Clockwork
« on: October 30, 2014, 09:38:04 AM »
As some of you know I've been looking into clockwork stuff recently and many of you will have heard of mad scientist/inventor Tim Hunkin, maybe even seeen one of his crazy clocks at Neal's yard or London zoo, or Southwold pier but his latest one is just brilliant.

Also came across this interesting 'perpetual motion' machine whilst researching too.

Fantastic!

Saw one his water based contraptions in London, sadly not working at the time.

Loved the Secret Life of Machines series :)

They are rather nice, quite ingenious!

While building the 3D printer I came across this in a similar vein which might interest you ... http://www.youtube.com/watch?v=q5zysLnMmpE

If you are playing with clockwork, once drawn in a 3D package (plug-ins are available that generate them automatically) gears are very easy to make.  I recently made a scotch yoke arrangement to adjust a little tool I've been experimenting with.

tim came to one of the cambridge teslathons i organised i few years ago with his wimshurst machine. rex garron,his assistant on the secret life of machines, used to be regular visitor. i havent been for a few years since i gave up organising it. too much paperwork. try to imagine writing a risk assessment for a BBB to get an idea of what they wanted me to do.

Are they anywhere on the internet that you know of, they sound like they are really useful.

That gear video was interesting Julian, I've seen quite a few weird shaped gears, squares, triangles, oval etc, one of the wooden clock kits I saw has them,  they make my little clockwork project look easy.

Happy to print you a couple to play with if you like.

Thank you for the offer Julian,  I may take you up on it when I have decided on what I need/am doing.

What is the maximum diameter your printer could do?

more weird shape gears

Comfortably about 150mm diameter.  It's big areas that take the time to print, so a solid 150mm dia would take many hours.  A skinny spoked wheel wouldn't be too bad.

Don't think the gear wheel plugin will do all the funny shapes though.

If you want to have a play, down load Sketchup (free from Google) and the gear wheel plugin (plugin only works on Sketchup V8 last time I checked).

Come on Chug, spill the beans, you're being very cagey about what you want to make!

Well are you sitting comfortably, as many of you know, I'm a volunteer at our the local watermill, most of our team are retired peeps, one is ex dentist, harley street don't cha know! anyway he has a cellar full of engineering gear, lathes, mechanical hacksaw etc, oh and his old dentists chair!

He said he had always been interested in clocks and had made a closing device for his chicken run door using an old alarm clock, to save him visiting twice a day to let them out and lock them in again, I was interested and went to see it, simple but clever, my interest in clockwork things started here, or should I say was rekindled from when we were kids and pulled clockwork toys apart.

Anyway I was telling the other mill lads about this device and one of the oldest chaps, said, "I got rid of all my old clocks after I got arthritis and couldn't fix em anymore, but clocks and old machines and old engines was my main interest", then one of the other old chaps who is good with wood said, "I'm fascinated by clockwork stuff like automata and have you seen these novelty clocks that run on water like at Southwold" after he  described it I remembered it and I said yes I had seen it.

And then the thought hit me, we have plenty of water, we have the skills between us to fabricate things from wood or metal, we have three peeps already with knowledge of clockworkings, maybe we could make a novelty water clock at the watermill, might even bring in a few more visitors, so I posed the idea to them and they said lets research it and think of some basic ideas and see where it goes.

But the old boys already know a bit about clocks so I'm swotting up on stuff so I can try and push the idea along a bit as they usually forget things, then if they do remember sometimes they can be a bit slow.

Sounds like a fun project to me :)  A water powered interesting contraption would certain pique the interest of kids and adults alike.

You count me well and truely in that group.

I believe the very first mechanical clock was water powered, of course invented by those Chinese chappies a loooooooooooooooooooong time ago.
