Chainsawing Mulga and other very hard woods
Chainsawing Mulga and other very hard woods
Hi, I have had an enquiry about cutting Mulga and other very hard woods with chainsaws
The enquiry
"milling Mulga in the Gibson Desert region of WA – Ngaanyatjarra lands in particular.
You probably know Mulga is very hard, similar to the Lancewood or Gidgee found in the Gulf country, North Queensland and Mornington Island. (I once sent a sample from Mornington to AEG in Germany – they couldn’t believe how fast we went through their planer blades – their reply was “our blades are for wood, not metal!”…
Anyway, would you mind recommending the best chainsaws, milling blades etc in your experience.
The logs to be milled here are typically between 150mm – 250mm diameter and lengths vary a lot. Trees are casualties of bush fires… we go to recently burnt country and cut the straightest we can find. Chainsaw blades last ok when crosscutting… regular touch-ups help… but any older hardened wood is avoided – blunts a blade in no time."
I am inclined to think that tungsten tipped blades are probably the best thing but I do not know where to locate them nor can I offer advice on the best ohainsaws to buy. Although I do prefer Husqvarna/Jonsered over other brands
So what do the forumites think?

Mulga is not that much harder than Wandoo and given they are small logs I don't think it is necessary to go to carbide.
I would use a freshly sharpened chain with rakers set in a progressive manner and touch up often, at least after every tank full of petrol or maybe more.
In logs that size I would be looking at 0.050"3/8 Lopro chain as it has a narrower kerf which reduces the load on a engine. Only problem with Lopro is that conventional 3/8 drive sprockets don't fit so you either have to roll your own or get them from the US.
