I just wouldn't like someone to be put off, because all of a sudden it got too expensive !.MDF is 'almost' free LOL and a great way to learn. Major components can be re-used later if neccesary

Yep I get your point.! . . . Respectfully thou I don't agree.!!. . . And here's why.?

Steel box section is relatively cheap and 50mmx3mmx7.5mtr lengths compares roughly around the same price has 25mm 8x4 Mdf sheet, I pay £26 per length of steel.
For a small machine then it would probably take a full sheet MDF. One 7.5mtr length steel will build the same small machine.

The sundries involved IE Screws, nut's & bolts etc both need. Steel doesn't have to welded and can be bolted thou for sake of £50 a welder makes slight work of it.
Just because something looks expensive or hard to do doesn't mean it is.?
The difference in performance and longevity are night and day and it's a one time affair still with lots of learning and enjoyment.!! . . . The fun just last's longer.!

Well that's my take on it anyway.!!
