How To Make A Simple Wood Gas Stove (Large Version)
This stove is based on the downdraft principle and typically built with nested cylinders which provides high efficiency in the burning process. Combustion from the top creates a gasification zone with the gas escaping downwards through ports located at the base of the burner chamber. The gas mixes with additional incoming air to provide a secondary burn. Most of the CO produced by gasification is oxidized to CO2 in the secondary combustion cycle, therefore gasification stoves carry lower health risks than conventional cooking fires.
Getting Started
Materials:
- (1) 4 Liter/ 1Gallon Paint Can - Plain, Unfilled Type ($3-$5)
- (1) 1 Liter Apple Juice Can ($1)
- (1) Adjustable Metal Hose Clamp ($1.50)
- (1) Printed Template Of Drill Holes (Optional) (Basically Free)
Tools:
- Power Drill
- Step Drill Bit (1/16" to 3/4")
- Sharpie Pen
- Measuring Tape
- Can Opener (The One That Cuts On The Inside, Not Around The Outside)
- Screw Driver or Driver Bit
Take the lid of the paint can and use the apple can to trace out the centered position with your sharpie pen, like illustrated below. Now create a second circle inside the main circle you created with the apple juice can. Make this second circle smaller by 1/2" or 1-1/2cm.
Now draw lines connecting the circles together. Cut out the inner circle and then proceed to cut the lines up to the main circle. This with create tabs that will create a compression fit when we insert the apple can.
Step 2 - Marking the drill holes in paint can & apple juice can, then drilling them out.
You will only need to drill 14-3/4" holes just above the lip of the bottom of the paint can. You will need to use a step drill bit to cleanly achieve this. I recommend that you mark (14) 1-1/2" on center dots with your sharpie. This should give you approx 1/2" to 3/4" spacing between holes.
Your holes should look something like this, these are 3/4" holes. I didn't measure exactly, so my spacing was off a little bit and this doesn't affect performance.
You will need to take your can opener and open one end of the apple juice can, I would only use the can opener type that cuts open the top and not the side of the can, if you cut the side of the can you start to loose strength and can bend out of shape easily.
At the top of the apple juice can you will mark out 35-40 dots (1/16th drill bit holes) and mark them 1 inch down from the top to allow for the hose clamp and tabs from the paint can lid.
Now mark 8 dots (3/4 inch drill bit holes) spaced out approx 2 inches apart around the bottom side of the apple juice can.
You will need to make 60-80 dots (1/16th inch drill bit holes) on the bottom of the apple juice can. I wasn't able to make them perfect here but as long as you make a lot of them.
Step 3 - Putting It All Together
You will need to push the bottom end of the apple can through the top end of the paint can to make the tabs of the paint lid to catch and create the compression fit. You can do 1 of 2 things here, I seen people use cold weld compound to secure the lid to the apple juice can or like I did, I used a metal adjustable hose clamp. This way I don't have to worry about the compound break down over time or burning away after multiple uses at the camp site. Since the hose clamp is circular it holds the lid to the apple juice can very tightly and you can also swap out the apple juice can if it starts to get to rusty or fall apart after hundreds of burns.
After that you are pretty much ready to start your first fire in your new Wood Gas Stove!
You will need to hammer or pound in the lid to the paint can to securely fit into place.
When you start to place your wood you want to layer them by thickness. Place thick sticks approx. 1 inch thick and 2 inches long on the bottom. Then the next layer of sticks should be only 1/4 inch thick and the rest small twigs. To achieve the best results do not fill above the holes at the top of the can. These are the jets for the wood gas to feed the fire.
You will need to just start your fire from the top and not from the bottom as the heat from the fire on top will help release the gas from the wood and help draw it through the top holes to efficiently burn the wood inside.
As illustrated here you can start to see the wood gas coming through the top holes of the apple juice can.
Once you get the fire fully burning you will see all the jet holes burning nicely and effectively increasing the fire temperature and cleanly burning the smoke, wood gas and wood in your stove.
*******Notice Of First Time Burn********
Most paint cans these days come with a grey paint liner in them, so the first couple of burns you will need to burn off this grey liner and by doing so will produce a lot of black smoke. It took me approx three full burns to completely get rid of the liner. You may try to sand blast it off or use some kind of paint remover.
Tapping The Birch Part 2
Here is a list of the following items I used;
- Hand Drill Brace (power drill will work as well)
- Knife
- Bottle or Container (I used a Pepsi bottle)
- Rope (strap, wire or anything that will secure the bottle to the tree)
- Branch (hose, tap, metal tube can be use to direct the flow of sap to your container)
- Rag/Cloth
You need to first clear away the bark from the spot where you intend to drill your hole. Either peel or scrape away the bark with your knife. Use your knife to make a cut into the truck of the tree to make sure that sap is flowing.
I then found a branch and whittled down with my knife to fit my hole that I will make with my drill bit and I also notched out a small channel on the top to help direct the flow of sap into my bottle. My branch/twig measured approx. 4-5 inches and I scraped all the bark off so that it was smooth so there would be no resistance.
I drilled my hole with my brace (hand powered drill) at a 10 to 20 degree angle to further effect the direction of the flow of sap. I drilled my hole to a depth of 1-1/2" to 2" and continued to hammer/pound in my branch/twig until it was fully inserted.
I recommend that you bring a rag or cloth to wipe the area around your new branch spout as liquid tends to take the path of least resistance. It also helps to use your finger to wet your spout down the shaft with the sap to promote direction of flow. I found that the sap ran down both the bottom side and in the channel on the top and they both met at the tip to forum a drip.
Next I secured a length of rope around the neck of the bottle and left approx. 8 to 10 feet of slack so that I could wrap it around a couple of time so that it would not fall under it own weight when the bottle started to get half full.
You need to wrap the rope around the tree and with every second wrap I found I needed to wrap the rope over the top and then under the neck of the bottle on every second wrap to hold it in place and prevent the bottle slipping down the tree. Alternatively you could use straps or strips of Velcro to secure it to the tree.
I was in luck that a fallen stump was laying right next to the tree and I found a flat rock to make a stable base for my bottle. The roots of this stump laid right next to the tree and made things a lot easier.
I was able to collect 1750ml of sap in about 6 hours and filled the bottle in about 8 hours. After changing the bottle I was only able to get another 1/4 liter of sap in 12 hours. I proceeded to drill another hole 6-7 inch around the other side of the trunk and had similar results.
I would only suggest tapping the tree twice as you do not want to harm the tree and disrupt the natural flow of sap that the tree needs to grow and sprout leaves for the summer.
Please note that you need to remove the spout and stop the flow of sap by placing a plug made from a branch or twig. Your plug should be a larger than your hole to create a compression fit so that no sap can leak out. I never seen a tree die (bleed to death) from a open hole but if you want to tap the tree year after year a little prevention couldn't hurt. You also need to make it long enough to fill the cavity as well.
So what plans do I have with my collected sap, well I was going to try making Birch syrup but at this time I haven't collected enough, as the ratio is 100:1 for birch and only 40:1 for maple syrup. I plan to drink my 4 liters which is packed full of vitamins.
I will plan for next year harvest and try both maple and birch syrup processing. I hope this will help anybody looking to tap the birch tree in early spring.
Tapping The Birch
First on my list is tapping the sap from Birch Trees. I have been testing my birch trees for the last 3 weeks of March and no sign that the birch is producing sap. After having 5 days of rain and being the 1st of April, the birch trees are producing the clear watery sap that I have been waiting so long to collect.
Like sugar maples, the sap that travels up through birch trees in early spring is sweet and tasty. The predominant, naturally occurring sugar in birch syrup is fructose, as opposed to maple which contains primarily sucrose. Fructose, due to its chemical structure, is more easily digested and assimilated by the human body. Fructose has the lowest glycemic index of all sugars and can therefore be the most suitable sugar for use. Birch syrup is high in vitamins and minerals, including vitamin C, potassium, manganese, thiamine, and calcium. Native American Indians have long known of its medicinal benefits and have used it for centuries. The sap can be reduced down to a syrup; like maple syrup, brewed in to beer & wine or you can drink it straight from the tree.
The birch tree will produce this sap for approx. 4 weeks or until the leafs are in full bloom, this time period will shorten if the temps rise really quickly and stay stable during the spring which will lead to early sprouting of its leaves.
The tapping of birch trees and production of this syrup is growing in Alaska, birch tapping is not so common elsewhere. Perhaps it is because more than 100 gallons of birch sap are needed to make a single gallon of birch syrup; where as it only takes 40 gallons of maple sap to make a single gallon.
I will post some pictures in the next couple of days with a tutorial on how to tap birch trees.

Trees of Nova Scotia (Part 6)
While hemlock wood can be dressed for interior work, it most often used in rougher work such as bridge planks, sills, boxes and crates. Because this species retains its lower branches for many years, it wood is usually knotty. These knots probably contain the hardest wood of any eastern. They can nick an axe blade very easily. Hemlock is dangerous in camp fires, because it throws out more sparks than the wood of any other native conifer except perhaps cedar.
Early leather-makers leached hemlock bark for tannin, a dye and preservative. Indians poulticed sores and wounds with boiled and pounded inner bark. Settlers drank hemlock tea to induce sweating, and made brooms from the branch-lets
Elements of the Hemlock
Needles: Dark, shiny green and flattened, with two white lines below.
Cones: Similar to those of tamarack, but longer and not erect, pale green with slightly toothed scale margins, each fertile scale produces two winged seeds.
Bark: Reddish or greyish brown, changing with age from scaly or flaky to rough and deeply furrowed.
Wood: Buff with reddish tinge; tough ,splintery and fairly hard.
Trees of Nova Scotia (Part 5)
The Indians dug its long pliable roots for sewing birch bark on canoes and for decorating baskets. To prepare the slender roots they steamed coils of them for an hour or so in hot wood ashes, then removed and split them. Just before use, the roots were soaked in hot water. Examples of such spruce-root handicrafts can be seen in museums such as the Halifax museum.
Although some people use white spruce for Christmas trees, its value is lowered by the rank odor. Moreover, like other spruces it quickly sheds its needles indoors unless the butt is placed in water.
Elements of the White Spruce
Needles: Four-cornered, long, sharp-pointed, blue-green, mounted spirally on little pegs and usually crowding toward upper side of twig.
Cones: Pendent, longer than those of red or black spruce.
Bark: Thin, scaly, ash-brown to silvery; inner bark streaked with rust-brown layers.
Wood: Nearly white to pale yellowish brown, with faint white dots, lightweight, soft, straight-grained.
Trees of Nova Scotia (Part 4)
Red Spruce (Softwood)
This is our most valuable lumber and pulpwood species. Other uses include general construction, boxes and crates (because it imparts no taste to foods) boat-building, and ladder stock (where cross-grained wood is unsafe). The wood is often sold with the other two spruces as "spruce". On good sites it grows to 28m (92') tall and 0.3/0.6m (1'-2') in diameter. Normally the trunk is straight and fairly free of dead branches.
After balsam fir, red spruce is the most common softwood in Nova Scotia. Predominating in all but the Cape Breton uplands, and in western Nova Scotia. Nova Scotia's cool, moist climate ideal for the spruce, which also thrives in Prince Edward Island, New Brunswick and the New England States, and ranges south in scattered pockets through the Appalachians to Tennessee.
The small branches make a good , springy mat to place under balsam fir boughs when making a camp bed or survival shelter. (Place the spruce under-side up, the fir face up)
Elements of the Red Spruce
Needles: Four-cornered, long, bright yellow-green, sharp-pointed, attached to tiny pegs. (part of the twig, not of the needle as in fir and hemlock)
Cones: Pendent, green to purplish-green in September, turning reddish brown and opening the first autumn to release two winged seeds per fertile scale, falling in winter. Cone scale edges nearly smooth.
Bark: Finely scaly, thin, reddish brown; inner black brownish yellow.
Wood: Nearly white to pale yellowish brown, lightweight, straight-grained, fairly strong, grain slightly more pronounced than in white or black spruce.
Dressing in Layers for Winter or Cold Weather.
Why should you dress in layers? The reason is that you can easily adjust or remove clothing to manage and achieve the best temperature that is comfortable depending on your level of activity or weather conditions to prevent sweating.
When you are in freezing temperatures and you being to sweat heavily, you become wet and heat transfer is greatly increased and can lead to hypothermia. "Sweat Can Kill You" in cold temperatures.
Base Layer:
A high quality base layer is really important part of the layering system. The base layer helps manage the moisture levels and helps wick sweat away from your body. The best materials for base layers are fleece or other synthetic material. Another popular natural material is wool and especially Merino wool, this type of wool is soft and less itchy then traditional wool and can still retain most of your body warmth even when wet. Wool can also be especially good around fires, as they don't melt from sparks or flying embers unlike its synthetic counterpart. Look for long sleeved shirt tops and long johns for the rest of your body.
Do not use cotton material in your base layer as cotton traps the sweat and holds moisture next to your skin. "Cotton Kills" in a survival situation.
Mid-Layer:
The mid-layer is used to protect you from the cold by trapping the heat and keeping it close to your body. Once again fleece or wool clothing is great as a mid-layer and also find clothing that can be zipped up from the front for easy removal or to easily vent off access heat without having to strip off layers.
Shell Layer:
The shell layer keeps out the wind, rain and snow. Shell layers come in a variety of materials and styles; such as windproof fleeces, winter jackets, ski Jackets etc. Also consider breath-ability to help release the moisture. Gortex is one of the newest materials that offer waterproofness and the ability to release the moisture from the inside out.
If you do not protect your fingers, your chances of frostbite will greatly increase with extremely low temperatures and can cause a dangerous situation. You can start off with gloves that are not too thick as you will cover them with larger mittens. The layers system works well here, having the flexibility of gloves; that keeps your fingers protected from the elements and still have the dexterity to do tasks is a bonus when paired up with mittens. Mittens are best for warmth but are limiting in more precise tasks. You essentially are taking the pros and cons of gloves and mittens and making them both pros in the end.
Head:
A lot of heat can be lost from your head; so it’s important to have it covered up. Using a toque or head piece with ear flaps (Like the Russian Hats, I forget what they are called) can greatly improve comfort. Other Accessories like a scarf or Merino Wool Balaclava (Ski Mask) to completely cover the face, ears and head. Keep it simple and get it in wool or fleece.
Feet & Legs:
Winter boots are best in winter or sub-zero conditions, Hiking boots are not recommended in winter conditions as they lack the material to keep your feet warm in extended hikes or trips. Socks should again be wool or synthetic. Also consider liner socks; these fitted socks feature fabric technology that lets yarns next to the skin wick moisture to the outer sock to help keep your foot drier and warmer. By allowing some of the friction caused by walking to take place between the liner sock and the main sock, liner socks may also help reduce blistering. Always bring extra socks in waterproof containers or bags as increased activity can create a lot of sweat in the foot area.
You should have a good warm, windproof, snow/waterproof pair of winter pants. Ski pants are ideal for many winter activities and offer an all in one package for protection of your legs. If you don’t have access to ski pants, use thermal wool long johns , fleece jogging pants and some kind of waterproof/wind breaking material to help protect your legs.
The information above is some suggestions on how to dress for winter. Please do more research and do your homework when developing the layer system that works for you. Different situations will require different layering methods.
Thanks again for taking the time to read my blog and I hope this information helps you folks. If you have any suggestion please leave a comment.
The Survivalist Blog - Free Downloadable Ebook (A Must Have)
I have been a avid reader of M.D Creekmore and the survivalist blog. What I like about his blog is it's down to earth and is a perspective of the everyday person preparing for everything and sharing his experiences along the way.
There is an ever growing trend for preparing for "TEOTWAWKI" (The End Of The World As We Know It) and being prepared for natural, economical and/or political disaster is not a bad idea. You can start small and eventually build enough supplies to last 6 months, 1 year, 5 years or even 10 years. Such supplies include water, food, basic gear and medical supplies. When things start to fall apart these simple items can start to get hard to come buy. I find it funny when the first large snow fall hits and everyone is scrambling to get shovels at the hardware store and they are sold out in minutes, just imagine if something bigger or more serious happens and the power is out for weeks and stores are closed, most people would be shit out of luck.
So how does one start preparing? Well M.D Creekmore has done a lot of the research and posted numerous articles on his blog which he has packed into to his new Survival Ebook to help anyone with questions on how to start preparing for the unexpected. His new ebook " Its the end of the world as we know and I feel fine" is a collection of the most important things to consider when preparing for the end of the world or some kind of disaster.
I think M.D Creekmore has done a fabulous job in creating a great reference material that should be added to your library or collection of books. What I like the most about his ebook is that he has laid out the every basics. My favorite section is the food storage and how to prepare, what food are best to store and how to store them. The diagrams outlining food shelf-life is a bonus, M.D. Creekmore has created simple lists of gear that people should consider in there stockpile.
Even if your not into TEOTWAWKI I would suggest that you read it, you never know when this kind of knowledge will save your life! You can download it for free from his website or click on this link to download his ebook now.
Trees of Nova Scotia (Part 3)
A fast-growing tree that tolerates no shade, this species is often forced by shade-tolerant species to inhabit poor open sites such as peat bogs and swamps. Rabbits like the needles, and ruffed grouse and other birds eat the seeds. The branchlets are sometimes browsed by deer. Porcupines seem to prefer its bark to that of most other softwoods species.
Boatbuilders still use tamarack to make the curved bow piece that fastens to the keel to receive the forward planking; here strength is essential. But today tamarack is cut chiefly for fence posts, poles, and ties. The wood is said to last over 15 years underground without preservatives. Most softwood posts rot within 3 years. As a fuel wood its gives off great heat but the creosote content are hard on stoves and stove pipes.
Elements of the Tamarack
Needles: Soft, blue green (turning gold/yellow in the autumn) ; in clusters of 12 to 30 needles on older twigs, but singly on new shoots.
Cones: Upwright, short-stalked, thin scaled, light brown, resembling a miniature, oblong rose; opening the first fall to drop seeds, falling the second season; bearing two winged seeds per fertile scale.
Bark: Thin, in young trees a smooth bluish-grey, later red-brown and roughened by fine scales.
Wood: The heaviest and hardest of native softwoods; white to yellow-brown and more or less oily.
New Hiking Gaiters
Well did I come across a great item, gaiters for my hiking boots. If you don't know or never heard of gaiters they are protective covers for your foot wear. when you are out in the bush you should always have a good quality hiking boots and joining the boots with a set of compatible gaiters, creates a good outdoor footwear combination. They will help keep out small rocks, pine needles, debris, snow and anything that finds a way into your hiking boot. The impact of an accidental step into a mud hole/water hole is reduced when wearing gaiters and do a good job of keeping the mud out. Also walking in the rain feels much better with gaiters forming a cover over the top of the hiking boot.
I bought these Gortex Gaiters on ebay and was surprise with the quality and price. I ended up paying $17.00 CND altogether with shipping included.
There are a few features I liked when I found these; firstly they were made of Gortex, which makes them water proof and breathable. Secondly instead of a big leather strap to secure the gaiters to my boot, you can use a shoe lace or 550 paracord. I think this is a great feature because the straps on other gaiters can wear away pretty fast if moving over rough terrain like rocks and such. You could be looking at $5.00 for each replacement strap. That can add up over time, where 550 paracord or shoe laces are a fraction of the cost. Also I probably won't carry a replacement strap in my pack as I already have enough gear in there, so being able to use rope or shoes laces to secure my gaiters is a win, win situation. If for some reason I lose my pack which has my 100 feet of 550 paracord I know that there always some right at my feet.
Typically gaiters can run you any wheres from $30.00 to $75.00, that being said these gaiters are not the end all or be all either. I myself think that for $17.00, is a good bang for your buck and if I do end up destroying or ripping these gaiters up, I won't feel bad cause I know it won't be expensive to replace.
Here is a link to the gaiters I bought on ebay;
Ebay Seller: manda_1213 (99.5% Positive Feedback)
Ebay Item Link: http://cgi.ebay.ca/Gore-Tex-Waterproof-Hiking-Walking-Legging-Gaiters-B_W0QQitemZ320471470309QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item4a9d9690e5
Shipping for me in Nova Scotia was about 1-1/2 weeks, not bad for being shipped from china.
I hope this post will help someone complete their gear or improve their hiking experience with gaiters.
Thank you for taking the time to read my blog today,

Show and Tell
I thought this would be a fun post to see what everyone has gotten under their tree this Christmas. I'll start with what I got this Christmas and post my review of each item.
Leatherman Surge Multi-Tool
I did a lot of research on Multi-tools and I kept coming back to leatherman over any other brand that I have found. I have had several of the cheap mutli-tools over the years and have broken them all.
I replaced the cheap Mutli-tools with a small Swiss Army knife and I can't count how many times I have used it. I have been using my Swiss Army knife for the past 3 years. I have recently been doing things that require certain tools that my Swiss Army knife could not provide.
In my search for the mutli-tool that had the tools I needed, I found the Leatherman Surge that had almost every tool I needed on a daily basis. I need a mutli-tool that I could use at home, work and in the woods.
Things I look for in a mutli purpose knife/tool are; for more information please visit their website Leatherman.com
- Large Blade & Small Blade
- Scissors
- Pliers
- Philips & Flat Head (Small & Large)
- Metal File
- Wood Saw
In Canada the Leatherman Surge runs between $100 -$115 in most retail stores.
MEC High Camp Cookset
The high camp cookset is really nice for the price. This set will run you $35.00 at the Mountain Equipment Co-Op website or in-store.
These pots feature bail handles with stainless steel rivets, stepped bottoms to prevent warping, and lids that double as frying pans. These lids are rounded for easier cleaning. An aluminum pot gripper is included. I really like this gripper, its extremely light weight and can be used on the lid/frying pan or pots. This cookware set would feed 2-3 people depending on the food made.
This is a lightweight set, that I will put to good use. Having not used any other cook sets like Zebra or similar. I will definitely find out this spring and summer when I head out in to the woods.
I also received socks, clothing etc... not anything that is bushcraft/wilderness survival/camping or otherwise related items. I will post my survival pack and the items I do carry with me in a later post and also any new items that I might come across.
Thank you for reading, I hope you have enjoyed my blog.

Trees of Nova Scotia (Part 2)
Elements of the Red Pine
Needles: The needles are in pairs of 2 and they are long, dark, yellow green in color and not twisted as in Jack pine.
Cones: Oval in shape and maturing in two years, they are much smaller then their white pine counter part. When the cones are mature they will be hanging and chestnut brown, and will open to release their winged seeds.
Bark: Orange-brown and flaky on the young trees, later breaking into flat red-brown plates.
Wood: Yellowish to reddish with a pronounced grain. Lightweight, straight-grained, heavier and harder than white pine; takes creosote very well, has fine dots in growth rings.
