Free Ventus wing tie downs

[Matt Herron Jr.]

One or both of these beautiful wing tie downs free to a good home (see image here). https://farm1.staticflickr.com/954/41049064624_60348e0cd6_z.jpg You pay shipping.

I made these for my Ventus C (which I no longer have) because I wanted a fast, simple and secure way to tie the ship down. Simply remove a winglet, insert the tie down into the winglet tube at the tip of the wing, and flip the adjustable clamping lever down. the internal "O" ring expands and securely locks the device into the tube without any risk of damage to the wing. Made from Stainless Steel and Delrin, they will last forever. I kept a set in my handout kit as well.

Sorry, but the wing tie downs have been claimed. If there is a lot of interest in this, I might be able to document the design for those handy with a lathe. Let me know...

Cheers,

Hi Matt

Just have to say what a slick piece of work :-) Very impressed with them and think I should do something similar for my little Ventus a and my Nimbus 3D

I’d like to get a set of plans. They look pretty nice.

[Jeff Morgan]

Very clever. Sounds like a no-brainer purchase.

[Dan Marotta]

Those look stunningly good!Â* I'm almost willing to buy a Ventus just to
get those. :-P

OK, there is enough interest that I am posting instructions on how to make these. It is actually pretty simple, but you will need access to a lathe, drill press, etc.

1) download the purchased parts list here (https://www.dropbox.com/preview/Public/wingtip%20parts%20list.png?role=personal) and order the parts from McMaster. You only need two of the carabiners, or you can substitute a SS threaded link as I did: PN:8947T26

2) Machine the three parts (X2 each) from drawings provided here
https://www.dropbox.com/preview/Public/tie%20down%20jack.PDF?role=personal
https://www.dropbox.com/preview/Public/tie%20down%20spacer.PDF?role=personal
https://www.dropbox.com/preview/Public/wingtip%20tie%20down.PDF?role=personal

for the SS wing tip tie down, just print out the drawing, paste onto the sheet metal, and use it as a template for drilling and shaping

3) assembly

a) disassemble the cam handle and thread the rod into the tie down jack (thru the end with the O ring step) so that it protrudes about 1.9 inches. Re-drill the 1/16" hole in the tie down jack thru the rod and press in the spring pin so the rod can't unscrew. make sure the pin is recessed below the surface of the Delrin so it won't scratch your wingtip tube wall.

b) drop the O ring over the rod onto the tie down jack

c) slide the tie down spacer over the rod.

d) slide the wing tip tie down over the rod.

e) re-assemble the cam handle onto the rod and screw it in until the O ring is squished when the cam handle is engaged

DONE!

4) to use this gizmo, remove wingtip, and slide in the tie down. Flip the lever downward and adjust as needed for the right amount of axial retention.. It should be almost impossible to pull out the tie down from the wingtip tube. Attach a rope thru the threaded link and secure the wing. I like to use a rolling hitch to cinch the wingtip down easily. See: https://en.wikipedia.org/wiki/Rolling_hitch for how to tie this fabulous knot.

Let me know how it goes!

Cheers,

Matt

The dropbox folders are not existent

Hi Matt,

I tried accessing the dropbox files but the folder showed empty. Perhaps it's a user problem at my end...

Thanks,

George
