I have an early valence question. There are four little holes on the bottom edge of the valence. What're they for?
swag: drains?
screws X 4
Optional rear diffuser?
Drains or mebbe forming or aligning pins....
Sometimes when you are doing funky deep draws in metal, it pulls and slips..
Punch extra holes in the sheet, then ram in pins so the metal won't slip when you hit it with the form die...
Or, holes could be for alignment to align the partially formed part for a secondary forming operation..
