Yes it is possible but it needs to be done correctly and using heavy duty profile which is very expensive when you factor in the correct fixtures etc required to make it work. Flimsy 40x40 won't cut it and You certainly won't get much machine for £1500 using profile for the frame.
Steel in comparison is very cheap and stronger but requires more effort and skill on the builders part. If your on a budget then forget profile you just won't do it and have machine that's strong enough.
