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.

Morning, Ben...

Well, being biased, and having introduced this group to the Pettit/West Marine paints several years ago, all I can say is to give it a try...from my experience, as well as others, I think you'll like it!

A couple of others here used it to patch their planes when they did some repairs on them, and I haven't heard of any complaints.  However, I'm glad you said "somewhat match".  Remember that there is NO "standard bright white paint" for our planes, and every builder could use any brand he wanted.  Also, with age, any color will change somewhat, so you may not find an exact match, even if you use the same paint from the same container that it was originally painted with. 

But for relatively low cost, ease of application (using a roller), and brilliant glossy finish, I don't think that the Pettit/West Marine white can be beat.

Hello,
   I am trying to some what match the long ez standard bright white paint.  I have heard the pettit epoxy paint from west marine is pretty good...  Also, aircraft spruce is right around the corner so that is an option.  I am only painting the cowlings so it doesn't need to be very much paint.

Any thoughts?

Remi,

               Don’t even look back.  Go ahead with your skin layup.  There are some dry strands in the S glass, but don’t lose any sleep.

Please evaluate the dry areas of my wing spar cap layup. Shall I
proceed with the top skin layup?

Used MGS 285 with slow hardener, working temp mid 70s. Epoxy samples
passed scratch test. Spar tape used on bottom spar cap without any
problem -- about a year ago.

Re: COZY: Scrap the wing! Maybe BS!

Chris Byrne <jack.byrne@...>
 

Remi.

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.

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...

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 .

Rowan

I agree whole heartedly with Rowan.  Those are not acceptable layups.  Time to get out the grinder and

I'm pretty much down to a choice between the Taiwan-made 6104T, and what appears-to-be U.S. made Duff-Norton LT100-1-100.

Does anyone here have experience with Duff-Norton electro-mechanical linear actuators?

In general, the modern batteries, Lithium Phospate, do not respond well to a full discharge. Randall Fishman told me that if discharged to perhaps 30%, I might expect to get 1000 re-charges out of a battery pack, but if fully discharged on a regular basis, maybe only 300 re-charges.

I don't know of any battery type that does well in cold temperatures.

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.

Harvey is a good friend of mine and also made the electronic gauges I have in my COZY.  They read out in light bars rather than needles.  Ive had them  for 25 years now.  His shop is only 10 miles away and I highly recommend him.
