Ugears 20 minute timer

Postby Mark » Tue Aug 16, 2016 6:01 am

This is a little project that will only take a few days. The kit had been delivered to my parents and I've only just had the chance to collect it.
It's the Ugears 20 minute timer. Supposedly a fully working timer which will time from 1 to 20 minutes, made entirely from laser cut ply, cocktail sticks and a couple of rubber bands.

Image

The laser cutting is excellent and so far it fits together nicely. Anyway, this is the contents of the kit. 4 laser cut frets, a pile of cocktail sticks, and a couple of rubber bands.

Image

Image

The instructions are clear and easy to follow (so far !)

More anon.....

Yes, it's a strange choice of material. I think it's a visual alarm rather than a noisy one. Interesting engineering though. I've got all the parts in front of me, and I still can't work out how it's works !!

I'm not convinced that it will be that accurate to be honest.

Nice little project, a bit more than 20 minutes to put together though :laughing-rolling:

It's going to be a couple of weeks before I can update this thread. I've done some work on the model, but am back in China on a business trip, and Photobucket is blocked.... :angry-banghead: :angry-banghead: :angry-banghead: :angry-banghead:

OK, here goes ! The first task is to produce all the gears that make up the mechanism.

That's the first gear assembled. Then you need to add the axle. This is a cocktail stick, albeit a good quality one !! The gear is all a bit wobbly, until the axle goes in, then it is rock solid.

Image

These proved quite tight to get in and needed sanding at times. You have to be careful of the ends as they break easily and the length is critical.

There is a gauge to help get the gears on the axles in the right position.

Here is the pendulum

The winding mechanism is really well designed. It's a ratchet still all made from ply. The laser cutting is really accurate and it works amazingly well.

The tongue on this is the part that triggers the 'alarm' and stops the mechanism from unwinding too far.

Interesting "model" is any glue required?

Nope ! No glue required. It's all push fit, and mostly a very tight fit. The cocktail stick axles are particularly tight to get in.

Here is the finished collection of gears and gubbins.....
