How will I test my product

So originally I wanted to survey people about my product against my design specifications. My design specification are:

• Size of a shoe box (excluding Pendulum)
• Made mainly of wood
• Looks just like the design
• Shows how the mechanics of a clock works.
• The weight has to be easy rewindable.

So I was planning on asking questions like:

1. Is the clock (excluding the Pendulum) about the size of a shoe box?
2. Is the clock mainly made out of wood?
3. Does it look just like the original design?
4. Does it show how the mechanics of a clock work?
5. Is the weight easily rewindable?

But for people to answer some of these questions they would either have to see the product or know how it works. As I cannot bring the actual product around with me, or have time to explain exsactly how it works I decided that I will not do a survey. I would also need a lot of people to survey which is very inconvenient and time-consuming.
I decided that I would just reflect myself on how well I have done in my design specifications. As most of them are either common-sense or measurable I believe I can decide myself if I have achieved the specification.

I will check myself if I have reached the specification by:

Measuring the outline of an average/random shoe box, and measuring the outline of my clock. I will allow myself a 10cm margin of error.

	Length	Width	Height
Box 1	30.5	20.5	11
Box 2	30.5	17.5	10
Box 3	31	17.5	10.5
Box 4	30.5	17.5	10
Average	30.625	18.25	10.375
Rounded average	31 cm	18 cm	10 cm

Other materials are allowed to be used in my product, but it has to be mainly wood. If I have achieved this specification mainly relies on common sense.
Looks just like the design is an easy one. I have in no aspect in any way changed my design compared to my final product. The slightest change causes this specification to fail.
It should show how the mechanics work
I designed my clock in such a way that it will show how the mechanics of a clock clearly. If I will stick to the design then this specification will automatically also be achieved.
Then again, I designed the clock in such a way that the weight will be easily rewindable. So if the design works out OK, then I automatically achieved this too. But if I don't achieve the 'just like the design' specification I will time myself rewinding the clock. If it takes takes 60 seconds or less in a normal (not rushing) speed, I have achieved this specification.


If the majority of the questions are answered with yes... then I can proudly say that I achieved my goal.

Update

So I have been gone for a few weeks, and then when I came back my internet wasn't working. Only recently my wifi has been restored and I can continue my Personal Project. Whilest I was gone I got a book called "Clock Design and Construction" by Laurie Penman. Although I know myself and know that I won't be able to read the whole book page by page, word by word. I will though take abstracts from the book and use them, maybe even quote them.

My friend also went away on holiday, and when somewhere in Spain she saw this amazing mechanical clock, and specially for me she made a video of it. I will get her to post it on youtube or something so I can put it on my blog.

Also when on holiday in Friesland I saw this amazing machanical clock, too bad I couldn't take a photo, but you were able to look inside the clock from the sides. It had a ... pendulum. Though the clock was different, the arms weren't lined up, it was made from metal and everything was a lot smaller, but the mechanics behind it were the same and I could reconize the whole process.

Whilest the internet was down I did continue a bit on my PP. I made my detailed design, but it is too big for the scanner, so I will have to find a camera and upload it, I will do that soon. But there are still some changes to be made on the design. I didn't add the arms yet, but I will ask my friends to help me design the arms because that's the only part I can get a little creative with in the whole clock, everything else is all practicle. I also saw a better design for the anchor in the book. Also I am scared that the weight will hit the pendulum, and because some wheels hit eachother and overlap, so I made three layers instead of two, I will colour code them.

How the wheels will be attached to eachother

I will start by taking a big board, 2cm thick which will go behind the clock where I will nail everything against. Then there will be some sort of rubber stopper, if I can't find a specialised one at my local do-it-yourself shop I can always use an ordinary stationary rubberband. Then my first wheel.

Whenever I want two wheels to be attached to eachother I will make the wheels seperately and then nail them together, but I will leave a small space between them, so the wheels won't touch eachother and won't cause any friction. The same thing will happen to the second/minute/hour hand if there is one.

Then another rubber band because the nails will leave some space for improvement or miscalculations.
