapped movement, I had a very difficult time tracking down the model and maker. The clock has no label remaining (as is often the case with gingerbread clocks), so I had started my search with New Haven examples. I then switched to Ingraham, and I eventually stumbled on a match. This was very important because I did not know what the missing horns looked like.

Here's a good example of a Waterbury Niles (this one fitted with an alarm):

I have a number of different photos, some with close-ups, and I was able to use those as a pattern.

The New Haven had a broken latch, no glass, and the entire case was loose. In addition, both clock cases were missing their triangular glue blocks behind the crests. Here is the New Haven Merchant Line B as-purchased:

It looks almost like the case has been painted black, or been darkened with shoe polish, but I can assure you that even though it doesn't look quite right, the colour is 100% original.

You will have to excuse my slowly dying camera. It has a hard time focusing properly, and it's honestly on its last leg.

The Merchant Line B is a very interesting clock because the same pattern was cut in at least three different shapes with little regard to the actual pressed design. This particular clock has one of the cut designs that makes the most sense. I will eventually make a whole write-up about the clock and show off the variations once the clock is fully restored.

This clock needed the least amount of work. I took the case completely apart aside from the bracket base, and reassembled it with hide glue. I also cut, shaped, and antiqued a new latch for it. The commercially available latches NEVER fit correctly, and they rarely have the same shape. It's far easier and cheaper to just cut one from thin brass stock.

A new pine glue block was cut to match the existing shadow lines. Pine was used because the entire rear box of the clock is pine. If it had all been oak, then oak would have been used. This particular block is quite beefy and thick compared to others. They tend to be quite randomly sized, so try to match what was there.

I was working on both cases at the same time, so ignore the Niles case for now.

The glue block was then antiqued with acrylic paints to match the colour and patina of the case back and sides.

Here are the repairs to the Nile case.

To repair the horns, it was necessary to remove the top crest entirely. I passed the tips in the table saw (very carefully) to get nice straight and flat joints to glue new walnut blocks. In most cases (99% of the time) repairs are done with hide glue for reversibility, but in this case I believe I used carpenter's glue for a more permanent repair. It's up to you to decide what's appropriate during restoration work. This is a fragile area, so I wanted a very strong repair.

PB060630

The rear glue block was cut from a walnut scrap, and you can see that this one was MUCH thinner than the one on the New Haven clock.

PB060632

Using Photoshop, I took one of my source images and resized the image to "life size". I did this by cropping the image flush to the sides of the upper crest and then measuring my crest and making the image the same size. Once the photo on the computer is life size, I then overlay a custom sized grid on the image to match some graph paper. The easier way is to just print the life size photo or a cropped section of the photo to use as the pattern, but my printer isn't working. The image was just copied freehand to graph paper for my pattern. The pattern is then cut out of thin cardboard and traced onto the wood.

PB060633

A quick trim on the scroll saw finishes up most of the repair. This is the part where you need skill with your tools. The cut outs should be sawn ONLY with no sanding or corrections made to them, which means that they need to be cut accurately in one shot. I've cut thousands of patterns over the past decade and a half, so I have plenty of practice at this. If you're attempting a similar repair, have a skilled cabinetmaker cut the pattern for you. It will make a big difference. Sloppy or crooked cuts are incredibly hard to hide, and if you start to sand or file the edges, it will be very apparent in the finished repair because all these clocks were quickly cut and have rough dark edges on them.

PB060635

The way that the pressed pattern is applied also makes a big difference. An alarming number of people believe that these clocks were "hand carved" but that is very rarely the case. Some of the very early Eastlake period examples are, but they are the absolute minority. 99% of these are pressed the same way as "pressed-back chairs". The wood is basically fed into a press with a large metal punch that imprints the design into the wood. If you look carefully at the designs, you will see that the fibers of the wood are crushed and often splintered at the edges of hard lines.

For this reason, the best way to make these designs is by crushing the wood as opposed to carving it. Any number of household items can be used as punches. The simple lines on this design were made with a used slot screwdriver.

PB060636

Note the crushed fibers all look the same across the original section and the repair:

PB060637

Though additional source photos as well as faint shadow lines, I found that this model had rear braces. Apparently Waterbury must have known that these tips broke easily and these reinforcing braces were added early on.

PB060640

These are just simple walnut sticks with the ends pared down slightly.

PB060641

PB060644

The bottom corner on this clock was also separated, so I fixed that with a bit of hide glue and some clamps. This is a tricky corner to clamp, so a wooden scrap was placed along the back.

PB060645

PB060647

The finished repairs were sealed with orange shellac (no stain). The final colour matched pretty well, except that the existing walnut does have a bit of sun fading. The new repairs should eventually mellow with a bit of time.

I have no final photos of the clock yet, but I have replaced and antiqued a new Roman dial, installed a glass transfer, and changed the hands. I am quite happy with the results, and I will try to post a photo soon.

Some Artsy Photos to Pass the Time

The sun was shining through my bedroom window in such a way that the light was especially pretty. These photos were taken about a week ago, and they show a range of clocks from different countries: France, Germany, and America, and from the periods between 1840 to roughly 1910.

If you liked this, please let me know in the comments, as it's content that I can continue to add from time to time, since I love photography, and I have a lot of interesting clocks photos from the past decade of clock repair.

Scottish Longcase Clock - Repairing a Calendar Hand

This was a longcase clock that I cleaned and repaired for a client. The clock had several small problems, and it badly needed cleaning, but I wanted to show how I repaired the calendar hand. I find that a fair number of clockmakers can do simple hand repairs like this, while a lot don't. There is nothing really too difficult about these repairs, but you do need a bit of patience and a small bit of artistic talent to do a nice filing job that isn't too lumpy or crooked.

As received, the clock had the original second hand, and part of the calendar hand (the centre) with both ends poorly patched-in. The hour and minute hand are later replacements.

Before. This shows the original second hand at the top, the current calendar hand (as received, with ugly patches on both ends) and some newly cut pieces of brass for the repair. All I did was find brass sheet that was the same thickness (or close) and then trace it and cut the pattern using a jeweler's saw.

The second step is to de-solder and clean up the existing hand. If this hand did not have a tiny threaded centre, plus some decorative punch work, then I could have cut an entirely new hand, but the chances of matching the old threading are slim to none. Once the hand is ready, the new patch pieces get trimmed to fit, filed to size, and then soldered in place with two small patch pieces on the back.

I just used regular solder. There is no real need to use silver solder here.

I did not try to copy the punched design on the repaired section, but I did antique the brass to make everything blend nicely together.

Also note that the original hand is quite roughly cut, so you can get away with quite a bit of small mistakes.

I'm proud to say that the client was very happy with the repair.

PS: the taper pin in the two photos above was just a temporary one. I don't leave them that long, and the finished one was steel, not brass.
