About 160mm if you're happy being limited to only using 1:1 or 1:2 ratio without changing the belt. Don't quote me on that though as I need to draw it first!

It would be fine with 1/2" thick plate, but that doesn't really change the conclusion as it's still expensive.
To be honest I'm seriously thinking about going back to the shorter gantry as in my orginal designs. I'll need to weigh up the pros and cons.....
