    Open-Ez wing spar-cap thickness (thicker than a Long?)

    Void, Could it be that you are using dimensions for the added spar cap layers, for example: .450" for the top CS root from the Long EZ plans? Then comparing this to the measurement from page A11 spar cap template? These templates are meant to define total material to be removed from the foam prior to glassing outside of CS spar. I measured (digitally) the open ez top CS spar root at .49" depth. The original shear web was 3 plies of BID which adds about .010" per ply (add .030") In the end, .030" shear web + 0.450 spar cap nets 0.48" total depth. I for one am not going to loose sleep over ten thousandths thickness, even if it is in my spar cap. If I'm way off on this folks, let me know. Jay

    Doesn't that just mean I need a bigger hanger?

    Sales I've seen

    I did the engineering for that chute install, and Burrall did the install. Interesting that it's for sale just a few years later.

    Sales I've seen

    Been doing this thread so long that airplanes are coming up for the second time. This one on Facebook today N1361S, a 1997 build by Larry Sligar (plans #74) which I first talked about here http://forum.canardaviation.com/showpost.php?p=71237&postcount=70 It was nicely built but a hangar queen for a good many years. A couple of guys bought it from the widow and the engine threw a rod after they flew it a while--lesson there about engines that sit. I suppose all that is in the past now but it'd be interesting to inspect the engine logs. Ballistic parachute!

    Propeller choices

    All, I’m interested in which propellers are being used for the COZY IV and what performance numbers you are getting. Best rate of climb speed and rate at minimum weight. Max WOT speed both in run up and at altitude. Thanks a bunch! Joe Turecamo Cozy MK IV—building the strakes View the full article

    Kent's Long-EZ project

    Geez, after buying a $200 Vividia borescope to look at my valves (see Aug 24 in this thread), I was just reading about this one (pic) for $29. The previous problem with these cheapies was that they were not flexible enough to stick them in the plug hole and bend them back to look at valves. A Vans owner says this one can do it. It could probably be glued to a piece of bendable wire and inserted into the cylinder. Why do this? Regular Lycomings have notoriously-poor valve stem lubrication. https://web.archive.org/web/20050217090118/http://www.prime-mover.org:80/engines/Marvel/tbo3.html So the valve stems wear and the rocker arm pushes the valve head off center. Heat does not transfer evenly around the valve head to the valve seat, the valve head gets heat-stressed and a piece breaks off, or the head breaks off. What you don't want to see is a half-moon discoloration (pic). There is a really bad case in this video https://youtu.be/x6OyfoV1Z2I

    Fuel pump vent

    Thanks for all the answers what to do with the fuel pump vent pipe. Taking it apart for the new fittings I found this genius idea. Looks like a home made check valve made from a rivet. How come Lycoming didn’t do that? ;-p View the full article

    West 105 is really easy to sand

    Yep and if you switch to West's plastic filler it will be even easier. The only real data point I have for that opinion is that strakes filled with micro glass balloons seem to be more resistant to dents and dings from the car-keys-in-the-back-pocket. I use micro balloons there and also on the wing and canard leading edges.

    West 105 is really easy to sand

    I've made more dumb mistakes with filling than probably half a dozen of any of you! I found it really hard to sand when I first started out on some educational pieces. It took me quite a long time to discover that I was using a micro-BLEND, not just micro. Blended with colloidal silica, the stuff that makes it cure really HARD! Then later when I switched to my 'production' epoxy, the sanding was pretty hard too... because I am using a TOUGHENED resin! Once I switched to micro and a non-toughened resin for filling, it got a LOT easier!

    West 105 is really easy to sand

    Everytime I rush things, it is a mistake. Get the surface filled, leveled with the aluminum bar and all the sanding scratches sanded out and defects filled or removed. Then spray the thin rattle-can primer and sand it all off; it will reveal additional scratches and defects. When those are fixed you are ready to fill pinholes (yes, they are still lurking there) with the "Cory Bird" method of straight epoxy wipes. Wet-sand that smooth and you're about ready for a primer-surfacer.

    West 105 is really easy to sand

    I feel like I have a chance at dealing with the Finishing process when I get to it (which I've been told is 33% of the entire build). West is your friend and there are a lot of good guides out there, such as this one:

    West 105 is really easy to sand

    I'm actually using West 105 Resin with the 209 Extra Slow hardener. The properties for 209 are slightly lower than the 205 Fast hardener, but the window before cure is MUCH longer. I like going to bed sometimes. 😉 Ah, I just learned about the line of West Filler products. Cool, I'll have to get some and try them out! Thanks for the tips -- my next question coming in here today was going to be about when/how to transition from epoxy/filler to primer.
  20. Hello Folks, I'm working on the Dynon EMS 37 pin main sensor harness connection and the fuel flow red cube. I found that two harness wires (which supplied by Dynon) have been switched between themselves (just a matter of wires color) Can anyone shed light on this and how I connect the fuel View the full article

    Exhaust pipe baffle

    Have a question for the group. The exhaust pipe baffles they say to make make with 6061 T3 aluminum .125 thickness. I cannot seem to find that at Aircraft Spruce or Wicks. So the question is could 6061 .125 T4 be use there instead? Looking forward to meeting up with some of you at Rough River. View the full article

    Re-do... part 2

    RAW (Keith), This is unknown at this time - the first thing I need to assess is what I got and what is good... I am still waiting for the shipper to make arrangements. They put a couple things together in a trip to make it more affordable to the customer. I have been reading the HECK out of options - It may turn into a Vari-Long (wings and spar) - depending on what the analysis of the rest of the airframe is. Stay tuned! (I hope it is not going to be much longer!!!)

    Safe harbour

    Just wanted to throw out an offer of hanger space if someone needs to get out of the path of Florence. I've had 2 Cozies in the Hanger before, and could re-arrange and make it happen again. In Athens GA (KAHN). --Craig (_ |-------==(_)==--------| o/ | \o View the full article

    Open-Ez wing spar-cap thickness (thicker than a Long?)

    The cap or the trough sounds like the chicken or the egg 😏 Isn't Everyone is correct? Mark says its the depth of the trough and John says its the cap thickness but I would think your plans SHOULD make it obvious that they are the same. Why don't you call Steve James at Eureka 702-416-8729 and ask him what depth he cuts the spar trough. (obviously its tapered)
