Re: Dross Scraper
Get an air chipper from Harbor Freight..... works great. Spray pieces with anti-splatter.

Re: Dross Scraper
I use a old butcher knife to knock off heavy dross. Use it like a machete swing in side to side. Say you are cleaning the outside of a piece strike the metal pushing dross away from the edge. I works good for me. The knife needs a very stiff blade and not real long.

Re: Dross Scraper
I just use a cup shaped wire brush in a grinder.... The problem most folks have with the cup brush is that they just lay into the dross really heavy... That actually makes the dross heat up and hang on harder... Next time try this... Just barely touch the dross with the wire.... Work at a 90 degree angle to the dross, and most of it will just flick off.... Alternate between the brush being on the material side flicking dross off and away from the work, and the opposite side flicking the dross back across the work. With a very light touch I can remove all but the most stubborn dross, over 97% comes off in seconds. If it doesn't, then there's something up with cut parameters!

Re: Dross Scraper
Nope. Like this picture. I have one like in the link for sale. Not enough power. Tilt it at an angle to remove slag and weld splatter. Sharpen the chisel occasionally and add a couple drops of oil when using.

Re: Dross Scraper
I usually just use a heavier putty knife or just tap the edge with a chisel and the dross just pops off.

Re: Dross Scraper
I typically use a heavy masonry chisel. It will push the dross right off. I also have a Ingersol Rand needle scaler. I works amazingly well but I'm lazy and typically reach for the chisel.

Re: Dross Scraper
Same here using the chisel 75% of the time, it does need to be kept sharp though.
For likes of a tree of life the wire brush on the grinder whips it off quite well used at the right angle.

Re: Dross Scraper
Cutting at the correct power level, speed and height will make dross removal a simple task. The tool that SeanP pictured looks like a 3" wide masonry chisel.....perfect tool for knocking off the dross. If you have to resort to an air powered tool to remove dross....then you are doing something terribly wrong! Too much dross!

Re: Dross Scraper
I also use a wide chisel and the weight does the work for you. Just make sure no nicks develop in the sharp edge because it can scratch the metal with the sliding action.

Re: Dross Scraper
That is a true statement. I have not used the scaler since moving from the Esab to the Hypertherm system. I think my chisel is 1" wide.jimcolt wrote:Cutting at the correct power level, speed and height will make dross removal a simple task.

Re: Dross Scraper
I made a set of chisels and heat treated the edges. They work great but the air chipper is so much easier on your body and is faster. Time is $! Think ergonomics. I wasn't forced to use it just thought it made sense.

Re: Dross Scraper
Jim, is there a difference in dross removal if done right after cutting vs. a day or so later. It "seems" to make a difference.jimcolt wrote:Cutting at the correct power level, speed and height will make dross removal a simple task.

I may be wrong, but some items I took off the table and "started" cleaning immediately were really easy. The same pieces a few days later, it appeared to be harder to remove the dross.
Maybe just tired . . .

Re: Dross Scraper
Having used an air hammer (what that gun is in the pic) a LOT. I would have to say that tool probably contributed more to my arthritis than anything else! Mechanics gloves didn't even exist at the time much less impact gloves, I wear my Miller Metalworker's gloves most of the time these days. We used the brown Jersey Gloves back then. I haven't used an air hammer in probably 20 years for anything... Hope I never do again, The things just cause me more discomfort than time saved POS. Knocking off Dross is not that big of a deal, adjust your power and speed to minimize it.CNCCAJUN wrote:I am thinking the same . . . arthritis with age makes air tools look like a deal . . . sort of like my mowing philosophy, I have less than 1/2 acre & use a SCAG 48 Tiger Cat Commercial Mower . . . don't need it, but I am done in less than 20 minutes . .DXF wrote:I made a set of chisels and heat treated the edges.

Using the chisel hand held and just sliding it along letting the weight of the tool do the work is vastly superior to the air hammer!

Re: Dross Scraper
I do know that the mason's chisel works very well, it works even better if you eliminate the double beveled edge.
Just grind the edge flat. Now you have two edges to scrape with, easier to re-establish the edge & you can now hold it at lower angle. I tried both ways & the flat edge is easier on your wrist also.

Re: Dross Scraper
I use this carbide scraper from Lisle. I've had it almost a year and use it on everything that comes off the table and it still looks new. I'm willing to bet the handle wears out before the carbide! lol
