I've never used a fly cutter, I've always used a face mill, I have a nice Walter F4041, that Ken helped me get.

Yes, that's it. 

If you have say a 2" cube of alloy in your vice to the left of the Flycutter and you crank the handwheel clockwise the table will move the work under the cutter from left to right. The cutter, rotating clockwise will move in an arc from the front of the material to the back. If you stop moving the table once the cutter reaches the left side of the block you'll have a nice pattern of single "arced" cuts across the work. If you continue moving the table then you'll get the classic double hatching effect you get with ordinary endmills etc. Either way the job will be flat if the head is vertical but it looks nicer with a "single" cut.

If you mounted a block of alloy near the edge of a face plate on your Lathe and faced it off the work would look very similar.
