Manufacturing process of handmade eyewear 

Thank you very much😄

Thank you very much for your comment.

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

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。

Thank you for your comment. I believe this is the result of years of training.

@@EyewearCraftsmanJapan i dont know if you would believe me but its my dream jop iam ready to spend thr rest of my life doing this eager to learn it im trying to do it its abit difficult right now but its in my blood i know it god pless you man

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.

​@@EyewearCraftsmanJapan, hi dear pls share your contact details

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

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!!!!

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

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.

Thank you for your comment! I am teaching in Japan now, but in the future I would like to create a place to teach technology in the United States.

@@EyewearCraftsmanJapan if you started a brand here in Egypt it will be so successful..we can collaborate in that ..the Japanese work has alot of respect here

Thank you for your comment. I work in Fukuoka Japan.

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.

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.

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.

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.

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

Thanks for your comment. I have a thread cutting tool, so I cut the rivets with it.

Thanks for your comment. I'm honored that you are interested.

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。

Typically they use acetone to melt the plastic for bonding

Thanks for your comment. I use a solvent called Funer. A mixed solvent of methyl acetate, acetone, and methanol.

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.

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?

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.

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

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%.

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.

是你刮的那個文件嗎？文件由日本傳統工匠手工製作。現在文件工匠退休了，我拿不到。

Cellulose acetate.

Thanks for your comment. I mainly use celluloid. I also use acetate and buffalo horn.

We call "KISAGE" which this tool is made of steel and uses a knife to smooth out rough surfaces.

Thanks for your comment. I started cutting by hand using an NC machine about three years ago. The manufacturing method introduced in the video is a traditional manufacturing method that has been passed down since ancient times.

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

@@EyewearCraftsmanJapan is acetate the same? Would you need to use a metal core with acetate?

Thanks for your comment. This tool is also sold by a company called B&S quality made.

@@EyewearCraftsmanJapan Thank you for sharing! I am a beginner of handmade frame in Taiwan. Inspiring video, thanks again!

Thanks for your comment. Currently, we only have teaching materials in Japanese, and we are not yet ready to provide them in English or other original languages.
