Edit Reason: Clarify that I tried installing in an actual card
)
Small update after drilling a bunch of holes in a FR4 sheet and attempting to install eyelets in it with the cambion press while paying close attention to how aligned it feels under the punch and using the cone to help guide my hand:
I got a couple almost-perfect eyelets in a row, then a bunch of messy ones, a split one, and then a few pretty good ones and one nearly-perfect, possibly perfect one.
Some more observations:
The cambion press expects you to mount an anvil or something to the base so there is extra space besides just the punch travel distance, and I've been using a small aluminum block in that space as support for the eyelets and board. Not the most secure, and I think that might be a source of error. It's also not optimally sized for the board thickness (it's a little too tall), and the punch is most secure in the cambion near the end of it's travel (no radial movement whatsoever), so maybe that's an issue as well.
Going forward I'm looking at either getting the keystone tool holder and anvil stuff to mount in the Cambion press base with a spacer (after double-checking measurements), which should provide a secure base with adjustable height or alignment. Maybe finding something else with appropriate height and a wide enough base to provide a secure backstop for the eyelets in the cambion press. Or, getting the magnet chuck for the Dake arbor press. Hmm...
In the meantime, at least I know I can get good swages by hand.
