Reusing unnecessary items related to routers and trimmers : Yamada
Yamada released unnecessary items related to routers and trimmers. We are always grateful for his generosity.
Introduction to left-handed grooving plane : Dalton
Dalton showed us a grooving plane that he bought on the second-hand market in England.
He quizzed us on what we thought was different from a ordinary grooving plane.
The answer was a left-handed grooving plane.
There was also an explanation that there was a period when intermediate planes, with metal structural part mounted on wooden bases, were on the market for dozen years, before the transition from wooden planes to current iron planes in the West.
A dust collector for a circular saw table : Tani
Tani uses his homemade small circular saw table in his home workshop.
Since he uses it indoors, the biggest issue is sawdust, so he is working on creating a dust collection system.
The photo above shows an arm mounted on the room wall, securing the dust capturing unit directly above the circular saw blade.
If you mount it on the wall, it won’t get in the way of the circular saw table.
It has multiple joints and can move freely, and once the position is determined, the joints are tightened with wing nuts to secure it in place.
The joints move smoothly because of the smooth film (that comes out when using Salonpas) in between. A dust collection port is attached to the white pipe visible at the bottom of the device.
The port is made by transplanting the bristles from a bath brush into a plastic box. Designed to prevent dusts from leaking outside.
He is still researching the stiffness and density of the brush.
Octagonal chopsticks : SUGA56
SUGA56 made octagonal chopsticks. He made them octagonal to celebrate a friend’s 88th birthday, a milestone age in Japan. Also, octagonal shape has the feature of food being less slippery.
He needed three types of jigs and a block plane for production.
This is a block plane cover. Repurposed a silicone remote-controller cover from a 100 yen shop. Quite an idea!
Description of homemade dust collector : Matsushima
Matsushima presented a dust collector.
In the case of a cyclone type, a cone-shaped part (triangular cone) is usually placed upside down on top of the container, and as the chips pass through it, they rotate and fall into the container below, where they accumulate.
Matsushima’s device has a megaphone-shaped triangular cone that widens at the end inside the container, and the chips that enter the container go around the space between the skirt-shaped megaphone and fall down and accumulate. A reversal idea.
Other measures have been taken to prevent the entire container from collapsing due to negative pressure.
Homemade speaker made from MDF : Ebisawa
Ebisawa is an audio researcher. He disassembled a speaker sold for 300 yen at a 100 yen shop and installed it in a homemade MDF box.
One speaker is made up of two boxes and a connecting part, which are not glued together.
The sound quality changes by shortening or expanding the distance between the two boxes.
It transforms into a high-quality sound that you won’t believe is a 300 yen speaker. All the members were surprised.
Drill bit sharpener : Sugita
Sugita has been using the BOSCH drill bit sharpener for 35 years, and a few years ago he stopped using it due to running out of whetstones. Production of that product has long been discontinued.
After searching around, he found a replacement whetstone of the same size used in a similar product made by another company, so he replaced it and revived the sharpener.
After this explanation, he demonstrated how to sharpen a drill bit.
