fabricate remaining parts peices , fit and tack in position. Note formed strap in 3 picture - seems main pivot to tube should be welded first then dressed - after this is completed the strap will be welded per plans. DCN for 1x1x .125 wall square tube has been complied with.
Just some notes the althread and misc bolts are simply part of the jig to hold everything in place and will be cut away after welding is complete and the part has been heated for stress relief . I have information from the EAA tech section that stress relief is not necessary with the TIG method but it cant hurt either .
