Adding a Roof to a Shipping Container

We have been storing supplies from our solar manufacturing operation in shipping containers left over from a cancelled contract. Over thirty years one of their flat tops deteriorated and leaked badly and needed a properly pitched roof.

The upper 20 foot long corner members were no longer strong enough to support a roof with snow loads so two aluminum 3x4 inch "I" beams were fastened above them to the substantial cast steel corners that were used to pick up the container.
The two longitudinal members that support the roof trusses: Each has 11 pairs of 2x2x1/8 inch aluminum angles to sandwich each truss
Four 1/2 inch thick plates each tapped for four 3/8 x 2.5 inch bolts that together capture the corners of the shipping container
Eleven simple trusses were fabricated using 2x4's for rafters and a 2x6 by 8 feet for the horizontal member. The pitch is 45 degrees so that the metal roofing readily sheds snow and the south facing side can one day support photovoltaic panels.
Eleven trusses each with three pairs of 1/2 inch plywood gussets, glued and screwed to the members
On each side, five 2x4 horizontal purlins were screwed to the trusses to support the seven sheets of corrugated steel 38x80 inch 29 gauge roofing.

The triangular open ends were then protected with corrugated clear polycarbonate roofing to keep out the weather but let in light.

 Waiting for delivery of supplies took longer than the six days it took to put it all together. Maybe next summer we'll paint the container barn red like of other outbuildings.

Expanding Mushroom Production

It's been awhile since I've made a blog entry: nothing much new to write about - I've harvested the same crops, split and put away the same size wood for burning in our stove and cared for critters through the long winter, bubbling the pond to keep fish alive. Maple sugaring went the same as other years.

Gathering wood, though, this year was different: a pinched nerve in my leg prevents me from carrying logs out of the woods so we got a delivery of logs, eight cords worth. It's been more than a decade since I've had to order logs so I wasn't prepared for the volume of chainsaw shavings in one place!
Log delivery
The largest logs are four feet in diameter!

Working through the pile reduced about 3% to chainsaw chips.

What to do with up to 4 inches of chips? Mulch? Or Something else?

To fit 8 cords into the space reserved for it, firewood had to be stacked higher than ever: to 16 feet and touching the roof!
I started using the chainsaw chips to mulch garlic but received an ad from our mushroom spawn supplier that Wine Cap mushrooms grow well in wood chips. I ordered two 5.5 pound packages of 
spawn in sawdust that would populate a cubic yard of wood chips. During a rare rain I spread the chainsaw shavings under an apple tree in a ten by ten foot square area, five inches deep. After sprinkling 11 pounds of Wine Cap mushroom spawn over this, I raked it deep into the chip bed and added another few inches of fresh chips. This bed I covered with a few inches of fresh hay to keep it moist. Luckily we received another quarter inch of rain that night to keep the bed watered. I'll have to water it whenever we don't get an inch of rain per week. This has been the driest spring in memory and the water table is quite low compared to other years.

I also ordered 11 pounds of Almond Agaricus mushroom spawn that grows in compost. Over a few decades we've been piling many, many wheelie bins of weeds and discarded flower trimmings in a pile that has grown four feet high and a few hundred square feet in area. Though the top is covered in vines, the rest has been reduced to fine compost that only has to be sifted through a quarter inch mesh to eliminate stones and sticks. Last fall we also collected a few cubic yards of composted horse manure form our neighbor that we also sifted and added to the "weed" compost in case it wasn't rich enough for mushrooms, since it has had Virginia creeper continuously growing on it for years. Because this mushroom variety is cold sensitive, in the greenhouse I built a 52 by 36 inch stainless steel tray (13 square feet), six inches deep, to keep it intact and free from varmints. The materials came from very old solar collector prototypes that I reworked into a rodent-proof tray.

The compost had to be made very moist (so drops of water came out when squeezed in a fist). After covering the spawn with compost, I covered it with a few inches of grass mulch and sprayed water to keep it moist. I'll have to do this every day or two to help the spawn thrive. It's possible to grow a crop in this tray while the mushrooms develop and I'll probably add an array of fancy lettuce that also requires lots of water and will shade the bed.

If all goes well, in September we'll have two new kinds of mushrooms to harvest!

Processing Tomatoes

Summer has been cool so tomatoes are ripening later than usual. We plant about 100 tomato plants so that we can process what we need in large batches. We share early and later harvests when there are fewer. This year we were running low on soup stock, tomato sauce and ketchup so tackled replenishing these.

Sauce Tomatoes: 2017
We use a Squeezo food processor to separate tomato pulp from seeds and skin. It takes a whole day each to pick a few bushels of tomatoes, manually grind them through the Squeezo, decant and preserve the "tomato plasma", add spices to the sauce and ketchup and can them, clean the equipment and feed what we don't use to the Guinea fowl. This year's totals: 22 quarts of tomato sauce, 31 pints of ketchup and 65 quarts of soup stock.

It takes only half an hour to cook these because we separate the plasma from the pulp using a colander which we try to float in the sauce. To keep it from sinking, we bail out the clear liquid that leaks through the holes in the colander. This process does steal some of the garlic, onion and basil flavors from the sauce  but delivers them in the soup stock. We make the ketchup after separating the plasma so that soup stock is pure tomato juice.
The Colander We Found That Works Best for Bailing Soup Stock from Sauce
We use a canning technique that uses a small amount of water in a pan covered by a jar support plate with holes. When the water boils, steam envelopes the jars and exits through two small holes in the lid. We steam these acidic products for 15 minutes once steam exits the lid.

Mid Summer Harvest

We spent almost two weeks in California visiting our two week old grandson and his family. Although a few folk looked after our animals and were encouraged to pick veggies from our gardens, we were overwhelmed by what we still had to pick. Summer squash outdid themselves this cool, moist summer and there were over 100 pounds waiting. Four of the Italian zucchini were hiding and grew so large that we're letting them fully ripen so we can harvest their seeds.

Italian Zucchini Growing Through the Fence
Early Tomatoes 
Greenhouse Harvest Included Guinea Fowl and Hen Eggs
Purple Pole Beans and Sweet Hungarian Peppers with Cupcake
Of course we can't eat or preserve all this food so we donate most of it to a homeless shelter, 127 pounds this week. When tomato production peaks in a week or two we'll process them into sauce, ketchup, soup stock and bags of sun dried slices. 
Pears Showing Surface Cracking

 Pears and early apples are disappointing. We missed peak ripeness period of our early apple tree and most of the fruit had fallen and was not suitable for cider. We will make a few pies with these but we have applesauce left over from earlier years so we don't need to make more. We will make pear cider in a few weeks when they mature and hope cracking doesn't hurt the taste.

Ocean & Beach Mobile

This spring our pregnant daughter asked me to carve a wood mobile for her new little one because commercial ones were primarily made of plastic and fabric. At the time I was learning how to carve birds out of wood and welcomed the challenge. My target for completing the figures was our older daughter's May birthday because she is a wonderful realistic life painter and I'm not. So we shipped 15 figures in early May to give her a few months to paint and ship them to California when the baby arrives.

My first choice was to dangle the figures under a large octopus but both my wife and our new grandson's mom thought this too scary. So we settled on using a tree branch that worked out quite well.

 The above photos show straightened fishhooks used to hold the figures while painting. A few of the birds kept these so they maintained their orientation. The rest of the fishhooks were removed and replaced with swivels that are easy to attach to fishing tackle snaps with an additional swivel so the figures can be oriented in specific directions. The figures are robust and can be readily handled and their positions switched, then pointed in an appropriate direction.
