Free steel!

Sorry I'm not giving it away but I just landed myself a hole buch of 100 x 100 x 5 mm steel tube from a cousin who is tearing his house down. He said as long as I cut it out I can have it so I wasted no time. There is actually one more 2.5m length still there but it's incased in brickwork still. As soon as I saw it I started thinking router table for a full 8x4 sheet but then also wondering maybe something smaller to machine aluminium however I do still have my mini mill I am wondering about upgrading a little. Ether way it's a huge temptation to build another machine once my monster is all finished and earning some cash.
