Changing driver on Akoray K106/TrustFire F20/UniqueFIre AA S1

My TrustFire F20 died after using a 14500

Now, waiting DX response, I am trying to know how to fit a 16-17mm driver in a place that can accept only 15mm driver.

I know that can be removed the brass ring (I have done it) and now it seems that can accept the 16-17mm one, but the negative conection will be poor...............................

As shown here... any other idea? http://sites.google.com/site/miguelmoreto/home-eng/projects

Also about the driver board http://www.dealextreme.com/details.dx/sku.15880

Can accept from 0,8 to 4,5???? Sure?????

Good brightness with AA?

Anybody knows?

Thanks!

This driver seems to have the right values: http://www.dealextreme.com/details.dx/sku.4735

It also has a broad copper negativ band, so it could certainly be sanded down to fit, without

missing connectivity.

A little expensive and some says 17mm diameter.
