    Default EFWD Build

    OK, I am going to post questions earlier in hopes of not having to fret over trial and error work. I am working on centering the flapperon in the jig and before I use an entire tree remaking the jig until I get it right I am wondering if someone might have a trick to drilling the spar hole so that when the flapperon is placed inside the block, the leading edge and trailing edges line up. I have drilled the spar hole right in the center of the seam but as you can see it does not align the edges correctly.

    You mentioned that the spar hole is centered, but your photo shows off center. May be the camera angle, but it still looks off center. The difference in the photos appear to be the same amount that your alignment is off.

    Well, upon looking at it while removed from the spar, it appears your right. I placed the drill press bit in the crease but I think I may have not tightened down the deck of the press. I think it may have wandered. Thanks for your comment.

    Personally I would forget drilling the spar hole just right. Drill it quite a bit oversize to make plenty of clearance for the spar. Then just butt your clamped blocks to the end of the flaperon, carefully lining up the leading and trailing edges with the split in the blocks. Then just trace around the flaperon end with a marker and your ready to bandsaw out the profile. Use the outboard end of the flaperon and you don't even need to drill a clearance hole for the spar.

    Eddie,

    I'm far enough behind you in the build that I have no clue what this step involves. But I want to thank you for posting the question and others for answering. It's added to my list of threads to re-read and will obviously be helpful when I reach this stage.

    Any guidance is appreciated. Otherwise I have to call John on Tuesday.
    I am installing the wingtips. I have trimmed only 1/4 inch off the fiberglass along the scribe line as instructed by the manual. Has anyone installed these lights and how have you maintained adequate room. the way I see it, if I dont trim the leading edge spar back a bit then this light is not going to fit. As you can see I need this wing tip to push in about 1/2 inch more for it to but up against the capstrip. It seems I am needing to trim 1/2 inch off the spar. Thought I was pose the questions before I get my self in a corner.

    I cut the spar flush which gave enough room to install the light. I also made a frame to go around the light out of aluminum for better support. If you'd like can see it in more detail at mykitlog.com, search under Kitfox and Brett Holland

    Ok, since I ran across the Oratex product at Oshkosh I have requested a price quote from the company in Alaska. I first got a "rough" quote as I was told he didn't have the data on the Kitfox SS7 to more accurately price it out. I believe there have been individuals here who have purchased Oratex for the SS7 which I would think the data would have been retained on file. After I gave him the data he required on the plan views provided by the builders manual I have yet to get any information. I have sent an email with a reminder that I am still waiting for the detailed price quote and as of yet, crickets from the other end. Can anyone speak to their experience with customer service from Oratex. This is a bit concerning to me and Im somewhat uneasy with ordering this stuff at all as a result. It seems I can reach them by telephone easy enough but to have emails ignored may just be the start.
