Mike B Posted May 29, 2019 Share Posted May 29, 2019 The CZ IV nose struts aren't currently available and won't be for, "some time". Can I use an L-EZ strut? I'm told I'll need to modify how the nose caster fits. Any information would be appreciated! Quote Link to comment Share on other sites More sharing options...

I'm told I'll need to modify how the nose caster fits. Any information would be appreciated! You got info from Aerocomposites. yes? Personally, I think I would build the rest of the nose and wait for a Cozy strut to become available. If the MKNG-6 is installed squarely in the NG boxes and operates in-plane with the aircraft centerline, it should be quick work to install the strut and wheel later. I believe the EZ strut is lighter and shaped a little differently at the top for the EZ NG-6. Jack Wilhelmson sells two versions of the NG-6--one EZ, one Cozy IV--which seems to confirm that. There is discussion in the Cozybuilder group archives about dimples in the lower casting to retain the casting, or drilling for a bolt. No opinion there. One thing for sure, the lower casting pivot should tilt slightly aft at the top when you're done on the wheel will be prone to shimmy.

I don't remember exactly what the difference is between the LE and COZY MKIV nose gear strut, but it's pretty minor. But Jack's NG-6A's aren't different in the way they attach to the strut - they're different in their overall width and how they fit between The NG-30's, which is different between the LE and COZY MKIV. And as someone who's built one of each, you should know that :-). Quote Marc J.

Mike B Posted June 28, 2019 Author Share Posted June 28, 2019 The news from Aerosport isn't good. I can't wait for many months for the possibility they might run some more struts if they get enough orders. So, my Cozy will have a LEZ nose gear. I'm going to reinforce the strut with an one additional layer of bi-directional. I'm guessing the caster assembly, other than the forks, is the same size. Any info on that would be appreciated.

Kent Ashton Posted June 28, 2019 Share Posted June 28, 2019 Just an idea: I think I would try to make a strut before I would mess with an EZ strut that I'd want to change-out later. The strut is likely S-glass, post-cured. http://aircraftproducts.wicksaircraft.com/product/fiberglass-kevlar-carbonfiber/s-glass-roving-filament-spool A U-shaped mold to make the shape does not seem hard to fab-up. We can come up with dimensions. Loop the rovings in the mold and wet-out as you go. Make it just a little thicker if you are nervous about it. I imagine Burt and Nat made their own first struts.

Mike B Posted June 28, 2019 Author Share Posted June 28, 2019 It is my understanding the struts are identical except for the end attached to NG6(A). I'll do some math and then test the strut and see how that turns out before I delve into making one. Quote Link to comment Share on other sites More sharing options...
Kent Ashton Posted June 28, 2019 Share Posted June 28, 2019 Aerocomposite shows $122 for a Long-EZ and Cozy III strut and $130 for a Cozy IV strut which leads me to think they are different. I have had both but I can't recall for sure. It seems the Cozy IV strut was thicker. Price lists below.

That's not how it works. Both you and I will just look for alternatives, as the build must go on without delay. If it was me I would stay up nights to cast a half dozen or so struts. We are building both so I have a raw LEZ NG strut just in case you want some dimensions prior to deciding which route you you will take.

Mike B Posted June 29, 2019 Author Share Posted June 29, 2019 Well, kinda. They won't make any more struts until there are enough main gear bows ordered. Quote Link to comment Share on other sites More sharing options...
Jon Matcho Posted July 1, 2019 Share Posted July 1, 2019 I have an untouched Cozy IV nose strut and can take dimensions. What are the Long-EZ nose strut dimensions? Unfortunately, in our world of practically orphaned aircraft, this is typical of how it works. These are small shops that need to make decisions for how and when to produce these unique parts of ours. If Aerosport were only doing Cozys and Long-EZs they'd be out of business by noon. With some patience and timing of your build you can likely delay this area. You can always design your own...

Kent Ashton Posted July 1, 2019 Share Posted July 1, 2019 Jon below is a DXF file of a Cozy nose strut. If you wouldn't mind, print it out and compare it to your actual strut. Let me know how close it is. There are no dimensions for either strut in the plans. I can send it in a PDF format if that will be easier.

Mike B Posted July 1, 2019 Author Share Posted July 1, 2019 DXF is perfect. A second-hand LEZ strut just arrived. I look at it tonight. Quote Link to comment Share on other sites More sharing options...
