Kirt's Lorraine Grandmother Clock Project

The hickory was bought from Summit Hardwoods, just a few miles south of Erie, PA. Thus far I have cut out most of the rectangular blanks. Finally, the process of squaring everything and exacting the dimensions, then the detailed shaping, drilling, routing, sanding, etc., has paid off in the form of a beautiful, classic grandmother clock.

Although I enjoy the building and finishing process, I can't wait to hear the tick-tock of the weight-driven clockworks, and the hourly chimes. My obsession with the passage of time is pacified for the time being with a refinished antique wall regulator, but this is my piece pièce de résistance.

The instructions and drawings provided on the plans are excellent, but as the old adage goes, a picture is worth a thousand words (not sure how many drawings a picture is worth, though). There have been a couple instances so far where the order of operations would be better with a couple steps changed. One example is where milling the 1/4" cove in the Hood's arched piece (H-8) over the door is necessary prior to hinging the door because otherwise the door cannot swing shut. Another is that I decided to glue the crown pieces directly to the hood rather than build the crown assembly separately and then screw it to the hood. There is also the case in Step 28 where the wrong edge of Hood bottom is indicated on the plans.

Latest update August 10, 2013

The Lorraine Grandmother Clock project is officially complete! All four 1/8" thick glass panels were cut by Schaal Glass Company here in Erie, PA. They did a great job with the arched piece that goes in the door for the dial. If I had though it out before-hand, I would have modified the plans to use just a simple arch to make glass cutting simpler (and less expensive). There would still be a shoulder region per plans when viewed from the front, but the inset for the glass in the back of the door would have just an arch from one side to the other. A complete set of photos of the finished clock will be posted soon. Here is a short video tour of the completed Lorraine Grandmother Clock!

July 27, 2013 Update

The Lorraine Grandmother Clock is complete and has been fully operational of of July 27, 2013! The only thing left to do is install the glass panels, but I'm waiting to have them cut. Doing a complete mock-up of the mounting and fitting prior to finishing made for very quick work installing all the clockworks components and panels. A very slight adjustment of the chime hammers was needed, but that's it. I pulled the pendulum to the side and let go, and it's been ticking away ever since. Thus far it appears to be keeping perfect time. The moon dial has been set for today's moon phase, so it will be interesting to watch it progress over the next month. planning for the clock began in November of 2009 when I purchased the plans from Klockit - about 3 years and 9 months.

Melanie did a great job filming a short video on me explaining my method for applying polyurethane without suffering the heartbreak of runs, sags, and air bubble in the finish. That is a hot topic in online forums and as you might expect, there are many opinions, often contradictory, on the best way to do it. My way has been honed over many decades and works well for me, but it might not be the best way for everyone. Melanie made a video of me talking through my process of applying the polyurethane in a manner that eliminates bubbles, sags, and runs.

Installing finial mounting stud. Put nut on finial end and use a socket to screw into wood, then screw finial onto stud. Doing so prevents potential stripping of finial threads. Use way on wood thread end to ease installation.	Using a dab of wax on screws during installation makes them much easier to install, especially in hardwood, and minimizes the potential of wringing the head off. I pre-drilled and pre-threaded every screw hole prior to finishing, but still used wax for final assembly.	Using a square screwdriver bit to adjust the friction-fit center hub of the minute hand simplifies the job

Update September 16, 2012

At long last, most of the major house projects are done so I'm finally able to get back to work on the clock! Oh, part of the delay has been due to moving to a new house in December 2010. The workshop is set up in the garage of the new house rather than in the basement as the previous one was. It's nice having an 8-foot high ceiling again. Before beginning assembly of the clock's hood (top enclosure for the works and dial), I took the time to scratch a 2" square grid pattern on the workbench surface. Dark stain was brushed into the grooves and then a couple coats of clear were sprayed over everything. This will make getting all of the clock components straight and square much easier. The clock's hood assembly is being clamped and screwed at this point. The plans don't call for glue on any of the frame joints, but I will put some on prior to final assembly of each section. Trim pieces in future steps will hide all of the screws in the frame so it will not be necessary to plug the screw heads. It has been a long time since I undertook a project like this where precision cutting and sanding is required for everything to fit properly. Buying a much better belt/disc sander has made keeping edges square and straight much easier (the old 3" model was a real piece of junk that would stall if I pushed down on the wood with too much force).

Update November 12, 2010

Well, I thought all the blanks had been cut, but after reading through all the plans pages, I found about 20 more pieces that were not shown on the main cut-out drawings. Most were pieces that had at least one dimension less than the stock 3/4", so it required running the wood across the jointer to trim it down to 1/2" or 1/4" as specified. I just bought a Craftsman 4-1/4" jointer, and man do I ever appreciate that machine! The last time I used one was in high school woodshop back in the mid 1970s.

Now that all the blank slabs have been cut and sanded to precise size, the next step is to begin doing all the mitering, jointing, routing, and assembling. I also bought a Craftsman router and router table to make the job easier. The table saw or radial arm saw could be used, but the router table setup will be much more precise when handling the relatively small pieces in the clock. Building a cabinet or bed frame would be a more appropriate size for using the saws.

Well, Melanie and I just signed a contract on a different house here in Erie, and we're due to close on it at the end of November, so unfortunately that means packing up everything and moving before getting back underway.

The house has 1,500 sq.ft. as opposed to our current 910 finished sq.ft. (plus full unfinished basement - see photos here). The new house is a split foyer type, so the workshop will be downstairs on the garage level It is about 25 years old, but in very good condition. One of the best features is that it is one of the very few panoramic views of Lake Erie, from a vantage point high on a ridge line. The only thing better would be to live right on the shore, which, of course, I cannot afford. I will post pictures later.

Whereas the workshop here is just kind of thrown together, in the new place I will build wooden work benches and tool stands permanently into the lower level, and there will be ample overhead lighting along with a distributed dust collection system - nothing too elaborate; just enough to keep from having to move the shop vac around all the time.

So please check back around the end of December 2010 for an update. Have a Happy Thanksgiving and a Merry Christmas!

Here are some of my other woodworking projects from over the years.
