You can say all that again and much more besides!  The joy of 
restoration and rebuilding is working alongside the dead men and 
finding out how they were working and striving towards their goal.

Certainly not!  This is a project that ought to have been completed 
18 months ago but a major operation I had early last year followed by 
a whole year with most of my stock in a barn while I waited for the 
new workshop to be completed has rather altered my schedules and 
priorities.  The spring should see progress and I hope to report on 
some of it then.
