More mechanical wooden silliness

[jdervin]

One of the things I like about the wood/masonite versions is that the iris completely closes. I doubt that it's possible to completely eliminate the center hole with overlapping metal leaves (though it can certainly get quite small).

For what it's worth, here is a different version of a professionally manufactured iris -- this one is intended for use in a stage lighting instrument.

NICE... Greg,

This project got "back burnered" due to a backlog of other work, but it has been itching at me the whole time.

I will definately incorporate the outside gear. Thanks for posting your files. I -have- to get at least one final piece made for the upcoming camp/s over here on the west coast.

I hear ya on the wood/masonite. I actually was thinking that the working parts on my final will be milled out of brass.

anyway yippee! I love seeing how others run with an Idea.

Thanks again for posting.

Greg,
Did you actually use the files posted to cut the parts for the unit shown assembled?? Thanks for posting by the way, but there seems to be a problem with the size of the large gear component as the diameter appears to be too small. The radial slots seem to have a smaller bolt circle diameter than the shoulder bolt holes in the base.
Can you check before I resize and screw something up??

Thanks again,

Tom in PA

Chris, I hope you get caught up with your other projects and give this a try again. I'm anxious to see some pics.
Tom, here is another file with the parts separated, nothing nested. All the holes mainly show location and I initially drilled all of them with a 1/8" end mill. I had changed the diameter of some of the holes when I changed the fasteners diameter and just drilled these out by hand. Don't change position of anything; maybe re-size depending on the fasteners you choose. Hope this explains what you need. If I can help with anything else, let me know.

Thanks Greg, I'll give it a whirl!

Looks like fun. Thanks for the files.

As long as we are playing with mechanical designs, I remembered seeing this and being fascinated. I'm sure some of you have already seen this but it might be worth posting for those who haven't:
