I have not tried this, but thinking that a couple of rods with a coupling of some kind (nut, sleeve, hole drilled in stock etc. etc. that would allow the existing universal support to easily slip into) just add them to the existing universal rods as a slip in fit and should give you a bit of hight addition. This would also allow a perfect fit for each rod in the hold downs and screw clamp systems. I am new to the tormek so not sure if this will cause additional problems with stability etc. (Jeff would certainly know of any drawbacks to this plan...)
Just a thought.....
