Quangsheng Router Plane

I had a slightly spooky experience earlier this year when I found myself reading my own words almost verbatim from someone else’s hand. I don’t know who sent Paul Sellers one of the prototype router planes to review, but he raised all of the issues I had asked the factory to rectify before we went ahead with the product.

On reflection it’s actually quite reassuring, Paul is hugely experienced and knows exactly what he’s looking for in a hand tool, so it is good that we concurred on the things that needed addressing. I’m just not used to that part of the process happening in public, but hey why not!

If you didn’t catch Paul’s review it’s here: A Router Too Young To Shave!!!

Anyhow, here’s where we are up to now:

Second Prototype

The problem with the locking screw obscuring the cutter has been resolved with a larger, flatter screw with an undercut head that affords the user a proper view of the cutting edge.

Because the depth of cut is altered frequently in use, it needs to be possible to tighten and loosen the screw with fingers rather than a screwdriver – the bigger diameter head makes this possible.

The users view on the first prototype (shown below) wasn't so good:

Next Issue: The missing main cutter!

As Paul rightly said, the vast majority of a router plane’s work is done with a broad square edged cutter, which was notable by its absence on the first prototype.

On the bright side, this gave me a chance to influence the design a bit, so the new main cutter has a nominal width of 12mm with a slight taper so it cleans right into the corner without binding.

There is more relief angle underneath and both sides of the stem have flats, so it will default to square in either orientation without needing to be set.

The icing on the cake was to add full depth side bevels so it can be used in sliding or half blind dovetails - very handy.

 

The bottom of this trench came out glass smooth straight off the cutter with a fairly heavy 1/2mm setting across the grain, I haven’t honed the blade at all – just popped it straight in and used it.

Working on narrow stock

The remaining cutters have been left with a flat on one face of the stem and round on the other. This allows them to be set at an angle so the plane can be skewed when working on very narrow material, or perhaps more likely, to span a stopped housing close to an edge.

There is a fourth cutter with a broad V-point but I can't for the life of me remember where I've put it, maybe the next thing I should make is a nice box to keep it all together. 

There are a few other new treats arriving in the same shipment, more on those shortly.

Availability:

The router planes have just (1st December) landed in the UK so they will be available to order in the next few days.

The main cutters didn’t make the shipment, so they will be arriving by courier in two weeks time, these will be posted out free of charge to anyone who has already bought a router and included with the plane thereafter. 

Price:

The router plane costs £59.50 inc VAT

I will post a link here as soon as the listing is live.

Cheers,

In search of an extraordinary man, J Munro, Cabinetmaker & Minister

I recently acquired a beautifully proportioned Scottish pattern infill smoothing plane at a David Stanley auction. I wasn't intending to buy it, but when the lot came up my hand seemed to develop a life of its own, at one stage I even tried to bid against myself - much to the amusement of the auctioneer and my fellow bidders. This one chose me - not the other way around.

The body is gunmetal with a steel sole sweated on, overstuffed with mahogany, and stamped on both infills with the name J Munro. Planes of this type would originally have been sold as a body and the infills completed by the craftsman. The pleasing proportions and elegant curves of the infills on this one are perfect to my eye, full and well balanced it just looks 'right'.

The stamps on the rear infill are unusual, tight against the sides of the tote such that they would have been very difficult to strike squarely after the tote (handle) was fitted. This and the fact that there are no other names on it, suggest that this is the mark of the man who originally stuffed the plane.

Out of interest I googled 'J Munro cabinetmaker' and scrolling past the references for J Munro-Bell (who wrote the book on Thomas Sheraton) came across a John Munro junior in the records of cases decided by the Scottish Supreme Court 7th July 1837. The date is about right for this type of plane, so we may be on the right track, but how the blue blazes did a simple dispute over an indenture of apprenticeship end up getting all the way to the supreme court?

19th century Scottish legalese is far from easy reading, but from what I can ascertain, our man was apprenticed to John Clark of Inverness. Munro left before his apprenticeship was complete and set up on his own and both he and his father were duly sued by Clark for 'horning' or reneiging on the terms of his indenture. The Munro's countered that Mr Clark had "deserted his work without leaving any one to teach his apprentices their trade, as he was bound to do" furthermore they asserted that that Clark "repeatedly assaulted and ill used" Munro Jnr and that he did not provide his apprentices with proper board.

Clark pursued the Munro's all the way to the supreme court, whose four judges unanimously upheld the decision of the Lord Ordinary in favour of the Munro's, that they had caution (pronounced Kayshun, meaning protection) in the terms of the original indenture of apprenticeship.

I also found a later reference to a Scottish cabinetmaker named John Munro in a history of Clan MacIvor, who having trained as a cabinetmaker in Scotland, emigrated to New York and continued his trade there. On a visit back to Scotland he found God and was encouraged by friends to join the ministry, he struggled with the decision but...

"He went back to New York intending to work at his trade; but, as he told it himself, he never unpacked his tools, but returned to Scotland, entered college and began preparing for the ministry."

After a spell in Edinburgh where he met his wife to be, a homeopath, Munro emigrated to Nova Scotia in 1848, was instrumental in the construction of no less than four churches, Rev John Munro and his wife lie alongside each other beside one of the churches that he founded and ministered in for 28 years before his death in 1877.

Whether these two tales are of the same man, and whether it is the same man who made such a beautiful job of stuffing this infill plane I will probably never know. But the thought that it might have been made and owned by a gentle and principled man who wasn't afraid to stand up for his beliefs makes it that bit more special to me.

If anyone has any further information about John Munro I would be very glad to receive it.

The Humble Gimlet

Gimlet is a lovely word, it comes from the French 'guinbelet' and refers to a small, very simple type of hand drill that was ubiquitous up until the invention of the lip and spur. 

The French got the word from the Dutch 'Wimmel' meaning auger, which despite the best civilising efforts of 'le bourgoise' also survived intact in colloquial French and was brought over by the invading Normans to become 'Wimble' - a common generic term in old English for any type of drill.

It is appropriate then, that our new 7 piece sets of crisp, sharp classically formed gimlets are made by a small company in France. I had used old ones before and they still did a reasonable job, but the difference when you try one that is new and sharp is nothing short of remarkable.

The gimlet has survived, virtually unaltered for a thousand years, thanks to its usefulness for preparing fixing holes at the ends of boards. Having planed your boards true, the last thing you want to do is split them near the ends when you drive a nail or screw. In good air dried timber a gimlet will cut a beautifully formed hole anything up to one and a half times its own diameter from the end of a board. The conical shape of the hole allows screws to engage fully, or if you prefer you can clamp on a sacrificial backing board and carry on drilling for a clean, parallel sided, through hole.

I don't expect these to catch on with the power tool crowd, but if your heart is set on working unplugged they are something of a necessity. 

Rice and Chips - The new Fugaku range of saws from Gyokucho

In the 1940's Japanese knifemakers combined the virtues of European and Japanese knives to produce the santoku - a design classic that has now become ubiquitous in kitchens throughout the world.

Gyokucho, the company that invented and perfected the replaceable blade Japanese saw in the 1970's, are fishing for a little bit of that same east-meets-west magic with their new range of Fugaku folding saws, and I believe they have hit upon something rather special.

Lacquered quartersawn beech has been the preferred handle material for English backsaws for centuries. The way that the material is cut from the log maximises its dimensional stability and, when the light catches it just right, also displays the flower of the timber beautifully in the faces of the finished piece. This harmonious combination of function and appearance is just the sort of thing that the Japanese appreciate and it sits naturally with their own experience of high quality lacquered finishes.

Another functional aspect of western backsaws is the clever use of weight, a carefully proportioned spine engages the teeth perfectly for maximum cutting efficiency and the sawyer can use their discretion as to how much of the saws weight they either support or allow the wood to bear. It's a bit like driving a car with cruise control stuck at 55 and controlling everything with the brakes. Master this and you can start smoothly and stop at a line.

Rather than adding weight simply for its own sake, Gyokucho have used it to over-engineer a beautifully smooth folding mechanism and a folded spine made from a thicker steel pressing than that used on their traditional Japanese saws. This extra weight gives the saws a more pronounced sense of feeding the power on or holding it back, as well as the technique common to both cultures of using sharper strokes to cut faster, or softer ones to cut with more control.

The blade geometry and toothing are all Japanese; for saws that are used horizontally the logical arguments for a pull stroke and a thin blade working in tension are unassailable. They have however, chosen blade designs from the existing Gyokucho range that are functionally closest to the western trinity of dovetail saw, carcase saw and panel saw.

At the moment woodworkers are polarised by lack of choice into a preference for either western or Japanese saws. Whether there is also a group who prefer saws that respectfully draw upon both traditions, only time will tell.

Marc Fish Dovetails

The other day I shared a post from Marc Fish advertising his upcoming weekend dovetailing course at Robinson House Studio in West Sussex. Another good friend, Rob Stoakley, left a comment questioning whether it would be possible to teach a joint like the one shown in the photo on a weekend course?

I should point out that this joint isn't the actual content of the course, that starts with a basic right angle through DT, progresses to half blind followed by a look at the more complex stuff. Having said that, it was my contention that this joint could be taught in a weekend. Once you have grasped the basic principles of hand cut dovetails, it isn't a massive leap to introducing a few cheeky curves and non-90 angles. Before you know it you can be confidently exploring a whole world of creative possibilities that are only accessible with hand tools and the same core techniques.

As you might expect the gauntlet was duly laid down and picked up, so here's a brief summary of the method I used to make a mock up of the dovetail joint from Marc's award winning desk L'Orchidée.

I used lime and mahogany, both relatively soft timbers, dressed square and true and then cut the end of the lime at an angle to replicate the pointed corner on the original.

My dovetail saw was a bit shallow in the blade for the longest edges, so I had to 'make do' with a 14" sash saw from Bad Axe. It is a testament to the smoothness of this tool that by using a very light touch it was still able to cope with the perilously thin mahogany, leaving just a whisper to clean up with a sharp thin bladed chisel.

Tails done, I transferred the layout to the front piece with a marking knife and carefully pared out the bulk of the waste to create a corresponding negative space. Fishtail skews are an absolute godsend for the job of tidying up the corners.

With the joint itself cut, it was on to carving and shaping the front. By defining edges first and then sneaking up on them from the middle it is possible to get complex curves pretty close by eye and then tidy up with sanding or scraping.

A drop of glue, a tap with a mallet to bring it together, and the joint is done.

Not as crisp and tight as Marc's joinery by a long chalk, but as a practice piece it was fun to make and demonstrates that with basic hand tool skills, common sense and a little bit of practice, you can take on more complex and creative joinery.
