If you want to get a nicer looking primary, you might want to try 
using eight spokes of support instead of four.

BTW, I have used wood for primary support on my first coil using a 
12KV 30ma NST.  The wood was varnished before mounting the copper and 
it never failed. Of course I decommissioned it to work on my 2nd and 
larger coil.  For that, I used HDPE for the supports.  It is softer 
than acrylic and doesnt have the tendacy to crack.
