I saw a product called the "eliminator chuck" on youtube ([nomedia="http://www.youtube.com/watch?v=HDy0xeiq08g"]YouTube- Eliminator RC Quick Change Chuck Review[/nomedia])
I haven't managed to find a UK supplier of even if they make a version for a 1/4 inch router.
If anyone knows of a similar product that is cheap please make me aware of it.
I have a Trend T4 router and the spindle thread is about 15mm diameter.
Thanks
