So, I've ordered a Gender bender for my cable so I should be able to test all the electronics.

I've got some Micro switches from an arcade cabinet I made ages ago, so I'm going to try and make some limit switches also.

my thought are, how am I going to make everything accurate enough by hand? I have recently bought a square ( something my college amazingly lacked) and I plan to mill the ends of me metal by hand so they are perfectly square,

but are there any tips for getting everything bang on?

The tools i have to get this together are a square, small drill press, auto punch and a rule so getting this thing together will be my biggest challenge.
