Keel GoPro Cam mount
Thought I'd share the GoPro Cam mount I designed for Henry's wing with you guys. I posted it on fb a while back, but I'll post it here as well.
The plug is a second revision. Upon looking at Henry's wing, I decided to design it with a couple of features I thought were important. First, I added the large sealing cap so that the plug covers the entire diameter of the keel. This prevents air/water ect from entering the Keel. Also, the original through hole for the GoPro selfie stick is now a blind hole.
Pretty straight forward stuff. By all means ask questions.

Dude! That's like watching a "How its made" episode. Very cool Leo. You've got skills I've always wanted to learn. Maybe I'll do that when I retire instead of golf. :) 10 out of 10 cool points!
Haha! Thank you Scott! If you ever decide to get equipment, I'll be glad to show ya how. ;)

Yeah, Leo is an extremely talented man with many skill sets. If you can think of it, Leo could probably make it. He picked up flying as if he had been doing it all of his life. And humble about it all too!
Now I'm blushing! Thank you Rick! :D hahaha!
I've got a question. How much would you charge to make another one for me? ;-)
Hi TrikeFlyer! You know, I actually have no idea without sitting down and figuring it out. I used Materials I had, and actually made 2 of them after machining the one Henry designed/measured, which didn’t fit.
Both of the new ones I designed are one off's because there's no way to control the Keel diameters or the selfie stick to the kind of tolerances we need in order to keep the camera steady.
Having said that when it comes to one off’s typically I need to measure the wing myself so I can apply geometric tolerance. That’s the only way I can assure a perfect fit and it needs to be perfect in order for the video to be steady.
I would feel more comfortable if I could come up with a universal type, like I had stated before….for example a cam mount that had O-rings to take up the inconsistencies of all the different Keels out there.
The issue and the reason these are custom fit is because the Keel isn’t round. No tubing is. They’re oval technically by the slightest amount, but it’s just enough that the Cam plug needs to hit the middle dimension tolerance.
In short, even if I made one for you, without being able to measure the keel myself, I wouldn’t be able to hit the right dimensions for the fit needed.
He uses big words sometimes... I'm confused and stuff. ;)
Oh shush you! hahahahahahaha! :D

Leo, No problem, I understand. Very cool mount though. I would love to have one. I assume Henry had the cone custom sewn as well. It's impossible to one up that guy! ;-)
Where do you live TrikeFlyer? If I figure out a way to make it semi-universal, I'll post it on here. I'm not looking to profit from them, I want to see more of us making awesome videos.
Henry cut his cone with a pair of scissors, and used this tape called...."Tear-Aid" I think, and he lined the edges with the tape. No sewing. He did an awesome job...you can see the taped edges on the bottom right last picture of page 1 of the album.

Hey Leo. Ok, I'll stop being a goof and offer some real conversation as I really feel this universal keel video idea is worth your time. I've got some ideas for you to consider. #1 Can the slop in a universal size mount be taken up by two 90 degree offset set screws drilled into the keel and pressed into the mounts sides? I know everyone hates drilling into their keels but at least set screws aren't big. #2 I'm also thinking about a draw tight or wedge type unit. A bolt in the very front, inside the mount for the selfie stick area, is tightened up to "x" lbs (not much usually). That bolt draws forward a wedge (maybe two or three parts inside). Similar to how those concrete lag anchors work. #2b, The best one I can come up with though is probably similar to that wedge unit but instead two large rubber bushings that are drawn tight by the same bolt. Each one is squished between two hard, thick SS plates/washers. That squish takes up the slop and stops vibes at the same time. Of course it might cause vibes too if it's not squished enough... Just some thoughts. The universal problem is definitely difficult. Hey, they don't call me Wile E for nuttin!
You're sharp bro. No doubt. ;)
Yep, I've considered both of those.
The first idea with the set screws is the most logical however, in the name of safety they really need to be wood screws that bite into the pastic not set screws. Further more you need 3. Two like you mentioned, and one from below, that would eliminate left right slop plus the third to take care of up down. I can shorten the plug and eliminate the slot issue, if I went that route.
The con? Like you said.....are folks ok with drilling three .200 size hole, 1/2 inch in from the front into their Keels? For Henry's version, you can see I drilled one hole for the safety lanyard from the bottom, 1/2 in from the front, And Larry had no issue with that.
Larry's major concern was making sure air didn't enter the front nose of the wing. We made sure it can not.
The second idea. This can also work, but it leaves a few issues as well just like you mentioned and costs more to make because it's more complex.
So it's not that it can't be done, it starts to become an issue of, how much fabrication time does it take to make? Can you imagine the cost? Lame.
I also considered an external bracket that grabs the pivot bolts of the leading edge tubes, and forks towards the nose, but again.....not as practical as the plug.
Another one was, make a plastic bushing with a diameter almost as large as the keels only leaving like .05 clearance for epoxy ( like a shim). It would get bonded into the keel, then the plug would slip fit into the bushing's perfect diameter.
Again......do we want to bond to the inside of the Keel?
Its a pain I swear. I'm thinking though......
So I get a B+? lol. Just bc I'm always in learn mode... what is the major drawback to the squished rubber bushings on two points of the insert? That is my favorite option as it can adjust quite a bit. The tricky part is how to ensure it dosen't back out. Doable but a few tricks to lock it in. Fabrication wise, it seems easier.
Not sure which one you're reffering to.
I stay away from rubber if I can, simply because its a pain to machine. I also think it won't provide stable video unless the durometer is high...but then it starts getting kidna pointless.
So far the most practical in my mind is the O-ring version....but like we said it requires drilling the Keel.
