To polish off this post-like puzzle, cycle vertically, then horizontally.
You want to understand the arrows before you've filled all the column cycles? You tungsten-like wish!
If you've chained enough -ish words and still can't fill out all the columns, you might need to call a child-ish Dr.
This message will tell you how far to turn each grinder, whose arrows will now point to a new message - this time read horizontally. Again, consult your Dr. if stuck.
