Centuries-old technology may be all well and good if you can manage
it, but
for some jobs there are better alternatives.

My best attempt was when I managed to get the mortar just right. Not
just adding water but chopping and folding and so on. When it has the
right amount of air incorporated, it seems to work much more easily.

Also, frog up or frog down? I believe they should usually be frog
down with the frog fully filled.

Brick manufacturers tell you frog up. (Stronger job)
Brickies lay them frog down to make them easier to lay.

You hardly ever see frogs these days anyway, they come on pressed bricks.
Most bricks are extruded and wire cut nowadays.

and some have to be laid cut direction down so the face doesn't hold
water...Â* ....

Cheapskate brickies lay them frog down because it saves a lot on
mortar. They frog stays more or less empty.

causes all manner of swearing if you try and attach something like
a new door frame with frame anchors and you drill into a stonking
great void.
