Monday - Radiant floor tubing

Ma'ikwe's radiant floor heating will be heated by a boiler system in an adjacent building on her site. She plans to share the "power house" with another family living in the house next door. This structure will provide electricity from photovoltaic panels, house the wood fired boiler, and serve as a rental unit. In preparation for the boiler setup, a conduit was run under Ma'ikwe's foundation for electric and water tubes. Before the radiant floor tubing was installed, we needed to insulate the inside of the foundation with rigid foam insulation. After cutting the insulation to size to fit around posts, plumbing, etc. a layer of remash was placed on top. Remash is a metal grid of heavy guage wire that is used for concrete reinforcement. Parts of the remash were cut to fit around the posts, conduit tubing, etc. The radiant tubing is spread out and tied down to the remash to hold it in place. Our tubing has a 2 foot bend radius, meaning that we need to be careful not to bend the tubing too much to avoid breakage. After the tubing is in place it is necessary to connect both ends to the tubing that runs to the boiler for water circulation. Four inches of concrete will be poured over the radiant floor tubing later this week. In preparation for the concrete pour we are making concrete forms for the wheelchair ramp on the southside of the building, the doorsetp in the southwest, and a barrier around the water/electric conduit to make it accessible later on. (After pouring concrete there is excess that needs to be used up. Setting up forms for ramps, steps, etc. is a way to use up excess concrete instead of dumping it somewhere on the property.)

Tuesday - Scything and Chickens

Today was mostly a rain day. In the morning I took care of feeding the chickens while Dan was out of town. I did some more scything in the orchard and will be using the grasses for mulching in the garden. The chickens are now fully grown and are being fed ground corn for their diet. Dan plans to keep the hens through the winter for laying eggs and slaughter the roosters for meat.

Wednesday - Floor Pour!

This was the day that our concrete crew came to the site to pour the floor for the house. The radiant floor tubing was placed on top of blocks so that it would be closer to the surface of the concrete floor. The concrete slab will be 4 inches deep, ideally the tubing would only be around 2 inches below the surface. The concrete pour was done in two halves. The concrete was poured from a cement truck and then spread around by 3 people inside the foundation. A roller was used to even out the concrete and make it level. (A track had been placed inisde the foundation so that the roller would stay at the correct height and make a level surface.) Some troweling was done by hand to smooth out the surface. A power trowel was used for most of the surface of the concrete, but it broke down mid way through the pour. The contractor brought another one to the site, but some drying in the concrete had happened and the surface ended up having a poor finish. (Some footprints were left in the concrete.) The excess concrete was used to make a step on the west side of the structure and a wheelchair ramp to the south. The concrete was wetted after the pour was finished and covered with tarps to slow the drying process.

Thurdsday - Timber frame work party

Dan and Marybeth enlisted help from the community for raising 4 beams on to their timber frame. Using scaffolding, we hauled the timbers up to the top of the framing and secured them into notches. These beams will complete the basic frame and allow us to continue with installing floor joists to build the second floor. In the afternoon I started work on a solar food dryer. The frame was made out of scrap 2x4s and was made to tilt toward the sun at approximately a 30 degree angle. A layer of sheet metal will be nailed onto the frame followed by a window screen that will hold the herbs, etc. to be dried. A window frame and black metal will form the top of the dryer and be hinged to the frame.

Friday - Bent construction

Ma'ikwe and I spent some time on Friday working on bent construction. (A bent is part of a timber frame that consists of several posts connected by timbers or lumber that is connected to them.) Clamps had been set up to hold the 2x12 lumber to the posts on both sides. We drilled 3/4 inch holes through the lumber and posts with an extra large drill bit. After the hole was drilled we cut a threaded-metal rod to size with a hacksaw. The rod was pounded through the lumber and post with a hammer and then secured on both sides of the bent with a washer and nut.

I spent the later part of the day doing inventory on the salvaged lumber that we will be using for framing and roofing. The wood planks vary slightly in width, thickness, and length. Part of the issue is that wood salvaged from older buildings is the actual size that it is stated to be. (A 2x12 plank purchased at a lumber yard is actually about 1 3/4 inches by 11 1/4 inches because 2x12 is the size before the wood is sawed and dried at the mill.) Some of our older lumber actually measures 2x12 inches while others measure 1 1/2 by 13 inches, 1 3/4 by 11 1/2 inches, etc. We will end up needing to "rip" some of the wood so that there is enough of the same size to use on a project. (Ripping is cutting lumber lengthwise so that it makes several pieces of lumber.) The length of the boards also ranges from anywhere from 16 feet to 26 feet, so more meticulous planning will be needed to calculate how many rafters can be cut from each piece.
