Lin you say your not the best fire maker so how about we work on that first.
Fire needs 2 things fuel and AIR, If the wood you buy is seasoned (plenty of servo wood isnt dry enough) then I suspect you are not getting enough air into your fire. The key to a good fire is coals because coals make heat, hot air rises causing air to get sucked into your fire. When you are putting your wood on never put 2 bits side by side close to each other, forget the pictures you see of nice neat tee pee style fires, they are ok for getting the fire going with the lighter wood but once burning put your wood on randomly but with plenty of air gaps, picture a Zenga stack (that stackable timber game where you pull out bits, that would burn really well
As for where to get wood, the problem with the servo wood is its a bit short and compressers your fire. A bag of that wood is handy to have but I would rather gather it beside the road from fallen branches. You need stuff from about the size of a match to stuff the size of your arm and about an arms length is good. If you have stuff that is too long find 2 trees or a fork in the tree to break it, or do as I do if I havent got the chainsaw, drive over it with the landcruiser
. If the branch bends its not dry, dry wood burns wet wood smoulders
The small match sticks are for starting and then you build up in size and as long as you have plenty of air getting in you can build up in size quickly.
Ps if you need to use an excellerant to start a fire please use kero NOT petrol.
