Hello All,

Anyone here know of a source for transparent or clear 3" OD diameter, blunted ogive or pointed ogive nose cones (perhaps, even a parabolic shaped)? I've searched online for them but have not come up with any. I also searched the Forum here to no avail. I will keep trying nevertheless.

Thanks

Try looking at clear plastic fillable ornaments on Amazon. I've used them before. Some are egg shaped and might work for you. Others are round and I've used those for nose cones.

I'll check it out right now...

What are you trying to build. I could build one from my mold but it would not be clear. Do you need clear or opaque?

Another option could be large plastic wine glasses. Cut off at the stem and you have the start of a good nosecone.
Not sure if they go up to 3 inch but since COVID it wouldn’t surprise me.

These aren't quite what I am looking for, I think.

I need it to be clear as possible for the 360 camera I want to install in it.

I think that may be a viable option. In fact, I have some somewhere in a box. I need to locate. We recently moved and there are things missing. But your mention of them reminded me of a purchase I had made a year or so ago.

I've thought about a plastic bell jar for something like this, e.g.
If you're willing to live with a hemispherical shape for your nose, there is a world of clear plastic domes out there. Just search for "clear plastic dome. E.g.: https://kitkraft.com/products/3-76-2mm-clear-domes. I would think these are likely to be more optically pure than plastic wine glasses or stuff like that. If you search for "camera domes" you can find really good quality stuff, but it tends to be expensive.

Whether this works in your application depends on the shape of your camera. If it needs a lot of space above the lens, then hemisphere probably doesn't work.

For a camera, would a section of tube be adequate? I'm wondering why the nose cone, and a cylinder is probably a lot easier to find.

The one reason I can think of is to point the camera straight up. If that's the idea then the hemisphere options are probably your best choice for minimum optical distortion.
We have a 2.6" nose cone.
Wow, I didn't know you guys have anything besides motors. Now I have to go check out the rest.

OK, I checked your Products page, and I still don't see anything but motors.

CTI: I couldn't find nosecones on your website(s). Can you provide a link?

No you won't find them on our website, but most of our dealers carry them. 38, 54, 2.6" and 75mm. Currently the 75mm are only available in black.

you could try this clear printing method. Not used it , but looks promising.

I have often thought about starting a thread asking the same thing. Not just for cameras, but actual really clear nose cones, not just domes. There's a lot that could be done besides cameras, thought that is certainly the most utilitarian. But a strobe could be mounted in one, or a kids' themeed rocket, stuff like that...

Hello all,

I've read all of the posts and there are quite a few. So, I'll answer a few of them

I've thought about a plastic bell jar for something like this, e.g.
This looked good and I might have gone with that if I could trust my cutting it without shattering it. Then the next post looks like it may work better...

If you're willing to live with a hemispherical shape for your nose, there is a world of clear plastic domes out there. Just search for "clear plastic dome. E.g.: https://kitkraft.com/products/3-76-2mm-clear-domes. I would think these are likely to be more optically pure than plastic wine glasses or stuff like that.

This, I may try to utilize. I may ask myself why I would want to capture sky but the camera I'm looking to incorporate will have a 270-degree arc and 260-degree horizon. Actually, let me post a link and image of it here:

If you just want an optically clear dome, these are readily available. If you want a dome at a very specific size, it's pretty easy to do it yourself with a hot air gun( normally used for a paint stripper) ideally adjustable temperature but not critical, and air line, the plastic of your choice (3mm acrylic is easy).
Commercially, you'd heat the plastic in an oven , then transfer to a table with an air feed and a valve to control that in the center, a clamping ring and a bunch of clamps to clamp it quickly while still hot.

Gives a good demo of it.

Warning THIS Is NOT SAFE. I never said it was. All below at your own risk. Leather gloves, Safety Specs, Ear muffs.... If you're not happy with this method, I didn't MAKE you do it. This is for people who trust their own judgement on when to cross the road and do not NEED a green man to MAKE that decision for them.

You can do the same with a piece of 1/2 " ply with hole the correct dia cut. Sand it so only one side has the finished dia and the other is fully smooth radiused. So the bottom side will have a dia say 3/4" bigger. cut another piece of ply with a hold at that bigger dia and finally a last backing piece with your air hole and valve( a NON safety air duster works well).
Get double sided foam tape and tape your perspex (with the paper removed) to the Bottom of your finished radiused mold. apply more foam tape to perspex and seal to next larger hole section. Then attach that to the bottom. Now drill and bolt through all.
Put some leather gloves on. Heat the perspex up with the hot air gun. Keep it moving not too close. Get it all at the same temperature and a good wobble on it. Inject air and it will start to form a dome. You can adjust the shape by continuing to keep it hot as you inject the air in the area you want it to go. This is a finesse move for advanced players. You can use the mold bits as a template to drill your next dome.

All usage at your own risk and no expensive equipment needed.

Sorry about the bad link,

yes, it's here:
360fly Panoramic camera

but, on Amazon, I found it for <$60.

In the meantime, the clear housing/nosecone is still up in the air.

But, This is what I found at a Dollar Store. After cutting of part of the glass, this, looks a bit obscene might be something to try:

The bottom opening measures almost exactly the 3" needed to mate up to the airframe. Now, all I can do now is hope this camera will fit inside and THAT, may be a problem as I did not get the dimensions before purchasing it. I THOUGHT I did but, well, we'll see...

If you're hoping to use the images from directly forward, that looks like a really bad idea. Try the camera on a table covered with the glass ad see what you get. I feel confident that you won't like it.

Cut off the rest of the stem. Use progressively finer and finer sanding sponges to polish it back to clear. And then you still won't like it, because of the thicker material inside the glass where the stem was.

I'm assuming it's plastic Glass. A glass Glass may fall foul of the materials permitted rules.
And also against the good sense rule.

The dead center portion is actually irrelevant so that "tip" is unimportatnt for me and as long as the vehicle is oriented verticle or nearly so, that should allow me a successful 360-degree view of the horizon. But, you brought up a good, other point that might keep this NAR/TRA attempt separate and make this camera thing a separate project.

I know that some companies are 3D printing lenses for glasses. I don't know what they do to get rid of bubbles etc. It'd be worth looking into, to see if something similar can be done at home.

Do you already have the camera and have you been able to get it to work well? I was curious because the reviews (recent ones, that is) on Amazon are pretty horrendous and imply the product is discontinued with zero manufacturer support. If you've gotten it to work though, it might still be a great option at $60.
