4th axis question

Hi all,

 

I'm attempting to manufacture a small scale car body as part of a school competition.  Below is an image of my setup and the issue I'm having with a rotary toolpath.

 

Setup - The rotary axis is off-center.  This is dictated by the competition organizers, who supply the blank...

The issue - Where the model nose cone converges at the end, the tool enters and crosses over the model surfaces, creating crashes and left over material.  In an attempt to fix the issue,  I have performed several operations to remove excess material (Facing, adaptives, Leaving stock on the rotary passes and working my way down) but this happens every time...

 

I've also tried changing the tool offsets, without luck.

Thank you in advance,

Si.
