Commenced solid riveting on wing spars. Almost completed one spar - found it difficult to set the rivets along the top of the spar doubler because of the bend at the top, so have ordered a 5.5" head which should be long enough to prevent the spring on the air gun from hitting the bent section when setting.
Happy with most of the rivets - had a couple that I had to drill out and re-set because of damage to the head caused by the gun slipping, but 99% worked fine.
Also cut the front upper strut fittings (7V2-5) and tie-down rings (6W9-1) from 0.125".
Learned a lot about setting solid rivets - hopefully the other spar will be problem-free!
