T-Brick Shed: Second Course

By -
If you can't image molten lava cake, it looks like this
While it was overcast and kind of gloomy most of the weekend it didn't rain which awesome. I was able to work on the the shed most of Friday and Sunday afternoon. The blocks I made last week looked really good. No slumping! My parents easily removed the forms a few days after I put them and they looked like perfectly formed 12"X12"X5.5" brownies. Success! Hurrah! It's great news but leaving the forms on overnight is slightly inconvenient in that it severely limits the number of blocks I can do in a day. On the bright side, the inconvenience should be short-lived. For the first four courses (~approximately 2ft) I'm stabilizing the soil with lime. To mix the lime evenly in the soil I have to get it fairly wet. To get an idea of the consistency, close your eyes and imagine a Chili's molten lava cake. The soil is gelatinous and flows slowly out of a large brownie capped with ice cream. Rather than eating every single morsel of the the slowly moving lime infused mass you tamp it down and find it squishes out from underneath your tamper rather than packing down. That's what I'm working with. 

From the fifth course on I'll use straight soil without any amendments. I'll add 10 - 20% moisture but it will able to hold its form after some tampage (I'll demonstrate what 10-20% moisture content looks like in a future post. For now we can just let the suspense build). Eventually, the entire structure will be covered with a roof that keeps most of it dry in most situations. The idea behind stabilizing the lower courses with lime is that they're likely to to come in contact with water be it from splashing or flooding. It this were a garden wall completely exposed to the elements I would use lime in the whole thing.

Friday morning. Found the nails on some of my forms pulling out so I secured them with a few screws.

I'd completed half of the second course by mid morning. I had few more more boards so I made more forms. I'm getting really good at form making.

With the new forms I was able to make it three quarters of the way around by Friday afternoon.

Sunday afternoon. Time to finish the second course.

It's a good thing I'm building this shed. I'm going to need some place to store all these forms when I'm done. I'm up to twelve 12"X12" forms, one 12"X18" form and one 18"X18" corner form. I think I could probably do with one more 12"X18" form but apart from that I should be finished in the form building department.

Finished the second course being sure to leave a gap for the doorway. Starting in on the third course.

Installing my first dead man.

Into the wall with you dead man! I'm going to put some exterior shelves on the shed to hold lumber. I'll anchor the shelves to these dead men.

The corner piece fits. Yay!

Second course down! I won't say how many to go because that would just be depressing. Tune in next week.

Deadmen don't talk. But presumably they do show where they are, so you can secure shelving to them? I like the cake, but I think you should stick to gravel & lime for building purposes, otherwise it would be a bit like the gingerbread house and someone could eat their way in.

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

Apartment Homesteading: Growing Sprouts in a Milk/Juice Carton

Materials: Empty Carton, Funnel, Scissors, dry beans No shed updates this week. Jean's parents will be visiting us soon. They'll be here for a few weeks so I wanted to leave enough for them to do to keep them out of trouble while Jean and I are at work. Instead of a shed update, here's the first article of I what I hope will be a fairly regular series I'm calling apartment homesteading. Subjects may include horticulture, food preservation, alcohol fermentation, animal husbandry, materials re-purposing, function stacking and whatever else we can come up with. All these activities will be extremely small scale, typically low overhead and low maintenance. A sprout is a germinated seed that has grown for 3-10 days. You might also call it a seedling.  Sprouts are tasty and healthy additions to salads, sandwiches and all kinds of cooked dishes. Some common sprouts are mung bean and alfalfa. If you do a google search for " health benefits of sprouts ," there
