Fence is all metal.

I clamped a piece of wood to it for the rabbet.

Any recommendations as to what wood to use? Hardwood or maybe MDF (supposed to be very stable) or even plastic? Do I laminate the fence for less friction?

The fence is a rectangular aluminum extrusion. I don't want to bolt all the way thru it as this will compress the center of the tube & distort it. Should I tap the aluminum & use a counter bored or counter sunk screw thru the wood into the aluminum? Or make a relief hole on the other side of the fence and screw thru the fence into the wood?

Wish I had a drill press to make a nice perpendicular hole.

Now I'll have to figure out how to adjust the fence indicator so that it reads the right measurement when the fence gets wider. [img]/forums/images/icons/confused.gif[/img]
