building the woodshop
Bookmarked 532 weeks ago
this is about how i built my wood shop we decided to move from our previous home for a variety of reasons i saw the move as an opportunity to gain a bigger shop for my wood working hobby the house we found had everything we wanted except for a shop or even a garage it did have a non functioning indoor pool we thought this space would make a nice wood shop i could just build a floor over the pool and have a shop as we got further into the inspection process it was looking as though fixing the structure over the pool was going to be expensive it looked like we would have to put a bunch of money into a structure that was not really a wood shop and not a functioning pool either it made more sense to take out the pool and structure and then build a wood shop from the ground up we started this project by regrading our side yard to gain access to the pool in the backyard once we had access we took out the pool we half filled the hole where the pool was with compacted gravel i realized that if we sank the shop into the ground i could have the ceiling height i had always wanted in the shop and preserve the view from the house the design of the shop is a box with a shed roof the roof wraps down the east side of the structure i like to think of it as a slightly open toolbox the entire shop is laid out on a 24 inch grid the windows and doors fall within this grid i had a general contractor built the shell and then i built the windows and interior the interior walls are comprised of a 34 inch concrete stem wall at the base above that is a 9 foot plywood wall in the space above the plywood wall and below the shed roof is poly carbonate panel to form a clerestory the tool layout in the shop is divided into 4 areas: an area near the door for material storage and prep a central area for general wood working and two areas near the back of the shop one for turning and one for metal workingwoodshop tour: http:youtubexmdainbnpyqband saw video: http:youtubejuphdlunwjgjointer video: http:youtubel55yfrhbgx4http:wwwfrankmakescom

primitive technology: a frame hut
Bookmarked 414 weeks ago
i built an a frame hut as a large work space for projects first i made a celt hatchet to cut timber for the hut the axe head was made of amphibolite and the handle was made of a species of wattle for the hut the floor plan was 4 x 4m the height of the ridgeline was 2 m above the ground a post was planted in the ground to support the ridge pole at the back of the structure and an a frame was put in the front to support the ridgeline the rafters of the hut were then attached to the ridgepole palm fronds were then collected split and lashed to this frame the dome hut was disassembled and its thatch was added to the structure approximately 1200 fronds were used in total for the ridgeline thatch was lifted in place and rested on without lashing it down instead pairs of sticks lashed together were lifted in place sitting over thatch preventing it from blowing away these are known as jockeys as they resemble a rider sitting on a horsea wall of wattle and daub was built at the back of the stru

building a tiled roof hut
Bookmarked 538 weeks ago
i built this tiled roof hut in the bush using only primitive tools and materials the tools i used have been made in my previous videos it should be pointed out that i do not live in the wild and that this is just a hobby it should be obvious to most that this is not a survival shelter but an experiment in primitive building technologyto cut and carve wood i used the celt stone axe and stone chisel made in this video https:wwwyoutubecomwatchv=bn-34jfurhy to carry water and make fire i used pots and fire sticks made in this video https:wwwyoutubecomwatchv=nckkhqlx9de finally to store fire wood and dry unfired tiles i used the wood shed built in this video https:wwwyoutubecomwatchv=zajpkwdeeyg the wooden frame was built with a 2x2m floor plan and a 2m tall ridge line with 1m tall side walls 6 posts were put into the ground 025 m deep the 3 horizontal roof beams were attached to these using mortise and tenon joints carved with a stone chisel the rest of the frame was lashed together with lawyer cane strips the frame swayed a little when pushed so later triangular bracing was added to stop this also when the mud wall was built it enveloped the posts and stopped them moving altogethera small kiln was built of mud from the ground and a perforated floor of clay from the creek bank tiles were made from clay pressed into rectangular moulds made from strips of lawyer cane 20 tiles were fired at a time 450 flat tiles and 15 curved ridge tiles were made with only a few breakages 26 firings were done in all and the average firing took about 4 hours the fired tiles were then hooked over the horizontal roof battensan underfloor heating system was built into one side of the hut to act as a sittingsleeping platform in cold weather this was inspired by the korean ondol or hot stone a trench was dug and covered with flat stones with a firebox at one end and a chimney at the other for draft the flames travelled beneath the floor heating it after firing it for a while the stones stay warm all night with heat conducted directly to the sleeping occupant and radiating into the roomthe wall was made of clayey mud and stone a stone footing was laid down and over this a wall of mud was built to save on mud stones were included into later wall courses the mud was dug from a pit in front of the hut and left a large hole with a volume of about 25 cubic metres the finished hut has a swinging door made of sticks the inside is dark so i made a torch from tree resin a broken tile with resin on it acts as a small lamp producing a lot of light and little smoke the end product was a solid little hut that should be fire and rot resistant the whole project took 102 days but would have taken 66 days were it not for unseasonal rain for a more in depth description see my blog https:primitivetechnologywordpresscom
