One rule that I learn painfully every time I build anything off late is that one has to take some time at the beginning of the project and gather all the parts all at once before beginning to build the project.

Right now, I am waiting for a measly 50pf trimmer capacitor to build and test the next stage of the Norcal 40a. And I end up paying for postage twice, just because I missed ordering the part when I ordered for parts from a source the first time. This is a reminder to myself that I shouldn't do this mistake again.
