Re: best paint?
David Fife
Hi all canardians. I am in the final stages of painting. Wings and fuselage complete. I am using base white. Matrix 2 stage with clear coat. Reason for base white is it is always the same white. All colors are based on this base color. I don,t expect matching issues. Pictures to follow in about 30 days. Long EZ N12LZ Dave Fife 3D Composite Aircraft Parts 248-505-8176

Re: COZY: Scrap the wing! Maybe BS!

That spar tape is often very hard to wet out even if its in good condition. You can soak it in epoxy and it will still not wet out in some areas. I frequently used a comb to separate the fibres within the strand to get the epoxy to migrate into the strand. Then straighten the fibres with the comb again once wet My spar caps took as long as 12 hours when working along, using very slow hardener and 80F temps. This was mainly due to the trouble I had getting the tape to wet out. (MGS) Just a thought, would a router get the tape out, you may need to keep it cool with water (that would keep the dust down as well) Dont electrocute yourself. Might be worth a try before you scrap the lot. Chris Byrne Sydney

Re: COZY: Scrap the wing! Maybe BS!
Remi Khu <cozymk4@...>
Thanks for all the input both on and off line.
Unless I am convince otherwise to continue with that wing, I will attempt to redo the spar cap or even scrap the wing entirely if necessary. It's simply not worth the risk, no matter how remote. I believe the spar tape got contaminated sitting in the basement for at least a year unprotected from the temp and humidity variances. That explains the inability to absorb the epoxy despite being flooded with the watery MGS 285. I should've stopped early into the layup but denial is very addictive. Lesson learned... Remi

From: row row Hi Remi, Its not looking good. Think of it this way. That cap could fail in a high 'g' manoeuvrings and your wife or children could be in the plane. Quite simply its not worth the risk. Have a reputation for being a safe builder, not a rush builder. A pain in the arse i know, but lock your self in a room, yell loudly, do something else on the planer and then get to work fixing this: the cap must go. Another observation is that the fibres seem very wavy in the picture. Structural integrity is achieved when all of the fibres are wetted out. Dry spots means weakness and unfortunately for you, the spar caps are the most important layup in the / any
wing. The correct technique is explained in the plans, but i cannot emphasizse how important it is to wet out the trough first, then lay the fibre in, remove the tacking thread and then work the resin through the fibre from the bottom to the top, working middle to outside. with a gloved hand and gentle but firm movements, including 'rubbing' the plies, you can achieve wetout. if its dry then stiple more resin into thearea and then work out the fibres straight again. Another trade secret is to cut all of the plies first, weigh them and then use the equivalent amount of resin in the layup. that will give you 50:50 resin to fibre content by weight, which is excellent for a hand playup. if you are a little dry and add more resin to achieve 55:45 then thats ok. A skilled person (someone who works with composites a LOT) will achieve 48:52 or even 40:60 resin to fibre
ratio. You are going to have to look at getting the angle grinder out and removing he cap down to the shear web plies . Regards, Rowan

Thank You!

Osh Canardians,
This was our 10th & 9th Oshkosh, 3rd Annual Spaghetti Dinner and 2nd
Osh with Red Flyer.
Thank you to all of those who were able to get to the dinner and meet up
with your fellow Canardians. The weather cooperated perfectly and provided us
with a great day to get together with 200 like minded friends.
Randi and I would also like to acknowledge and publicly thank our helpers
this year, Elizabeth Ferrell AKA Velocity Girrrl, she is our "door lady", Bob
Tilley, Elana & Doug Hurd, George & Vickey Rippeto, Nick Ugolini, Steve
Parkins and another gentleman with a hat on who did an huge amount of work and
he did not have a name tag, I am sorry I have a terrible memory and cannot
recall his name. And anyone else who helped, THANK YOU, we could not have put
this together without the team effort. We are planning on doing it again Oshkosh
1012.
I hope that those who wanted to hear Randi's strake presentation were able
to get by our booth and chat with her. I managed to put the binder together for
her days before the show and it seemed to help. We probably need to find a space
next year to get together and discuss building without the sun and
distractions.
Thank you as well to Jim Irwin and Desiree at Aircraft Spruce for providing
us the space and opportunity next to Burrall and his Cozy to meet with Cozy
builders, we hope builders and hopefully-to-be builders found this to be helpful
and informative.
