Ambitious!
How are you Cadding the playfield? Do you have a used one to measure off of and inputting that? Are you going to clear it yourself? I’d have to agree with other opinions, it makes so much sense to just buy a new complete playfield.SO much time to cad it, do art, pay for wood, vinyl print, clearing, and SO much opportunity to screw stuff up that it seems better to concentrate on other aspects and leave that one alone?
Are you also building a wire harness?
This sounds like ALOT, alongside another homebrew project holy crap. I’m 3 years Or so in on one and can’t imagine doing 2 at the same time. Good luck!!!
