Hadn't seen this posted yet. These are places where you can find cheap parts, borrow tools and get help for cheap / sometimes free. Often times you can do worktrade for shop time or parts. Tons of these places out there. Most are staffed by volunteers; be nice to them, don't act like you're entitled to anything, and they will usually be nice/patient with you.
