I want to see if there were any examples of 6040 size machine using L Gantries, but none have surfaced yet.
Here's a 6040 sized machine and it easily cuts everything up to Aluminium. I've built several machines this size which cut everything from MDF to Carbon fibre parts for RC cars and Clocks which require fine tolerences so don't worry about it being upto the job.

The best profile to use is 45 x 90 because it makes things easier with mounting ball-screws. However, 40 x 80 will work on smaller machine but you'll just need to make plates to mount BK/BF bearings on for ball-screws.
