I am also a big fan of bolts, almost invariably cap heads in the M3 to M8 range.

Another favorite of mine is clamping a bar to the bed, machine the end, then clamp the free end while parting it off. (Although I do tend to leave a tab, Nearly Headless Nick style, don't want to risk it twisting and gouging).

I have heard stories of thermal release adhesives but don't see them for sale.
