(Part 5) Tinder Ignition - Continued
9.jpg10.jpgHorses hoof fungus. The horses hoof (or false tinder fungus) grows on dead Birch trees. It has three distinct layers - a very thin crusty outer layer, a thin (1 or 2 mm) leathery layer of amadou and a thick corky spore layer. The crusty outer and spore layer need to be removed and the leathery layer either dried and roughed up with a knife blade or boiled in wood ash, pounded and fluffed which some claim improves the fire taking qualities.

Prepared chagga fungus
True tinder fungus or chagga. Chagga fungus looks like a black lumpy burr on the side of a birch tree. Dried and crumbled it makes excellent tinder and is particularly effective in fire pistons.

Punk wood: Punk wood is the soft powdery wood found in the middle of rotten logs that is almost as light as balsa wood. It can often be found dry by knocking or kicking apart rotten logs. Be sure to dry it or dry out damp stuff before needed. It light very easily since its well mixed with air already. If charred like char cloth it will catch and burn from a cool spark.

Feather stick: In making a feather stick, fine curls of wood are shaved from a dry stick leaving them attached to the main stick. The finer the curl, the easier they are to ignite – some practice is required to get good and quick at this. I have had excellent results by using an axe to split a wet log to get to the dry wood inside, chopping thing pieces of dry wood and then feathering them. A finely feathered stick can be lit with a match – a very well made one ignited with a spark from a ferrocium rod.

The cooler trusty "zippo"
Petrol: Petrol vapour (liquid petrol doesn’t burn – just the vapour) is what powers the trusty Zippo lighter.

Photography - Back to Basics (08.12.2008)

thumb_k10d.jpg We all love to take photographs and keep a record of what we've done and where we have been.  Michelle Jones  has written this article is for those starting out into photography so that you can get the most from your camera and what you are trying to capture.

Fish Trap (01.04.2008)
thumb_fishtrap9.jpgI used Hazel wood. Choose the thin long shoots of wood which i would think are a couple of years old. If you don't catch anything at first don't worry. It may just be a case of changing a few things.
Birch Tar - How to collect it (23.02.2008)

Wild Wine (Part 8) (28.11.2007)
thumb_wildwine6.jpgNow we could bung a label on (which should always say they type of wine and when it was bottled). I suggest you cross-reference to a book of recipes and notes so that when you get a cracking wine you can recreate it. We are going to add a little something to the presentation of the wine by putting a foil cap over the neck. First we drop a foil cap (available for a couple of pence from a wine shop) over the bottle neck.
Wild Wine (Part 7) (26.11.2007)
thumb_wildwine1.jpgRight, we now have clean, fined and filtered wine. We pour it into clean (yes and sterilised) bottles with a funnel. We need to cork it. Its possible to put corks in with a mallet. I use a corking gun and waxed corks that do not need to be soaked (plain corks do)

thumb_wildwine1.jpgWell, the finings have worked – the wine is beautifully clear.

Paracord Bracelet Tutorial (23.04.2007)
thumb_paracordbracelet16.jpgAs soon as I'd finished my Paracord Bracelet, I'd decided to write a tutorial on making one. A good thing considering the majority of the responses since I posted it were asking me how to do it! Here goes..

The techniques used in here are intended to provide not only a sharp axe but also a safe and efficient axe.

Fire By Friction - Using a fire-kit made with stone tools (31.05.2007)
thumb_firefrictionwhitcombe2.jpgThe whole kit took less than three hours to finally pull together — though that really overlooks by far the most time-consuming aspect, the preparation of materials. In fact, preparation has two components, actually. The first is the selection of materials. The second is the actual preparation.
