T-Brick Shed: Rafters and Decking

By -
This weekend we attached the rafters, fascia boards and installed the decking. It's beginning to look very roof like.
Cutting a short rafter to install on the pony wall. Sure is nice to have a shady work space.

Installing the short rafter on the pony wall.

All rafters are attached apart from ones on either outside edge (flying rafters).

I was working solo on Friday so to get the outside rafters on I made a couple of holders from some scrap wood and attached them to the outriggers. 

Attaching the flying rafter to the outriggers

Installing the flying rafter on the other side.

After attaching the flying rafters, I installed some blocking between the outriggers and put way more screws than I probably needed into the rafters to see they were securely fastened to the bond beam/top plate.

On Saturday we put fascia boards on the front and back.

Unloading plywood for the decking. It's good to keep those old people active.

Using the ladder as ramp to push to plywood up on to the roof.


Cutting a sheet of plywood in half to finish off the third row. It's useful to think about your building materials when making your design. I got lucky. The shed is 16' long by 10' wide. On the long side there's 2' of roof overhang on each side making the roof 20' long. On the short side, there's a little less than 3' feet of  roof overhang on each side making the roof 16' wide. A sheet of plywood is 8' long by 4' wide which (if you do a little math) figure out works great for covering a 20' by 16' space. I only had to halve two of the sheets and didn't have any waste. 

Finishing the third row.
Another lucky break. Earth acts like a thermal battery. A cob wall will absorb warmth or coolth and eventually radiate it inside. So, to stay cool in the summer when the sun is high in the sky you want your southern facing roof face to have a good sized eave to block the sun from the hitting the wall at all. This is late July at approximately 1 pm. I'll keep an eye out to see when the sun is low enough to start hitting the wall.

I thought the long eaves might block out light for the bottle wall but it looks good to me. We're going to screen in the back pony wall so there should be plenty of natural light inside.

Decking finished.

Black Soldier Fly Larva Harvester

Black soldier fly larva are voracious decomposers. Here's a video  of a some larva completely devouring a hamburger over the course of five hours. And here's a video of some chickens completely devouring some black soldier fly larva. Black soldier flies have some curious qualities that make them particularly well suiting for cultivating their larva as fodder for your feathered friends: As stated before black soldier fly larva are voracious. They will eat fish and meat scraps that you would not typically put in your compost pile for fear of attracting larger vermin. They break down organic material into usable compost extremely rapidly. As an added bonus black soldier fly larva eat the eggs of other fly species who foolishly lay their eggs in rotting organic material. This severely diminishes your population of house flies and fruit flies. I had a compost pile that was beset with fruit flies until the black soldier fly larva moved in. When a black soldier fly larva is re...

Roundwood Building Workshop

I went to a Roundwood Building Workshop this weekend. Roundwood is timber that is left as logs rather than being cut into planks. We constructed a shelter for a cob pizza oven (yet to be constructed). The timer is a mix of red cedar and ash juniper. Before doing anything with it we had to take the bark off it to prevent insect infestation down the road. The night before the project leaders charred the end of the posts that would be put in the ground. The charring is another insect infestation prevention measure. Getting the cut ends charred is of particular importance. The post holes were dug to a depth of 2-3'. We also half buried a couple of dozen roofing nails in the charred end of each post for additional stabilization. The cool thing about roundwood is that you can use features of the tree(like this limb) to add beauty and support. This limb will provide support for a girder. After we got the posts in position we back-filled the holes with decomposed g...

T-Brick Shed: Rubble Trench French Drain Installation

By -

The last thing Jean told me before she left for the UK was that I had better finish the shed project before she gets back or else. The trench was a little soggy still but I decided to press on with the french drain installation for fear what that else may be (Although, I'm hoping the "else" will be make me a delicious sandwich). I dug out the high section blocking  the drain outlet and and cleaned up a some edges before putting down landscape fabric and a layer of gravel. Putting down the landscape fabric in the trench. Landscape fabric is water permeable but significantly less sediment permeable. This will help prevent the gravel and french drain from becoming blocked up with silt. Here's my work crew. The tamp/rake tango Release the hose! Uncoiling the perforated tubing. First objective was to fill in the tripping hazard that is the drain outlet. Note how we form a sort of gravel/perforated hose burrito with the landscape fabric. We...
