Waterbury Miniature Ogee Clock - Part 1

I have had this clock for long enough that I seem to have lost the paper work for it. I bought it as an empty case. Actually I just checked a purchase list, and I bought it in summer 2006! At the time I wanted a miniature ogee clock, and I believe I may have had a spare Waterbury shelf clock movement for it. I had only paid 34$ USD for the case, plus shipping. Not such a great bargain based on today's prices, but mini ogees back then would normally sell for 200-300$ USD.

Anyhow, the case had lots of loose or flaked-off veneer, and it needed work.

A few years ago (early 2015), while I was working on a whole bunch of different veneering repairs (http://jcclocks.blogspot.ca/2015/02/veneer-patching-extravaganza.html) I had glued down the loose sections of the veneer for this case.

PC240144

Then a few weeks ago I finished the rest of the repairs. This involved gluing another big section that popped off on the door, and patching the missing sections on the veneer. Before I start showing the patches, this is how the clock looked after the 2015 repairs.

P5130037

The edge uses curved veneer, so I used some of my pre-curved mahogany veneer stock for the patches. Any of the small chips, I did not use wood, I used putty. This is especially good for small chips along the bottom where the veneer is already really dark.

P5150040

Putty-filled repairs:

P5150041

Veneer patch on the corner, putty on the chips.

P5150042

Again, a mix of veneer and putty. Keep in mind that any putty repairs must be touched-up with paint.

Top right corner:

All the repairs and patches before stain, paint, and touch-ups.

P5150047

Stain is applied first. Depending what stains you use, how much sanding you did, and what wood was used, the colour may be too light or too dark. It's kind of difficult to predict how certain spots will turn out. For the painted putty areas, those mainly work best on very dark finishes. This case is quite dark brown, so it's pretty forgiving to mix any "close enough" shade of blackish-brownish-reddish paint, and blend that in. I use one or two small paint brushes, but a lot of it is creative finger painting. Water is used to add transparency.

P5150048

Bottom chips after painting. There are 4 decent sized chips, and a veneer patch in the left corner.

P5150049

All the repairs and patches were then coated in several layers of orange shellac. The entire case was then buffed down with #0000 steel wool lubricated in dark paste wax. The wax is left to dry and go dull before polishing.

This shows the wax-buffed case just before polishing (so looking quite dull overall).

Here's just a small bit once you start buffing the wax.

Hopefully I can photograph the finished case soon.

Rosewood Seth Thomas (Thomaston) Ogee Clock - Part 3

I have yet to finish this series (as well as a few others). This is part 3, which covers some of the final details of the restoration.

Part 1: http://jcclocks.blogspot.ca/2016/02/rosewood-seth-thomas-thomaston-ogee.html
Part 2: http://jcclocks.blogspot.ca/2017/04/rosewood-seth-thomas-thomaston-ogee.html

In this part, I tacked an extremely unusual problem. For whatever reason, this ogee clock was NOT BUILT CORRECTLY. When I was finished working on the movement, I had trouble fitting it into the case properly, especially with respects to the dial. The hands would not clear the dial. This is a paper thin zinc sheet dial with a raised ring (which is standard on ALL older Seth Thomas clocks). The hands would not clear even in the centre (flat) portion of the dial.

I decided to take out the runners and set up the movement clearances correctly outside of the case.

P2030527

In normal cases, the winding squares should be just a hair below the dial surface.

Playing around with tongue depressors (or popsickle sticks) I found that the movement would need to be raised at least 1/4 inch. HOWEVER, with the movement moved forward this far, the hand shaft would hit the glass, and you wouldn't be able to close the door.

P2030530

Curiously, the seatboard had already been partially shimmed on the back side.

P2030531

The real problem, however, was that the depth of the rails was wrong. I could see that the dial mounting tabs had actually gouged into the back of the door (the door was closing tightly onto the pins), because they were too far forward. Normally these rails are about 2 1/4" to 2 3/8" deep. These were almost 2 5/8". Nearly 3/8" too deep.

P2030532

P2030535

So the solution was simple. Trim the side rails (on the back) and reinstall them. I did not cut them down the full 3/8". I trimmed them only by how much I needed to shim-up the movement (the amount of pospickle sticks), so about 1/4 inch.

Once that was done, everything went back together just fine (I used old and new square nails), and the dial and movement fit perfectly, with proper clearance for the hands, and perfect clearance for the door (the door is no longer rubbing up onto the dial or pins).

P2030537

I still need to post multiple photos of a half dozen restored or repainted dials. This was the fully repainted dial (before antiquing).

P2030539

After antiquing:

P2070553

Another case repair that I needed to do was to repair the worn out hole for the movement hold-down. The chip-out was puttied, and the area was colour-matched to hide the repair.

P2130588

Hole patch from the interior. I used poplar for the plug since it will last a bit longer than pine (which is softer).

P2130589

P2130590

The final part will just be final photos and before and afters of the clock. Not too sure when I'll post those, but you can see most of the completed clock in Part 2.

Antique Mirror Repair

This was a really beautiful antique mirror with beveled glass that I picked up at a Flea Market. I think I paid 10$ for it. The mirror was in perfect shape, but the frame had a few big chips in the curved veneer. I assume that this mirror is from around 1880, but it could be slightly older or newer. Definitely older than 1900.

For probably close to a year it's been patiently sitting and waiting to be repaired. I'm not even sure where I want to hang it yet, but since I've been doing a LOT of veneer patching on clocks lately, I decided to do the repair while I had fresh hide glue on hand.

As purchased:

P5130032

All 4 corners had chips, but the real issues were with this one bottom corner. The other corners had very tiny chips (I didn't photograph them, they were only about 1/8" wide).

Because of how this corner was broken, I would either need to make two striped patches (which would be tricky and possibly ugly as a repair), or remove the entire corner section, and install a larger patch. This is what I did. With the wood veneer that I removed, I was able to patch all the other 3 corners, so those repairs ended up being virtually invisible.

P5130033

P5130034

Corner section removed. The mesh is something new to me. I'm not sure exactly what it was for, but it seems original and I left it there. Part of the veneer was loose past where I cut it, so hide glue was brushed/pushed under there.

P5130035

The wood was a bit odd. It looks a lot like walnut, but I was fairly sure it was actually mahogany, so I used mahogany for the patch. The wood had to be pre-curved around a form (you just wet the veneer in hot water, clamp it around a curve that is tighter/smaller than what you need, and leave it to fully dry). Once it was glued down (using hide glue and painter's tape as clamps) the edges were trimmed, sanded, and the repairs were stained as needed.

P5130039

The finish on the mirror was kind of dry and flaky, so I scrubbed down the finish lightly with steel wool and alcohol, and then I added a few thin coats of shellac over the repairs and then over the whole frame. This was then buffed down and wax polished with steel wool (#0000) and dark tinted wax.

P5310082

The colour match on the patch is not a 100% perfect match because the old veneer was somewhat sun bleached. It blends in fairly well, and it's only a simple mirror, so not a museum piece.

P5310083

All these techniques can be used to repair clock cases.

Antique Hopf (Repro) Violin Restoration

I recently finished the restoration of my Hopf violin. I just have to get it set up and strung. I thought I would share the before and after photos. This is not clock related, but many of the techniques and materials are the same as those that I use in clock repair: hide glue, shellac, veneer tools such as small saws, small clamps, sand papers, etc.

This is an antique violin marked "HOPF" on the back, but it's generally referred to as a fake Hopf violin (in the same way that you can buy a Stradivarius copy today). The real ones made by this 17th century family are marked only on the interior, and they are far more valuable. This one is somewhat poorly built (with no interior corner blocks), and there are several other small issues with it, such as a curve to the neck, and very poorly (crookedly) drilled peg holes. Another dead giveaway that this was originally a cheap German made violin is the fact that the fittings on it were made from cheap woods. I'll repeat this with the accompanying photos below, but the fingerboard was PINE (which is absolute garbage because it needs to be a hardwood at the bare minimum - ebony being the preferred choice), and the pegs (the one original one that was left) and the tailpiece were maple stained/painted black.

All that being said, it's still an OLD violin, probably from around 1900. This is the kind of violin you are likely to come across if your uncle/father/grandmother etc. happens to have an old violin lying around somewhere. Some are better than others, but generally all old violins will have a decent sound because the wood has aged, they've gathered patina, they were played frequently, and most of all: they were hand made. The variations in thickness, as well as the hand varnishing both add significantly to the quality/desirability/sound of a violin. Modern mass produced violins are cut by CNC and because they are too perfect/precise, they tend to have a certain generic sound to them that violin experts can pick up immediately. My ears aren't that well trained. Once this one is playable, it should have a fairly mellow sound.

Anyhow, I picked up this poor little thing all battered and abused from a local thrift shop for 25$ CAD + taxes. I'd say that's a pretty darn good price. It came with a pretty beat-up/ruined bow, which I might also try to repair.

P9120199

One-piece flame maple back with a two-tone colour.

P9120202

The top was badly gummed-up and dirty. The area where the bridge sat was also very badly scratched down to bare wood.

P9120211

The tailpiece had also scratched up the top.

P9120217

P9130237

The SEVERELY worn down pine fingerboard. Obviously this instrument was played a LOT.

P9130245

This was after I repaired/blended and touched-up the top. There were also wear marks along the edges of the top. It's not perfect, and there are a few blotchy areas, but I wanted to preserve as much of the character/patina as possible.

P9130249

I did not do very much with the back. Mostly just a cleaning and wax polish.

P9130250

The top had at least two very bad cracks in it (which eventually ended up being 4 cracks), so I had to separate it to repair it. You can see how there are no corner blocks in the pointed corners.

P9140254

I discovered a very alarming problem with the violin's top, and I was very glad that I decided to remove the top. The entire bass bar was split and coming loose from the top. There was also a crack along the edge (where the bridge sits).

P9140257

Interior view. No names, inscriptions, or repair dates. Just dust.

P9140258

Some of the top repairs were easier to glue than others.

P9140275

I did look at several violin repair tutorials and fixed it in the normal acceptable current method, which is to install small patch blocks (cross grain glued) made from cedar, and then pared down thin. I also had to slightly sand and re-shape the glue-side of the bass bar for a tighter fit.

P9160278

Here were the cheap fittings. Painted pine fingerboard, and maple tailpiece stained to look like ebony.

A quick note: when it comes to violins, there doesn't seem to be any real impact what fittings you put on it. Generally it needs an ebony fingerboard, nut, and saddle, but the other fittings are to your choice. The pegs, tailpiece, and chin rest can be any wood you like (Rosewood, Boxwood, and other exotic woods are popular). Some can be carved, or have fancy inlays of shells, ivory or metals. Changing the fittings doesn't seem to affect the value of a violin. For this one, I went through a lot of trouble to track down plain ebony fittings (no inlay or anything, just very plain black ebony).

P9160283

P9160284

Before and after:

P9120199b

The old pegs were a complete mess. Someone had hand carved some very crude oak pegs for this and they did not work or look good. When I fit the new pegs, I had to enlarge the worn out holes slightly, so I tried to straighten the pegs as much as possible. Most are good, but the bottom one is still quite crooked. Also note the nut (before and after). Yikes!

P9120215

The saddle that was there was probably a replacement, but it was very badly carved. It didn't need to be replaced, but I did clean it up and sand it significantly. I had a new end button in my new parts, but I chose to keep the old one (this is the only part of the old fittings I kept because it was actually ebony).

P9130236

The top had two small chunks broken from the edge that I was able to patch. One is nearly invisible, but the other one shows a little bit.

P9130238

A close up of just the pegbox:

That's it. I may post a photo of it again once it's strung.
