It doesn't cost anything (except time) to download and read the Open-EZ plans. The same goes for Ary Glantz's build log, here: http://www.aryjglantz.com/
Hey, thanks zolo, I thought Ary's website was dead. Maybe he had slow period at one time? Haven't seen it in several years. Perhaps one of the best build sites ever...

Cameron, I'm am truly sorry to hear that you lost one of your children. I've had the same and it never leaves you. Keep working and someday you'll get there, even if it's when the children are all grown :)

Well dang. That was good stuff for gluing up wood. I've used it to make wooden beams.

"Weldwood Plastic Resin glue"
Kent, are you sure? Maybe it's a different one?

Been for sale for a couple years and posted May 6 at $40K. No pics in the ad. Seller only wants to speak to "serious buyers". Maybe that's why he isn't selling. Can you imagine a used car lot with a sign "serious buyers only"? Jeesh.
It's not just aircraft sellers. A lot of ignorant people trying to sell something with little description and no pictures. It always amazes me.

SPARKPLUGS - I have not had a spark plug blow out but others have. A recent post on the Cozy list described an 18 mm adapter + 14 mm auto plug blew out of an IO-360--top one in pic1. His other adapter had cracked threads. I have used adapters with 14mm plugs as well as 18mm Autolite 386 plugs and 18mm Bosch M8ACO. Never had any problem with any of them but the adapters are a bit fiddly and I can't tell any performance difference between the 14mm and the 18mm. Using 386s at the moment. It seems that the 18mm was mostly developed for tractors. They are cheap enough that you can toss them every year or so.
I looked at some scrap cylinders I have as well as a new Superior Millenium and they all have very few threads in the sparkplug holes--about 5 threads (pic 2). An 18mm Autolite 386 has a 1/2" reach and it only has about 5 threads too so I suppose it is a good match (pic 3). An aircraft plug has about 6 threads with the copper washer used (pic 4, an REM38, electrode removed).
None of them stick very far into the cylinder (pic 5). You can buy Autolite 388s with a 9/16" reach but they do not seem necessary.
Lightspeed says torque the insert to 25 ft-lbs and the 14mm plugs to 15 ftl-bs, Lycoming torques 18mm aircraft plugs to 35 ft-lbs. I gather some brass inserts are of higher quality than others. Don't know which, though.
With inserts or 18mm A/C plugs I keep a string of copper washers handy and anneal them after a couple uses. Get them cherry-red and allow them to air cool which softens them. Somewhere I read to use copper anti-seize on sparkplugs and don't get the anti-seize on the business-end of the plug.
I do not know if heat-range is very critical in these old low RPM, low compression engines. If your plugs are fouling it can be lead, oil, or carbon. Lead must be blasted off with a machine, carbon can be removed by a lean runup and running lean when able. Oil, you can't do much about except refresh your cylinders.
Reasons why a plug might blow out? I'm guessing old, beat-up inserts, improper torque or maybe an old copper washer which does not seal as well
I have always used Champion spark plug anti seize for aircraft on my race car spark plugs with aluminum heads, and also on my street cars. I've never had a problem. My bottle of anti seize must be 25 years old now...

I'm not sure of the site costs and so on, but there is a store link at the top of the page, it has some resources you can buy, or just fund a coffee in appreciation!
I never even noticed. Just bought 5 cups Hope it helps.
Thanks for the tip Cameron.

Gotcha. I always assume that vacuum lines will get gasoline vapor at some point, which will eventually return to a liquid state IMO. On cars anyway. Same thing should be true of aviation engines I *think*.
That is pretty small at 0.079 ID. The 3/16 is 0.111 and the 1/4 is 0.15, which I'm sure you already know. I like the nylaflow hose for many things. Tough and durable, and holds its shape very well. I use a lot of the 3/8's in industrial applications.
-
It's also the color of your lines. Standard nylaflow is not fuel rated. Nylaflow LM is fuel rated. Not sure if that is an issue...
Are your lines nylaflow? Looks like it might be something else.

The rule of thumb we have used in industrial electronics, ground the shield on the source end for DC signals, and both ends for AC. When you have DC that is pulsed at higher frequency (encoders for example) the "guidelines" get murky. For high frequency encoders we have done it both ways, with good results either way.
The why is complex...
-
Good point on the exit needing to be larger than the entrance due to the expansion of the heated air. On industrial ovens we bring the fresh room temperature air in an opening 1/3 to 1/2 the size of the exhaust. The water vapor in our application expands quite a bit as well.

Whole thread can be seen on the Canard-Aviators Google.io group....
I really liked this comment "Get the right nut, or re-cut a perfectly good part? "
The "right nut"? How does one choose a "right nut" for a defectively threaded part?
-
That threading wouldn't be acceptable for non-aircraft related uses.
Both parts are junk.

Looking at the pics from the Cozy 3 above, man that is fitting heaven on the fuel line. The builder must be a wholesale supplier of fittings...

Do you have to pay by the vowel to advertise in Barnstormers?
Kent, your abbreviations escape me.
The abbreviations are from the add, not from Kent.

Now that's funny...
I see the downloads Jon.

Beautiful EZ
-
Good luck with the search. If you haven't already, check out the "for sale or free" thread. Lots of posts with for sale planes there.
-
Good reminder on water and debris contamination.

"I'm buying this, pending the details. I'll do all the reading I can..."
Wow! Congratulations, looks like a nice EZ. You are in the right place...

Looks like the McMaster version has anti rotation flats...

Barnstormers VariViggen pics are up now.

Thanks Marc.
I haven't seen or haven't noticed the firesleeve before. Gives it a different look.

Sorry, the oil cooler hose/tubing. It doesn't look like the typical stuff I'm used to seeing.

A lot more done since I last looked at his site. But it has been several years I think. It was too depressing knowing I was just getting too old to think about building one...
OTOH, I still enjoy reading and learning and especially seeing pictures of nice work.
