Thanks Ross, I was a decent build project, I used a hardware kit from WindRiver.
Thanks LBD, this one has about 3" travel which is good enough for my uses. A laser would be nice, but I'll stick to carving the maker's mark.
Thanks George, It is nice to raise the work from the table height, and it is clamped down to the main bench which is a 4' x 8' sheet on top of the base frame. I can use the hand planes with it stock up to about 3' so far.
