@ Jazz..(or Jonathan if you Know) Flat bar say 2" wide ontop of what and fixed how??

Jazz has said previously on this forum:

bed made from 40x16 strips spaced 10mm apart to create Tslots.

But I recall him advising that greater than 16mm thick would have been better, simply for the extra strength and I guess you can surface it more times.
