New handles for Narex 8116 Cabinetmaker's Chisels

Narex 8116 Cabinetmakers Chisels

We really, really like Narex's 8116 Cabinetmaker's Chisels, superb steel, fine accurate machining, great profile and a great price, but I couldn't help feeling that the handles would be so much better if they were just a fraction smaller on the smaller sizes. We mentioned it to the management and before you could say "To bylo rychlé!" a sample of the new handle was resting comfortably in my hand!

The first shipment of the new ones arrived today, so we will be dispatching them with the smaller handles as standard when our new website launches (fingers crossed) on December 5th.

In the meantime, please use the shipping comments box to add 'smaller handles please' or 'larger handles please' and we will send you the appropriate chisels.

Lateral Thinking !

Quangsheng No. 62 Low Angle Jack Plane

One of the minor points levelled against bevel up planes is that their capacity for lateral adjustment is limited because the cutting iron is nestled down between the side wings.

Here's a quick and easy way to give your bevel up plane as much lateral adjustment as a bevel down one.

mark the area to be adjusted

First mark up the sides of the iron with a permanent marker so that you can monitor your progress.

grind a small amount from the sides of the blade

Next carefully hold the blade over a linisher (a well secured upturned belt sander will do if you don't have one). Allow the shoulder of the blade to make contact first and then gently lower the blade until the sparks start just behind your thumb. You are aiming for this:

decrease the width of the blade

A nice even taper running from about halfway up the iron to the shoulder, taking about 1.5mm to 2mm out of the width on each side at the shoulder.

The result:

lateral adjustment improvement

About twice as much adjustment as you had with the parallel sided iron, and the front end remains parallel so it will still fit into a side clamping honing guide.

The Quangsheng iron I am using here is differentially hardened carbon steel (only hardened from the slot down so that the soft upper part dampens vibration). Air hardening steels are all or nothing, so if you try this with an A2 blade the whole thing will be hard and it may take a little longer to grind back.

Free Shipping Fortnight!

UPS delivery driver

...or you scratch my back and I'll scratch yours.

There are all manner of things that can go wrong with an order - computer says one shelf says nil, lost in the post, defects, niggles and other fluff to sort out. True, it is rare, but it would be churlish to pretend that it doesn't happen occasionally.

We work incredibly hard to ensure that these problems never get as far as the customer, but if there is one thing that makes complete and total customer satisfaction easier to achieve, it is time!

In order to sway the balance of time in our favour we are offering FREE shipping on all UK orders for the next two weeks (13 - 26 November) in the hope that we can persuade our regular customers to get their Christmas orders in nice and early. Just to spice things up a bit further we have waved our discounting wand over a selection of popular products and put them up on the Workshop Heaven homepage.

At the end of the day I don't want to spend Christmas day worrying about whether Mr Jones from Llandeilo received his Quangsheng No. 4 in time. I'd much rather be enjoying the way my carefully waterstone-sharpened carving knife will sever immaculate wafer thin slices of roast fore rib of beef with no downward pressure at all, or marvelling at the fact that my four year old son actually likes brussels sprouts! If you are prepared to indulge me this small favour I am more than happy to redress the balance with a bit of free shipping.

The Combination Square

many uses for a combination square

Invented in the United States in 1878 the combination square is a very versatile instrument indeed. I thought it might be fun to run through as many ways to use one as I can think of and then see if anyone can come up with any others.

As well as the obvious uses for marking lines square to or at 45 degrees to an edge, the combination square can also be used as a depth gauge:

A rudimentary marking gauge or panel gauge:

A protractor, dovetail marker or an extra sliding bevel if need be:

using a combination square as a protractor

A graduated centre finder for both establishing and measuring from the centres of round materials:

Or a mitre gauge:

A small level, (and because it's a square you also have a means of gauging for plumb):

using a combination square as a level

A greater level of accuracy can often be achieved by using the components independently.

The square head can be used as an internal 135 and 90 degree square:

using a combination square as an internal square

The centre finder as an external 90 degree square (note the cutout for the corner to rest in):

using a combination square as an external square

And the protractor head can be used as either a level or an inclinometer:

On a good one like this Starrett C435M-300 Metric Combination Set, the photo engraved hardened steel blade is accurate enough to use as a straight edge too:

using a combination square as a straight edge

In almost all cases a dedicated tool probably will do a better job (assuming that you are looking at a similar quality level). However, for a lot of woodworking tasks the level of accuracy you can achieve with a decent combination square is perfectly acceptable.

If budgetary restrictions are a consideration then you may be better off getting one good quality combination set than struggling with lower quality individual tools.

The sheer abundance of things that you can do with a decent combination square make it a wise investment for the beginner woodworker and it will always be a useful tool to grab whether you are working in or away from the workshop.

Spoon Karving Cnives

Ray Iles Carving Knives

Spoonerism - spoon carving knives - get it? Oh well never mind.

What you definitely should get is a set of these wonderful new spoon carving knives from Ray Iles. I've only had a brief play so far, but when it comes to a tool that you work so intimately with as a spoon carving knife, starry eyed love at first sight is a pretty good starting point.

Let's begin with the handles. Plain double turned beech ovals, but the belly is offset towards the rear, so it nestles under the middle and ring fingers before narrowing again for the little finger - hand shaped in other words. Towards the business end, the handle narrows in thickness to a slender lozenge cross section, making your index finger very 'aware' of the exact angle of the blade and able to alter it very precisely by squeezing or relaxing the grip.

Next the blades, hand forged O1, a material Ray has been using for most of his working life, tempered to RC59-61, hollow ground bevels, polished to a shaving sharp edge. I'm wondering whether I wouldn't be happier with a left bevel crook knife as I'd kinda prefer to use this beastie away from my body - maybe I'm just not used to it yet? If you are used to Moras the first thing you will notice is how much thicker the blades are (3mm). The whittling knife and the spoon knife have rounded backs so you can comfortably lay a thumb or fingertip on the back of the blade for very fine control. These two factors make a world of difference. I'm sitting here with a lap full of boxwood shavings, alternating between carving, typing, and watching in amazement as the best teaspoon I have ever carved appears before my eyes. It feels like I have swapped hands with Jon Mac!

Lastly the bit that normally gets forgotten - the tang. The balance on these knives is just beautiful. All of them balance, as they should, slightly forward of the centre of the palm. The barest fraction of weight bias toward the blade gives the necessary registration, but keeping it as small as possible keeps fatigue to a minimum so you can carve in comfort for longer. 'Full length tang' is often touted as a selling feature, but a 3/4 tang that has been balanced to give perfect weight distribution trumps it by a country mile in my book.

Ray Iles Carving Knives

Ray has been making tools from the moment he could pick up a hammer, he was one of the last people to be apprenticed to the little mesters of Sheffield and is possibly the only man alive to have apprenticed under them as a Smith, Grinder and Cutler - three apprenticeships - now that's deciding on a career. The jump from making things that are sharp on the end to making things that are sharp on the sides is quite a leap for a toolmaker, but I am so impressed with these that I have decided to stock almost his entire range on the new website.

Happy spoon carving!

Oops - nearly forgot, no photos - didn't happen.

Here's the finished spoon, could probably be improved with a bit of sanding but hopefully not too shabby for a first effort.

Work smarter, not harder.

Clifton plane iron

We have heard from a few people recently who have been trying to polish the backs of their plane irons and chisels to a mirror shine all over. This is a common enough misunderstanding and I have had to explain why it is unnecessary to some very experienced makers indeed. Most of them start out looking at me as if I have just come out of a tap and then the penny drops and they suddenly realise how many hours of unnecessary effort they have expended over the years and end up needing a cup of tea and a sit down.

The back of a chisel only needs to be polished for the first few millimetres under the cutting edge. This is achieved by hollowing the back by a couple of thou (no more) on coarse abrasives, preferably using a single line of contact to avoid the possibility of referencing off a bump. With the slight hollow achieved, you lay the blade flat on your finer honing abrasives and work just the underside of the cutting edge to a mirror finish. If you like to use the reflection in the back of the blade to gauge the geometry of your chopping cuts, then by all means carry on and polish the first 10mm. Zero to minus 2 thou is plenty flat enough for precision joinery so your chisel is still technically 'flat'.

The back of a plane iron is not a reference surface and only needs to be polished for the last millimetre. The back of a plane iron doesn't need to be flat, so elevating the other end of the blade by slipping a thin ruler / bit of paper / whatever underneath it when honing you can guarantee contact at the cutting edge.

The same goes for the irons of bevel up planes. The last couple of mm of the back is exposed in the mouth and doesn't register against anything, so there is absolutely no harm in using the Charlesworth ruler trick on them too.

If you find you are spending any more than ten minutes maximum preparing a new blade, there is a good chance that either the abrasives are inappropriate or the technique is not quite right. If you need some help, please get in touch and we will be happy to point you in the right direction.

Aside from saving a whole load of time and effort, the other advantage of minimising unnecessary polished surfaces on your tools is that polished steel is much more prone to pitting. A ground surface will tend to develop powdery surface rust all over, which if it does occur can be easily removed. The slightest imperfection in a polished surface (at a molecular level) will act like a sacrificial anode and fester away independently of the surrounding surface.

David Barron visits Workshop Heaven

David Barron visits Workshop Heaven

David Barron popped in today to drop off a copy of his new Dovetailing DVD and some Knew Concepts jewellers saws for me to try.

Man are these things light - but it's not just how light (120g vs 185g for our standard 5" jewellers saw) it's also how that weight is disributed. With a standard saw most of the weight is in the frame, resting on your index finger with 5" of mechanical advantage. With the Knew Concepts saw the majority of the weight is in the handle, so although it is only 1/3 lighter it actually feels about 2/3 lighter in the hand. They are also very stiff, so you don't get any compression of the blade on the forward stroke which is the biggest cause of blade fatigue.

Tension wise, they are about the same (although our standard adjustable jewellers sawframes do achieve a much higher tension than just about anything else on the market) with a heavier gauge skip blade installed what you really want to hear is a very short, high pitched 'plink', if it's still going 'pingggg' it's not tight enough.

The weight advantage makes the 8" version a no-brainer for me, the only disadvantage with a deep saw is the weight - take that away and you may as well just have one saw that will trim dovetails in a 16 inch wide board. Having said that there will be those who don't want to stretch the extra few quid or never use boards wider than 10" so we will probably end up stocking both sizes.

All in all a very nice piece of kit. Essential? No. Best on the market? Yes.

Cutting dovetails

Anyway, once I'd got over the whole 'David Barron - in my workshop - how cool is THAT!' thing, we had a really good chat about all sorts of tools and techniques. Here's a couple of top tips I picked up for freehand dovetailing.

Marking dovetails

Always engage the marking knife in the mark and then move the square to the knife. This is much more accurate than trying to align the square on your mark and then striking a line wherever it ended up.

Align your work

When securing your board for sawing, use your dovetail marker to set the angle of the board. This way your saw is working vertically (as it was intended to do) and gravity is assisting accuracy rather than hampering it. Cant the board the other way to make the cuts on the opposite side of the tails.

David Barron's Dovetailing DVD covers guided dovetailing - a foolproof way of achieving outstanding results. It is a well thought through technique, with guidance on how to make the necessary workshop aides and also has a very good aside on bench design and configuration. The quality of production and clarity of tuition are both outstanding and I am more than happy to recommend it.

A Grand Day Out!

Many thanks to all who came along to the Peter Sefton Furniture School open day on Saturday. It was a great day with plenty of demonstrations including Peter's live, public, review of the new Quangsheng 62 Low Angle Jack plane. I won't ruin the suspense for you, but as far as I'm aware this is the first time a new plane has been reviewed in front of a public audience, on some very challenging timber, by an independent expert suggested on a public forum, and then made available for members of the crowd to try out for themselves. The results will be published in Furniture and Cabinetmaking Magazine as well as on the various forums.

I was doing a bit of sharpening, showing some of the methods for honing trickier tools like cambered irons, skew chisels, fishtail chisels, shoulder plane irons and spokeshave irons with Richard Kell's honing guides. We also had some FAMAG drill bits available for inspection and copies of their new cataloge to hand out (if you'd like one just send us a message and we'll pop it in the post). I love the way people's eyes light up when they see their first FAMAG drills.

Also demonstrating were Tom, Simon and Sarah from the brand new dedicated Festool dealer Intelligent Workshop Tools. These guys really know their stuff and have some seriously nice kit. Bob Jones (Bob the polisher) was teaching the dark arts of grain filling, staining and polishing, Russell Jones from Felder demonstrated the new Hammer A3-26. Chris Eagles and Paul Hodgson showed two highly skilled but very different approaches to woodturning, and Peter's tutorials on handplaning and dovetailing gave visitors a feel for the sort of skills they can learn at the school and for Peter's crisply concise yet relaxed and friendly teaching style.

A fantastic free barbecue kept everyone topped up with first rate grub (Waitrose beef burgers - yummy) the weather held and the laid back atmosphere made it a really memorable day all round.

The event ended with the draw for a weeks training with Peter which, I'm delighted to say, was won by one of the people who entered through Workshop Heaven !

I'm already looking forward to next year's event; we will let you know as soon as the dates are announced.

Taste the Oak!

Oh My God! If you haven't tried this stuff you need to - it is absolutely delicious! Our postman is quite into his beers and we occasionally swap tasting notes and bring each other a bottle or two to try if we find something a bit special or unusual. I read a fascinating article about the guy who set up Innis and Gunn in an in flight magazine on the way to a woodworking exhibition in Hannover last month so I have been keen to try his brew ever since.

I've also recently been experimenting by barbecuing chicken long and slow on the gas grill with the lid closed and a big pile of oak shavings smoking away on the other side. Incidentally barbecue is a noun - not a verb, you don't barbecue food, you gently smoke it until it becomes 'barbecue'! (an interesting factoid to drop into the conversation next time your neighbour offers you an incinerated sausage with a raw middle). The best result so far has been to marinade the chicken in 1 part Japanese Mirin and 1 part Worcester sauce with a pinch of salt and a generous twist of white pepper.

The result is golden and succulent and utterly delicious with strong vanilla and toffee flavours. You can taste exactly the same oak imparted flavours in Innis and Gunn's original oak aged beer.

The concept originated when they were beer seasoning casks for distillers, the beer itself was supposed to be thrown away but the brewery workers were quietly siphoning it off for themselves. The boss's lad was working on the shop floor at the time (he had no intention of getting into brewing himself) but was so impressed that he ended up taking over the firm, abandoning everything else they were doing and focussing the entire business on what had previously been a waste product!

Net result - one of Scotland's most successful export beers ever! And I can see why. Hmmmm, maybe the postie can wait until I've been shopping again....!!!

Cambering Plane Irons

Cambering Plane Irons

A slight curvature on the cutting edge of a plane iron eliminates track marks produced by the corners of the iron on the workpiece. The most succinct description I have encountered of how a cambered iron works is as follows:

"Imagine a tub of ice cream and all you have to level it with is an ice cream scoop. First passes leaves scoop shaped hollows (width depends on how deep you go). Second pass you remove the top of ridges between the hollows - digging less deep. Third pass ditto." (Jacob Butler) posted on UKWorkshop. May 12th 2011

This is my method of cambering a plane iron, it is quick and easy to do and repeatable with quite a high degree of precision. It is informed by David Charlesworth's technique described in DVD#1 Hand Tool Techniques Part 1 and my own belief in honing guides with a wheeltrack wider than the tool being sharpened (making the guide master of the tool rather than the other way around).

Begin by wetting the lapping film with a few drops of HoneRite Gold, place a rigid steel rule (about 1mm thick) under one wheel of the guide as shown above and hone through 40 30 and 5 micron grades to produce a triangular polished facet on the opposite corner of the primary bevel.

Cambering Plane Irons

Do the same again with the rule on the other side, then repeat the process using a thin flexible rule to create a shallower polished facet on either side. Finally hone the centre of the iron flat, just as you would for a square edge.

This step is important as it broadens the shaving that the plane will take at shallow depths of cut. If you like you can also do alternate strokes with one wheel on the glass and one on the film to help blend the facets into each other. The result should be a plane iron with a smiley face. (please excuse the loss of picture quality, I was racing against the setting sun)

Cambering Plane Irons

Take the iron out of the guide, turn it over, slip the thin rule under the safe end, and starting with the cutting edge off the sheet, draw the non-bevelled face of the iron onto the 30 micron lapping film to remove the burr. Polish to a shine on the 5 micron lapping film again with the other end supported by the thin rule. (this bit is pure Charlesworth and saves a whole bunch of time and effort).

OK the light has really had it now, but this is what you are aiming for - a nice broad shaving that feathers out to nothing on either side:

Cambering Plane Irons

In this case I'm doing quite a big camber for a jack plane iron, for a smoother the thin rule would be sufficient for the ends and maybe a sheet of good quality paper for the second set of facets. For block planes and bevel-ups you need more camber because the low bedding angle will reduce its effect. The Richard Kell No.2 honing guide I am using here can camber blades with up to 50 degree primary bevels using this method. It can also handle narrow or short bladed and tapered tools that many other guides struggle with.
