  1. Forget all that.

    Break out your Open-EZ templates, or better*, an original set of Long-EZ templates; refer to page A5, which as you know shows the details of the gear brackets and surrounding fuselage structure. Assuming your fus is, or will be, built to plans, craft your gear attach brackets to fit/match you’re A5 drawings. Couple of important things to check here before you break out the hacksaw and files:

    1. On the Open-EZ templates, at least for the purposes of this thread, forget about using the added “scale dimensions” along the bottom and side of the page to check for scale accuracy, rather, CHECK THE SCALE ACCUARCY OF TEMPLATE PAGE A5 BY CHECKING THE MEASUREMANTS BETWEEN THE F.S. AND W.L. NUMBERS, AND CHECKING THE MEASUREMANTS OF THE OTHER COMPONET POSITION DEMNSIONS INDICATED. On my printed Open-Ez templates, the plan W.L. and F.S. and EVERY OTHER dimension checked “DEAD-NUTS, PERFECT, RIGHT-ON-THE-MONEY, doesn’t get any better than that!” While the so-called added scale dimensions are off by ¼” and 1/8” respectively. This means if your templates are to scale, you can lay your 2x2 extrusion in place on the page and its width will be EXACTLY as drawn. Mine did.

    2. Figure out where your AN6-80A holes will be drilled on the brackets (remember their centers are 0.4” higher than plans per the CPs )

    3. Use the “full scale"drawings in chapter 9 as “shape” guide lines only, with the 0.4” move in the AN6-80A hole placement and the material equidistance called for around the holes, the finished bracket won’t look exactly like the chapter 9 drawing anyway. You can use the A5 template to figure the original W.L height of your AN6-80A bolt. The top or your upper longeron is W.L. 23. Again remember, the CP’s call for those AN6 holes to move up 0.4”. Confirm this finished elevation using W.L. 23. as a bench march. And remember, don’t run your 15 ply bid pads up any higher than W.L. 12.35 (look for that little note on A5) If you fabricate and install your brackets per plan and CP, the W.L.12.35 caution is a non-issue for the brackets, but still applies to the 15-ply bid pads at the aft or larger bracket though.

     

    Hope this helps

    * Note for Jon: "Better", only because the user didn’t have to drive to Kinko’s and put out 40 bucks to print them out. :cool:

  2. make sure there the recent drawings current to 2006 if you can

    and make sure all the pages are present especially the spar layup and construction ones as you will more than certainly want those

    Colin, Thanks for the tips. TMann said there were 99 pages: I'll count 4 sets of 20 and a 19. Not sure if these are current thru 2006, but I'm sure they will prove more than sufficient for my purposes.

  3. . . .

    You start with a good female mold. After waxing it or otherwise treating it so that the epoxy will not stick, you spray the mold with epoxy primer. When the primer is dryish to the touch, you lay your glass on it and squeegee and squeegee and squeegee the epoxy into the weave (s). When all is saturated, you take, I believe it is called, . . . "

    A SMOKE BREAK :cool:

    ". . . Of course the quality of the mold will determine the quality of the part.

    Like a good cheese, it depends on the mold:p"

    For the guys,

    this could also be interpreted as solid Standard Operating Procedures

    on Valentines Day! :D

    It's hard to part with that much green but it's a great value.

    I paid more and do not regret it a bit.

    Thanks TMann, that's what I was thinking too, the impulse to tear my pocket open and whip out my wallet was strong when he told me he was considering a sale but resisted till I could run it by you guys first. I'll snatch them up tomorrow night.

  5. I ran into a someone with Berkut plans, just the drawings, expressed a willingness to part with them for $5-600: fair, good deal, dirt cheap, what a rip! Run! ??

    Anyone have a current opinion?

  6. Ahh, don't be sad, be happy :rolleyes: I'm sure you're in very good company with this one: From what I could gleam from the pictures posted on your blog: First, I think the work looks good, really good; Second, I think both the 15-ply pads and the bracket are relatively EZ to fix at this stage (cut-sand-go out for lunch). While you are in the midst of that little task, all you have to do to make yourself feel better, is think about having to do the same thing, only after :irked: the spar is floxxed in!

     

    A few more things come to mind here: IF your aft MLG brackets are fabricated to size per-plans, and the attach bolt hole locations are drilled per-plans, but, the AN6-80As were drilled at the PC call out of "up 0.04" as called for in CP??, and assemblies currently check to be installed up past W.L. 12.35, that could mean: The brackets are installed higher on the fus than plan spec'd, which means the lower attach bolts punch through the lower longeron doubler High and have less spruce-meat over them; the AN6-80A's are currently higher on the fus than they should be, which could mean (if all else to follow is built per plan) your ramp-AOA will end up higher, and your prop-arch will swing closer to the ground.

     

    This is what I'd consider doing in lieu of ripping it all out and starting over: - If the AN6-80A ARE currently at the W.L. level they should be considering the PC 0.04" change to the plan, and the lower bolts ARE drilled through High on the lower longeron. Carefully channel out the 15-ply bid pad under the bracket enough to allow the engine mount extrusion placement (WL 12.35 or lower) leaving the top of bracket unaltered (except as needed to allow extrusion bolts) to overhang the extrusion. Maybe also consider flox-packing the overhangs after the extrusions are installed. As far as the lower bracket attach bolts: If they are drilled "up" from longeron center and are lean of spruce, (cause of structural concern?) channel out the eurethane equal to the size of an additional spruce incert to work as a new doubler (trippler?) flox it it in, use gravity and leverage as your clamp.

    - If the AN6-80As ARENOT currently at the W.L. they should be considering the PC 0.04" change to plan: All of the above; consult our structural and or experienced builder/fliers gurus, make adjustments and any buildups needed when you fab to install your main gear bow.

     

    In any case, don't let this stall your progress, press on, consider dealing with it when you have lag time. Just as long as its before the spar install. Hope this helps. Keep up the good work.

    Martin, check the W.L. height of your 15-ply bid pads and the top of your aft main gear attach brackets, if either or both are above WL 12.35, you may have a Posted Image moment coming when you try to install the engine mount extrusions. If you’re using the Open-EZ templates, check A5, just aft of the aft-MGA bracket (near the top), there is a small penciled-in CP note addressing this. If you need to make any adjustments, pre-spar installation is the time to do it.

  8. Drew,

    I always find it amuzing when people start nit-picking anbout 10 minutes here and 30 there. What is the funniest part is that they usually have a project that has seen as much attention as they have spent being critical of the 'worker bees' !

     

    The project killer isn't mods, template routing, vacuum bagging (and on and on.) The project killer is avoidance. A day goes by ....... then it's a week ........ then a month.

     

    You're working on your project (more than others) so press on and enjoy!

     

    -----------------------------------------------------------------------

    Yeah!

    What Tmann said!

    Press-on Drew, any time spent defending being good at being productive, is time wasted, time that could better be spent slinging goo and kicking glass.

    Looking forward to your next installment.

  9. Ahhhh, with all of the above taken into consideration and noted (point for point), I’ll still say: Nice job, Drew! VERY NICE JOB!

    Everyone has their own way of doing whatever it is “they” do. Based on content and my own perceived subtext in your video, my best estimate is your Cosy will roll-out looking more like it was born of a precision factory, not like one that came out of a blender between margarita batches. I also predict: For project hours actually worked (not necessarily elapsed calendar days start to finish), and in spite of the attention to detail, you will probably end up with a record short time build. Call it a hunch. Keep up the good work and keep doing the Drew Show Videos. Ya Nevva know, you may just bump one of those silly a** reality shows right out of a cable slot and help ignite a new firestorm of interest in Canards.

     

    Well Done!

  10. . . . My guess is that by the time you do that, and pay for all that, you're not that far off from what I'm asking. But, that's MY opinion!:)

    If you catch Matt (over at TERF) in a good mood, you can do "ALL THAT" for under 2 bills. But that's just my opinion*! :)

  11. Usually the last words you hear before a guy unbuilds his kit is:

    "Hey guys, watch this"

     

    :D CHrissi

    Yeah! Followed by the sound of a chairsaw firing up! :bad:

     

    I have a feeling Tony's new bird is going to turn out much better than if the original builder had done a fine job from the outset and nothing needed to be fixed. He probably would have kept it and Tony would still be looking. I think at some point down the road all the crappy prelim work that was done will prove to be a silver lining in the bigger picture. I'd cut the poor guy some slack from here and focus more on what's right about all the work its going to take to get this beast up and boring holes. This is an exciting project to watch, I'm looking forward to seeing it completed. Need to back read this thread now, if it hasn't been brought up already, what's the disposition of Tony's original Long-EZ going to be?

    Good morning everyone! :cool:

  12. I'm going to the aircraft spruce open house in Atlanta Saturday May 19th 2007 and plan to place my order for the first several chapters of material.:D

    Okay Ken,

    Got an update to this drama? It's been 3 months since your last I'm gunna, lets have it!:irked:

  13. Excellent job on the foam cores!

    Good value excellent quality.

    Thank you for cutting them before you left.

    Here's a great example of ingenuity filling a niche.

    My wife and I thank you for your family's sacrifice

    Fly safe and tailwinds home!

    John,

    You probably don’t know how close you came to losing those cores to me. :bad: The truck was gassed-up Sunday night and ready to deploy complete with an alternate driver. Was just waiting for the call. Still, I’m very happy that things worked out for you. Keep us posted here under this thread how everything checks-out with the cores and how you think your build process was improved based on their use. I’m not quite ready for the wings yet, but I will be long before Steve returns. You’re a lucky guy my friend, now go out and buy a lotto ticket! :D
