Not sure if you saw the post on VN or not, but the woodworking bench in woodworking shops is not giving a bonus to carpentry. I have tested it in a beginner and an expert shop, I assume journeyman is the same.
A couple of other issues. Apparently from what one person was saying in chat, although I haven't checked it myself, the anvil in tinkerer shops is giving a bonus to armorcraft. Sounds like the anvil for tinkerer shops and blacksmith shops is the same object.
By standing outside an expert shop and opening an appropriate form, I can get the +75 to a skill and then open a structure construction window and use that +75 bonus while applying resources (as opposed to just getting the bonus while making the objects inside the structure as intended.) This isn't a real big deal as you'd have to have a completed structure almost right on top of the structure you're working on, but it's still a bit of an exploit (although of very limited use due to the close proximity that's required)
