2008-Apr-20 - Wooroloo - Installing the large PFC beams
This took us two days - Ian Chalmers brought his excavator and initially tried the 'grab' fitting.

The first beam fitted was the 10m verandah across the back.I didn't give specific enough directions and the beam went on upside down - which conflicted with the radii I had ground to allow it to seat well in to the welded on landings.

However a session with a small angle grinder and some bashing with a 3lb hammer soon sorted this out.

In the meantime, Ian's excavator had broken down. Turned out to be a loose hydraulic fitting. The warrantee support was pretty good, a mechanic visited us way out in Wooroloo and had it working within 3 hours. I was a little relieved in a way as this gave me a chance to catch up on drilling holes and fitting bolts.

I had hired a magnetic drill, but this weighed 40 Kg and the solution appeared worse than the problem - that was a waste of $120.

Ross, next door, showed me the correct method to drill 12mm holes through the steel - this process was very slow - some holes were through 18mm of steel, with high tensile GR8.8 bolts fitted.

All other beams were installed using chain and spreader bar

A 12 m beam was fitted over the garage doors - the length required is 12.6m - so waiting for Ross to weld in the last 600mm.

The front beam is a sandwich construction - two PFC's around the bracket - one beam for the verandah, one for the house interior.

The drilling and fitting of bolts was a very time consuming operation - this took me another two weekends until every bolt was in place and all the clamps could be removed.
