How did you age the brass for the blades?
JBantha1 year ago
I'm in the making of my very first pair of Steampunk goggles. I've made some prototypes on paper and leather, but until now I'm giving brass and copper a try and I've found quite difficult to curve the metal into the cylindric shape it has to cover the eye.
so I have a question, which is the ⌀ of the cylinder you are using in the 15th picture to strap the metal around? Since I'm more likely to go and buy a piece of solid aluminium to have it always at hand I prefer to have the measurement someone is already using instead of buying something too small or too big, since money is quite a factor for me.
Thank you. All of your work is inspiring and easy applicable in many other context.

The diameter of the aluminum "blanks" 65 mm.

I'm afraid I don't quite understand the iris. so the pins for the leaves sit on that outer ring and then there is a second pin on the other side of the ring which sits in the lower plate with slots cut in it? also how would one make the iris close fully? It looks to me like yours still has about a 1/4" hole when its in the most closed position you have. You make the most intricate and amazing pieces! keep up the good work!
gogglerman (author)  sparktech2 years ago
That's right. The fact that I have used a relatively thick sheet metal. If we make the diaphragm blades are very thin, it will shut down completely.
Thank you.
all these amazing projects of yours (especially the watch) but no instructables! D: now i will be tormented by these... well, guess i'll try to make my own XD

wow, that cam plate is awesome! how did you make that?
Hoggster2 years ago
Are the leaves made of metal or wood?
gogglerman (author)  Hoggster2 years ago
The "leaves" are made of brass. Of course:)
Oh thank you, sorry For posting alot of questions on your other masterpeices, I just really love your work!

Brass, I should be able to get a hold of that :) thank you!

What tool did you use to cut out the numerous blades so perfectly? Amazing workmenship by the way.
gogglerman (author)  cod2897222 years ago
Each blade is cut with scissors and then they were stacked together and processed by means of bits Dremel.
Would you mind explaining how you went about making the cam? (The lower, slotted ring.).
I would appear he used a hacksaw or mill and only cut part way down
As for the forming I'm not entirely sure how he did that. from the inside it looks cast.
gogglerman (author)  robotmastern2 years ago
If I understand what I mean:) The ring consists of three parts, connected by means of tin solder and a powerful electric soldering iron. The slots for the axle aperture blades are plotted with a thin cutting disc, angle grinder.

I do not understand what was going on. Put the question more precisely. Please.

Incredible....I've seen plenty of goggles but urs is top dog. One question tho: Did u make the leaves for the iris yourself or did u get them somewhere? What material are they??
gogglerman (author)  vistaview2 years ago
Thank you. On the photo you can see that I made them yourself. I don't use off-the-shelf parts. Petals (blade) aperture cut from sheet brass 0.5 mm

This seems to be a professional explanation of the function and repair of irises, if anyone else is having the same difficulty I was in picturing the inner workings in action.
Thanks for the url. It does make things a bit more clear.

Great to have some behind the scenes pictures! If you need help with writing english instructions, you could ask from help in the forums.

(I am taking a guess you are based in a non english country?)
gogglerman (author)  gmjhowe3 years ago
You are right, I from Russia. Thanks for the help offer. As required I to it will use.
awsome work my fellow russian
as would i assist you with any English you need help with, as for all the help you gave me (Tesla3fox deviantart) though i may throw in a little old and middle English, though that might go quite well with the steam punk.

I made an instructable off of a template like this except it is made of paper, if anyone needs help building this, check out my instructable, just use metal instead of foam core
biozz3 years ago
do you have a template for the blades i can have?
gogglerman (author)  biozz3 years ago
It is possible to take a template here

where did you get all your brass parts?
gogglerman (author)  didgitalpunk3 years ago
Sheet metal is used. The brass can be got in specialized shops, or points of reception of a breakage of nonferrous metals.
ok thanks !
rapidkhan3 years ago
how thick is the brass plate? brilliant idea by the way :)
gogglerman (author)  rapidkhan3 years ago
Diaphragm blades are made of a 0,5 mm sheet brass Other details --1,0-2,0 mm.
Thx.
Hisart3 years ago
Nice photo record of a very cool idea!

Let me guess, one end of the iris blade is attached to the outer face ring and the other end just has a peg on it that rides in the second ring? The second ring has the slots cut into it and also has the lever attached to it. correct?

Please post some images when it is completed so we can she what it looks like when someone is wearing it.

Thanks.
