The first part of the work is finished: Lamination. Now comes the second part, tapering the booms ang gluing them together

 

Tapering in height :First step is signing the cut line (look how much wood you have to cut!!)

 

What we found to be the best solution at the problem:with the help of a professional Woodworker we tapered in dimension the forward and aft faces of the spar (should better say the two booms because  We gave the didhiedral to the booms first).He found out thisvery good method: with a portable saw he cut the right angle using a wood straight ruler as a guide, and after 5 hours of precision sawing we had in the table two booms that started looking like a spar, weighting nearly the half .We had then to taper the inner face of both the booms , and with the help of horses we did it using a power plane.

 

Preparation for the final gluing up: these are the big wood blocks in the center part of the spar.
