Love my washboy , use it for pretty much everything, trick is to make sure you polish before it's dry. I always have 2 polishing rags , one for the first damp polish off then a dry one to finish.
As for the rest of my kit , as pointed out above , they are merely improvements on old technology designed to help one doing the job , but not a replacement of knowledge and skill.
The only electric cutter the guy had who taught me - ( for general use , he did own a large clipper for terrazzo )- was a small portable with a carborundum wheel . We had homemade set squares made from ply , string line , chalk lines etc etc. I never used to use pegs , always worked in chalked line boxes working away from the start point and spread the tiles to meet the edge of the box , you had to do this when using quarries .
Blimey , if it wasn't my turn for the cutter and I was doing quarries , it was out with the toffee hammer to cut L's or round soil pipes in the floor lol.
Diggy :smilewinkgrin:
