An Extremely Useful Shop-Built Belt Grinder

What’s green and black and used all over the shop? It’s [Make It Extreme]’s newest build, a scratch-built belt grinder. And as usual, the build video gets us in the mood to cut metal.

We’ll go out on a limb here and state that the lathe, and not the belt grinder, is the essential metalworking tool. That’s pretty clear from this build – the running gear is machined entirely on a lathe. But as central as the lathe is to machinery making, belt grinders like this one have to rate right up there in terms of shop utility.

You can sharpen with them, quickly remove stock, clean up welds, form chamfers, and remove rust and corrosion. They’re great all-around tools, and with the quick-release idler feature that this one has, fast belt changes for different jobs make it even more flexible. We’d like to see more adjustability in the work table – the ability to angle the table relative to the belt is very handy – but in all this is a great build and a nice tool to have.

On top of it all, watching the [Make It Extreme] builds – like this sandblaster, spot welder, or belt sander – is like high-speed shop class. There’s a lot to learn, although we have to admit that welding in shorts and a T-shirt gives us the willies.
