Preparing Timber

Windy Moor Project

Wednesday 13 December 2017
Part of the project to install a boardwalk over Windy Moor is to stain the timber it will be built from. The reason for this is a desire of the park management to make it blend in with the environment and the colour chosen was chocolate.
After milling and being treated with preservative, the timber was ready for the staining to be carried out. We headed off to the sawmill near Osterley on a fine and warm day, where the timber had been placed in stacks ready for the work. We worked in three teams and once a stack was stained Tad, the sawmill owner, replaced them with another lot.
It takes longer and requires more stain for the first coat, but we managed to finish all planks before lunch. In the afternoon session we comfortably disposed of the second coat in a little over 1 ½ hours

One of the preferences of the Tasmanian Community Fund when giving funds is for the supply of goods and services to be from Tasmanian businesses where possible.  We used the local supplier The Tasmanian Paint Shop for the stain and the sawmill Timber Growers Direct for the timber.

Trevor from Mount Field, who has many years of experience with using timber in park projects, was very impressed with the quality of the timber.  It is extensively dried before cutting up and as the plantation is in a relatively slow growing area the timber is practically knot free.  Allowing the timber to dry out, reduces the number of helicopter flights required to fly the timber into the site and a reduction in knots and the slow growth of the timber means that the timber is stronger, has less potential to warp and deteriorate over time.

The timber stained is for the construction of a boardwalk over a badly damaged section of Windy Moor, which is crossed by walkers on their way to and from Mount Field East. A distance of 910 metres will be hardened in this manner.
This project has been made possible by a grant from the Tasmanian Community Fund as the primary funding source. The Friends of Mount Field also received vital contributions enabling the work to proceed from (listed alphabetically) the Australian Plants Society, Hobart Walking Club, Gregory Kidd, NRM South, Pandani Bushwalking Club, Parks & Wildlife Service, Wildcare Inc. and Phyl and Bob Wyatt
For over 15 years the Friends of Mount Field have worked on maintaining and repairing the walking tracks that form part of the Mount Field East Circuit Walk, together with the side tracks to Seagers Lookout, Beatties Tarn and to Lake Webster via Kangaroo Moor.  Repairing and rehabilitating the part over Windy Moor has always been an ambition of the group as well as a high priority for the national parks managers, but until the Tasmanian Community Fund provided a substantial grant it was not possible. 

Some data worth including.
The boardwalk is to extend for 912 metres and is double planking. Each plank is 6 metres long, 200mm wide and 50mm deep and that totals 304 individual boards.  This took 111 litres of stain.  Only the top surface was stained and was done using rollers.
The specifications for the stain indicated coverage of 12 sq m per L, but with raw planking timber that soaks the first coat quickly, that cannot be achieved.  This was discovered on a recent project, but that was after the budget for the Windy Moor grant had already been submitted.  As the cost of stain is substantial, a successful request was made to Wildcare to fund the shortfall.
Adrian made some calculations which are valuable to have reference
MINUTES per board first coat 3.42
MINUTES per board second coat 2.42
 MINUTES per board two coats 5.84

COVERAGE first coat sq m per L  5.40
COVERAGE second coat sq m per L  8.29
COVERAGE average sq m per L per coat 6.54
