Only a couple of feet (height)of wall can be built and then it has to be left to harden/dry out for a couple of weeks. Outside walls have to be covered to aid drying and stop rain leeching the lime out.
They are repointing the medieval church tower close to me. The scaffolding has been up for months and the whole tower wrapped in woven plastic. Must be costing a fortune.

I don't think there's any magic formula. The advice is often do it by hand to minimise damage, but it's advice that doesn't make sense. Using an angle grinder very gently puts far less peak force onto the bick/stone than any manual smacking. The gentler the better.
