Pocket bow-drill

I am now working on producing a mini or pocket bow-drill based on my larger version here

The design and specifications are not perfected yet, but yesterday I achieved an ember in 9 seconds.

I hope this size and design will be good for teaching fire by friction as I find they struggle to achieve sufficient pressure on a full sized set.

Hello

My name is Susan Harwood.

I'm contacting people who list ‘the environment ‘as an interest on their 'blogger's profile'.

I have a new blog called

SHOUTING AT THE RADIO

It is concerned with the environment, building, architecture, politics and education.

It can be found at

http://shoutingattheradio.blogspot.com/

It is in its very early stages just yet - so comments will be especially welcome!

Yours sincerely

Susan Harwood
