This is a Clayton Boyer designed wooden clock. I just finished. I was going to give it to my son and his wife. It is kind of plain. I am going to build another using some hardwoods (domestic and exotic) to add some color. This is all out of Baltic Birch plywood.
This is the second wooden geared clock I’ve built. The lessons learned on the first really helped on this one.

Very nice job—this is one of those things on my “bucket list,” but will probably stay there for awhile, at least until other things are done. Thanks for sharing.

Bruce, great job!! Cutting the teeth on all of those gears can get tedious but you conquered :) Your choice of Baltic birch for your first clock project was probably a good one.

Nice clock.

You can add some beautiful color and get rid of any plainness you see with dyes or veneers. Baltic birch is an ideal substrate for either the dyes or the veneers. You could add color to any of the components, but use a bit of caution with those parts that require close tolerances like the gears.

By the way, what name did Clayton gave to this clock, and how is this one powered?

Thanks for sharing it.

It the Toucan and it’s electromagnetically powered. When I build the next one the frame and gears will be baltic birch I will probably stain the frame but leave the gears natural, then use hardwoods for the base ,face ring and some of the other parts.

I love the walking escapement on that one. One of these days, I’ll build one of Clayton’s designs….

Nice job! I designed and built a similar clock. I’m curious about the Toucan escapement – it appears that if the pendulum swing is too small or too large, the escapement won’t work – can you comment on that? I would also like to compare notes on the drive. I use a more complicated circuit with a microcontroller, with the advantage that it regulates the pendulum and keeps accurate time.

You’re right about the escapement and pendulum swing. The cam is adjustable and will compensate for some excess pendulum swing.
The pendulum has a fixed bob that you can see in picture 5 with a fixed magnet mounted in it and then it has an adjustable bob partway up the pendulum that you screw up or down for adjustment. I currently have it adjusted to where it is gaining less than a minute in 24 hours. It will take a while but should have it to where it is very accurate.
The drive on this consists of 2 windings an inner sensing coil and an outer impulse coil, an NPN transistor, a diode, and a 9 volt DC power supply.
That was probably the hardest part winding the coil to my standards and soldering the components in.
I may have seen your clock online. When I was looking at this clock I was also looking at other electromagnetic drive clocks and did find one that used a microcontroller to regulate the clock.

Thanks Bruce! I had trouble with the varying swing of the pendulum causing errors at first, but evolved the design to a cam on the pendulum pivot that results in limited movement no matter the angle of swing. I started with a two-transistor single coil circuit but it wasn’t reliable for me so I came up with two other designs, one with the microcontroller. Both are single coil. I have seen one clock where a microcontroller was used to trigger the coil current, but it did not regulate the pendulum. If you are able, please post or send me a link to the one that you found.

I’m working on my next clock which will have a second hand. Someone adapted Toucan for that, but I’m planning a bit different approach.

Very nice job. it should look even more beautiful using contrasting species of wood. Nice Work, Keep it up.

Nice clock Bruce!

I think the Tucan is next on my list. I have already built a Simplicity ( ). Making a clock is a lot of fun.

I am building another Toucan right now using some different woods. I think my next one will be either the simplicity or the 6. I need to talk to my daughter se which she likes best.

I have never built a wood gear clock; but I have been looking at them the past few days. It was nice to find this old thread at LJ. Answered a number of my concerns about the drive mechanism. I have now put the Toucan plan on my Christmas list. Looking forward to building this marvelous little gem.
