Rob:

Aluminum AN washers are available from Aircraft Spruce for about $.03 each.
Order AN960PD-"Size" where size is -4,-6, -8, -10, -416 (1/4") etc. Add "L"
to the end for the light or thin series.

The applications where I used aluminum washers, verses steel, include:
Shear (push rod ends)
Non structural (mounting strobe power supply)
Anything to composite (pressure bulkhead)

Use steel where vibration or shock loads are high (engine, prop & landing
gear).

Keeping an airplane light during construction is a battle of grams, not
kilos. Before putting any part on the airframe, ask yourself "Is there
anything I can remove from this part without compromising strength or
function?". I even took the air switch for the door seal to the belt sander
and ground off several ounces of brass that was useless load.
