OMG Michael, a slight warp you say, that is horrendous and full credit to you having a go at fixing it with the spares you have.
Not that it is going to make you feel any better but I did hear that we had the coldest night ever recorded for July, -29C in the snow fields, and we had -5C here in the big capital.
Also correction Andy, the finish date is Sunday, 1st September, so you have some time up your sleeve Michael.
