Boiler Feed - Australian Hardwood for a Scottish Boiler
« on: April 08, 2015, 10:56:06 pm »

Guys.......whilst clearing fallen tree branches from the Illawarra Live Steamers 5" gauge tracks....... I spied  :o a few branches that appeared to have a significant number of growth rings, however were still relatively small in diameter

So for my ACS Scottish boiler I needed a few piles of rough sawn Australian hardwood logs and @ 1:20 scale would need to be

~~~ 6 to 12 mm diameter
~~~ 50 mm long
~~~ with say 1/2 a dozen growth rings to represent age

Not sure of the botanical name of the specie.... ;)....but the results speak for themselves.....seems a shame to burn them..... Derek {-)

PS...so whilst we don't know which year the wood will be burnt.......they can rest on the drying tables which will also increase the calorific heat value/output due to the reduction of moisture

Now I wonder if Sandy has a calculation for such timber dryness?....... to be used in his gas fired  boiler >>:-(........

They could pass muster as plantation pine which are harvested at the 20 year mark, AKA the number of growth rings

 ;)....thanks for the advice & I tend to agree  RAAArtyGunner...that timber logging merchant didn't know the difference between hardwood & softwood  >>:-(

Have sacked that person & ordered a new batch of 'geuineen' OZ redwood  :-)) probably from the Bramah forests  bordering the Murray river 100 years ago...... :embarrassed:

Interestingly, the logs look about the same size {-)  .......which is good......... Derek

To get serious, the bark is a dead giveaway for pine timbers.

The Hardwoods will burn better.
