[JSK-koubou] is no stranger to making tools to improve their work, this latest video is another in a long list of such builds, just check their YT channel to see many other examples. The tool I will focus on this time is a semi-automatic grinding machine (video, embedded below), which is very convenient in many situations.

Many of us have encountered some difficulties when using angle grinders for straight-line cutting, especially for softer materials, because sometimes it is difficult to have a good "feel" for the way the cutting is performed. Once you start cutting, the thin blade will tend to "track" in the groove, so if it starts a little bit, the entire cut will fall off. The most annoying. Anything that helps to maintain a straight line and a square shape will help a lot. The additional function of the electric drive can achieve a constant cutting rate and may improve the cutting quality.

Since the operation is non-interfering, you can set it up and let it do its own thing, and at the same time you have to step aside, away from splashing sparks, noise and the possibility of blade chipping, in case something unthinkable happens. All good things.

The detailed construction video shows the structure that looks very sturdy, and there are plans available on the accompanying website, but they do require a small donation of 1,000 yen (less than $10) to download them. Given the utility of the tool, this seems to be a small price. We really like to build certain parts of the video, where the tool is used to cut your own components because it is built in order. Smart things! Another interesting technique is the use of flame-heated (Stanley) blades as the belt terminator. The blade is a bit hard, but it is a consumable and can get the job done, so it is enough for us!

In terms of parts, there is nothing special here. It is easiest to purchase through ordinary machinery suppliers, but we think you can also find most parts on eBay. We think this is the kind of build that works well in your local Makerspace, so maybe you can think about it?

Tired of manually cutting off? Need to provide an overkill solution for ordinary work? How about an automatic cutting saw? If you need to defend against powerful angle grinders, then maybe Proteus is the ticket?

Thanks [Keith] for the tips!
