I have a rough idea of how to install a lintel on an existing wall (to
make a new opening) using strong boys and needles. I don't have such
tools and thinking of adopting another method:
1) use a angle grinder to cut out some mortar (about 60%) where the
lintel is going to be installed
2 install one of those Catnic steel lintel "L" shaped or
similar....the lintel won't seats completely as the old mortar is
still on place but it should work fine.
3) take out the bricks to create new opening
4) finish job by installing a proper lintel just under the L shaped
one (making sure the top row of bricks is wider than the opening in
order to accomodate the new lintel). The L shaped one can then be
removed (useful for the next installation).

For most jobs point 4 would not be necessary. Furthermore, if access
to the other side of the opening is not an issue it would be possible
to install another L shaped lintel on the other side for extra
security.

How does it sound? Isn't that neater than using Strong Boys and
Needles?
Constructive criticism welcomed.


May be quicker to just use some timber a row of bricks up. Put a
horizontail rail on, suported at the ends either on its own uprights
or by attaching to supported brickwork. Nail into mortar joints to
provide brick support, bearing in mind brickwork is to a fair degree
self supporting if the bottom row is kept in place. As long as its
just the usual domestic small triangle of brickwork to support. If its
something grander & larger I'd be a lot more thorough. A lot of
builders out there just do it with no support - not recommended
really.
