I didn't get out to site on Saturday or Sunday.
It was absolutely miserable weather with drizzle and strong winds.
Also I was fighting a fever for several days.
Eventually I made it out on Monday (I'm having a week off work).
The day was overcast with just a few short showers so quite a good day for working.
I wanted to complete the detailed welding of the 13 m beam on to the columns.
In order to align the columns correctly I needed a clear view down the procession.
Towards this end I started to move the hoist out of the line of sight.
Once again the small wheels were bogged in the sand so I needed to use a lever to move the hoist along.
I had the heavy timber platform at the top of the hoist to facilitate the draping of a tarpaulin.
I did not realise how top heavy the hoist was and toppled it over.
It sheared the next column off at its base and whacked the column after that.
For a second or so I was afraid that the whole beam and column structure was going to fall down.
This was followed by a lot of swearing.
The hoist was too top heavy to lift back up so I needed to use piers of bricks and levers so that I could jack it up enough to remove the tarpaulin and the top platform and see what the damage was.
What I found was that the column had not sheared off at its main weld to the screw pylon but at a 20 mm extension that had been welded on. One side out of the four remained intact.
It was lucky that the column sheared off - otherwise I would have ended up with a bent piece of steel and this would have been a major undertaking to replace and make good.
After clearing away the hoist and performing some cleanup grinding I was able to return the column to its correct position.
I rewelded the extension with a very thick, strong weld.
All up maybe this mistake cost me another 45 minutes.
Ross came over to see how I was going. He very kindly helped me load the hoist on to the back of my utility using his bobcat.
This was an absolute life saver for me - on my own, this sort of task takes me an hour and a half of hard labour.
He has helped me out with quite a few things recently - I must buy him a bottle of "Wild Turkey" as a small token of my appreciation.
I spent the next half of the day setting each of the columns to its vertical position and tack welding.
As I worked I also removed the brick piers and tripod that I used last week.
Next I revisited each column to perform the detailed welding.
Finally a third pass where I cleaned up every weld with a grinder and applied primer.
I still need to cut the beam to exact length but I think this is an early morning, clear headed job.
I gave myself a rest on Tuesday and started again on Wednesday.
I was up at 5.00 am and headed back home at 9.00 pm.
The forecast was for a few possible early showers. The prospect of relatively dry weather was what I was hoping for as I needed to remove the roof edge at the back.
Initially I rerigged the existing tarpaulins and during the day added a third one. This was in case it rained on Thursday or Friday while the roof space was exposed.
I scraped and steel brushed the upper surface of the 150 PFC attached to the core of the house on the back wall.
Then a light application of rust converter (the beam was already enamelled but had a few rust spots breaking through).
I gave it just an hour, wiped off the rust converter with a damp cloth and then gave it a new coat of enamel (Mission Brown Kill Rust).
When the enamel has hardened by Saturday, I will attach the flashing (same as the front of the house) and then I can finally start installing the back purlins.
The rest of the day went on painting, painting, painting.
I have just painted each cleat of the newly installed beams.
I will try to paint the areas in between soon but at least nothing will be stopping me installing the purlins now.
