This morning GAM deburred the rear spar whilst I assembled the jigs, deburred the tip rib & turned the diameter of the main spar jig bolts down in order not to damage the spar holes with a force fit. GAM returned home at lunch time, thankyou once again for your help. I mowed the lawn before a storm passed then when the weather had cleared up, I sprayed the rear spar parts & the tip rib with primer. Tomorrow I will prime the contact areas of the main spar prior to trial fitting the ribs.
