Hi Guys

You cannot test your setup without using real cards.

Got it, so that confirms my suspicion.

The Cambion and any setup that requires a bottom holder is not the right approach for eyeleting a card - it may be okay when setting eyelets into floppy material, but not for a card.

Most arbor presses come with a flat thick steel bed which is preferably polished so the eyelet card can slide freely on it.

I see. I had thought it might be preferable for alignment to have the single point for the eyelet to rest against with the center guide pin. However it does get fairly inconvenient trying to keep the card balanced and level on the small support block I've been using while also operating the cambion press, and I assume that is why you don't recommended it. Using the Dake press which has a table like you mention, though not polished, is much nicer.

The arbor press will definitely work better bolted to a sturdy table even though you do not have to apply high force to install eyelets.

Yeah, keeping the cambion from tipping has been getting annoying and cumbersome.

Regarding the card layout: have you seen the inside of an old Fender? The layout is designed for the parts to be used, arranged in now classic shapes that make recognising the circuitry very easy. The point is really to use the space wisely with a minimum of jumpers on the card. Generic cards with two or three rows of eyelets or turrets makes tracing and repairs much more difficult later even though it looks neat.

Noted. I suppose that means the swiss-cheese practice card will only be suitable for breadboarding throw-away stuff.

Based on your above input, it sounds like the cambion isn't going to offer much advantage over just the Dake press, despite being made for terminal swaging, and it'd be a better idea to focus on getting things working with the Dake, which does have the nice big table and doesn't require precise vertical positioning of the work to perform at it's best. Magnet chuck here we come.

Thanks for the feedback! Also for you patience, I imagine it's probably a headache on your end watching this unfold.
