The hours are an accumulation from my last entry at the end of December. The wing upgrade has been slowed by a number of things (1) the weather, the low low temps have made the shop difficult to heat to an adequate temp to rivet materials., (2) Tools - not having the tools for solid riveting and needing to borrow everything, (3) a lot of drilling of rivet heads and rivet removal do not make for much to write about. It's just time consuming and takes lots of hours.
