Blunt Chisel?

[bwringer]

As with any pre-medieval pursuit, metalworking seems to have a strange language of its own. I think all I need is the correct term for what I want, and Google and I can take it from there.

Anyway, what I'd like to find is a blunt chisel, or a set of them.

Imagine a large cold chisel with a rounded nose (like maybe a 1/4" radius) instead of a sharp edge. Yes, you could whomp up something close to this in a few minutes with a spare chisel and a grinding wheel.

I want a nice new one. Something I can place exactly where I want it and then whack with a hammer.

What's it called?

I think what you're after is a half-round chisel.. I use them for rolling edges and the like

A Bolster?

edit: ignore that comment, lol

1/4" radius is a big radius. I would grind down an old cold chisel then weld some bar stock onto it.

Look at masonry chisels.

So you want a chisel that has an end with a dull shape similar to the edge of a larger cross pein hammer, is that right?

You're probably looking for a chasing punch like what is used in Jewelry making, but in a larger size appropriate for blacksmithing.

Pieh Tool Company has something that sounds like what you're looking for.

Exactly. If my aim were perfect, then I could use a cross pein hammer. I'd like more precision in my thwacking.


You just know this thing is out there with some stupid name left over from the days of King Arthur.

"Knave! Give the __________ unto mine hand forthwith! We must make haste to repair the armor of Sir Featheringstoneshaugh ere the morn's battle."

What about driving a cross pein with a dead blow?

I had in mind something bigger (although I don't have a specific application in mind at the moment), but that's the right idea.

It almost seems like this is the sort of thing one would be expected to make as needed.

About the closest thing I can think of right off the top of my head would be something like a set of T-dollies for metal shaping. You usually clamp them into a vise, but I don't see why you couldn't use them upside down like a cold chisel to make indentations in metal instead. The picture is an Eastwood set, and the smallest diameter is 1/2" (1/4" radius), and the largest is 1-1/4".

I apologize but I've got to ask. Are you a metalworker without a welder? This is a round piece of metal welded to a flat piece of metal. Why buy it instead of make it?

I don't know if you are talking to me or the OP, but I agree with you on some levels. In it's most simple form it is just a round steel rod welded to some bar stock and shaped a little bit. The one benefit of the pre-made t-dollies is that they are usually heat treated and hardened which is something the average person with a welder can't do. Depending on what you need it for that might not matter though.

The only reason I mentioned them is because the OP said he wanted to buy something already made, not make it himself. He also didn't want to use a grinder to shape the end of a cold chisel to work, so these t-dollies were all I could think of off the top of my head.

Jeremy, I was talking to the OP. Good job on finding those because I think those are about what he is looking for. The OP didn't say what he wants to use them on other than he's looking for a radius that's a little too big to get by just rounding over an old cold chisel. I wasn't trying to knock the OP down any just wondering why a metalwork would shy away from making such a simple tool and would rather buy it.

 

[bwringer]

I was thinking of buying this mystery tool because it would be very difficult to grind a chisel to a nice smooth radius.

Those T-dollies look interesting, but is the "handle" really made for striking?

Sure, I suppose I could weld a chunk of round bar to some sort of handle and solve that problem, but I'd still be left with my original question: what the heck do I call the thing?

If "thwacker" isn't taken, maybe I'll use that. Or perhaps "thwackee" would be more accurate.

What about a bearing race punch?

What you're looking for is known as a 'fuller' in the blacksmithing community. They can be made in a variety of sizes/ radiuses, most being forged and ground out of a straightened coil spring by the smith that needs it. If you want to buy one/ a set, check out BlacksmithDepot.com.

Get old dull chisels at the flea markets for a quarter each and form them on a grinder. They don't really need to be heat treated for working tin.

A bodyman friend has a 5 gallon bucket full of things that he uses to whack on tin with, To him its bread and butter tools and to an unknowing eye its a bucket of scrap metals.

If there are any heavy equiptment shops in the area those yellow machines are a goldmine of hardened steel plns and other useful forms. Worn out teeth for the rippers make great dollies.
