Hello all, I was trying a faster method for dross removal on 16 gauge other than grinding. It always seems like grinding results in making the dross more of an issue. I tried a needle scaler. I let the piece lie loosely on my table and lightly run the scaler across the surface of the piece. The harmonics from the vibration remove most of the dross and what’s left I just hit as needed directly. Very rapid removal and it doesn’t “weld” the dross on line grinding does. Harbor freight sells these fairly cheaply. I have a video to load but it does not appear to be an option of attaching. Anyone that wants to see the video pm me. It’s pretty impressive how well it works.

Yep, same here. Stay away from the wire cups, they will catch the details and try to take flight.
If you have to grind off your dross, you need to adjust settings.
Most of my work is all pretty detailed 16 gauge which is dross prone. My 10 gauge or thinker stuff you can flick the dross off (if any) with a fingernail.

My dross tends to be very brittle and when dropped from chest height to the shop floor, most of it comes off. Chipping it off with a chisel and hammer also works before I go to the grinder last.
Try it.

I also use the drop method, works well for me. I have also used a knotted wire wheel.
I do quite a few part out of 1/4 I use a concrete mixer full of scrap cuttings. Quick easy and very noisy.

These ideas are great. I usually just use my welding pliers to break them off.

My arms got tired holding this contraption over the workbench. When I tried to flip it over the gas leaked out of the tank. I think next time I’ll use the electric mower it’s lighter!

I put my cuts into a 30% vinegar (straight) solution overnight. Then, use the knotted wire wheel to remove dross. Easy peasy. Even the occasional sharp turn tough stuff seems to come off easy. Like the needle scaler idea for the “settings weren’t right” problem dross though.

I do vinegar on everything I do except for like tractor parts and stuff. Removes mill scale and also makes clean up a breeze…
