wooden geared clock
Hi, I found this web site www.woodenclocks.co.uk/index.htm offering free plans for wooden geared clocks. If you look up the site it has 4 clocks available,I choose the plans for clock #1
As I had not attempted anything like this before,the first job was to make indexing jigs to fit the rear of a vicmark chuck,for the spacing of the teeth.
Cutting of the teeth was with a small router (gmc) fitted to a slide controlled by a fulcrum lever attached to the lathe bed.
Cutters were ground from 1/4 inch drill bits,as each size wheel has different shaped teeth. All measurments must be accurate to a fraction of millemetre.
The frame and axles were straight forward in construction.
Modifications had to be made to the winding gears,ratchet,timing wheel and pallets,to get it ticking.
As of today it is loosing about 1 minute in 4 hours,adjustment of the pendulum is still being done.
I used kiln dried redgum (very fine grain )for the gears and axles ,ash for the rest.
No photos available until I get some one with more computor knowledge than I have to post some pics.
Have a good Australia Day

I have made another clock,this one has Satin Box gears with Blackwood frame [case]. The running time is about 27 hours with variation of about one minute,depending on tempreture and humidity. As I have another one under construction ,would any members put a figure on it to sell on Ebay. I hope the next model will run for at least 48 -49 hours.
now to try some attachments, the first time.

Absolutely wonderful!!
I can't imagine ever having the skill to produce such an object. As for price, I don't think anyone would pay enough for it to compensate for the hours of work involved.

Wow! Looking at the plans - great site.
Irrespective of the plans (that look excellent), translating them into an actual object is an amazing combination of skill, and patience.
I take my hat off to you.
BTW - price. Don't think eBay is going to get the price you deserve. I have no idea how long something like this would take, but for an uneducated guess on value - $1000.
Instead, I'd make up 1/2 a dozen or so, then find a gallery and have them as an exhibition where people can buy the works. Given you are in Geelong, you are in a reasonable location for those sorts of galleries. There is one in Williamstown that I have used in the past for a photographic exhibition. They were a bit expensive to exhibit, so I'd find somewhere prepared to work with you.
Let us know when it is on - it'd be worth the trip to see these clocks in person!
PPS - I assume that you have talked to the owner of the website, as he does state the plans are given for personal use only - I guess you need to actually buy the plans for commercial ventures."Clear, Ease Springs"

Hey
Great work
Am I reading the site correctly. You attach the stencil of the gear to the timber and send it to a cnc shop or Dr Evil if he is nearby for him to cut with his "laser"?:confused:
this could be fun

Hi Stuart
The clock will be on show at the Barwon Valley Woodwrights Expo november 4 & 5 here in Geelong.
The works of the clock are my own design , layout and construction. Only information used from other plans was the number of teeth on each cog.
Dazzler, all gears were made on the lathe with router attachment.
see first post on this thread.
Will try for some phohos of indexing jig and lathe attachments.

Suberb work, nine. Wish I could see them in the flesh. I once built a wooden clock from a kit, and can only imagine the intricacies involved in making all the gears, escapements, etc. so precisely. I believe John Harrison (of Longitude fame) was able to get very accurate and near frictionless wooden clocks by using mixtures of different timbers in his gearing to compensate for wood movement. One of them is still working isn't it? Not bad after almost 300 years.
Those are my principles, and if you don't like them . . . well, I have others.

That is one beautiful piece Nine! Very classy! I've seen some similar clocks done by a bloke in the Coffs Harbour WW club and I seem to remember price tags of over $2000. Don't undercut yourself on it - it's gotta be worth more than $1000. Personally, I couldn't bear to part with something like that unless it was staying in the family so I could visit it.
