How to make Mechanical Iris Diapraghms?

[Derranged-Gadgeteer]

Absolutely perfect my good sir!! I thank you profusely!

[Robo Von Bismark]

No problem. What are you intending to make?

[Derranged-Gadgeteer]

A lid for my forge.

I plan to use metal parts to make plaster molds, from which I will slip cast the requisite parts in refractory.  I'll have them fired when I get back to school.  (We've got a/the world leading ceramics college) and I'll be sure to post videos and pics when finished.

Please post the pics when finished, that sounds amazing. If you need the original CAD files just email me.

Mayhaps one could use the iris in a way, as to actuate the flow of lightening through the end of a blaster?
Or to concentrate the fire of a Wide-Beam blaster

The thought just popped into my head that an iris would make a great cover for a peephole on a door.

Someone comes knocking, the iris springs open with a great *shiunk* type noise to expose an eye staring out at the caller. The door swings slowly open.

I chuckled as I noticed this as I was looking for how to build an iris, because that's exactly what they did on Prototype This!

You can kind of see it here, located in the "Lair," but you can't see it in action. I know there's a video of it working somewhere, but I haven't been able to find it yet.

Mr Bismark, would you happen to have any further information on the assembly of that iris? It's just the kind I was looking for

I really need to scale down those pictures. Sorry about that folks

JingleJoe most of the info is here:

If you need the original template file I created I can email it to you. Its EPS vector format, so its easily scalable in Illustrator, Coreldraw or AutoCAD.

The most important thing to get right is the shutters. I cut them from steel and brass shim (about 0.35" i think). The studs were made from nails that i hammered through the shim. This ensued a tight fit and a bit of support along the nail shaft. I then cut the nails at both ends, leaving about 5mm sitting in the hole. The 5mm nail was the pushed flush against shim face and a blob of epoxy putty smeared over the surface to secure it. This has to be smooth to ensure that the shutter works well. Also helps if you sharpen the edges of the shutters for a smooth action (a dremel tool is good for this).

When I do my simple two shutter "eye" version I hope to explain this better with pictures.

Dear Mr Bismark,
i LOVE your iris!!! i've been looking to make one for ages!!!
would it be possible for you to email me the template file as i can attempt to make an iris as good as your please?
Thanks

I was going to send you a PM but there doesn't seem to be anywhere you can attach a file. I also tried to upload the files to Photobucket and provide a link, but it only takes image files (not vector art).
Send me an email address and I will send the files directly to you.

uhuhu, after i reinvent the wheel I find this thread with google 

my 2 cents design in corel draw: http://www.steampunkworkshop.ro/images/iris.jpg I need an iris with an aperture of 100mm so yesterday I design my own but mabye some one else need it too.

also in pdf format, its al curves so can be inported in any vector program

http://www.steampunkworkshop.ro/images/iris.pdf

[Professor Fzz]

Nice.  But haven't you got the slots on the outer ring angled the wrong way?

[Spiritus]

dont know, I never design one before and I suck at searching plans on internet, but I think your right, because I was thinking the cover goes like this
http://img204.imageshack.us/img204/7919/iris2n.jpg
but I see your point because my outer ring is in the same position,I rotate the cover not the ring  
Edited: you are right, I will modify soon
Edited again: I fix it, thanks for help

That looks like a 20 blade design I saw on the web.











Movement is similar to the "Stargate" iris:



I drew up a basic CAD drawing but never made it

[CptFancyBreeches]

fantastic, can you email me the templates also?

[Fcimino]

I do like the idea of variations on irises, such as animal eyes. I am working on a simplified version of this earlier one I made. Using only two shutters instead of the twelve, Im hoping it will look like an almond eye







Those materials are taken from a camera lens??

[mudslag]

Here is a cad file I have had for a while, have fun

[mudslag]

grr no edit button, anyway there are 2 different cad files with slightly different iris's in it

[Captain Morgan Arkwright]

Robo Von Bismark,

Just wondering, what sort of tools and materials did you use to construct your iris? I'm looking to make a pair and just wanted to know what the... tool cost would be for such a thing.

Thanks,

Captain Morgan Arkwright.

This is the diagram i used for my twelve blade monoggle. It was traced from photos from the internet.

Robo Von Bismark and others,

After much searching on the net I found this thread and everything made sense. I used this image to build my own iris mock-up. However, I'm trying to make some changes in the dimensions. I was wondering if you have the vector/cad file for this and you don't mind sending it to me? my email is aboutthebirds [at] gmail.com.

Thanks in advance,

Al

Thanks for the reply. Actually I was looking for the vector version of what Robo had posted (post 64 I believe). I have built that with paper and it works well, I just need to do some adjustments and don't want to screwup the location of the holes and curves by retracing the image. I've downloaded your cad files as well and will take a look at those as well. Thanks.

Regards,
Al

cool, thread, heres a video of one that i made before using an early design from the shopbot forums, but i think it would be fun to transfer it over to thinner acrylic and made it more like the 20 blade design you guys have photos of

Mechanical Iris - 1st version

[FightingDrag]

just looked through all of this, its beautifull!!!

[Dr von Zarkov]

If you can be satisfied with a three-leaf iris shutter, Cardnetics offer the same as business and greeting cards. They may also be had as pre-scored, punch-out kits.

I'm not advertising for this firm, but suggesting a means to obtain a template from which one may construct card, polymer, or metal irises. One brass Sovereign to the steampunker who posts a usable pdf template!

[Joeynana]

This has to be one of the more impressive iris constructions I've seen considering it's simplicity.
