I would not recommend blueprints but have a look at TFI on YouTube This guy if you follow his tutorials you will be almost able to construct anything in Inventor. Some time a bit long winded be a massive amount of Information.

@Tony, These are excellent. Just modeling parts is only half the job. We still need detail drawings. Finished detailed views (blueprints) like you’ve provided is what he has wisely asked for.
Being able to design/model a part is worthless if you can’t convey that information complete with design intent and tolerances to the fabricator.
Both sides are important. Understanding a sketch and being able to model it is important, and understanding real life objects and finding arcs and halfcircles is also important.
