Chris,
Unfortunately I did not take pictures during the build process. I kept telling myself I should, just never did, and since it was pushing the limits of my small machines, it would have been good to.
The table sits on the top of the riser.
That is how I had planned it, but in practice, it may work better, if the crank mech is mounted above or below the "nut" and clamped off, and the nut is left free to move the table.
Here is a picture of mine with the table, and a few other ideas I had collected before building mine.
