A wood chisel has a narrow angle which leads to a thin and delicate blade. It is not robust enough to hold up to cutting steel. A cape chisel would be the correct tool for the job.Will a wood chisel that is hardened be used as a cold chisel since it has a flat under unlike a cold chisel having bevel angle at the edge
This kind if chisel?I once chiseled a 1" square hardy hole in a stake plate. It took about 3 months. It can be done, but there are few resources on the Internet telling how to do it. It seems that in the old days, most chiseling ("chipping") was done on cast iron, which was substantially softer than the steel you are probably trying to use. From what I read, it is important to hit the correct angle. Too steep, and the chisel digs in. Too shallow and it glances off, and you make no progress. Try to keep the chip going, and keep it small and thin. Sharpen the chisel as soon as it gets dull, otherwise you are wasting time dinging metal. Also, if you are hitting the chisel hard enough, it is going to produce a lot of noise. Unless you can control the noise, it will make neighbors mad. Hearing protection is a must. Unless the slot is small, I would recommend doing it hot, or making a tiny belt sander that uses 1/2" belts. This will be a lot easier. This kind of hammering can lead to repetitive motion injuries. Do not do it in long stretches, else you will become incapacitated for weeks. Do a little every now and then, and it will give you plenty of time to think about it. After a few weeks of pounding, you will want to check out an Alec Steele video and do it hot.
A wood chisel is made for cutting wood. It will be destroyed trying to use it to make significant cuts in steel. The very hard and thin metal and shallow included angles on a wood chisel are going to crumble in use. The handle is not intended for the heavy blows needed to cut steel. You do not need to believe us, Koi, get one and give it a try. Let us know how it works out.Will a cold chisel make a cleaner cut or a wood chisel assuming they have the same hardness to cut steel but with the difference of the shape ending with different result.
Can I make a cold chisel to have a flat under until where my hands grip. Will that improve the cut.I'm assuming it will focus all the hammering force in the same direction I hit unlike a commercial made Cold chisel.A wood chisel is made for cutting wood.

I have work on it for some time but makes me feel frustrated.The work just doesnt turn out as I expect but I find the file easier to use and things always turns out to be 99% what u expect it to be though there's just shape and profile you can't do with a file like putting a square hole or a square at the side of a piece of steelKoi, use the cold chisel. The wood chisel's edge will break if you use it on steel. But maybe you should try it. I did. Best to do it with a cheap garage sale one, since you will ruin it. Wear safety glasses. You can often find cold chisel suitable for your use for a dollar or less at a garage sale. Sharpen several, and feel how they wear. How long have you actually been working on the slot (as opposed to planning, discussing and shopping)?
That's what happened to me chip snaps of even before it gets an inchI made a project of cutting a v-slot in a tooling plate using hand tools. No, it is not finished yet, but it is coming along surprisingly well given how badly it all started out.
I started the slot with a hacksaw, then used a cape chisel to widen it, then used square files to form the V. The chisel did not work well; chips would snap off before they even got to an inch long. The steel plate is some of that 1/4" mystery stuff they sell at the hardware store, and is much harder than I expected it to be.
You might try using a file or hacksaw to score the line for the slot, as that will break through the skin of the metal which may be hard. Also, clamp some pieces of wood to either side, making a guide about the width of the chisel. I didn't do this, and marked up the tooling plate something ugly.
I haven't seen any soid advice on the angle for the chisel. It's always "too large an angle from the surface and the chisel won't cut; too small an angle and the chisel will get dull fast". Maybe hone the chisel on a stone and try a smaller angle?
EDIT: This guy appears to be using a 45 degree angle.
I may have not been hitting the chisel hard enough when at a lower angle. My nearest neighbors are a quarter mile away through the woods, so maybe I'll whack the thing hard enough to make the complainAlso, if you are hitting the chisel hard enough, it is going to produce a lot of noise. Unless you can control the noise, it will make neighbors mad.

For now I haven't come across any cape chisel but a cold one is dirt common though I can make one by building a forge but for now I think should focus on getting a round column mill drill. hasta la Vista baby hand machining.One of the old books I was reading mentioned using cutting oil when chiseling steel. Maybe I'll give that a go when I'm in the shop this afternoon, try out some good sulfurized cutting oil on some scrap.

Not sure where you would find them in Malaysia but there should be a regional manufacturer making an equivalent.
Thanks that's a lotI have a collection of cold chisels from little tiny ones to great big ones. There are many different and specialised chisels for metal and and used well the cut metal fast and accurately. Cutting a slot is easiest in a vice after drilling a few holes. A wood chisel is only good on metal for cleaning off gasket material.
