Introduction: How to Make a Wooden Clock. ***Update for All Who Asked***

Picture of How to Make a Wooden Clock. ***Update for All Who Asked***

I was given the plans for this clock which were originally drawn up by Nick Andronis by a friend quite a while ago. I first set out on this journey to build a clock only to realize how little I knew about clocks or wood.
The inspiration clock had a hour/minute and seconds dial with a short run time. What I wanted was a clock with a symmetrical dial and a day of the month dial. The run time was increased by maximizing the weight run length and minimizing the bush bearing friction. The original run time design was seven days but could not be achieved with wooden bush bearings.

Step 1: Prepare to Become Needy

Things you will need:

Wood (at least two different types if you want a contrast.) Yes I know this should be a no brainer. However, you must remember that every piece will require at least some material. Wood is not a cheap medium to work in and you WILL make mistakes. Do not get chemically treated, unseasoned or green wood or expect to walk into your backyard for trees.

Tape measure: Prepare to measure three times if not more and cut once. Again, have extra wood.

Micrometer. Don't be cheap, buy a professional, digital metal micrometer. You'll thank me later.

Paper: I went to a local art store and bought two rolls of kids art paper, it is good for calculations, lists, templates and beating on things during the occasional temper tantrum.

Glue: Don't skimp, buy wood glue or something similar. Something that you can wipe off if/ when you make mistakes.

Wood clamps: Buy at least 4 in several sizes, they don't wear out easily but you never seem to have enough.

Stain or linseed oil: Decide what you are going to use, buy a gallon and a half, mix it together in a 5 gallon bucket before use, the batches don't always match.

Shellac, lacquer or sealant: Bring out the shine in your work.

Sandpaper: Get 100-1400 wet/ dry, a sanding block, an electric sander and be prepared to take a lot of time.

Drill press: The parts have to be precise or they won't fit or work.

Hand drill: Some pieces are too large or small to hold on a press.

Table, miter or chop saw: For rough, straight cuts or long lengths.

Band or Jig saw: bigger radius cuts, circles or shapes can be achieved with this.

Hack saw: Little, tiny curves cannot be cut precisely enough on a band saw.

000 Steel Wool: if you sand with this last you will get a super shiny finish.

Lead: This hazardous material is used for the counter weights. I found mine at a scrap yard and they were more than happy to give it to me. Worse comes to worse you could always melt down old tire weights. It will have to be a lot of them, and please... No stealing. Steel can also be used but you will have to have it machined.

Step 2: I've Got Wood!

Picture of I've Got Wood!

Hardwoods are in a group of trees that have broad leaves, produce a fruit or nut, and generally go dormant in the winter. The United State's have temperate climates produce forests with hundreds of various hardwood trees that share certain biological characteristics. Although oak, maple and cherry are all hardwoods, they are different species. All together the hardwood species represent 40 percent of trees here.

Taking all of this into consideration I decided to use cherry as my primary and red oak as the accent pieces. Well, that and the cost of materials.

You need to really look at all factors before deciding for your own project.

Step 3: Size Matters

Picture of Size Matters

The size of the clock was determined by the largest piece of wood that could purchase. The size of every clock component is a ratio of the escapement diameter. The metric units are considerably easier to measure than the standard measurements. The 180mm diameter by 4mm thick escapement required a dimensional stability of less than 0.5mm.
To minimize warping the escapement was solved by polishing the cherrywood with a round sanding disk and heating the wood until the resin melted and the moisture evaporated. Heating the wood also increased the hardness and the contrast in the wood grain. By clamping the wood and allowing it to cool over several days the wood will stabilize and stops warping. This procedure must be repeated in order to thickness the escapement down from 8mm to 4mm in 1mm steps. To relieve internal stresses the escapement must be roughed out before this. Once the required thickness has been achieved then the escapement hammers and ribs can be finished off.
I found a local wood kiln, which is what I recommend unless you want to build one.

****Word of warning: do not try to do this over an open flame or in your oven. The wood smells awesome, the beat down your spouse will issue is not. These are written in blood! Learn from my mistakes people!****

Step 4: Three Part Harmony

Picture of Three Part Harmony

One of the lessons learnt from complex engineering systems is to build the most difficult bit first.
If you cannot build a clock with only a second hand then there was no point continuing with the project.
A three component clock is assembled from the escapement, simple rocker and a pendulum rod.
Calculations indicate that a two second time constant required a 1 meter pendulum. So in theory the clock should work if the time constant of a pendulum is a function of the distance between the pivot point and the center of gravity. The mass of pendulum rod shifts the center of gravity closer to the pivot point.

Step 5: Pretty

These pieces came together.

Step 6: Gears

Picture of Gears

A computer laser printer was used to generate gear templates that were printed on adhesive paper. Then I drilled out the center of each gear using standard drill bits and finished each by hand. ***Warning*** Drilling straight hole across the grain is difficult. The hole centers were marked with a fine cross on the laser printer templates. I first marked the centers of each hole with a pick then used that as my holes beginning. Gears were clamped to a table vice on the drill press and then drilled with a 3mm drill bit. Then I swapped the fine drill bit for the correct size drill bit. This process produced precision holes but was very labor intensive.

Step 7: How Do I Look?

Step 8: Separation Anxiety

I made the face and encasement pieces in many parts which I then glued together. Again, labor intensive but worth it.

Step 9: Done and Done

Picture of Done and Done

Large pieces of quality cherrywood were expensive so the clock dials had to be manufactured by laminating 12 pieces of wood. Looks easier than it was.

Step 10: It's the Little Things

Picture of It's the Little Things

There are many, many carriers, bolts, nuts and pins. Each made by hand.

Step 11: Now You See Me.

Picture of Now You See Me.

Remember, test fit everything. The inside before I assembled everything.

Step 12: Weighty

Picture of Weighty

The weights have to be figured or your clock won't function properly. There are websites to help you with this.

Step 13: Show and Tell

Here Are The Finished Lead And Holders

Step 14: Reunited

Assemble all of the upper workings and case.

Step 15: And It Feels So Good

Picture of And It Feels So Good

Here are the pictures of my clockwork.

Step 16: Supporting Cast

Picture of Supporting Cast

The support structure had to be made from several pieces as well. Align each leg and make sure to level them.

Step 17: Legs

Picture of Legs

Assemble the support cradle make sure to polish and seal it. Make sure it is level.

Step 18: Mounting

Picture of Mounting

Mount the top on the base. Make sure not to over tighten the support.

Step 19: Done

Picture of Done

Lace through the drive weights and adjust the clock time constant. This process took forever, be prepared to tweet and adjust a lot.
The clearance between the gear teeth had to be adjusted to allow the clock to run free. Slight density differences of wood made the load unbalanced. The drive shafts were not at right angles to the gear so the clock would stop every few hours. All of this caused the clock to stop at certain times of the day.
The gears can be balanced by spinning the gears in the clock frame. If the gear stopped in the same place then wood should be removed from the bottom of the gear.
The time constant of the clock was finally set by adjusting the pendulum weight screw. Once the clock time constant is set the clock will run for two days with an accuracy of better than five seconds per day.

Enjoy.

Beautiful work. I plan to make mine into a wall hanging clock, although I must admit that the pedestal is quite attractive.

Do you plan on posting better images of the plans? i suggest. PDF so that the plans can be. printed to actual 1:1 size to create gear cutting templates.

Great job.

Cheers

eric53 (author)alcurb2015-10-25

When you download the pdf's from

http://members.iinet.net.au/~andronis/ set your printer to print custom - 100% and you will get a 1:1 image. As Nick suggests, print the images onto self adhesive paper (if you are using scroll saw)

mitchellguyon (author)alcurb2014-11-15

Thank you. I will be posting full PDFs as soon as I figure out how.

torrentmt (author)mitchellguyon2014-11-16

Hi impressive !

Can you post the dxf or dwg ? or any origianl file. So I can import the part in the CAD software. I've access to a cnc laser cutting machine. I plan to build my clock.

thanks in advance

Is it possible to get better pictures that can be used for templates? these are too small and when blown up are completely unreadable.

the plans are now included in the instructions

eric53 (author)mitchellguyon2015-10-25

The pictures you copied off Nick Andronis' web page are all upside down

If you go to this link

http://members.iinet.net.au/~andronis/

you can download the full set of .pdf's about 120 pages+/- .If you live in high humidity areas don't build this clock out of wood, use acrylic or perspex

Certainly

Great Job!
You Sir,
Are an inspiration to other iblers.

jeanluc83 (author)2014-11-18

Great job! I have had those same plans for about 10 years now but one day...

My only comment is that you should give credit to the original author of the plans.

mitchellguyon (author)jeanluc832014-11-21

Thank you for your suggestion, I took it to heart and added the original plans artists name.

Wow!....Amazing. Very nice work!

Jonnis shed stuff (author)2014-11-14

i've been working with wood my whole life i'm now a cabinet maker and woodturner. but this is beautiful! very impressed!!

CProkopp (author)2014-11-14

Very cool. I've built many wooden-wheeled clocks, and love doing it. Years ago, I downloaded these plans, but haven't gotten around to starting on the project. My plan is to use Baltic birch plywood for all of the wheels, as it's more dimensionally stable than using plain lumber. The framework will be oak or mesquite. For the pivot holes, I'll use brass or nylon bushings.

It's nice to see that smeone has actually built this piece. Thanks for sharing your experience!

winnfamily (author)2014-11-14

Wow nothing but wow
Amazing piece of machinery
I have been a finish carpenter and have worked with Wood for the past 40 years
But your skill level constructing this clock well exceeds anything I ever thought I could do
Such a challenge cannot be ignored. As I walk off to the workshop
Thank you for the time it took you to share all this information

mitchellguyon (author)winnfamily2014-11-14

Wow, thank you, that is a huge compliment!

Wired_Mist (author)2014-11-14

Incredible ! A piece of art like that needs a glass case and a security guard! did you use a laser cutter for the basic shape or gears?

mitchellguyon (author)Wired_Mist2014-11-14

Now I actually do not own a laser cutter (I wish) It was done with hand and electric tools.
