Thank you for your kind words! The tong/benders that we are using in the video are from a Japanese brand called MORIMITSU co. ltd. Hope you're able to find them!
We would also like to mention that all sheet metal tools we use are crafted in Japan. The curved scissors are called "Yanagiba" (柳刃). The scissors that look like clips are called "Tsukami". Both are essential tools for Japanese craftsman.
Thanks for your comment! We have four different styles available for purchase at morikunijapan.myshopify.com/ The video was taken in Niigata, Japan where the manufacturing facility is located.
The concrete sidewalk is called "Inubashiri''. They are designed to prevent mud splashing from rain and to make walking easier. It was more common in old Japanese houses. It's got a quaint look and feel, doesn't it?
You are delicate with your bending and folding techniques. Very nice. With that said, silicone should not be the sole sealant for copper seams. Soldering allows expansion and contraction with a superior life span
Thank you for you comment! When using a ridge cap, it is important to fold back the counter flushing and caulk well. Installation also requires layers of high-performance underlayment. Pure silicone caulk is much more resistant than urethane-based one, and is often used in sheet metal work including copper. The corner ridge (or hip cap) is called "Hamaguri" in the traditional Japanese construction method. In the original construction method, both ends of the Hamaguri or the hip cap are also interlocked with the main body, but our corner ridges are designed to use caulking for better workability. Even with the traditional construction method, the hip caps may be where the leakage occurs so we recommend that you use a high-performance underlayment beneath them.
The tong is called "tsukami" in Japanese! We don't know of any online shops that ship internationally but Morimitsu is the most popular brand for tongs in Japan.
Thank you for your suggestion. Here is the link to a version without music. I hope you find this more enjoyable. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7AMWpt9yNnw.html
Thank you for your comment! Corner ridge is what we call "hamaguri" in traditional architecture. Traditionally, all four seams need to be locked in but this is extremely difficult to adjust and takes great care. Our roof shingles are improved from this beautiful traditional method, and made to be installed easier. In either method, though, this area needs some anti-rain measures such as doubling underlayment. Please let us know if we can answer any more questions! monji.morikunijapan.com/contact/
The curled tail ("hamaguri") is a traditional method that highlights the beauty of the curves. It is an advanced method, but because of how this small part needs to be locked from all four sides, there are many joints. This leads to higher risk of rain leakage. On the other hand, MONJI's method is much easier -- the sides do not need to be locked, and they just need to be caulked. It requires higher level of underlayment, aware of the risk higher than the traditional method. Thanks for watching!
We are not sure where those Japanese metal roofing tools are available outside of Japan. Please let us know which tool you are interested in, and we can possibly source it for you. Thanks for watching! info@morikunijapan.com
Thank you for watching our video! When using a ridge cap, it is important to fold back the counter flushing and caulk well. Installation also requires layers of high-performance underlayment. Oil-based caulking will cause stains on the copper roof, so it is better to use pure silicone caulk. Pure silicone caulk is much more resistant than urethane-based one, and is often used in sheet metal work including copper.
Thanks for your interest in MORIKUNI products! The major supplier for tongs/benders in Japan is named Morimitsu. I hope you'll be able to check them out!
