This is a small quick project I use in my after school Engineering club for Yr9 students (13year olds). As with all my instructables its achievable by all and results in a quality product that works well. It only takes 1-2 hours to make depending on ability of student, this makes it a real confidence builder.

This project was used as part of a enterprise activity where students made various products to sell on a market stall, this was to raise funds to finance an electric car they wanted to build.

Learning Objective
By making an aluminium keyring KS4 GCSE students will learn and apply knowledge in a practical situation. This knowledge covers accurate use of the measurement dials on the X axis of a metal lathe, how to accurately drill to a given depth, chamfer and face off a component. This project was used as part of a enterprise activity where students made various products. By using this project in their enterprise activity students gain entrepreneurial skills and begin to see the link between time to make / materials cost Vs sale price.

Step 1: Working Drawing

A working drawing is a 2D drawing that shows you the dimensions needed to make a product or component. 
Nice project and well presented instructable.
Where was this after school Engineering program when I was 13 yrs old? This Stuff is awesome!
Looks good! I like it!<br>You might try a Design Brief with your students...<br>Objective : design/modify this keyring so that the cable can be removed and reseated so the keys can go right on the cable. (I know that changes the quick build for fundraising... just an exciting thought, to see hat they might come up with!)
Hay thats a cool idea.....thanks....i will defo use that suggestion in the future.... Jonny :)
What a great project for students! I can see how they're confidence level would improve after making something like this. You got my vote! ;)
Hi, thanks :) ...... Oh and thanks for not mentioning the unmentionable! That debate is still going!
lol.. I noticed (I get the emails, because I started the thread...) I won't make that mistake twice. ;) lol
