A while ago, I read Dave Fisher’s post on his Souped-up Sharpening Shelf and thought that sounded like a great idea to get some consistency in my gouge-sharpening. It’s not that all of my carving gouges are dull, but I’ve been hand-sharpening them, and I don’t always get the angle the same, so over time, that leads to a dubbed edge, which may be beneficial or not (do some searching and reading if you want a lot of different opinions). In any case, a badly dubbed edge is not good, and consistency will get me to a happier place.

I also got a Tormek SVS-38 Short Tool Jig to use with it, and since that wants a ⅜” rod to ride on, I bought a stainless rod, as well.

With all the pieces put together (the pieces of wood at the ends were quickly half-lapped onto the main board, and the metal rod is friction-fit into holes in those pieces), here’s how the jig looks in use.

The one other modification I needed was to put a couple strips on the bottom of the box holding one of my sharpening stones. These allow it to rise above the metal edge on my bench (which is definitely not traditional on a woodworking bench, but I find it useful) and get the gouge at the proper angle with minimal fuss.

Putting these together gets the gouge on the stone as shown below. The angle is a bit steeper than the gouge was originally sharpened at, and I’ll probably lower it in the future, but sharpening at a steeper angle like this allowed me to see the results quickly. I put a line on the side of the board so I can recreate this if needed, and I expect I’ll add more lines over time. And of course, as the gouges get shorter with repeated sharpening, I’ll need to adjust the angle by putting the board lower in the vise, which will mean even more lines on the board. But the lines on the front of the board will help me keep the board level.

After a dozen passes of the gouge back and forth, rolling it to try to sharpen the entire length of the edge, I got this:

And this:

As you can see in the second photo, I didn’t quite get the gouge rolled far enough to sharpen all the way to the edge of the bevel, but very quickly I got a mirror surface on the gouge. This was with a hard Arkansas oil stone, which is quite a bit finer than the grit the gouge was originally ground with at the factory, as you can see in the photos.

Overall, I’m pleased with this setup. It took me a couple hours to knock this jig together, plus $40 in materials, and I now have a jig which will help me sharpen my gouges in a more repeatable manner. The Tormek jig isn’t ideal for a large veiner like this gouge, as it’s difficult to roll the tool over far enough, but for 90% of my gouges, this should do a good job and help me keep them sharp, rather than waiting until they’re dull before I decide I have to sharpen.

A while back, I bought a sander designed to square pen blanks from Penn State Industries. It’s a nice little unit, but there are small pieces included and it’s not a nice shape to store, so I built a box to hold it.

Construction is pretty simple, but I tried a few things to practice them. The sides and ends of the box are angled in at a 7.5°︎ angle. The dovetails were otherwise cut as normal, which worked fine, though I appreciated having made the sides from pine when it came time to fit things together, as pine will compress a little which makes inaccuracies less of a pain.

The bottom of the box is some poplar I had on hand. Had to glue up some boards to get the right shape, and then I added cleats to hold the sander in place.

The top of the box sits over the base and the sander, and I will be attaching the sander to the base once I’m certain that’ll work. I’ll also be building storage pockets into the cover of the box to hold things like spare sanding discs and the adapter so I can connect the sander to the dust collector.

Finally, I did some practice carving on the sides of the box. Nothing super-fancy, but it felt like I needed some practice, and I know I found a half-dozen gouges that needed sharpening along the way, so it was a good time to do some carving.

That’s it.

---

Of course, that isn’t it. A friend on mastodon asked about the style of the carving. I replied:

I learned mostly from Ron Aylor, who was heavily inspired by Peter Follansbee, so yes, it’s in the style of Peter Follansbee, but at a remove. I bought Ron’s Categories of 17th-Century Mannerist Carving years ago, and mostly refer to that, but I also have been reading through Mary May’s Carving the Acanthus Leaf and some of the details are things from her book.

I don't recall exactly when this box got made, but it's extremely simple construction. Butt-joints on the corners (marching around the box) and a glued-on top and bottom. The sides, are, I think, pernambuco, which is CITES protected. It was a micro-lumber board I got as part of a larger order, tacking it onto a larger order to push it up to the amount needed for free shipping. The top and bottom are elm which had a knot that I filled with sawdust and CA glue. I think it's a pretty smooth fill, though it's slightly more obvious from the inside.

The hardware is black “tansu” hardware from Lee Valley. But when I put it together earlier this year, I didn't have any black screws, so it's got brass screws, which is something of a mismatch. They don't look horrible though.

The box is between 4 and 5 inches, by about 3 tall. Or 9x12x7 or 8 cm for you types who think in base 10. The sides and top are roughly quarter-inch (6mm) thick, and the box is finished with some shellac and some Tried and True Varnish Oil.

I have a MicroLux Drum Sander which is a nice little tool for sanding things that are too small to go through the planer. The only problem I’ve had with it so far is that the height adjuster, for the table that wood goes through the sander on, is hard to adjust by hand.

So I had a thought the other day, and decided to make a knob for it. I started with a chunk of hard maple, and cut a 4 inch square by ⅜ inch thick piece. I found the center by drawing the two diagonals, then drew a circle on it. Where the circle crossed the diagonal, I used an inch and a half Forstner bit to take off the corners.

That done, I drilled a ½ inch hole through the center and chucked it up on the lathe. Used a parting tool to make it round, and then sanded a bit to clean up the rough edges. Then I popped a ⅜-16 bolt through that center hole, got it as centered as I could by hand, and drew lines to make a hexagon around the hole.

The nice thing about a 9/16 inch hexagon is that a ⅜ inch chisel is almost the exact length of a side of the hexagon. And the ⅜-16 bolt (and nut) have a 9/16 inch head. When I put my (inch) calipers on the bolt-head in the sander, it told me 35/64 inch, which is close enough that a 9/16 will work.

After a short bit of chopping with the chisel, the bolt fit through the hex hole I had cut.

Next I made the hole a hair larger on one side with a ⅝ inch spoon bit, going about an eighth deep, and cut a short bit (also about an eighth) off the end of a ⅝ inch brass bar I had on hand (which has a hole drilled in the end from when I was making nuts a while back) and put them together.

With that done, I gave it a test. Here it is on the adjuster bolt. You can see that the brass is slightly proud of the wood surface, so it will serve as a bearing. I meant to do that!

And with the table set down, it’s now super-easy to adjust the height of the table. I think the bolt is a M6-1 which means every rotation gives me 1 mm up or down. On hard maple, one eighth of a rotation was plenty to lift the table for every pass through the sander, but I’m not sure how much of a change that is where the sanding drum contacts the wood.

Tomorrow, I’ll pull my new knob out of the sander and epoxy the brass into the maple with as little epoxy as possible. I’ll probably give it a coat of oil too. But in about an hour, I had fashioned a new knob, and I’m much happier with my little drum sander now. Yay!

Another type of grain filling is when you’re finishing and have some small imperfections, either from tear-out or from pores in the wood. Ideally, you fix as many of these problems as possible before applying any finish, but sometimes things don’t work out perfectly. This is also basically the method used in French Polishing (though that uses rottenstone rather than sandpaper as the abrasive).

Note that all of the pictures here show about 1 square inch of surface (2.5 cm square), so you can get an idea of the scale of things.

In a Russian olive bowl I’m working on, I had a tiny bit of tear-out near the center of the bowl, as shown above. This wasn’t obvious until I got some shellac on the bowl. I’m going to fill this using shellac and a bit of sanding dust (which is probably going to be mostly shellac, as well, but will include some wood dust).

First I sand very lightly with 400 grit sandpaper. Finer will work, but will take longer. Coarser will leave visible scratches. I try to sand across the depressions, so sanding dust will be deposited in them, but I’ll also use a circular motion when I’m starting because it’s quicker and lets me see what direction will work best.

Then I put a drop of oil (I use tung oil, but linseed oil will work, too) and 4-5 drops of shellac on a piece of folded up cloth. Old t-shirts work great.

The shellac I use is roughly a one-and-a-half pound cut. That is, I dissolve about 2 oz of shellac flakes in 12 oz of alcohol. You can use a heavier cut, but don’t go any lighter.

I rub this mixture onto the sanded area, also working across the tear-out. If you go with the direction of the tear-out, the cloth will tend to pull the dust back out, which is not what you want. You also don’t want to rub enough that the new shellac starts dissolving and removing previous layers of shellac. The idea is to build up the shellac, filling the voids. The oil is there mostly so that the partially cured shellac doesn’t “grab” your pad and get messed up as you’re adding a new layer on top of it (and partially dissolving the previous top layer). A little lubrication goes a long way towards making things work smoothly.

You can also see that the weave of the t-shirt has gotten filled with shellac. I typically use a fresh piece of t-shirt each session, because once the shellac is dried in the fabric, it won’t flex to follow the contours of the surface. You don’t want it dipping into every hollow, since you’re trying to fill those, but you don’t want it stiff as a board, either.

This is a fairly slow process. But each iteration you can see a little progress.

And at some point, the dust is almost entirely filling the voids, and not sitting on the surface. That means you’re getting close. The dust will compact as it gets wet, leaving a smaller void, but the results can look pretty darned good.

My take is that this is almost good enough. I think I’m going to varnish this bowl, which will flatten out the finish a little more, so maybe one more bit of sanding will do the trick. But I’m going to let the shellac cure for a while and then look at it and see. That will also give time for the little bit of oil present to cure, which will make for a tougher finish.

After the first bedside lamp with its wooden base, I wanted to try making one with a cholla and epoxy base. I started by pouring tinted epoxy into a 16 ounce cup from the dollar store, with some cholla pieces jammed into it. For smaller molds like this, I may need to start using partial pieces of cholla, as there ends up being a lot of empty space that needs to be filled with the epoxy. And pouring large amounts of epoxy can lead to a runaway exothermic reaction which causes the epoxy to foam and bubble and set very quickly, which generally isn’t usable.

With a successful pour, I pulled the blank from the mold and rough-turned it to a shape I thought would work. The only dimension I was really worried about was the top, which would have the top of the lamp meeting it.

Looking at the rough blank, there wasn’t enough room for a battery, so I glued on a round piece of cherry, which I thought would look good, then I poured a small pour of epoxy to make sure the base and the lamp body were stuck together real good.

Next I turned the base, aiming to leave it as wide as possible, giving me the most flexibility with the battery.

With the base turned, I bored a hole into the base of the lamp body. The largest diameter at the bottom was 2½ inches, but I stepped that down to an inch to make sure I didn’t make the inside of the lamp bigger than the outside.

With the hole bored and the top of the lamp assembled, I carved out an opening for the battery and glued on some feet to give a little clearance for the battery, so the lamp wouldn’t rest on the battery.

After signing the lamp, I finished it. The epoxy portion is polished with a plastic polish. The wooden base was finished with multiple coats of Tried and True Danish Oil. After the finishes have had a chance to cure, I’ll probably add a coat of furniture wax to make it easier to dust.

A while back, my sweetie expressed a desire to have a bedside lamp and a night light. I worked with a few different ideas for the lighting part of it before finding the Lanterna 3-Stage Battery Powered Lamp at Lee Valley. It’s just about exactly what I want, except it takes 3 C-cells. More on that later.

So I started by making a twisted tangential turning roughly the shape I wanted for the lamp base.

I also went searching for a rechargeable battery for the lamp. Turns out our door cameras have a battery which is just about perfect. The battery has charging circuitry built-in, and the terminals are on one end of the battery, and the charging jack on the other, so I ordered a spare battery. The only question was whether the 3.7 volt battery would drive the light circuit which was expecting 4.5 volts (yes, yes it does).

Then I disassembled the Lanterna and figured out what I could use. It was pretty easy, as there is a ⅜ inch threaded rod down the middle of the lamp holding everything together and carrying the wires from the head to the base. All I needed to do was cut off the battery holder, shorten the rod to fit my base, and then solder the wires onto the rechargeable battery terminals.

Then because my base was a little short, I cut a piece of walnut and carved out a battery-shaped hole in it, leaving the hole just large enough to slide the battery through, but tight enough that the battery won’t fall out when you pick up the lamp.

With the walnut base glued to the twisted base, finishing was just a matter of a few coats of danish oil, a coat of shellac, followed by two coats of violin varnish, and then a thin layer of carnauba wax so the lamp should be easier to dust.

My sweetie thinks it’s wonderful.

Technical notes: the battery charging circuit may not support operation of the lamp while charging. I don’t think this is a big problem, but that’s part of why the charging jack is on the bottom of the lamp. It’s less tempting to try and use the lamp while it’s charging this way. Also, Ring doorbell batteries are about half the price of the TP-Link batteries, but the charging jack and battery terminals are on the same end of the battery. Depending on your design, this may be good or bad.

Finally, the three stages of the lamp were chosen fairly well. The dimmest is slightly too-bright for a night-light, but putting a colored lens in front of the LEDs would solve that. And would be easy given the way the lamp screws together. And the current draw is low enough that the lamp should last 10-20 hours at full power, and almost a full week in nightlight mode. I think that’s a pretty decent life.

I recently had our HVAC guy out to clean my shop mini-split. He commented that it really needed the cleaning, and he was surprised it was still working well. And that I really ought to keep it cleaner. So I decided I would built a box to hold some filters to clean the air going into the split, so it would be happier in the future.

First step was building a frame to hold two of the filters I’m going to use. These are the filters I already use in my Rikon 62-450 air cleaner, so I generally have them on hand.

With the frame built, I measured the mini-split and the space between it and the ceiling. My goal was to put the filters sitting vertically, rather than the horizontal filters built into the mini-split, which sit horizontally at the top of the split, and catch dust even when the split isn’t running. I figure the filters will last longer if they’re only collecting dust when the split is running.

Everything looked as though it would fit, so I built two frames for the box. The one in the left had to work around the mounting system for the post for my post drill, which I needed because it was impossible to buy a straight 6x6 during the early COVID days, so I got a twisted one and figured a way to make it work.

With the side frames built, I cut panels to fit on them from a scrap of MDF I had. Then I used more scraps to connect the two side frames together and provide an opening for the filter holder.

Next up was to seal up the large gap between the mini-split and the filter box. But I couldn’t build anything rigid here, since the front of the split pivots up when it opens so you can clean the filter. My solution was to tape in a piece of ¼ inch MDF. Hopefully the tape will remain flexible enough that I don’t need to remove it, but can simply flex the piece out of the way.

With that, it was time to put the filter carrier in place. I had hoped that it would stay with no attachment, bu it wanted to tip forward, so I put a single screw in to hold the top of it in place.

And with that, everything was done except inserting the filters. With them in place, it’s done. The filters don’t seem to hurt the airflow from the split when they’re clean, but I’ll need to keep an eye on things as they get dirtier. It wouldn’t do to burn out the fan in the split.

While working on the Altai Project Logo carving, I discovered I needed a narrow skew in order to get down into some of the corners. I have a handful of ½ inch wide unground blanks I got from the Mountain Woodcarvers clearance page, so I got busy.

First step was grinding it down to 2-3mm wide. Then I skewed the tip, and put a rough edge on with the grinder. That’s the rough outline of the tip made.

Then I had to re-harden the steel, as the grinding had wrecked the temper. I heated it bright glowing red with a MAP gas torch, and plunged it into a jar of canola oil I keep for hardening tools. Then the blade went into the toaster oven to temper it. I’m aiming for a hardness of 60 or so, which will work well for a carving tool.

With the blade in the oven, I turned to the lathe, and converted a small piece of granadillo into a handle. I also drilled a 3/16 hole for the tang. Because it’s a tapered tang, I drilled a short bit wider with 7/32 and ¼ inch bits. Then I added a ferrule from some ½ OD brass, and filed it smooth.

By this time, the blade was done cooking, so I pulled it out and let it cool, then pounded the handle onto the blade. A bit of hand sanding and a couple coats of tung oil, and it’s ready to go.

I’ve been needing a single place to store my files, rasps, and floats for a while now. They were stored in two older tills, one of which had been repurposed from a saw till, and another which used to be something else that I don’t remember. Plus I had a number of files laying loose on various flat surfaces around the shop.

I started by building three racks to hold the files of various lengths. The largest holds 12 files, the middle holds 15, and the shortest rack can hold 20 files, though only the shortest in length will fit.

The racks are made of ⅜ inch thick oak, either 1 or 2 inches wide. Each rack has a bottom piece with indentations drilled in it, and a cross piece with magnets embedded to hold the files in place. They all pivot on the dowels that mount them (though this isn’t an especially useful feature) so they can be tipped forward or backward to access the files without knocking the ones in the rows in front. The racks were treated with iron acetate to ebonite them, though the solution was a couple weeks old, which is, I suspect, why I got a dark brown rather than a black finish.

The carcasse is built of ¾ inch thick pine, and dovetailed together, with the shelf above the drawer resting in a pair of ¼ inch deep dadoes. The drawer is also dovetailed, with half-blind dovetails holding the drawer front in place. This is the first time I’ve built half-blind dovetails, so it was good practice. The drawer-front is also carved with a design I made up over a few days of carving.

The pine is all finished with a coat of kakishibu. It’ll get a few coats of tung oil once it has had a little time to darken, unless I decide it needs a second coat of kakishibu first.

The drawer hold spare file handles, file cards, and needle files. A couple weeks of construction, the added carving on the front of the till makes it feel a little special and I also got to practice barrel and bead moulding which came out nice.
