This jig is designed to use a disc grinder safely. There is no need to hold down the material by hand, and the handle is ergonomic and easy to use. The slide moves about 250mm. Wide materials can now be cut with high accuracy.
Epoxy resin and aluminum are used for the linear bush housing. In addition, a thrust bearing is used for the rotating part, achieving high accuracy and smooth rotation.
The linear bush has a dustproof felt bush attached. Thrust bearings have a structure that prevents dust from entering. Thrust bearings are inexpensive and cost less than 600 yen. You can make it cheaper than it looks.
