The garage under construction

Here is a small stack of timber that has had its rotten ends sawn off:  

It is pitch pine - almost unobtainable nowadays.

And here is the back wall taking shape.   The timbers are massive, and once the rotten ends have been removed, they are good as new.  

Below is the first completed roof truss, or A frame, out of five.

Here is the second truss during renovation.   The new wood will become the main tie beam and the original, partly rotten tie beam to the right of the picture will be sawn off, making a slightly smaller but much more rigid truss.   Sandwiched between the new wood and the old are galvanised joint fixers.   When compressed as the bolts are tightened they make an incredibly rigid joint.
