Thoughts on Sustainability

This first week of March begins the transition to spring and the last quarter of winter heating. Now there is room for stacking new chunks of wood in our wood crib. It's time to replace the six cords of wood we'll burn for cooking and heating this season. By May we should have filled the crib for a total of 13 cords so next season we can burn wood collected during Spring 2015, letting this year's wood dry for two years.

For me, collecting wood is a welcome aerobic activity. I cut up dead trees and fallen limbs within a quarter mile using a hand saw or battery operated chain saw. They are both quiet and easy to carry. I cut trees and limbs into pieces that are readily carried over my shoulder and make 15 to 20 trips per day to our garage that houses our wood crib. That way I am able to log over 10,000 steps a day that helps get me in shape (and shed winter weight) for planting chores. This year I'll be able to collect about two cords of wood this way before carting the rest from our neighbor's woods more than a quarter mile away. 

I have more than two cords of wood waiting at our neighbor's and will use our electric tractor to pull many wagons full home. I'm still using grid electric power to charge its battery but I'm working on charging circuits that will allow solar panels and a pedal powered generator to charge them directly. Maybe next year I'll be able to power both the tractor and a chain saw with batteries charged sustainably. I do now use a gasoline powered chainsaw for large trees and logs, but prefer using muscle power for limbs and smaller trees. Arm-powered loppers quickly cut anything smaller than a wrist.

It takes time to realize how best to reduce dependence on using fossil fuel based energy. All its forms are so easy to burn and they greatly reduce human effort needed to perform most tasks. But, to me, it doesn't make sense to drive to a gym, fire up a treadmill or an elliptical in order to exercise. It's much more fun to be outdoors, listen to flocks of geese, woodpecker songs and spring peepers serenade spring, or late winter. This February, we've had brilliant sunny weather that's gone from 60F+ temperatures to near zero this past weekend with clear blue skies, visible in the photo above. And I enjoy all of this without leaving home!

Spring in the Air!

This last full week of February, winter transitioned to spring. Two day temperatures exceeded 70 degrees! That never happened in any winter. Broke all records, by many degrees! Inches of snow everywhere and thick ice on local ponds disappeared. Soil turned to mud.

But we're now in my favorite season: replacing wood we've burned for cooking and keeping warm, gathering sap from maple trees for syrup, planting seeds, losing weight and toning muscles.

Making Harvest Baskets

We gather a lot of vegetables and flowers. For major harvests we use a wheelbarrow or cart. But most summer days we pick smaller amounts, enough for a meal or two, berries for jam and baking, or flowers for tables and windowsills. Our primary basket was a wedding present we have been using for over three decades. My wife likes to use it for carrying her cut flowers and that often interfered with my collecting veggies for dinner.

It became obvious that we needed more than one harvest basket (that we call a trug). My wife presented me with one that works okay, but is too small, and, like her basket, has a handle that often deflects thrown peas and beans so that they miss the basket. Both handles also get in the way when grabbing peas or beans between hands when they are on opposite sides. My first trug raised the handle pretty high, attempting to make it easier to fill and empty. This design was heavy and the handle still got in the way. Permanently erect handles also makes baskets bulky to store. Empty, they take up a lot of space.

My First Trug: Too Heavy, But Won a Prize
An ideal baskets should have handles that swing out of the way. When you have more than one, they should also stack, one inside another. They should be light enabling heavier payloads. My next one incorporated a handle that could swing to the side for filling, emptying and storing. It also used only a frame of wood and very lightweight rawhide for lacing.

 The rawhide I used for the swing-handled trug came from a deer I harvested with a bow and arrow when I was still in high school. With only a limited supply of rawhide, I used one-inch wide webbing for the next pair of trugs that I made for four-year old twins. These work great and though they are a bit large for them now, they'll grow into them and should last their lifetime. To make them waterproof so that veggies can be washed in the trugs, both the rawhide trug and those made with webbing were given many coats of marine varnish that also melds the webbing to the wood frame.

Scroll Saw Bowls with Segmented Feature Ring

A year ago my wife gave me an interesting book on how to make bowls without a lathe. At that time I did not have a wood lathe and the prospect of making bowls without creating mounds of wood shavings intrigued me.
Carole Rothman Uses a Scroll Saw to Make Her Bowls 

Carole Rothman has developed techniques that transform flat boards as wide and long as the dimensions of the piece into incredibly beautiful bowls. One drawback: these bowls typically have sides that are around 45 degrees. 

I like to make things that are useful and have been planning to make a series of sturdy bowls for chopping vegetables and nuts so that the process doesn't send pieces all over the place. My wife's mother had a very functional wooden bowl and chopping knife that she used many decades.  The bowl was shallower than the one pictured above so, in order to use a scroll saw, I had to modify the technique. 
Mother-in-Law's 12.5 Inch Diameter Bowl and Chopping Knife
My first attempt used two boards of hard maple to make the bottom four layers of a bowl. Turning a solid piece of wood involves slicing through the grain at various angles. It is much easier to cut "with the grain" than "across the grain". The woodworking group I belong to introduced me to segmented bowl techniques and the advantages of creating layers that have no "end grain". For the fancy top layers, I added feature rings of trapezoids.
