8 direction mill from sherline.
rotary table bloted on the left side, mounted to a 90 deg bracket.
adjustable tailstock bolted on the right side
1x4 1/2in. alluminium rod supported between tail stock and rotary table.
4 flute end mill off set from the rod 1/4 in forward, so only half the end mill will be making contact w/ the rod.
What I am trying to acheive is trimming the rod down a few mm's and adding a series of steps so that the rod tapers, in steps from a little less than one inch down to a little more than a 1/2 in, I am not exact on the amounts yet, blue prints are still IP.....
So does this sound doable/possible? I would imagine that I would have to keep my cuts light and my feeds fairly ginger, but since I cant affoard the lathe and mill, I dont mind the part taking a little longer to fabricate....
any tips suggestions?

You wouldn't have to cut light with that (assuming the machine can handle it)
You could mount the Rotary and tailstock aligned on a plate and mount the plate "crooked" on the mill. Then you can just mill the taper without messing around with "steps".
OR
Mount the rotary table with the axis pointing up, but shim the base to match the taper desired (ie as if it was on a Sine Plate). Turn the rotary table while side milling to make the taper.
OR
Mount your stock in your spindle (many ways to do this). Clamp a lathe tool (cutter) in your vise. Start turning.
The taper will be an "eyeball" job with this method.
