Hi,
another thing you will need, and its not something you have to buy, is some spoil boards.

I have a couple. They are just a squares of acrylic. They get pretty scarred up after a while so replacing them with something cheap like acrylic is good. What may not be apparent
is that they clamp directly into my vice and that there is a stop on it so that you can remove the spoil board, including the part or PCB which is screwed, clamped or even taped to it,
alter it, turn it over,or put a fresh piece of material then put it back in the vice and by virtue of the stop it goes back in exactly the same spot....so you don't lose your zero reference.

So simple. As you can see I make circuit boards this way and many small parts....like the little piece of white acetal I'm working on for a customer.
