2016-Jun-18 - Wooroloo - Loft Floor Joists #45
On Saturday we were having some long overdue repairs to the ceiling of our residence so I stayed home that day in case there were any issues.

On Sunday I arrived out on site after 9.00 am and made a very slow start.

The aim of today was to tidy up the heights of a few purlins near the transistion between the stud frame and the steel structure.

I needed to elongate the bolting holes on a few purlins so that I could move them up a few millitmetres.

To this end I had purchased a welding burr and pneumatic drive for it.

Although it took a little bit of getting used to - this worked quite well. It was small and handy and allowed me to work on a purlin without completely removing it.

However, by the end of the day the drive had lost its power and could be easily stalled even when the air compressor was fully pumped up.

I ended up having to completely remove a few purlins and work on them on a bench using a conventional drill.

These only run at a fraction of the speed required so it was a slow process.

Consequently I was not finished by the end of the day.

Looks like the last step of installing the floor joists is going to be the most time consuming.

I unloaded my compressor, took it in to my workshop, pumped it up and connected it up with a single length of high pressure line.

Now it gave me about 30 seconds of grinding time - which is about what I had been told when I bought the device.

So it looks ok - I will just have to position the compressor close to my work.
