The second layer continues

Progress has been a bit slow of late, due to spending two weeks in Australia for work.  Currently working to complete the second layer.  I had the same fairing issues on the starboard side that I encountered on the port.

I made an interesting discovery.  For the last couple of months I have been getting very poor results from my brad gun.  What seems to be happening is the hammer is coming down the side of the nail, this generally results in a brad that is only set about 2/3rds the way in.  This hasn't really caused two many problems, just looks ugly.

So on the weekend I nailed a bunch of strips, and then went on to another job, and then came back to nailing some more.  In between I had unplugged my compressor.  As I was coming to the end of my glueing / nailing session, all of a sudden my brads started setting perfectly.

Turns out I have been using way to higher air pressure.  The compressor had bleed down to about 4 bar.  I did some experiments and through ply they work perfectly, if the hit sapalle then they tend to still sit quite proud, but the hammer hasn't gone down the side and munched them up.

I did experiment with pressure a while back, but I don' think I every went below about 5 bar during those experiments.

No photos, because you can't see a difference.

Just checked my schedule and I've slipped about 3 weeks already for the year.  Not helped by the aussie trip.
