Building a Wooden Clock
« on: May 24, 2014, 08:34:55 PM »
When I built my CNC machine last year I purchased DFX files from woodentimes online. I never looked at the files in detail, getting distracted as I often do and so before Christmas, I emailed David to ask if he would kindly resend the email, which he did. Over the last week I have been busy purchasing bearings, carbon fibre rod, beech chopping boards(!) and other odds and sods to build the clock. I also used v-carve to chop up the DFX files into pieces that my CNC machine could handle due to the limit bed size. I started cutting the plates over the last few days. Interestingly, I also laser cut a set of parts. I also wanted to compare my CNC cut wheels to accurately profiled laser cut wheels basically due to my lack of confidence in my CNCing ability! Incidentally the CNC has turned out well.



It was all looking good!!


I initially used a mix of what I considered the best parts, but it was a bad move! 
You can see there is clearly a problem with the drive through the main train:



Finally the last few weeks I got around to sorting out a new front frame. David has been a fanatic help all e way through the build. I replaced the frame and also the intermediate wheel and it seems to be running ok now:



I'm going to get it into the living room tomorrow if it passes the over night test!! Other than possibly paint the hands white, I don't think I'm going to do so much with it. I also might use a polished steel weight rather than brass - I'm not very good with aesthetics but thing it looks quite fresh and modern all light wood - or unfinished :-/

Hi Chris

Nice to see that your getting some shop time and makin bits n pieces. Give it a bit of time to run itself in and it should be a keeper.  :D :D

Cheers  :beer:

It's 8am and the clock has been running now over night! - hurray :-)

I remember countless nights of coming down to a stopped clock when I had the gearless clock build.

Happy days!

What do you guys think to a steel/ally - none brass weight and white hands?

Very nice, Chris.  :clap:

I thought you'd been quiet for a while, obviously still busy though. The hands need to be more visible but not sure what would look best. How about alloy hands and weight?

Will it survive in the house with children ;-)

I agree with Harry, you can't see the hands, they need to be in contrast with the background. I would go for something dark, dark blue or black for the hands and how about blued steel for the weight, especially if the screws are blued.

Thanks guys,
Garym, I've been pretty quiet and not up to much for about 4 months, since Christmas really. Works been hard and I fall asleep now where as I use to play for a few hours in my workshop.

A blued weight would look awesome but I doubt I could blue something that big, certainly not evenly! Yes, dark would work for the hands. Worse case I can always re-paint or cut new ones if I'm not happy.

dark hands for sure. How about a piece of copper pipe capped both ends and filled with shot or sand...easy to adjust the weight as well.
That's what I used for my wooden clock 'Genesis' by Clayton Boyer. Made out local hardwood. Now in bits as a couple teeth broke on the sprockets. Kids can be a pain at times, especially if not your own    :wack:

Thanks guys, I appreciate the replies!

I didn't get your message in time. My wife wanted white hands, so I did white front side with black edges and back...looks quite nice I think.

In the living room.

Looks great on the wall, Chris, if a little vulnerable. :bow:

How will it cope with inevitable dust?

Never mind the dust - when the weight drops to lowest point, it's only about an inch from my youngests' grasp!

Could you not use a piece of lignum vitae for the pendulum weight? It would be in keeping with the wooden clock. You could go down to your local bowling club and pinch a bowl when no one is looking!

That's what Micktoon used to make a wood carver's mallet he described in a recent post.

I don't know what they are made of, but a quick check of densities shows the heaviest woods topping out at 80 lbs per cubic foot, and brass up around 500. Sorry about the imperial units, but the ratio is the same for metric units.

Bowls? Mine are Tyrolite but others- I believe - are Hensolite.
As for Lignum Vitae, it is fairly classic stuff. My first bits were from ships' stern tubes when ships were broken up on the Tyne. I bought some to make Northumbrian small pipes and then both African Blackwood and Brazilian Rosewood. As the blackwood is in fairly short supply( and expensive) for things like clarinets, I donated my remaining stocks to a Professor of Saxophone's husband who makes and repairs wind instruments.

As far as lignum is concerned, it can be worked with ordinary hss lathe tools and polished with the turnings which contain natural oils.

Maybe old lignum bowls which have cracked and go to car boot sales can be salvaged.
Blackwood is in such short supply that the turnings are mixed with resin- and re-used.

Not cheap!

The clock is great and still ticking well but annoying me with only just over 24 hour run time. I really need to fit an additional pully and loop. Any thoughts where it could go?
