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.

Experimenting with your hands.
People shouldn't be afraid of stones. They shouldn't be intimidated either by people who call themselves masons or experts. They shouldn't stop from experimenting and practicing and working with stones every chance they get to build and shape and organize and arrange stones in pleasing arrangements. Discover how structural they are. Take a course if you need to. If you get a chance to actually learn and get some hands-on practice with someone who is experienced in creating landscape features, such as walls of benches or stiles and arches, you may really benefit and actually be surprised what you can learn, and how satisfying it is.

Learning From Old Hands.

Hand Picked
It was as though all the participants for this weekend dry stone wall workshop were all 'hand picked'. Aaron a landscaper from Quebec and Simon one of his employees were quite a team who worked really well together building up one side of the arch and needed very little supervision. Mike and Ewen, two brothers from Ottawa and their friend Doug caught on to the concepts very quickly and covered a lot of the building of the other shoulder. Jake form Lindsay and Dan from Rochester carefully applied all they had learned in previous workshops and worked on the arch voussoirs and made sure the quality of the hearting was up to standard. Everyone had a chance to try their hand at shaping the rugged chunky sandstone material as well and very few stones broke the wrong way. I could not have asked for a better bunch of guys to get this unique Frontenac arch structure completed in the two days alloted for this workshop considering the scope of the project and the cold and windy weather. It seems amazing that 16 tons of random stone could be transformed to one beautiful looking arch and about 3 tons of very useless looking left over material at the end of Sunday.

How Handy Is Sandstone?
Progress went well on the Saturday of the Frontenac Arch workshop. The sandstone turned out to be fairly easy to shape. The guys working on the project picked up the principles fairly quickly and were making some good structural decisions. The hearting is a bit of a problem. The sandstone we are using doesn't seem to be nestling or fitting into the spaces as nicely as we would like. It is abrasive and a bit brittle. It's turning out to be not that handy as for wedging either. The smaller pieces have much less of an ability to shim the bigger building stones, the way limestone or granite chips would do, and so to avoid the wedges getting crushed with the weight and pressure of the bigger stones we think that we should to introduce granite instead for the important pressure points. Apparently limestone pieces would not work in combination with the sandstone, as acid solutions that wash carbonates from the limestone can chemically affect the durability of sandstone.

More than a Hand Span
Sometimes I have to remind myself why I do this sort of stuff. Today Saturday it is rainy and cold and a good day to stay in doors. It is not the sort of day to be getting excited about building a wall out of stone. In fact I have to teach a course on how to build an dry stone arch. There are people coming from far away and this has been planned for many months and smugly labelled a 'rain or shine' event. There is no escape.

Do the 'hands of time' turn as slowly for a rock?
Never mind how long it takes before moss starts to grow on a tree or a rock, think about how long it takes for lichen to grow on a stone! Ages. My hands have got me thinking about this a lot recently. I have a little video for people today. Double Click the link below to see it .

Hand Ball
People often assume they can't build dry stone walls with 'round stones'. But that is not true. When I have to use smaller, chunky, somewhat rounded fieldstones, I definitely have to think more with my hands than my head. Amazingly these stones are not as difficult to fit as they first seem, once I get into the groove. The fact is, in any given pile of stones, there are very few completely round 'ball shaped' ones. Most of them are more like eggs or odd shaped potatoes and will have some length to them, and I have to use this 'elongation' to my advantage. The rule is simple, every stone needs to be laid lengthwise into the wall.

Putting our hands on the heart of the matter.
If a person puts his or her hand on their heart and begins to say something you can be pretty sure that what they are about to say is the absolute truth. There are many truths referring to dry stone walls. Wallers may disagree about some of these truths or 'rules of walling' but there is one rule that is pretty much an absolute must – 'A dry stone wall needs to be properly hearted, which requires that there be enough small sharp shaped small pieces so as not to skimp on the filling and pinning of the stones throughout the inside of the wall'.
