  • Bridge Stone Shaping (2 of 3) 6/17/18
    June 17, 2018
    9:00 am - 5:00 pm

Up to 12 participants with certified instructors. Open to those who have taken at least one walling workshop (or are certified Level 1 or higher)

This workshop will spend the day learning how to shape stones for use in an arched bridge.  Spcifically making the voussoirs (tapered stones forming the arch). Both hand and power tools will likely be demonstrated and used.

This stone shaping workshop will focus on making the stones needed for the bridge build in September.  However, these techniques can be applied to all kinds of stone shaping and walling. The assumption is that participants taking this workshop already know at least the basics of dry stone walling. This workshop will delve into stone shaping and to a much greater level of detail than workshops that focus on wall building.

Participants will start with raw quarry material and shape all of the components to the bridge. Attendees will get instruction and practice in breaking and splitting large stone, chisel and hammer techniques for refined shaping, and the use of power saws to accelerate difficult shaping tasks. At the end, you will have built voussoirs, builders, and copes. You will be comfortable using hammer and chisels, and you will have developed an eye for matching stone to purpose. There are three of these workshops. Attend one to achieve familiarity with the components of a bridge and the techniques used to shape them. Attend all three to more fully develop competency and be ready to take on your own project from bulk quarried stone.

  • One day walling workshop, or 2 day walling workshop, or hold DSWA-GB certification (any level).
