Is there any way you could fit a wall bolted, 'triangular' shaped,
steel brace in the middle or do you need an uncluttered space?

I'd need to drill a very big hole through the washing machine to accommodate
the brace. It might prevent the drum rotating, too.


Hmmm, I take it we are talking about this layout, from your thread
"Granite worktop span"?

++----+----++----+---+----+---+---+
|| WM | TD || DW | +----+ | |
|| | || | 1 |SINK| 2 | 3 |
++----+----++----+---+ +---+---+

Support profile:
^^ 1.2m ^^ ^ ^ ^ ^ ^

You need a support 'twixt the WM and TD, yes? How about this (which is
what I thought Tim meant but, judging by his reaction to your reply, it
wasn't) fabricate a "shelf bracket" from angle iron and flat strip, it
only needs to be 3mm thick steel, screw it _solidly_ to the wall at the
back of the worktop. It will be more than strong enough. All you need is
3mm of space between the WM and TD, surely you must have that?

I couldn't draw it in ASCII art, so here's a quick CAD drawing of what I
mean. http://users.uk.freebsd.org/~mark/support.png

Seriously, though. I've been told that a 40mm wooden beam across the front
is sufficient. I just want to know if I can reduce this using a metal beam
(or several) as I don't have 40mm to play with. There is absolutely no way
that any part of the structure can extend more than 25mm below the bottom of
the worktop over the 121cm span.
