How to create non-permanent join between two parts made of wood ?You can imagine your remote control battery place which is closed by a part that can be removed and put in place easily.However remote control is made by plastic.I want to create same scenario but with wood.Any idea to design the structure is really appreciated.It means two parts can be locked into place and can be removed easily whenever we like to get access to battery and switch inside.

I mean, yes, if it were a circle, all i'd have to do is find the circumfrence of the back gear, (on a bike) and divide the bigger front gear's circumfrence by that. but the thing is, the number of teeth vary from one set to another, and i want to make sure i'm putting my money in a new set of gears with a good enough difference. Also, some gear sets have slightly elliptical gears to make pedaling easier, (mine are too, but very very slightly.)

i'll need to know how to figure in the number of teeth and the tooth size if possible. thanks!

Is there a cheap and easy way to spy on somebody? Is it true that you could spy on somebody and see everything a person does from your own computer? I heard that there is very hi-tech in spying. Like they can look directly at your eye and take the IP address from your eye like the IP address on the computer. And they go home and see everything you do or say on their computer in 1 or 2 weeks. Does this technology exist? Is there any other technology close to this?
