I’ve got a hand-held angle grinder (Makita LXT, 5”). I’m using a wire brush in it to finish a long thin bit of steel (rectangular profile, about 3ft long, 5x15mm tapering to 5x5mm - it’s a sword blade, but it’s not sharp, so that’s probably not relevant)
It’s proving difficult to clamp the workpiece as it’s very thin. (Before everyone suggests ways to clamp it - I’ve got a metalwork vice, but I’ve not got anywhere to fit it outside where I use the grinder, so I’m using g-clamps. Also clamping round the part I’m working on means the grinder is mainly in contact with the clamp, which wastes effort and makes controlling the grinder harder. It’s difficult to grind beyond where it’s clamped as it resonates. So the most effective method has been clamping either side of the part I’m working on, but this is difficult).
I think it’d be easier if the grinder was fixed, and I brought the work piece to the grinder - I’d be able to hold it either side of the part I’m working on, and to feel the movement of the workpiece and compensate.
However, I’m conscious that this isn’t what the tool was designed for, but I know bench grinders do exist (I don’t have a bench grinder), and I think they give more control (which i presume is why they’re used for sharpening knives etc). Is this approach safe? If so, are there any precautions I should take?
