Added last lamination of the spar sheeting.
Cut out and match drilled the doublers for the landing gear mounts and bushings. The landing gear retract bushings that run through the spar are just over 2" diameter. Previously, I used a 2" forstner bit to make those holes through the spar and then cleaned them them up with a sanding drum chucked into my drill. The doubler on the front side of the spar requires a hole that is 2-1/2" in diameter to allow for the shoulders that are on the bushing plates. Fortunately I had a 2-1/2" forstner drill bit from a previous project to cut the larger holes. The edges of the holes then needed to be beveled to provide clearance for the weld fillet on the bushing plates. That worked out nicely but I'm a little disappointed in the bolt holes in the doublers. I should have clamped some scrap wood to the backside of the doubler while I drilled through to prevent the splintering you see in the picture. Fortunately it's not critical and those bolt holes will be covered by the bushing plates so no one will ever see them once it get's assembled.
