Great!

As to your comment about the sander, you can easily get your indexer to spin by just doing a MB 36000 to get it to spin 100 times, then MB 0 to spin it backwards to zero.

Flutes are ridiculously easy if you use the fluting gadget with Aspire. You'll need the right round bit to do that though. Takes almost no time to cut beautiful flutes, perfectly situated. No math required.
