I've never used it, but there is a Dremel bit called EZ thread that might be used for minor clean up.
If you must get a tap for the freewheel, get a bottom tap, it will clean up all the way to the bottom of the hole. (hence the name)
Agreed 100%, taps and dies that large are very costly, and its not a good place to try and cut costs at all. Good quality machinist grade tapes and dies are expensive for a good reason, materials and construction are beyond superior. If you need your hub or freewheel body to be cleaned up (threads chased) take them to a machine shop and let them do the threads for you, it will be worth the expense, and not real bad either.
Good luck with your wheel and the freewheel, as Pastor Bob said, its satisfying to rebuild them, and the experience the finished product.
