Paper Towel Holder


In all its naked glory
My first attempt at faceplate turning is the base of this paper towel holder. It's a hefty chunk of gnarly oak, and it showed me the virtue of wearing a face shield while turning, by exploding a bit under the chisel. That dark patch was a submerged bark pocket, and it didn't like being interfered with one little bit.

Fulfilling its purpose
The shaft is a bit off an old garden umbrella; it was turned between centres and is about 320mm long. I don't know what that timber is; it has a figure a little like rewarewa, but much finer. It's fairly light in weight, so not silky oak or anything like that.

The base is about 160mm in diameter and 50mm thick, and that much mass of oak is sufficient to create a bit more vibration in the lathe than I've been used to — especially before I realised I hadn't screwed the wood hard up to the face-plate on one side, so everything was turning slightly skewed. It got a bit better after I attended to that, but I don't think my little lathe would be very happy with anything much bigger than this.

Rough-Sawn Macrocarpa Stool

This is a stool entirely for the Outside, that I whipped up in a few hours from a macrocarpa board I found hiding away down the back of the section.

It's very simple, and as far as is possible, without subjecting its users to the dangers of splinters, I've kept the original rough-sawn finish — I've just sanded it down a bit to smooth it off.

I've applied no finish to this one. I'll just leave it out in the weather, and over a couple of years it will develop its own silvery weather-beaten patina.

Three-Legged Stool

I made the legs for this stool playing around on my new lathe, and they're as long as it can manage in its present configuration, which is about 420mm.

I'm not usually all that keen on staining wood; I'd rather just oil it and let the natural grain and colour come out. But this is made out of low-grade H4 treated pine, which has a rather unpleasant murky grey-green cast to it, so I coloured it to disguise that.

The stool is solid and comfortable to sit on, but aesthetically I think the legs could have done with another few degrees of rake.

Chisel Handle

A friend has loaned me a great armful of turning tools (thanks!), some in dire need of some TLC and others needing little more than a scrub up with steel wool and some sharpening.

I've got some of the rustier ones in a vinegar bath right now, and I used some of the cleaner tools to whip up this chisel handle out of white oak. The ferrule is a copper plumber's gland, the striking hoop is a bit of copper pipe.

I don't actually have a need for a chisel handle right at this minute, but I wanted to practice turning to precise sizes (for the ferrule and striking hoop). I'm doing it at the moment with the aid of calipers, but there's a tool that clamps on to a cut-off tool or scraper that makes the process almost idiot-proof, and I'd like a bit of idiot-proofing.

New Lathe

I spent all my meagre savings on a small wood-turning lathe for myself. It's pretty good for the price; a decently solid cast-iron construction that gives minimal vibration, and a 5-speed pulley system. The maximum distance between centres is about 420mm, so maybe just long enough to turn a chair leg on — there's an extension available for the bed though, which I may invest in at a later date if I find I need it. The only thing about it that I'm not that impressed with is the tool rest, which is very short, only 150mm (6") long. That will need to be addressed at some stage.

I enjoyed turning when I did it at 'tech, but I've done very little of it, and none at all for years, so what skills I had are now very, very rusty. It's going to take a bit of practice to get my hand back in.

My first very modest practice piece is this awl handle, made from a scrap of oak. The blade is an old 3mm drill bit shank.

Oak is a bit mixed as a turning wood. It's hard enough to cut crisply, but it has a fairly open grain, so the surface never looks as smooth and clean from the knife as fruit woods like apple or cherry. However, that's what I've got, so that's what I'm practicing on.

Mitre Saw Wheely-Stand Thing

I've had my mitre saw clamped to a folding workbench thingy (basically a cheaper version of the Black & Decker Workmate) for years. That was fine, but it was troublesome to shift around, and in my rather cramped little workshop I need to be able to shift things around so that they don't interfere with each other when I'm trying to use them.

So, I made this stand out of el-cheapo treated framing timber and some unexpectedly expensive locking castors. It doesn't look like much, but it's sold as a rock, and it gave me lots of practice at cutting mortice & tenon joints, bridle joints and lap joints.

We have bamboo growing in our garden, and I thought I'd use some as railings for the upper shelf, to stop things being pushed out the back or falling out the sides. Bamboo is good for that sort of use, as it's both thin and strong, and it will get stronger as it seasons. The down-side to it is that nature is distressingly imprecise in its sizing, and I had to do quite a bit of searching to get canes that were all within a size range that would fit my available drill holes.

As a side-effect of all this, I got my clamps a bit more organised and accessible. Next, I'll have to get a concrete pad under where the saw usually stands — at the moment it's sitting on various bits of wood spanning the rotten boards underneath, which isn't ideal.

What I Did Today

This afternoon I shifted a whole lot of wood and crap so I could shift some drawers so I could shift some bins so I could shift my mitre saw so I could shift those drawers again so I can use my table saw without banging bits of wood into things.

For a brief moment I marvelled at the unexpected amount of space I had.

Then I shifted all the wood back in again, which filled up most of that free space, and I realised that most of it is just rubbish so I'll have to go through it and start chucking most of it into the firewood pile.

And that's what I did today. Now I'm drinking cold beer, which is better.

(At some point I'm going to have to lay some more concrete so I can shift a workbench so I can shift my bandsaw to a more usable position, but not just yet. Not just yet.)

Yet Another Stool

I made another stool, this time out of some fairly dodgy, knotty white oak off-cuts. I had to work hard to get some decent lengths out of them, but persistence paid off in the end.

Our stool supply is outstripping the number of bums available to sit on them in normal daily life, but they'll come in handy for perching guests on.

I made many, many mistakes in building this. Perhaps I may learn from them, but who knows?

Vroom Vroom

Ball point pen, about 150mm wide

Stool Sample

I had a macrocarpa plank that was getting in the way, so I turned it into this stool.

For some reason it seems to me that it has a somewhat ecclesiastical feel, probably because of the scallops and what-not.

I like working with macrocarpa, but I can't say I'm especially fond of the knots. They tend to be dead knots too, so they fall out.

The stool is 600mm long by about 450mm high, a very comfortable sitting height for me. It's long enough for two people to sit on, as long as they're two very friendly people.

Router Plane Revisited

I went back to the oak router plane I made a while ago and added some handles. It worked OK without them, but they give me a bit more control and it's easier on the hands this way. They're just a pair of tawa drawer-pulls.

Because its depth adjustment is by tap-and-hope rather than by means of a screw thread, it's a bit tricky to use with the precision of my Stanley or Record routers, but nevertheless it's pretty smooth and easy to use once you get used to its little quirks.

I'm using Veritas cutters in it, and though they're excellent cutters, they've introduced a complication.

As you can see, the back of the cutter curves forward towards the sole — I'm not sure why, but probably just as a side-effect of the tool's production when they're bent into shape. Anyway, the effect of this is that if the cutter is set to too shallow a depth, when the eye-bolt is tightened, it engages over the curved section and cants the cutter forward, and the edge of the blade is suddenly much deeper than one might have expected.

I have a couple of ideas for ameliorating this issue.

The first is to add a sleeve, anchored to the top of the router, through which the shaft of the blade runs. That should help some, and it's the most straightforward solution, but it won't entirely eliminate the problem because it will have to be fractionally loose on the shaft to allow the cutter's depth to be adjusted at all, and any slack will still allow the cutter to cant forward ever so slightly when it comes under pressure from the eye-bolt.

The second is to cut out the existing eye-bolt housing entirely, and glue in a new block in which a new housing is cut that will engage higher on the shaft of the cutter. I'd say, for safety's sake, the eye-bolt really needs to be engaging at least 10 mm higher up the shaft of the blade. That's a pretty major bit of surgery, and it would probably be quicker and easier just to make a whole new tool, taking into account what I've learned from this one.

Next Day:

I added a collar to restrain the forward movement of the cutter when the eye-bolt is tightened, and it works well. It's made out of a 100mm (4") nail.

It looks a bit unsightly, I admit, but it does the job, and as an added bonus it ensures the cutter sets square to the cut. It can't be seen from this angle, but there's a vertical groove in the body of the router that ensures that the shaft is square vertically.

As I suspected, it doesn't eliminate the issue completely, as it has to be loose enough to allow the cutter shaft to move up and down, but the unwanted movement when the cutter is set shallow is now minimal, and much easier to compensate for.

Mortise Gauges

I have several mortise gauges. The marking, or mortise, gauge is an incredibly useful tool; it would be possible to get by without one, but it would make one's woodworking life a lot more difficult.

If you don't know what a marking gauge is, it's used to scribe a line, or in the case of a mortise gauge a pair of lines, accurately relative to the edge of a piece of wood. What you do with it is set the block on the shaft at the distance you want the line, and then run the block along the edge of the wood so that the pin (or pins) in the shaft scores a line.

The top one is the first one I ever bought, and the simplest. It's made of beech, manufactured to quite decent tolerances, but it's not that easy to use as a mortise gauge because the secondary mortise pin is free-sliding, which means that you have to hold several things in place at once before tightening it up. It can often take several tries to get everything properly spaced, relative to each other. However, as a simple marking gauge (just using the single-pin side) it's great. I've modified it very slightly by re-shaping the pins from a conical section to spear-pointed triangles, so they cut the fibres of the wood rather than crushing them — this results in a much finer, more accurate line, but being so fine it can be difficult to see. especially in timber with a pronounced grain like oak.

The middle one I was given as a birthday present some years ago. It's quite old, and very well made from rosewood with brass inlays. It has a screw adjustment in the shaft for setting the mortise width, so it's a lot easier to be accurate when setting the relative positions of the block and the two mortise pins. Its only issue is that, being so old, it's been used a lot, and the pins have been sharpened and resharpened so much that they're mere nubbins. They could be replaced, but I'm not really confident enough of my skills to try it — it's not a straightforward disassembly job, and I fear that I might destroy it in the attempt.

The bottom one is one that I just bought by mail-order. It wasn't expensive, about twenty bucks or so, but it should see me out. It's made of Malaysian ebony with good, chunky brass anti-wear inserts on the face of the block. Like my rosewood one, it has a screw adjustment for the mortise pins

It has (or had) one significant issue though: the hole in the block had been machined too large, so the shaft rode quite sloppily in it. That would mean that you couldn't guarantee that everything was square when tightened up.

I fixed that by adding a pair of copper shims, one on either side of the shaft, to tighten everything up. You can see their ends folded around the face of the block (there's a similar flange at the back) to hold them in place. I cut a shallow recess in the face so that the shim rests below the surface of the block; that just ensures that it doesn't accidentally ride against your work-piece and send your line off its proper path.

I'll probably re-shape the pins the same way I've done on my beech gauge, but I'll give it some use first to see if that's really warranted.

Stool

Today I gave my DeWalt thicknesser its very first outing on its shiny new wheely-stand, and used it to plane down some bits of macrocarpa that I had lying around from another project that never got off the ground.

I put together this sitting-stool, which is shown here having just had its first coat of linseed oil. It will most likely end up being another piece of outdoor furniture; macrocarpa is a good timber for that.

Just as an aside: when I was a kid, I thought macrocarpa was a Maori word, not Latin. I thought it was makorokaporo. I have no idea what, if anything, makorokaporo would mean though.

Tanto

In my scrap pile today I found a very curly bit of oak. It has grain going about seventeen different ways at once, and was impossible to work with any of the bladed tools I own, so I made this wooden tanto for aikido training entirely with rasps and files.

It's actually a pretty shitty piece of timber for almost any purpose, but I really like the chaotic figure of the grain.

Wooden Router Plane - Finis

I finished off shaping my wooden router plane, and gave it a few coats of shellac and a spot of wax.

It works fine, but it's not going to be taking the place of my trusty Record or Stanley routers any time soon. It'll be purely an emergency backup extra router, in case I should need one.

Making a Wooden Router Plane

This may not look like anything much, but it's actually a fully functional router plane.

Admittedly, it's not a very beautiful router plane just yet, but it works as one, which is the important thing. It has some shaping to be done as yet, now that I know it works as expected, and I also want to add a couple of tee-nuts so that I can mount a grooving fence to it.

The cutter is from Veritas, and is the same format as that for the Stanley No.70 or Record No.71 planes. It's held in place by a ¼" threaded eye-bolt which passes through the body of the router to a wing-nut at the back.

The wing-nut is functional, but uncomfortable, and I'd like to replace it with a knurled thumb-nut at some stage.

I've learned a thing or two from this so far, and I may (or may not) make another.

Cunning Dovetail Jig

 This may not look like much, but in fact it's an amazingly useful and cunning dovetailing jig that makes cutting dovetails a piece of cake. It's a variation on a jig developed by Paul Sellars.

One of the crucial things to get well-fitting dovetails is getting your cuts dead square, which is especially tricky on very thin stock. I've been making a bunch of small boxes out of 8mm thick pine, and 8mm doesn't give you much leeway to gauge your accuracy visually.

The thick base of this jig allows you to get your cuts square every time. Its been marked and cut with one raked cut for a side of the dovetail, and one horizontal cut, for a shoulder. In this instance I only need one tail, but it can be easily expanded for multiple tails.
NOTE: The observant will note that there are actually two shoulder cuts, but I realised that by putting a registration peg out in the middle of the tail I'd only need the one.

The piece to be cut is put into the jig, hard up against the side piece and hard up against the top registration peg(s).

Then the saw is offered into the dovetail cut in the jig, and the first cut is made.

The piece is then flipped over, and the cut on the other side of the tail is made the same way.
Note: I'm not left-handed; this is a posed shot for the camera.
Next, the whole lot is turned sideways in the vice, and the first shoulder cut is made in the same manner.

Again, the piece is flipped over and the opposite cut is made the same way.
Note: that left-hand cut is one I included before I realised that a registration peg in the middle of the tail would give more accurate symmetry than relying on allowing for the depth of the shoulder with the original corner peg.
I didn't time my work, but I'd be surprised if it took more than four or five minutes to complete each piece, with guaranteed accuracy. It would be longer of course if you're cutting multiple tails, but it's still much faster and more reliable than doing it all by eye.



There are a couple of changes I'd make for future versions.

  1. I'd make the jig back-plate a bit wider, say about 25mm wider than the work piece, so that the saw starts its shoulder cut more reliably square. On this one, there's only a couple of millimetres from the edge of the piece to the edge of the jig, and though it worked OK, more depth would be better.
  2. The top registration peg in the corner isn't really necessary. A single peg that sits in the middle of the piece's tail is adequate to ensure that everything is properly registered for cutting.

Saw Conversion Complete (mostly)


The conversion of my cheap gents' saw into a rather nice dovetail saw is pretty much complete.

It's now completely usable, and it cuts very nicely with a good thin kerf.

Alas, it's still moderately hideous from its left-hand side until I can figure out a decent way to hide the captive square bolts. They don't affect the saw's functionality in any way, but they're aesthetically unpleasing.

Saw Conversion


I have an inexpensive gents' saw that I'm converting into a pistol-grip dovetail saw. I'll have to remove the saw's handle, cut off the tang and reshape the plate slightly, and then mount it into the new handle I'm in the process of shaping from a piece of 25mm thick oak I had lying around.

The existing saw is OK, though not great. The steel is decent and it cuts well, but its back-spline is a little light. Ideally I'd like to change that for a good stiff, heavy brass one, but I'm not sure that I'm capable. For the moment it can stay with the existing spline; I can always swap it out at a later date with only minor surgery to the new handle.

This is more or less how it will look when it's assembled. Of course, the grip will be shaped so that it's a lot more comfortable to hold.

One thing that's troubling me is the pair of nuts and bolts that should hold the plate to the handle. Traditionally they should be brass split-nuts, in which the bolt (or rather, machine screw) part of the pair screws into a threaded, capped tube. This gives the assembly a very neat look, but as far as I can find they're just not available anywhere in New Zealand except by cannibalizing some from an old saw. I can get some from overseas, but they're quite expensive in themselves, and the postage being demanded by the vendors is eye-watering — one mob in the UK wants £45 in addition to the cost of the fixings themselves!

Well, they're not essential; I want to use them mostly for aesthetic reasons. It would be nice to have some though, not least because I have some missing from some of my other saws that I'd like to replace.

Later....

I finished the shaping of the handle, and gave it a single coat of oil just to seal it.

I drilled a couple of small guide holes where the screws will eventually go; there's no point in going any further with them until I know exactly what hardware I've got for them.
