    I'm building a machine at the moment. I've gone for a mixture.

    Where alu profile is handy I think, is being able to thread directly into the end of the profile (steel box section is hollow down the middle of course). So for example if you want to make an 'L' shape, you can bolt through the side of the steel section into the threaded end of the profile. Does that makes sense? That's my plan anyway.

    makes sence to me, and I can see a pattern emerging here, lets run with it in the hope that other people chip in.

    Draw here maybe

    I know it's a little late to weigh in but anyway...

    If I tried to use a welder in my current workspace my wife would beat me to a bloody pulp. Whatever I use there has to be built in situ so I can't weld it up outside and bring it in. Oh and I don't have a welder and I have no idea how to use one if I did! Using profile I can easily get it up into the workshop and work on it.

    While steel may be a better material for the mill itself, alu can be a better material for the shedless city dweller with a converted attic for a workshop

    Flaming hell... Just as I'm approaching the end of version-6 of my design, ensuring everything in the frame is made from alu extrusion and plate, this pops into my field of view for the first time suggesting that steel is THE material of choice!

    Anyway, welding in the caravan would probably be a no-no... And alu should look prity....
