Xmas came at last,I bought a few bits from Axmister,the 2 I have used so far are the Proxon mill/drill bit(2mm) and the Aminster set of 4 sanding pens in various grits.The pen sanders are really good for detail sanding,they are aprox 6m bands on a spring loaded piece of plastic,and keep tortion very well,you can use the fine point or the rounded end to sand.The mill/drill bit(2mm) I have used in the high speed motor as a router for thinning down areas to be pierced,I had to make a plate with a 6mm hole as the base hole was to large to control the 2mm depth of cut I wanted,then in the flexi drive for the piercing,I tried using it for piercing just in the motor,but had a distict lack of control that way,heres some pics so you can see what I mean,regards,
Eric.
