A Trip to the Lumber Yard

Yesterday, I took a trip to Herbine Hardwoods in Lucketts, Virginia, just a few miles north of Leesburg and not far from the Potomac River that separates Virginia from Maryland. My goal was to lay in a supply of 4/4 quartersawn white oak for a mission-style table I am preparing to build. I came with a cut list calling for 19 six-foot boards. But Rick, the owner-operator, had only boards in eight and ten-foot lengths so I refigured on the spot. I came away with 13 planks, plus a wide, planed 8-foot poplar board for the table innards. The total was 53 board feet of oak, eight of poplar. The load, once hoisted on top of my Subaru, seemed like a lot of wood for one small table. Perhaps it is. If so, I will have some left over for another project later down the line.

Next on my list is to get the wood into the basement and sticker it (separate the boards with slips of wood to help it acclimate to my basement's humidity level). Then, while I'm waiting for it to acclimate, I will develop detailed drawings of the table which will enable me to select and cut the boards to rough length before jointing and planing. And that means taking the time to learn more about Sketchup, the free computer-aided design (CAD) program provided by Google. Sketchup has the potential to eliminate some of the tedium of making drawings by hand and produce scale plans that can be used in actual construction. Learning to use it is one of my goals for the year.

More on the table later as I progress in building it.

Dust Collection

One of my long-term goals has been to install dust collection in my woodshop. I bought a Delta 1-1/2 hp. dust collector from my brother-in-law in North Carolina last November. But he wasn't able to deliver it to me until March. Since then, it has sat in a corner of my basement waiting to be connected.

It wasn't idled for lack of need. As the photo shows, my machines were turning out sawdust piles that were making it hard to move around safely. It also shows some of the tubing I acquired to help solve the problem.
Over the last few weeks, with the help of a friend, I installed a 4 inch main line along one wall of the shop that runs behind my larger machines. Then I installed flexible tubing to connect each machine to the main line. I finished making the connections this morning and tested the system. It works great and will help keep my shop clear of sawdust.
Some work still remains. The smaller tools--router, spindle and belt sanders and drill press--will be connected later via 2-1/2 inch hose that will reach down from a 4 inch line strung overhead. But these machines, with the exception of the router, don't generate as much sawdust and so I feel able to handle them separately. Still, I'll try to get it done in the next couple of weeks, once I get the needed supplies.

A Successful Show

Friday and Saturday, I participated in a Lie-Nielsen demonstration of their outstanding hand tools held at Exotic Lumber in Gaithersburg, Maryland. I was there to help take orders, for which I was paid in credits toward Lie-Nielsen tools. I had a blast! I had never done retailing before and I found that I liked the interaction with the customers, chatting about the tools (about which I learned a lot during the show) and about woodworking in general. All told, I was there and on my feet 10 hours and never even thought of getting tired! I estimate that I sold somewhere in the vicinity of $10,000 worth of tools during the two days, my two biggest orders being $1,340 and $1,175.


I also made some purchases. My first was not from Lie-Nielsen but from Exotic Lumber, whose space we were using. They have an amazing array of special lumbers from around the world, especially Africa. Though it is a long drive for me, it will be a good place to go for special needs in the future. I bought a nice zebrawood board with straight and pronounced grain that I think will make a pretty box. I also bought a burnisher for my card scraper from Czech Edge Hand Tools; it has a beautiful kingwood handle, but what I really liked about it was the size and feel of the handle, which was better, in my opinion, than the Lie-Nielsen version.


At the end of the show, I made a few purchases from Lie-Nielsen. The major items were a low-angle adjustable mouth block plane, which was paid for by my earnings, and a 15 ppi (points per inch) dovetail saw. Lie-Nielsen has offers two dovetail saws, the one I bought and a progressive pitch model, with teeth that run from 16 ppi to 9 ppi. I tried them both on a piece of cherry and much preferred the 15 ppi model; the progressive pitch model was actually harder to start and tended to slip out of position on the first stroke. The photo shows my new acquisitions.

Another Jig Completed

I've been working on this one for a couple of weeks, off and on--a jig to cut box ends at a 45-degree angle. The basic jig wasn't all that hard to build--a base out of Baltic birch plywood, runners out of UHMW to fit in the miter track of my table saw, and front and rear fences out of soft maple. The real trick was to get the front fence squared up at exactly 90-degrees to the saw blade.

I tried several techniques before I got it right. First, I used my Wixey electronic digital protractor to try and measure to the angle to the blade. This proved to be highly inaccurate, given that the blade was leaning at the necessary 45-degree angle to the base. Then I tried cutting boards to measure the resulting angle by trial and error. At first I used a narrow board but found that too inaccurate also. Finally, I used a 5-inch wide board and after many tries was able to get the fence adjusted spot on to 90-degrees.

The plan now is to make tissue box covers using some highly figured quartersawn sycamore I was able to get hold of. That'll be the test of just how accurate the fence really is. The good news is that I can always make more adjustments if I need to.

Before I start on that, I want to hook up my dust collection system, now that my hoses and connectors have come in. But who knows, I may not be able to contain myself from building an actual project before I get that done!

Learning to Sharpen Chisels

Let's face it, I never started out to be a hand tool guy. There is something about power tools that just draws me to them. Among other things, they have (for me, at least) a mystique about being precise in application. Though I'm finding out they are only as precise as their user, still, the whole idea of hand tools leaves me with the impression of their being susceptible to misuse by my unpracticed hands.

Be that as it may, I have already found chisels handy enough (OK, essential) that I broke down and bought a set. I didn't pop for an expensive set but instead caught Woodcraft's Wood River brand when it was on sale. What I didn't count on was the fact that while they are not exactly dull when they arrive, they do need a basic sharpening to make them really useful.

The first thing I did was purchase a basic grinder, which is needed to shape the front of the blade. But after asking my friend Jeff Fleisher how to sharpen them properly, he put me on to an article about David Charlesworth's method. Finally, today I drove out to his shop in New Market, Virginia, and he helped me sharpen the first chisel so I could see and experience the process for myself.

The process is fairly straightforward, if a little tedious when doing it for the first time. Charlesworth's method calls for a series of Japanese waterstones. You first flatten the back (flat) side of the chisel to remove all the tooling marks as it comes from the factory. This involves working the back of the chisel up and down and then back and forth on either a 200 grit stone or wet or dry sandpaper laid wet on a sheet of glass. When the factory marks have been removed, only slight scratches from the stone or sandpaper should remain. You then move to a 1200 grit stone that has been wetted and repeat the procedure, working from there to a 4000 grit stone and finally an 8000 grit stone on which a slurry has been made with a nagura stone. By the time this has been done, few if any scratches should remain and the back of the chisel should be both flat and scratch free.

The next step is to work on the beveled side of the chisel blade. Here you turn to the fine wheel on a slow grinder. You mark the beveled edge with a Sharpie, then grind away the marked metal, holding the chisel at precisely 90 degrees to the wheel. When all the marking has been ground away, you should have a slightly concave surface on the bevel.

The final stage is to put a fine edge on the chisel. This is done on the 8000 grit stone using a device that holds the chisel blade at 30 degrees to the stone. Five or six pulls is all that is needed. Then you increase the angle slightly and repeat the process, again five or six times. All that's left now is to check and see if there's a burr on the flat side of the chisel and, if so, remove it by pulling the blade across the stone a few times.

The finished blade should be able to cut the top of your fingernail when gently pushed against it or should be able to shave a piece of soft wood like pine smoothly and cleanly.

So, I now have one sharp chisel. And a lot of work to do to get the rest of them ready for real use. The good news is, once the backs are flattened (the slow part of the process), I should not need to do more than touch up the bevels for a long time to come!

Preparing to Make Boxes

Today I jointed a sycamore board that I plan to use to make tissue box covers. Because it was 8 1/2 inches wide, I had to take the safety guard off my 6 inch jointer and run it through one end after the other so both sides would be smoothed. Planing it was no problem; my 12 inch planer did a good and quick job on it. When I finished the rough side, I ran the jointed side through one time to remove the groove left by the edge of the blade from the final pass on the jointer.

It was then that I turned my attention to my band saw and discovered that although I need 7 inch stock to resaw for the boxes, my saw will only accommodate 6 inches. So I got on line with Grizzly, the maker of my band saw, and ordered a riser kit for my saw. That will give me 12 inches of resaw capability. Now I'll have to get a new 105 inch saw blade to replace the Wood Slicer resaw blade I've never even used. I hope Highland Woodworking will take an exchange on it.

A Bad Day in the Shop

Woodworking is fun and most days spent in the shop are rewarding and, usually, successful. This wasn't one of them. It began when I set about removing the dado set from my table saw. After neatly packing it away in its case, I got down several saw blades from their peg on the wall to select the one I wanted to install next. As I moved around the table saw, my loose shirt tail caught the teeth of one of the saw blades and dragged it off onto the floor with a resounding clang. Upon inspection, I saw that one of the teeth had been damaged and there was nothing to do but consign it to the waste can. It was a Forrest Woodworker II blade, my best and most expensive one.

I chalked that one up to experience. Then I moved on to cutting the fences for a miter jig I'm building. The next step called for cutting through the aluminum T-track I'd installed in the maple fences. My table saw, a SawStop, is equipped with a safety system designed to stop the blade if it touches anything conductive, like a finger--its intended purpose--or soft metal, like aluminum. There's a bypass procedure, however, that allows the saw to cut aluminum without triggering the safety system. So, armed with what I thought was the correct information about using the bypass system, I proceeded to cut through the first piece of fence. No sooner than it had touched the first bit of aluminum than I heard a pop and the blade disappeared below the tabletop. After opening the table, I saw the results of my misguided handiwork--the safety device was firmly attached to the now-ruined saw blade. Scratch another blade and chalk it up to . . . experience. The good news is, the safety system works.
Now wiser about the bypass procedure, I installed my remaining saw blade and a replacement safety cartridge I'd had the foresight to purchase. Then I cut the aluminum-studded fences with no trouble. I learned a lot today. But it was a costly set of lessons.
