I'm sure there are tons of these on the market I could buy, but making them is part of the process for me, and the process of making them will yield information and learning to benefit other similar projects where I know there aren't the specific shapes/sizes I need 'off the shelf'

Think about the back of an oven, or washing machine, where there's a dimple to provide clearance for a screw head. Nothing fancy, pretty simple.

This is for a product I hope to start producing soon, but other products in the works will need specific and custom sizes I may not be able to find, so this first round is sort of a prototype in and of itself.

Bottom die will be static, steel located on a pin, upper die locate on same pin, attached to the ram of the press. Apply pressure, release and done. Striking would be more ideal, but the press will work well enough for what I'm doing.
