The manual talks about a mark on the inboard end of the spar to use for in-and-out location of the spar. My spars do not appear to have any marks at all in the area discussed in the manual. I do not see any other easy way to accurately locate the spar in an inboard-outboard direction. I am also trying to locate the spars in a fore-aft direction. The instructions specify measurements from the leading edge of the wing to the face of the spar at one BL station, and from the front spar face to rear spar face at several other BL stations. When I try and locate the rear spar using these dimensions, the spar is almost completely hanging off the core outboard of the jog in the spar. This does not seem right to me. Further confusing me is an instruction that I should essentially ignore the dimensions and slide the spar in a fore-aft direction until a 3/8 inch gap is left between the spar and upper jig board to provide clearance for the upper wing skin and core. To attain this gap, it looks like I need to move the spar forward about 1 inch from the supplied dimensions. This has the benefit of getting most of the spar back onto the cored skin, but then I am concerned about being so far from the specified measurements. Any suggestions/experience would be appreciated. 1) Any suggestion on how to locate the spars inboard/outboard? 2) Has the rear spar been off the core this much on other kits? 3) Are the supplied dimensions incorrect? 4) Any better means of locating the rear face of the spar than those given in the manual?
