Putting a handy 'spin' on it.

Hand doubts.

Apparently watching a dry stone wall being built by hand is a lot less exciting than I had imagined. Case in point was the demonstration project we took on at Kingsmere Estate in Ottawa last weekend. On the first day of this special Labour Day event many of the visitors just walked by us without so much as a glance our way. The guys working with me were all as baffled as I was about this phenomena of people not finding what we do very interesting. I would have thought seeing masons chiselling and shaping big stones and skillfully fitting them into a stone wall would attract more attention than it does. However the opposite often happens. People who come by will usually glance once and then must decide that what we are doing is less interesting than watching someone cut their lawn. At Kingsmere that Saturday people must have thought we were just poor labourers who couldnt even afford to take time off for a holiday weekend. They looked like they felt sorry for us too because they would often look the other way as the walked by.

Fixed By Hand with the Materials At Hand.

For sure, this was not a slogan that you would want to have printed on your business cards or your truck. And I don't think we need to confuse people by telling those who ask us, that we never advertise for work, because most of it is 'repeat business' (even though apart from referrals, it's absolutely true). Our 'repeat work' of course is for clients who want us to do more nice work, not keep fixing things we've built badly, but in this case it was a good honest repair needing to be done on a vandalized section of well built wall, and it was done at no cost to the town. I wonder how many other things in the park get fixed at no cost to the town?
But I digress. The fact that a construction company comes back to fix what they do, seems like the kind of thing they wouldn't necessarily want to advertise. Most people dont want to think about, or have anything to do with the idea of something needing any maintenance. That's why municipalities love concrete.
But concrete fails too. And often it has to be redone or sawn out at great cost when there has been damage or changes needed to be made, or more often than you would think, when it has been poured in the wrong place. We built a dry stone wall next to a parking lot being built where we saw a municipal construction crew working for weeks surveying and forming and pouring concrete curbs that all had to all be painstakingly jack-hammered out afterwards and redone, because it was all built to the wrong grade specifications. When concrete has to be torn out or fixed it usually isn't what you would call redoing 'nice' work.
As we unceremoniously rebuilt the section of dry stonewall at the Scriven monument, the mayor and a council member came over and watched us. They just happened to be there to be filmed by a TV crew doing a news segment about the new playground that had been recently installed in the park. I sensed they only saw that our 'wall' needed fixing, not that it was getting repaired without delay, without any fuss or bother, without ordering in expensive replacement parts or materials, and all of this done without having to take a lot of damaged material away to the dump; which is where the old busted steel, wood and concrete from the previous playground had probably been trucked off to.

Hands On Inspection of an Arch and Walls Without Mortarboard or Scaffolding
Akira Inman is a stone mason in Toronto who came to our Rocktober Festival in Grand Valley in 2009 , and then through having met with Thomas Lipps (who we sponsored to be there) was invited to be a translator in Ventura last January, for the Japanese stone masons who came over for the Stone Symposium in California, and were demonstrating the ancient Anoh tradition of dry stone construction.
The Former
Prior to the 20th Century, the support for a new arch was called centering. The arrangement was similar to the technology involved in the construction of a wheel. Another method used for smaller arches was to pile sand on a wooden platform to create the desired shape for the stonework above. It was quite simple then to remove the loose sand when building was complete.
Nowadays it is much more common to cut the required shape on at least two boards then to cover these with strong cross pieces or with bendable strong materials such as marine ply. It is essential that the former of whatever type is strong enough to bear the weight of not just the arch rocks but also any material which will be built on top before the former is removed. Any area of weakness can result in failure.
The support for the former should be resting on a solid base. Bricks or blocks are ideal for the support as they can be easily knocked away when required.
Care is necessary when arranging these support so that the former can safely be dropped down to allow its removal, without interfering with the stone work. I have heard of people being required to set fire to the former to remove it as it was not possible to get it out any other way!
With a half moon former it is possible and useful when placing the arch stones to mark lines on the outside to indicate the required slope of the builders and especially the risers.
When the desired arch is not a half circle, the lines should be drawn from the theoretical centre.

Caught on the way down.

Wouldnt it be nice if you could just levitate the stones up to where you need them. This one looks like it is on its way up to Joe, but it's caught in time on its way down. Most stones are on their way down. They are normally moving very slow in that direction, unless of course if you push them or throw them.
