Way to mount a fly cutter for a longitudinal feed?

A few possible kludges: 1) On a small horizontal mill, make up a fly cutter to fit the arbor. If the arbor is over, say, 1 3/4" diameter, make up a smaller arbor. This assumes the cross travel is enough to cut the cove in your part. 2) On a regular vertical mill with a tilting head, turn the head 90 degrees and insert an arbor with a fly cutter.
