Take the 2-minute tour ×  I'm planning on building a home
climbing wall, made from a mild steel subframe. It will probably
be around 10 feet tall approx.  I was thinking along the lines
of using mild steel angle, cutting to size, drilling bolt holes
then joining the peices together.  Like this:  enter image

of such joints compared to welding?  Also, the wall will be
freestanding, not attached to an existing wall so I'll need to
lay some foundations, for this I was hoping to get away with a
concrete base with bolt holes alligned to accept the sub frame
being bolted straight to it. This would allow me to remove the
wall and not leave a big RSJ poking out of my garden or some
other such thing.  So my other question is, would such a
foundation be acceptable? Is their other longer fixings
availiable that could take the place of using bolts?

to be able to disassemble it, and I would go with
