The last two instalments of “Masterclass” have examined the theory of corbelling and its effect on a couple of practical considerations. Hopefully I have established the following, in no particular order: tilting stones can be swings and roundabouts with regard to what can be gained by being able to extend a stone out further over…
In the Autumn 2010 issue of Masterclass by Sean Adcock, he continues the topic of Corbelling starting with “Last time we saw how with given uniform stone (or playing cards/dvd boxes!) a dome can be formed according to a neat formula, the main point of which is that initially you can only extend the stone…

Mind you I don’t suppose it’s ever stopped me spouting on authoritatively before, so why stop now? I have of course used the principle of cantilevering, have some experience of in effect corbelling the bottom and…

This was developed in part 2 when we looked at the tendency to place large stones alongside and on top of each other leading to grouping. This however does not just apply to…

Last time I stated that “Inevitably a wall has faults, being a better waller involves reducing these faults, and not compounding those that are made…” a philosophy I shall now add to… When building a wall you are presented with a series of problems to solve. The nature and severity of these will vary depending…
