Thanks for posting that. And, how did you get the link to start at that point? :D

It seems to me that the thinner a piece of metal is the more likely it is to vibrate under the same conditions as something thicker. I’m guessing the real reason old plane irons were so thin is because tool steel was more expensive years ago than it is today. It’s certainly seems much easier to make given the stock prices I’ve seen? The Japanese tool makers seem to have the right idea. Back a thin piece of high carbon steel with a thick piece of Iron? There are some contrarians out there but I’ve not seen anything to convince me. Just because you can make something work well doesn’t necessarily mean it’s a good design, or indeed, can’t be improved. I’m sure the Ford Model T was very good in its day but thankfully car design didn’t rest there on its laurels.

I’m putting a potential purchase on the back burner as I’m wondering how difficult it would be for me to make my own plane given I have some machine tools. I’d probably need to buy an Iron though if it’s to be successful. Don’t watch this space, it could take me some time! :lol:

It's not only the Japanese that do that. All of the older English irons you'll see in old wooden planes will be of laminated steel construction, a high-carbon steel forge-welded to a low-carbon steel backer, even Stanley and Record were using laminated irons up until about the 50s when it became cheaper to make the whole iron out of tool steel. You'll see it if you sharpen a Record "Best Crucible Cast" iron (the older ones with the square shoulders) up to a high polish, on the bevel you will just about make out the line between the harder high-carbon steel and the softer low-carbon.

Here's an image I've stolen off the web that came from a Stanley advertorial:

Sometimes I wonder whether that's where the secondary bevel originated from, use a coarser stone to cut through the softer backing, then use a secondary bevel on the harder steel as so not to contaminate your fine stone with soft steel powder.

Fair enough but from which source ? I sometimes think that these 'ideas' develop a life of their own.


Okay - built up over a period of time and based on a mixture of what I have heard from people I would respectfully consider more learned that me and my own experience.

As I recollect when I did a weekend’s fettling course (c. 10 yrs ago) with Chris Tribe it was first discussed. It was then reinforced by David Savage (and several of his makers) when I did a course at his workshop. I swapped the iron in my Record No6 as a result and immediately got less chatter. It’s entirely possible I did something else at the same time without noticing (got better at sharpening?) which made a difference but on balance I think there is a logic to a thicker iron being less prone to vibration/chatter. Other things though such as a a better and well fitting chip breaker, improving the seating of the face of the frog or a better edge will also help.

Apologies if you feel I have implied that a thicker blade is a silver bullet Roger - to put it more accurately I believe it’s one of a number of factors that reduce vibration/chatter and as HRH may put it opinions will differ!

I haven't the least doubt that you're right, Robert. But chatter with a No. 6? I've never heard of that happening.

:lol: Mike - my son tells a story of the afternoon he learned new swear words while watching me try to get said plane to work as it should do. FWIW full marks to Chris Tribe who showed me how to sort it with the most important lesson being to experiment and find a way of sharpening that works for you and don’t give a monkeys about what the purists say!

Chatter is a really odd thing, sometimes. I have 3 spokeshaves which are indistinguishable from each other. They are all but identical. But I can guarantee that at least one of them will chatter on any given piece of work. There's no good reason why one should do it and not the others, but it happens. Nothing wrong with the spokeshave, really, because like as not it will work perfectly on the next piece.

I've had similar experiences.

There's bound to be a complete physical explanation, probably at the level of quantum mechanics but FWIW I reckon that in such cases it could be down to the ergonomics of the handles/grips. Maybe there's a fractional difference between them in different tools but the woodworker's grip stays the same and so maybe this results in a small difference in the attitude of the tool to the wood. On the other hand, I could be simply overthinking it ...

You need some low angle wooden ones, or a Ron Hock blade and make your own.
Preston spokeshaves are far less chattery than the Stanley/Record ones.

A good bed filling will help most spokeshaves perform better.

The amount of chattering you get when using wooden spokeshaves from my experience seems to be very much dependant on the density of the wooden handle and the blade it has been coupled to. I have a few pairs wooden shaves in S M & L sizes for flat bottom and just a single for rounded sole in each size. I have found that the round soled shave don't seem to have a chatter problem - ever. However, when I first got the flats a couple of them (one large, in particular) was very prone to it. So much so it prompted me to get a second set of shaves and I then played about and swapped the irons over. Voila, no more chatter. I did investigate a bit and found the chattering combination to be a few grams lighter that the non. Once the blades were swapped there was just a 1g difference between them.

Not got round to trying it but have often thought that perhaps giving the wooden handles a few weeks of immersion in some BLO etc would help to mitigate or eliminate the density problem by changing the resonance of the wood

Good video Dan.

All this stuff now largely superseded by hand held electric planes like the little Festool though. :eusa-shhh:

I saw that video a while back so I won’t watch it again but didn’t he say the whole blade on the Stanley is tool steel unlike the picture posted earlier of the laminated blade?

It must have been another one I was thinking of as my history suggests I watched it yesterday or the day before. Either way I watched it before you posted the link.

Of the two suppositions you’ve posted which one do you think is most likely? :eusa-think:

He did, and went on to say that you could use the blade right down to the end, and he described why it was an innovation at the time. He even shows some advertising from the launch era.
He likes hock blades as do several folks here, whose opinion I trust.
I quite like his style, not too enamoured about most stuff on y tube but might check out some of his other stuff.

Yes, you're right, it's been up for a couple of days, my mistake! :oops:

Woodster wrote:Of the two suppositions you’ve posted which one do you think is most likely? :eusa-think:


A supposition in regards to iron construction or iron thickness? I posted the video as more of a point about iron thickness but I can see how you can get the iron construction query from it so I'll answer both anyway.

I re-watched the video and Rex does indeed say that the iron is made completely of high-carbon steel, so I've actually gone out of my way to research this a bit further because I was curious as he's not usually wrong and quite well read-up on whatever subject he's talking about and interestingly I've found out that earlier irons made by Stanley were indeed solid tool-steel and they actually started laminating the irons in the 1920s as a cost-cutting measure and then went back to solid tool steel in the 1950s.

Regarding iron thickness, it's obvious that a thicker iron is going to deal with chatter and other issues better than a thin iron, but it is the wrong solution for the root problem which is a poorly set up plane. If the plane is set correctly with a thin iron that is properly supported by the frog of the plane it should work as intended just as well as one with a thicker iron. If the thin iron is supported properly and clamped in place solidly it becomes homogenous with the frog and in effect, theoretically turns it into a thicker iron by virtue of that support behind the cutting edge, if there's a shaving trapped between the blade and frog or if the frog is twisted you are going to get chatter, a thicker iron will help remedy this but it's solving the symptoms and not the problem.

I rather enjoy his videos, even as a machine man I find them worth watching as they're not over-the-top and are quite informative despite being himself being a self-proclaimed amateur woodworker. Just an easy watch.

I’ve seen a few of his videos but I admit I don’t find him as convincing as some other YouTubers. I happened to look at the comments on that particular video and he let himself down badly with some very childish comments.
