Hi everyone
Ground 3 of the current wedges so looks like wedge-and-feathers will fit
into 12mm drilled socket.
See where that gets me for now.
Appreciating all the inputs.
I will want to forge something which has to cut.
Thanks everyone.

Did you look at capping? Seems simple enough, and couldn't be cheaper (if you already have a drill) - some old carpet, a hammer, a steel rod with a machined end, and a £10 box of caps.
You only need to drill 8mm holes, and though you might want to drill them a little deeper than for wedge and feathers, you need less of them. Wedge and feathers is about cutting straight surfaces, capping is more about smashing big rocks into smaller ones.
While it's good for breaking boulders, I don't know if the technique could be used on a face; but cavers use it a lot to open up leads, so maybe. Probably work, but it might be a bit slow on a face though.
