New Machine Build Rotating ball nut

Hi everyone,

I'm building an 8' x 4' router table, here is what I have so far:

I'm using 2 x 2510 ballscrews under the cutting table for the x axis and have hit a problem. I've realised that I won't be able to hit any speeds higher than around 150 IPM with my current setup, so am looking at a rotating ballnut idea. It seems that I can keep all of my existing hardware and just find a way of revolving the ballnuts I have.

I was wondering if anyone has seen anything like these:

The first part I believe is from a chinese machine, so I'm rather hoping I'll be lucky and get a response from the manufacturer saying they can supply me with some. If not, have any of you guys any ideas on where I might get something like this, have 1 made or have any ideas of existing products that I could salvage to make something myself without too much work???...?

Thanks in advance.
