    Hike Like a Pro With These 6 Tips

    Good tips, thanks.I look at hiking poles as almost like having a hand-rail built into the mountain. You can steady yourself when the ground is uneven, pull yourself up when you need to make a steep step, and lessen the impact when having to make a steep step down.

  • Firewood Log Tea Light With Matchbox

    The wood looked slightly 'diseased' (sorry - not meant to be a criticism, adds to the rustic charm) but I guess that may allow some of the stresses from the drying out to relieve themselves without cracking. I watched a demonstration of 'bodging' (ancient method of making objects like table and chair legs out of forest timber) and the first thing the guy did was take a large log, then split it into wedge-shaped quarters using a 'froe' (lovely old tool). Then he laboriously made those quarters into rough cylinders before turning them on the primitive lathe. One of the kids I was with asked the obvious question "Why not start with smaller branches as they are already almost the correct circular cross section and diameter?" - but the reason was that the way circular logs dry out...

One of the kids I was with asked the obvious question "Why not start with smaller branches as they are already almost the correct circular cross section and diameter?" - but the reason was that the way circular logs dry out - from the outside first - means that they end up splitting. The outer layers dry out and try to shrink, but they are prevented from shrinking by the inner parts that are still damp, so the only way for it to happen is for the wood to split in radial lines.

    Bicycle Mobile Charger

    Many years ago I had a bike with a purpose-built dynamo (6V @ 3A, AC). I rigged it with rectifiers and a three-way switch so I could charge up my lights during the day and have them good and bright, even when I stopped at junctions. This was a long time ago - before LED lights - so batteries for normal bike lights never lasted long.But after running fine for about three months I suddenly had a blow-out. The dynamo had worn through the tire sidewall.

    Homework Writing Machine

    In fact it was one of these: http://munk.org/typecast/2016/11/19/the-handwriting-drawing-typewriter-brother-type-o-graph-bp-30-with-user-manual/

    About 35 years ago, I had a commercial one of these - made by Brother, the typewriter people - it was basically a typewriter that used small ballpoint pens to draw the letters, and if I remember correctly, it could change font sizes (but not the font itself). It could also draw simple bar charts, pie charts, line graphs, etc. But after a few years it was impossible to find refills for the pens (this was pre-internet!)So well done for making a more usable version :-D

    5 Ways to Remove a Stripped Screw

    Any easy way to do this with a slotted screw apart from making a new slot like your Step 4? I had one where the head had broke in half. I tried drilling a hole for a screw extractor but it just disintegrated leaving a little stump sticking out. Luckily I didn't need to reuse the same screw hole so I used a 'Manchester screwdriver' (aka a hammer) to bury the stump into the wood.

    Rabbet Plane From Bench Chisel

    This is a really good idea. I wonder if it would be possible to make it adjustable, so you could use chisels of different widths? So instead of gluing it together you could bolt it. And use a different thickness of wood for the sole part to match each chisel?

  • Make a Paper Transforming Geode Cube - Design and Template

    There is a modular origami version of this by an English man called David Brill - a 'double-star flexicube' - https://brilliantorigami.com/diagrams/It makes two of these which can nest inside each other - which I guess you could do with this also.

    Make your own charcoal at home (Video)

    You can make 'char-cloth' in the same way. Char-cloth is like charcoal, but made out of cotton cloth - like a piece of old jeans fabric, or an old cotton t-shirt. It's great for lighting fires in survival-type situations. You can get a great big hot ember easily from a spark or a magnifying glass.
