Primitive Technology: Barrel Tiled Shed

Digging a drainage trench around the building site Chopping timber for the frame Stuck on trees Stumps 2 months after cutting 14 months after cutting (from last year) hammering in a short piece of wood to form the post hole Putting the post in place Sharpening stone chisel carving a mortise Making a blow pipe This is the same wood I used for wattle frames in earlier huts. It’s hollow with a soft pith core.

Putting clay on to form a fire proof nozzle A small hole causes the air speed to increase Putting hot coals into the mortise Blowing the coals causes the mortise to burn and enlarge as well as fire hardening it to prevent the wood splitting. Scraping the burnt wood out of the mortise Horizontal beams in place Cutting lawyer cane with hand axe instead of hatchet (to save hatchet blade from damage on rocks). Lashing roof timbers with lawyercane Putting rafters on Tying rafters to beams (prevents posts from leaning inwards under weight). Frame complete Making lawyer cane basket The clay is in the creek next to the tile hut Digging firebox for kiln Green twigs form arch of firebox Clay from creek Mud forms the rest (to save precious clay) Floor of the kiln is 50 cm x 50 cm 16 holes are made in floor Holes are enlarged to ensure flames can get through Mud walls of kiln are about cm thick Having fire dries the layers faster Walls are 50 cm tall then are domed in slightly Making grate bars for fire box Grate bars help the wood burn more efficiently The kiln draws a fairly good draft Pick out stones and sticks Crush previous broken pottery and mix with clay to prevent clay from cracking.

Lawyer cane frame for tiles flat stone, tile frame and tile form wood ash to stop clay from sticking Clay is pressed into frame Shifted onto form Smoothed Set out to dry A batch of 30 tiles took less than a day to make But they kept being disolved in the rain and had to be shifted to the tile hut when semi dry Here they could dry near the fire out of the weather The under floor heating system helped speed up dryng When completely dry the tiles were stacked into the kiln Standing dead wood makes the best firewood Small sticks are the best fuel for kilns Broken tiles are put on to hold in the heat firing took 5 hours 2 columns of upside down tiles are laid with narrow ends pointing down into the tiles below to funnel water down the roof Then a column of right side up tiles are laid over the gaps with the narrow ends pointing up under the tiles above to keep water out of the gaps below The interlocking tiles stay in place due to weight and friction Remaking tiles that were disolved by rain before they could be fired 2nd firing: hours 3rd firing: hours A row of tiles was used to cover the gap at the ridge of the roof A scorpion came out of the roof due to the heat of the kiln 4th firing: hours (due to wet fire wood) 5th firing: hours A fire and water proof shed for future projects
