This is a Finnish blog where I present an unlimited set of ideas among others of low-tech inventions, sustainable living and ways of doing things, preserving vegetables and some art, too.
Would you like to read some of the content in English?
I’m happy to create English versions of the posts, if there’s a demand for them. On this page you can take a look at the brief descriptions of the posts. Then you can let me know what you’d like to have in English and maybe write list of them sorted by priority. Please contact me through the form below:
Turning machine for small round timber: Ideas of a machine which could peel small diameter (probably 4-13 cm, 1½”-5″) round timber and turn it round. Timber is pushed all the way through the machine. Timber doesn’t spin, but a blade plate, that holds the blades, spins around timber. It is suspended with rolls. Timber could be turned into certain diameter or with a certain cutting depth, the latter to save as much wood as possible, and to use less power and time. This machine could work in the forest or at a sawmill, for example. In the case of turning timber in the forest, turned rods could be dried in some kind of racks in the forest thus leaving more nutrients (the most are in the branches anyway) right on the spot and minimizing the weight to be hauled out.
Compost(heat): Thoughts about combining composting of all kinds of materials from the manure of animals and humans to kitchen waste and twigs, cycle of nutrients, biochar, demand for warm water and firewood (which would be reduced) and gardening into a symbiotic arrangement.
Conewave: A conewave is a geometry, in which cones are positioned so that each cone cuts back two neighbouring cones as well as is cut back by two other neighbouring cones. The tips of all the cones lie in the same center point. Four cones allways touch each other at one radial line from the center. In the post I tell a bit about the mathematics behind conewave. I also play with application ideas of conewave like: graphics, some possible ways of interaction of two (or maybe more) conewaves, conewave projected on surfaces, conewave as a synthetical musical instrument (in principle it could even be made into a mobile app) etc.
Cladding idea: Installing cladding at 45 degrees angle in respect to edges, to make boards of all three surfaces meet beautifully in the corners. Then ideas of how to create areas and shapes in the cladding, where the direction of cladding boards is perpendicular to that on the other side of the border. Grinding grooves and making DIY bending plywood strips that connect the pieces of cladding.
Bike trailers: Presenting two bike trailers with different properties and materials. My experiences with them and plans of development and modifications.
Tricks and techniques: At the moment in this post there is a number of tips and tricks for amateurs in metal work.
Thingies’ collection: Some tips on, for example, how to tweak some items, tools and machines to make them serve better.
Pressing plate and center tube for fermentation vessel: Fermentation of vegetables, for example, making sauerkraut, requires anaerobic conditions and creates carbon dioxide gas. One practical way of keeping the ferment under the surface, safely out of any oxygen, is a pierced stainless steel plate. The lid holds it down. Produced gas expands the volume and raises the surface until it gets out of the liquid. The pierced center tube shortens the distance for the gas to get out freely, so the surface won’t rise so much (sometimes it could even get out of the vessel and make a mess).
4WD for short distances: In case your 2WD car can’t move in a slippery place, it may be possible to connect the free turning wheels to drive wheels with some nonelastic belts. Then you have a kind of a four wheel drive! It is only possible to drive one fourth or at most one third revolution at a time – you must not let the belt move too close to the hub, because that would cause dangerously great forces. Actually the connection point on the drive wheel has to be a bit further in the direction of rotation, to go around the death center before the free turning wheel.
Transport wheels mounted: I mounted transport wheels to a carpenter’s bench and a table of a little circular saw. In both tables the wheels can be easily tilted on and off for moving and use.
A cutting rack for vegetables: A rack that is packed full of vegetables like nettle, that are easier to cut compacted. Then the mass is cut with knife through each or possibly fewer gaps between laths. Some tips on construction.
Scraper with adjustable curvature: Adjustable curvature allows to scrape powerfully on more narrow a strip or more gently on a wider strip. Most often this kind of scraper works for removing paint or similar tasks, but sometimes it might also work for finishing concave surface.
Extra clip for measuring tape: This simple thing makes pushing the measuring tape’s clip over the edge of pocket SO MUCH EASIER!
Soaking buckets: It’s practical to do stacked inside each other, filled with washing solution.
Drying of rubber boots: Ventilation hose or pipe enhances air flow in and out of boot, so it dries more quickly. Included in this post are a couple of other tips for efficient drying and how temperature and relative humidity of air affect drying.
A crank funnel for a spice mill: Sketches of an accessory for a good spice mill to make it serve much more conveniently and efficiently: so the spice container could be replaced with quite a wide funnel, on the edge of which there is a knob, so one could grind small amounts of many different spices.
Corking bottles with a drill press: A corking tool’s cap was fixed to the chuck of a drill press to be able to cork bottles with collars of different lengths. The corking tool could only grip a collar of certain length, but drill press doesn’t need to grip anything, but only to press downwards, which it does very well!
Modification of a hand drill’s press stand: To enhance functionality I made a separate height adjustment rod for the press stand of an old Black&Decker hand drill.
End grain cutting boards: Mostly presenting variations of one type of design.
A keg / pressure vessel: Made out of the pressure vessel of a pressure water automaton. It’s fixed to a stand and rotates with a wooden ball bearing to allow tapping and refilling. Done as well as undone ideas about possible applications.
Refreshing bread: If bread has dried, I refresh it by placing it under a bowl with a plate or cup filled with water. Water vapour moisturizes and refreshes the bread. Also included a sketch of a bread box with water vessels and a tray with crumb collectors.
Advanced wire brush: An old but efficient wire brush. It has an adjustment plate within the wire bundles. The plate can be moved between the tips and bases to leave desired free length of wire bundle. The closer to the tips the plate is, the harder the brush is.
Making berry pyree: It can be done with a meat mincer, too.
Wave cone lump: Idea of a material for decorative purposes. Intersecting wooden cones glued together. Thoughts about options for the production process, that wouldn’t require a CNC machine. Actually possible geometry is described in the post conewave.
Spontaneous fridge: Could a fridge be cooled with a spontaneous process, in which evaporating water creates the cool? Air flows should happen by gravity. I am thinking how heating and cooling and evaporation and condensation could be connected together to create the effect, but I don’t know what dimensions the parts should have to work efficiently together.
Supporting berry bushes: Bend some elastic bar around the bush. Stick rods around bushes and hang the bar from them with cords. This way the undersides of bushes are left somewhat free for lawn mover or the use of a harvesting canvas. Thoughts about how to make the bar out of willows by weaving them into a continuous wattle.
Apple pipe: A tool for removing kernel and sectioning maybe 10-20 apples at time by one push through the machine. A few design options, hand drawn as well as CAD images.
Flattening a tin can’s edge: Useful how-to of rolling a piece of tube inside a tin can against solid surface to flatten the sharp edge. After flattening the edge a can is ready for use and there’s no need for extra patience or plaster.
Processing table: It’s designed primarily for kitchen, but is surely usable in other applications, too. All of the table’s surface would be cutting board. There’d be a bowl roulette under it, and holes for pushing chopped ingredients into the bowls. Thoughts about possible designs and materials.
String reels: A deft design for a string reel and an adjustable spooling bench. A tip for cutting circles with hole saw in a drill press.
Right angles: A probably surprising way of making a carpenter’s square or something like that.
Vegetable dryer: Here’s presented a dryer that is a tube of stacked rectangular board frames, in which the grids are placed. Heated air is blown from the bottom and it passes through the grids drying the foods. The lowest grid dries first, it is taken away, emptied, filled with fresh stuff and placed on top of the stack. Also included among others building tips, experimental knowledge of this and a bit of theoretical review. A cabinet dryer with wood stove is now presented briefly on carrot project’s page.
Plywood boxes: A variety of different plywood boxes made using mostly a V-shaped adhesive seam. It has proved to be a great compromise of simple manufacturing, strength and good looks. You’ll find a lot of deft features and tips!
Stove cord: This loop of steel cord is a great help when cooking on iron plate of a basic electric or wood stove. When the pot has been brought to a boil and you switch power off, but the plate would heat too much for a while, you can put cord under the pot and keep it from boiling over. And in case even the smallest power is too much, using the cord you can simmer foods gently.
Inner tube loops: Durable and handy rubber string loops can be made out of used inner tubes of all vehicles. A paper guillotine has proved to be a useful machine for cutting the bigger tubes.
Support frame for a chopping block: A prototype of a buoyant frame that keeps wood steadily on the block, but backs down when chips spread or the axe hits the support. So worker can easily, rhythmically at best, chop all the wood without needing to pick them and put back on the block. This prototype has potential, but I am not yet sure, how this needs to be changed to be actually good and lasting construction.. Here’s also presented forming of those PVC tubes with heat.
Sawing rack: With this rack it’s easy, safe and efficient to cut a bunch of wood with chainsaw. Besides the made model there are some alternative design and construction ideas.
