I've heard (not sure where) never to use a pencil to mark aluminum parts.
I have a sweet set of steel T-Rules with holes punched every 1/64" inch. You can draw straight lines parallel to an edge by putting a mechanical pencil point in a hole and 'dragging' the ruler down the edge of the part. My super-fine sharpies are too big to fit in the holes in the ruler. They are made for 0.5mm pencils.
I'd love to be able to use this to mark holes on the parts I have to fabricate/drill, but am concerned about what I've heard re graphite and aluminum. Anyone know whether I can can use a pencil if I clean the graphite off when done?
Thanks!
