Dugena Clock Dilemma

-
Dugena mantle clock
I bought this Dugena mantle clock for $30CDN. The owner assured me that it was an old clock and not to expect it to be perfect. It certainly is not perfect. It is a 2-train German made Bim-Bam clock. There is a strike and a time train. The strike train is off because it will strike incessantly. No doubt something is either worn, broken or misaligned.

Movement for Dugena clock
My first attempt at cleaning it involved taking out the movement and placing it in an ammonia bath with some Murphy's soap. The net result is that once I dried it off it was no different than before. The clock has a balance wheel escarpment and it looks as though the spring might be a little weak because the wheel does not spin more than 180 degrees. Bottom line, it needs to be taken apart and cleaned properly.

Given that I have never taken a clock apart it looks like a daunting task for a couple of reasons. One, I do not have the right tools and two, if I took it apart there is an excellent chance that I would not get it together correctly and working as it should.

So, I have a couple of choices. I can work on the movement and get it to work as it should after a decent cleaning or use the movement as a test bed and simply buy a replacement movement like the one in the last photo. The replacement movement is $128CDN for a pendulum movement or $198CDN for a balance wheel escarpment.

Now I could get a replacement balance wheel but at this point I don't even know if that is the problem. So, what to do.

If I got a new movement the clock would likely run trouble-free for years. It would mean bringing the case up to showroom condition however. At this point the case is in pretty good condition for it's age and it would not take much to make a few more cosmetic improvements to make it quite presentable but obviously not new looking. So, that is my dilemma.

Leave a comment for me if you have any advice.

Seth Thomas Round Top Mantel Clock

Seth Thomas Dome clock I wrote about this clock a few months back and at that time it was only running for a couple of days. I was pretty happy with my purchase since I had picked it up at a junk / antique store just about a 1/2 hours drive from here. It has, in fact been running wonderfully for several months now. It's a bit idiosyncratic in that despite being an 8-day clock it does not like being wound right down because the count wheel for the strike gets confused and strikes the hour on the half hour instead. Could be it needs some adjustment. Keeping it wound without it stopping has proven to work. It also ticks quite loudly but it is in our dining room and certainly not intrusive in that location. It has been oiled and seems to runs just fine. The walnut case is in excellent condition and a good rubbing with Murphy's Soap has virtually restored the cabinet. I make it a point not to redo the clock finish if it has minor nicks and scratches. I have an assortment of ...

Seth Thomas Gothic Beehive Mantle Clock

Seth Thomas Beehive Mantle clock circa 1928 This is a Seth Thomas Gothic beehive mantle clock. The face has Henry Birks & Sons inscribed on it and obviously the company contracted the clock out to Seth Thomas at that time. The movement is an 89AL which was used in a variety of clock between 1922 and 1928 so I would put this clock at around the 1928 period. There is a little plaque inside the back access door giving the reseller location which in this case is Amherst, Nova Scotia. I has been running all day now and I am just waiting to see whether it gains or loses time. I will know in about 24 hours. The beat is good but the clock chimes the hours on the half hour which is obviously not supposed to happen. It means a minute hand pin adjustment once I know that the clock can run steadily. As is typical of these old clocks there was a lot of dirt and grime on the finish. Rather than take the dramatic step of refinishing the clock it is far easier to take a good cleaner, in my...

Photography Rant – Is It A Rant Or Just Some Observations?

Panasonic G6 with 45-175mm zoom On my last holiday trips outside this country I was surprised to see so many people using cell phones to take photos. Perhaps I shouldn’t be surprised, the world of technology is changing and changing very rapidly. I was also equally surprised to see so few people using cameras and most of what I saw were larger DSLRs (I am a mirrorless user myself). Some were even using their iPad which in and of itself is rather amusing to watch. Cell phones have virtually hosed the lower digital camera market and must be a blow to the bottom line of camera companies who saw much of their profit in these small entry level cameras go out the window in recent years. So, along comes the cell phone, the new Kodak Instamatic.  If you are into a phone contract as most people are you might as well take advantage of as many features of the phone as you can and that includes taking photos and immediately posting them for all the world to see. Cell phones have o...
