Evening all. I have recently acquired a few old bit and bobs which I'm sorting through.

I've got a bunch of these:

I can't find anything like them - probably because I don't know what I'm looking for. What are they please? :?:

I've got a couple of oilstones - does anyone have any idea what sort of grit level this is likely to be?

What does it mean by 'combination' stone? As far as I can see there's no division in the middle that would indicate different grades per side so I think it's all the same. From what I can make out, it seems to be a fairly decent one.

I've also got this one that someone's carefully made a nice box for. It feels completely smooth to the touch so must be a high grit level. It's not flat, unfortunately.

I assume it must be a decent stone for someone to take the trouble to make the box for it, and it's seen a lot of use. Can it (does it need to) be restored?

I've got an old brace and a load of bits of various descriptions. The brace is no use at the moment as the jaws are knackered.

Is there anywhere that supplies replacement jaws please? They're the alligator type with the captive spring.

Picture 1 is a group of cutting irons for a wooden plough plane - thing for making grooves. You seem to have a fair range of sizes.

Wooden ploughs were sometimes sold with a set of eight irons, numbered 1 to 8. They started at 1/8" (nominal - they were ground by hand and rarely dead-nuts to size, but usually pretty close) which was a number 1 iron, and went up in 1/16" increments, so 3/16" was a 2, 1/4" was a 3, and so on up to 9/16" which was number 8. The number is usually stamped at the top end.

If you look very carefully at the sharp end, you may see a slight difference in colour between the steel on the top face of the iron, and the wrought iron that makes up the bulk of each cutter - so-called 'lamination'. That was quite common on older edge tools - forge welding a small piece of expensive tool steel to make the cutting edge to a larger chunk of much cheaper (and easier to forge) wrought iron for the bulk.

The biggest problem when sourcing a wooden plough is not finding the plane - they're quite common and often not very expensive - it's finding a set of cutting irons. Consequently, you've had the big problem solved already. All you need now is a decent plough plane!

I think your stone is probably better than the one that was in the box. So possibly a fine man made oilstone.

I agree with your assumption. It's a natural stone, not a man made one.
You could wipe the dirt off the box, but remember that the stone was as it currently is when its former owner last used it. You are a beginner, he probably wasn't.

Not that I know of. But finding a better brace is easier than finding good bits in useful sizes.

Pictures 2 and 3 are a pair of oilstones. The Carborundum Aloxite is a coarse/fine-ish (you'll feel which side is which if you rub a finger over it), the one in the wooden box looks like a natural stone, and if it feels smooth, it's for a final polish to refine an edge to that next level of sharpness.

There are some real sharpening stone geeks about, and no doubt one will be along shortly with chapter and verse. I'll just say that with a bit of a clean-up, those two stones used with some thin oil (3-in-1, baby oil or mineral oil, which are all pretty much the same thing) you have everything you need to hone and polish straight-edged tools in those two stones. Add a grinder of some sort, and you're all set!

The stone looks like a very fine washita type stone from the united states, but it's hard to tell for sure. They all feel really smooth when they're loaded.

The rest of the stuff that you have is yard sale goods. the irons are interesting, but their tapers will all be different and that makes them not particularly useful for someone wanting to stuff them into a plow plane.

The stone has the potential to be a dandy stone for actual use (the natural one), but not to be confused with lots of economic value (perhaps 30 - 40 pounds). Worth your while to have, though.

Not the original half-box? :lol:

How should I store it? Presumably left partly-exposed in half a box isn't ideal.

I have seen combo stones where the division is nearly impossible to see, although generally you can see at least some differentiation (in colour if not in grit size, sometimes the two sides are not that far apart in grit number).

If the stone isn't what the box indicates you're never going to know for sure what it is, so for the potential user it's simply a case of trying it and seeing how it works.

Aloxite was Carborundum's equivalent of the India stones from Norton by the way. The original Carborundum stones were the equivalent of Norton's Crystolon.

Wrap it in newspaper for now. Or put it in a ziplock back if you like.

Very nice box! Could do with a good clean but that's a better-than-average example.

mrbadexample wrote:Can it (does it need to) be restored?

Thorny issue I'm afraid, be prepared.

Can it? Yes. Does it need to be? That's a depends.

What the stone will be used for informs what should be done to it with some people not minding dished stones, although the nature and amount of the dishing is important. Personally I think it's useless as an anything-and-everything hone as it is and needs to be flattened. (Cue tons of pointless circular argument if a certain party sees this thread.)

But the first thing you should do is check the underside – if you can get it out of the case! – to see if this is already flat. If so you can just use that side.

If you go ahead with flattening this process will clean the surface while you're at it, although many prefer to clean their stones in advance of any surfacing work so they can get a good look at the natural features.

This may sound bonkers but the best place to source replacment jaws may be inside the chuck of another brace. And in the UK this doesn't mean you have to overpay for them!

Of course it could be the case that you might as well use the other brace if you've gotten it, unless you deliberately bought a basket case that still had good jaws. This isn't unheard of as they can be protected by grease while the bare exterior decays and decays over many years; I've pulled nearly pristine jaws from braces that were absolutely solid with rust!

How bad are the existing jaws?

It is and it does - can't pick it up without getting filthy. I wasn't planning on doing anything other than making what I've got useable where possible, so am not looking to do anything other than clean it - BLO and steel wool? :?:

Hmmm...it was glued in once, rough side down, apparently. :lol:

I've been playing with the other one to sharpen some chisels and plane blades. Considering I don't know what I'm doing, the Aloxite (or whatever it is) seems to be fairly user friendly. But how can I hone a plane iron on a wonky stone? Or a chisel, for that matter? :shock:

That's what I was hoping for - enough to do what I need without spending owt. I have a bench grinder. Ex-boot fair, guardless, probably lethal. :roll:

Along with these oddments I've got a few firmer chisels, a few bevel-edged chisels, a couple of heavy mortise chisels, some gouges of various sizes and a couple of saws. Most appear to have been abused a little bit as a minimum. They have lumps out of handles and edges. What I'm looking to do is to put things back to a decent working condition but not much more than that. Cleaned, sharpened, problems addressed but with most of the original character remaining.

I can't see me getting much use out of the plough plane irons.

Older irregular stones were often bedded so that they'd sit still and firmly in their honing box.

Once stones were cut in regular shapes one after the other, they could put them in manufactured boxes (or you could make a flat-bottomed box) and not have to do that.

From what I've seen, the users didn't spare the rod when it came to gluing them in.
