Groovin’ tools

So the last try to make a straight line cutter for stringing didn’t work so well, the fence mortice was too sloppy. So today I cut a new one. Simple process; pick a scrap of wood from the bin (in this case a piece of walnut because I’m not averse to cheating when it comes to mortices 😀 ). I’ll reuse the beam so I mark off a line on the fence with a square, drop one edge of the beam into it and then mark the width off on the fence and carry the line around with a square; mark top and bottom of the beam with a wheel gauge using the same reference face you used for the square, and that gives you the outline of the beam on the front and back of the fence and aligned. Then drill out the middle to get rid of most of the waste:

I know it looks off-vertical, that’s because I let go to take the photo 😀
Once the hole is drilled (and from both sides, no blowout involved), it’s chopping time.

Quick touch-up on the strop first, that little dog being useful to keep the strop from dancing much, and I use the japanese chisel to chop out the mortice from both sides roughly, leaving just a small half-millimeter or so of material between the lines and the mortice. Then pare the last bit using the narex butt chisel. But I wanted a guide so the paring chisel was done at right angles and it just so happens I bought some 1-2-3 blocks recently, so…

Make sure the back of the chisel runs flat on the 1-2-3 block. You could just use a wooden block for this if you have one that’s square, but I had the 1-2-3 blocks so why not.

And when you’ve trimmed to the line, it’s time to start test fitting and fettling. The beam doesn’t initially fit; once I’m satisfied (using a square) that the inside of the mortice is square and the corners are clean, I’ll take a fine-set #4 and take a swipe off the beam, test fit it again, and then another swipe and so on. It takes a while because you’re sneaking up on a snug fit, but eventually…

It’s not bad. It’s not perfect – the beam still has more play than I’d like when it’s out at full extension, but since this cutter won’t really be asked to reach more than an inch or two in from an edge, that’s no major worry. At some point I expect it’ll loosen up due to wear and tear, and when/if that happens, I’ll cut a slot in there for a wedge like in a traditional english marking gauge and fit it with a wedge.

Not too shabby. Time for some testing.

Just cutting a groove here in a scrap piece of pine. The pizza-cutter thing and the dental pick are for cutting a slice off the veneer to test with and to clean out the groove, respectively.

Groove looks clean and parallel to the edge, feeler gauge says the width is 0.8mm as expected, and it’s not too ragged. I think that’s good.

And looking at the professionally-made radius cutter, the groove appears to be solidly comparable. I’m happy with that for now.

I’m not happy with the veneer I have though – it’s 0.6mm, or at least it claims it is (the calipers says it’s closer to 0.5), so if I test on a small scrap of walnut…

The groove is too large for one thickness of veneer and even if I put in two layers of veneer, you can still make out the hairline (and ragged) line caused by the gap between them.

I need to find a source of constructional veneer that doesn’t expect me to buy an entire tree’s worth…

Mucking about

So no major new projects taken on yet, I’ve been tidying away some new toys and getting the shed back to a working state instead. For example…

I now have two pairs of hollows and rounds (4’s and 6’s) as well as a 7 hollow, the reeding plane and a spare 6 hollow. According to Mouldings in Practice that’s all I need to start off with for the scale of stuff I build. A pair of 2s and 8s would be the next on the list if this works out. I don’t like this storage solution though; you don’t really want to have a moulding plane tip over and fall on your head from two feet up. I’ll build a rack for them seperately later .

I also wanted to increase the final grit of my sharpening setup (before the strop), and while waterstones seemed the obvious choice, they’re messy as all get-out. Also, the way I work I don’t have a huge amount of time in the shed so waterstones that you don’t have to soak for 15 minutes before sharpening would be mandatory (whether that be solved by storing them in water or having the shapton type that you can just squirt water onto and get going), and those are not that cheap. But if you want 20,000 grit, they’re you’re only real choice.

Thing is, okay, I do have a japanese chisel or two but most of my work isn’t done with A2 or PM-V11 steel or anything that esoteric, so waterstones aren’t really mandatory; and diamond plates will go up to 8000 grit if you buy from DMT. Okay, the 8000 grit one isn’t cheap, it’s nearly ninety quid, but the things last for a decade and they’re very low fuss, so I cried once and bought one.

Swapped out the 1200 grit Ultex and in went the 8000 grit DMT. The Ultex went into just-in-case storage. I’ve only sharpened the new japanese chisel on the DMT so far (it’s been a quiet week) but for such a fine grit, it visibly cuts quite surprisingly well.

Speaking of sharpening, I needed something for the inside of the gouges, so some black arkansas slipstones got bought along with the DMT. Seem nice enough, and not too expensive. Not used yet though….

And I got some 1-2-3 blocks. I’ve been meaning to get some for a year or so now. For woodworking they’re not as useful as they would be to a machinist, but not having to measure off 1, 2 or 3 inches, being able to set up the bandsaw or fences with right angles, clamping odd things, they’ll be bloody handy for that I suspect. Need to put a mount on the wall for them (I suspect a pair of dowels in the nonthreaded holes will suffice). Pain in the fundament cleaning all the storage grease off them though, but when you do, they’re nice and shiny…

This radius cutter isn’t new, I’ve had it for 18 months or so but I haven’t used it (look, life gets complicated sometimes, okay? 😀 ). I finally got to watch the line-and-berry video this week and dug this out, I have an idea for a project I want to use it on. More to come but I need to make a tool or two first…

One tool down, another to go yet. I also need to find a source for 1/32nd holly veneer, which in Ireland seems more difficult than expected.

Wanted to finish this up as it was sitting around (it’s planned to be a salt box). It’s a bit… drab as is though. If only I had something to jazz it up a bit…

*hehehe*

Well, that was… intense. Left it overnight, sanded lightly to knock back grain and re-stained it today and gave it a coat of spray laquer.

It’s not terrible, but it’s a bit more blotchy than I was hoping for. Hmmm….

Also, I had another bandsaw box waiting to get a hinge and get finished so I wrapped that up as well but with just a coat of BLO…

I have no idea what it’s for by the way, I just wanted to use up a scrap and play with making a brass hinge (learned I can’t really do it in my shed unfortunately, I’d need a proper anvil I think. Oh well).

I’m almost done with the last of the tidying up at this point. Just need to sort out this guy and that’s the last big task I think. There are other things, magnetic rails and move some tools about and other small stuff, but this one’s the awkward one I think…

Too many inches

Quite a bit of time in the shed today, so made some progress (there being a nearby deadline, this is a good thing). Started by cutting a side rail’s tenons, then marking off the other side rails from it (same as for the long rails).

I wanted to keep using the offset shoulder idea, but rather than gauging it by eye, which I can’t do yet, or sawing on one or the other side of the line, which I also have trouble doing, I decided to just mark out the shoulders and cut to the line. So I marked off the show face shoulder, ran the line round with the square to the back side, and then marked out 5mm or so of the line on the back side, then put a ruler on the line and butted the square up against that.

Problem is my ruler’s too thin. And it’s fiddly. And then I had an idea – I’m already holding a thin bit of metal, why not use it?

Put the knife upside down, butt the edge up to the line at that point on the back where the back of the knife starts sloping down to the point so I had a consistent thickness (the whole blade narrows down to the bevel slightly like a saw plate), butt the square up against the other side of the knife, then flip the knife over and cut the back shoulder line.

Works quite well. And that’s about as much of an offset as you need really, at least for something of this scale.

By the way, one of these makes it a lot easier to see the lines. It’s a little rechargeable camping light off ebay. Big Clive did a video on them and the internals were quite solid so I bought one.

It cranks up to quite a high brightness and if you just put it on the bench near the work you get a nice horizontal light thrown across the piece so cut lines stand out clearly. Plus, has a nice magnet in the base so I can just put it on a plane on the wall and it acts as a quick light on those short runs to the shed to grab something when I don’t want to plug in the whole shed but need light. Or it can grab onto the bandsaw frame and act as a work light when I’m using that.

Not bad for €6.40 delivered. Big Clive had a link to a generic ebay search if you want to grab one.

Anyway, got the side rails done.

That offset shoulder method is even faster when you don’t have to faff about cutting to one side of a line when you don’t have the skill for that 😀 And all the joints bar one fitted off the saw, which I was happy with.

What I was not happy with was the overall look of the piece when I put all the rails into the stiles to get a look at the final size.

That’s… it’s just not right. It’s square. I don’t understand that. First off, it looks clunky. Secondly, the design was not square, it was rectangular because it’s designed to hold something specific which is very rectangular.

Measuring tape time.

Width is fine, a quarter inch under but no biggie.

Depth is about what I estimated (well, a half-inch over). Still not seeing it. What are the internals?

Internal width is perfect…

And internal depth is… wait, what? 13 inches? That’s supposed to be 11, what the…

Ah. Shite.

If you change your initial sizes in your design, and you’re adding on a margin for the thickness of the material, you need to run the sums again and change the final size too. Feck. Well, at least this is an easy fix (too short would have been a bit more work). I want 11-and-a-quarter inches in internal depth, so if I move the shoulder on the side rails back by one-and-three-quarter inches, that should give me the size I want. So, out with the marking and measuring gear and the saw…

And I recut all of those tenons on the rails (and everything fitted off the saw this time, yay), and reassembled the chest.

I don’t know if the photo gets it across, but it looks a lot more right this time. Weird how your brain reacts to proportions.

That’ll do nicely.

At this point I took some time to practice carving…

Simple practice pattern, just some concentric circle segments to cut out with the v-tool.

It’s a physical skill, so you just need to practice. I’m getting slowly better.

Not sure if I’m at the stage where I’m comfortable carving the panels for this chest or not. I will be for the next one whenever that is, but this one… not sure. Might leave it.

Or not. Really not sure – if the design is simple enough, it might look acceptable…

But enough diversion. Quick side job now, splitting out blanks for drawbore pegs.

I can’t tell you how much better this job is thanks to that hacking knife. Compared to a chisel, it’s faster, more controllable, safer, and just all-round better. I tested one of the peg blanks by hammering it through the dowel plate down to the quarter-inch size, but just one (it’s a noisy job, better suited to earlier in the day even with the sound dampening in the shed so I’ll do it tomorrow).

Meantime, I rough-cut the floorboards to size.

They’re cedar, already tongue-and-grooved which is a nice timesaver. I haven’t decided yet whether I should just rebate them into the base or whether I should groove three rails and nail them to the fourth (which is cut narrower). Need to figure that out tomorrow.

At this point, I got out my #04 and stropped the blade and reset the cap iron and started cleaning up the rails and stiles.

And then I set up to do some of the decorative features I had in mind for the rails. First, some fences to hold the bottom rails in place.

This wasn’t great, the piece kept spinning out, so I added another fence clamped to the front as well:

This worked nicely. It’s effectively an ad-hoc sticking board, and I’m going to use my new 167-year-old reeding plane on the bottom rails. This was the point of buying it, after all. And I’ve learned I’m not that good at using the thing, though I’m starting to get the knack of it. I think I need to get some slipstones to sharpen it a bit more (the strop only sortof works) and I’m starting to think I need to go buy and read “Mouldings in Practice” because even when I finally get the iron set to take a fine cut so it doesn’t chatter, it still digs in in the last half-inch or so of the groove and I’m sure it’s something I’m doing wrong. But I got it working well enough to do the bottom four rails. Not before I discovered that I need to do some repairs though…

It is somewhat disconcerting to hit your moulding plane with your plane hammer where you’re supposed to hit it to retract the iron and have bits fall out. It’s even more fun when you go to advance the iron and don’t realise the wedge is loose. That iron can really get some distance on it when you give it a belt with a hammer when the wedge isn’t holding it in the plane. But I was able to get it back from behind the bench without any damage, so that’s allright.

Anyway, the top four rails get a different treatment, for which I needed my scratch stock.

Lee Valley. It’s a luxury I know, but it wasn’t that expensive (it was about $50 plus P&P for the stock and all of its scratch cutters) and it works very nicely once you get the hang of it and only try to do short strokes instead of long runs (you do a few of those but only at the very end when the moulding is well established, and you have to be careful even then that it doesn’t dig into the grain and dive off to one side or the other). I used it to cut a pair of beads separated by a gouge’s width on the top rails, and called it a night there. I have some work still to do on the decoration, but it requires belting a gouge with a mallet so it’ll be loud so again, I’ll wait till tomorrow for that.

Not too bad, though a little more ragged than I’d like in places even after burnishing with a handful of shavings. But it’s not done yet…
