Manufacturing process of handmade eyewear

[@Emilio-wb7lu]

Hello, I have decent knowledge of glasses for the most part, however I have many acetate glasses laying around, that could be re-used. What material do you use for polishing and restoring shine? I can polish but that leaves cloudy, white tracks.

Thank you very much😄

[@χριστοφοροςτσεκος]

how do you even get started in a business like this , i've been an optisian for the past 6 years but i am interested in making glasses , beautiful video

[@EyewearCraftsmanJapan]

Thank you for your comment. When I first started making handmade glasses in earnest, I apprenticed under a master and trained for one week, then received homework for the rest of the month. After that, I trained for 10 months, living in for one week and doing homework for one month.After that, my master retired, so I was introduced to his brother disciples, and I continued to train and manufacture glasses. It took about 5 years to get things going smoothly, but now we manufacture everything in-house except for the plastic plates, hinges, screws, and metal parts.

[@John-mj1kk]

Do you know how some manufacturers place a (metal?) core wire inside the legs of the frames to add further support? I've searched to no avail. I suppose this is something very hard to do manually.

[@Rene.Mortel]

I know next to nothing about making frames but I suppose they sandwich sheets of acetate around the metal core and it's all bonded together with acetone, heat and pressure.

[@empe3332]

If its cheap frame made by injection plastic the process is simple. place metal part into the tool/mould, press green button and molten plastic will fill the cavity of the tool/mold.

[@EyewearCraftsmanJapan]

Am I correct in my understanding that a metal core is placed inside the temple? I split the plastic plates of the glasses and put the metal inside, then applied a solvent and glued it together using an electric hot press.

[@EyewearCraftsmanJapan]

As you say. I also make temples using this method.

[@ojoguandule]

How long would a class to learn this process take 2 weeks or two months ? I would take the trip to Japan to learn

[@EyewearCraftsmanJapan]

Thank you for your comment. First of all, you need to understand the entire process of making glasses and be able to use files and buffs well. I think it will take a few years before you can use each tool one by one, but if you learn them while making them, you will gradually be able to make beautiful glasses.I think you can learn just the process of making glasses in two weeks, but I tell my students that it takes at least five years to become a full-fledged craftsman.

先生、こんにちは、私はちょうど手作業の眼鏡に接触して、あなたに1つの問題を教えて、ヒンジが杭の頭の上に埋め込む時、一部の材料を押し出して、私が押し出しられたこの部分の材料を取り除く時、醜い痕跡を残して、何か良い方法がありますか?

[@EyewearCraftsmanJapan]

こんにちは。 眼鏡の蝶番を埋め込む際は、埋め込む部分の容積を計算し先に穴を開けます。 私が使っているのは日本製のベーシックな蝶番で3mmのエンドミルで深さ3.1mm掘っています。 こそに蝶番を埋め込めば、押し上げられた生地が出てくる事は殆どないと思います。

[@lucabarrel2797]

beautiful! what tool do you use for the internal cut of the frame? to fit the lenses. your work us awesome !

[@EyewearCraftsmanJapan]

Thank you for your comment! First, chamfer the lens part. Next, use a special blade to dig a groove in the lens. Thanks

[@davedyall8332]

Great work!! I was scouring the internet for that same tool!!! It looks adjustable in the video for frame thickness. Do you happen to know the specific name of the maker of said tool? Thanks. Great video!!!!

[@onzalab]

@@EyewearCraftsmanJapan Did you know the name of this special tool? where we can find it? thank you! This video inspires me!

[@louisvictorduquet2801]

what thickness is the acetate plate you use?

[@DP-hw9uq]

Beautiful! No wire in the temples?

[@EyewearCraftsmanJapan]

Thank you for your comment. The material of the glasses made in the video is celluloid, and even if there is no core inside the temples, there is no problem because the material is strong. It is said to be a material similar to buffalo horn.

[@DP-hw9uq]

Thank you for your reply. Is it celluloid or cellulose acetate? Because looking at the video it looks as malleable as acetate, but maybe even celluloid is so malleable?

[@EyewearCraftsmanJapan]

This is made of celluloid. If you use acetate, you will need to insert a core wire because it is a soft fabric, but if you use celluloid material, there will be no problem.Celluloid is also a flexible material that is easy to process and adjust.

貴重な動画とても勉強になり何度も見返してます。質問ですがシューティングの機械がない場合他にどのような方法で芯をテンプルに入れれますか？私は垂直に細い穴を空けて柔らかくし、入れる方法を考えました。 ご教授よろしくお願いいたします。

[@EyewearCraftsmanJapan]

動画視聴ございます！シューティングの機会はかなり大きなものになるので、私は導入していません。現在芯貼りと呼ばれる方法でテンプルの中に芯を入れています。4mm生地を短冊状にカットし、横から刃物で半分に割ります。昔ながらの製法です。

[@desbailes5542]

Thank you for the video. I am making a frame but where can I get the acetate nose pads you glue on? Many thanks

[@EyewearCraftsmanJapan]

Thank you for your comment! I bought nose pad japan factory and glue "Acetone70% , Methanol 20%, Methyl acetate10%" using a mixture of three solutions. Thanks

[@JohnFrancisDuran]

What sand grit used for scratches and finishing? And rubbing compound for tortoise acetate

[@EyewearCraftsmanJapan]

Thanks for your comment. When polishing, I use wet mud for large scratches. The name is Boshu powder. The finishing compound used is the finest mirror finish sold in Japan.

[@bildal6862]

Could you please tell me which glue you are using for nose support?

[@stratobee]

He's probably just using acetone as that turns acetate into an adhesive. At least that's the traditional method.

[@EyewearCraftsmanJapan]

I use a variety of solvents, but the one I mainly use is called Funere. I use a solvent called Funer. A mixed solvent of methyl acetate, acetone, and methanol.If each solvent is available, methyl acetate should be 20-30%, acetone 70-80%, and methanol 5-10%.

[@mohammedegyptian2527]

[@DeepakKumar-yi6pr]

[@EyewearCraftsmanJapan]

The product name is written as Nietkopfmacher. and Flearning punch. That's a unique name. The company is listed as B&S quality made.No,212504.

[@ugoliniRiccardo]

Is there no iron in your arms?

[@EyewearCraftsmanJapan]

Celluloid glasses do not require metal cores in the temples. For items that are too thin, a metal core may be inserted.
