I have a Savvyhead in my game, but she has not yet done much with her workspace, and has certainly not pushed it to its full potential (she's a new player and only just getting the hang of AW). But once she starts to get into the groove, I'll revisit this topic with some examples.
I can tell you this - the options she chose were: a truck or a van, skilled labor, and a junkyard of raw materials.
She decided that it would be interesting/useful to make her workshop mobile, so we decided that she has an ancient military surplus, Korean War era 2.5 ton truck (affectionately known hereabouts as a "deuce-and-a-half") and a large trailer, which contains most of her tools and junk. For right now it's parked in the hardhold where they're posted up, and she has unpacked/expanded into an adjacent vacant lot, strewing her junk about to make it easier to get to for various projects (last session she fixed the main pump assembly that provides the hardhold's water supply).
Her skilled labor are Trudy, Minx, and Wild Bob. Trudy is handy with a wrench but is a trouble-maker, frequently and easily getting emotionally entangled with the locals. Minx is Ghislaine's (the Savvyhead's) protege. She's very young and learns extremely quickly, and Ghislaine is torn between wanting to nurture her fire and being threatened by her potential (player's idea, and a totally awesome one!). Wild Bob is extremely creative, especially when it comes to jury-rigging things, but he is a wide-eyed conspiracy theorist. In particular, he'll go off on lengthy diatribes about how electricity is somehow "broken," and how it had to have worked differently before the Apocalypse. His eccentricities are tolerated because he's good at his job.
Her latest project is to rehabilitate an old two-way transistor radio that recently came into her possession. Her workspace doesn't include transmitters and receivers, so it's taking her either time or a fuckton of jingle because she has to purchase all the (relatively rare) spare parts she needs or cobble them together from the junk in her stash. I suspect that this bit of gear will eventually figure strongly in her Augury once she takes reality's fraying edge (a move in which the player has expressed an interest).
