I bought a Pyramid wheel truing stand, Park tension gauge, and a Park spoke wrench. Measured the rims and the hubs. Used the DT spoke calucalator and ordered the spokes. These are for my winter bike and the parts are vintage....Suntour Road VX hubs and Weinman Concave rims. I chose 2x since I could get DT-Swiss, SS, DB spokes in sizes less than 300mm for $13/20 from Lickton's. Anything over 300mm is hard to get and costs allot more (over $1 each). I used Sheldon Brown's directions....I now have a beautiful set of wheels and I had fun building them too.
