In my new build wish list thread there's a sub-discussion about the size of the 4th axis rotary table.

This topic deserves it's own thread as I've read about it in numerous other threads and we can shed light with a simple pros and cons list of the smaller vs larger rotary tables.

Please comment and add to the list and by the end we'll have a solid reference.

6" Rotary Table (30290)

Pros

• $235.18 cheaper (and cheaper to ship)
  
  • $1,287.83 for 6" 4th axis kit (30290)

  • $272.80 for 6" 3 jaw chuck (30292)

• $310.20 for 8" 3 jaw chuck (30291)
• $1,914.61 total for 8"er

• 25 lbs lighter (weights are shipping weights but since we're taking the difference the packing materials cancel out, roughly)
  
  • 70# for 6" table only (30267)

  • 98# total for 6"er

Cons

• Not as rigid as the 8"er.
