Woodworking is Good for the Brain

§ by on March 30th, 2009

Stimulate the BrainThe older I get, it seems I’m making more frequent trips to the doctor’s office. If it’s not for an exam, there’s blood to be drawn for lab tests. As my dad is fond of saying, “It stinks getting old.”

But fortunately, woodworking is one of those hobbies that can help keep us — more specifically, our brains — younger. I ran across this article this morning in the Imperial Valley News out of San Diego.

To quote the article:

“A hobby like woodworking, which stimulates the mind through complex measurements, visualization and creative problem solving, can have significant positive effects on the aging brain.”

To me, it’s just another reason to head out to the shop.

Add a Bench Knife To Your Benchtop

§ by on January 30th, 2009

blog-5-bench-knife-0351Last night I undertook the task of cleaning 2 weeks of accumulation off my benchtop.

Some of the clutter was the remnants from fun projects. But mostly it was the residue of home maintenance – sound familiar? After cleaning the benchtop, I got to thinking about what items I would allow to remain.

Now, there are the tools that we own, and then there are the tools that we actually use (a much smaller list). I like to keep my benchtop clean and not use it as a storage shelf. But, I’ve got a couple of tools that never seem to leave my benchtop because I use them constantly. They include a small square, block plane, dust brush, mallet, measuring tape, a mechanical pencil, and finally a bench knife.

A bench knife can quickly round the edge of a tenon that needs to fit into a routed mortise, clean a tight joint, bevel an edge, and do many tasks quickly and easily. And it is a wonderful companion to my block plane and chisel.

Now, by bench knife, I don’t mean a utility knife. Utility knives are great for straight down scoring and cutting thin materials like carpet, tar paper, matboard, and the like, but, utility knives are not woodworking tools. The blades wiggle about, are too wide, and the handles are designed only for an inline power grip making fine control very difficult.

A bench knife is a woodworker’s tool. It should have an appropriate handle size and shape, one that can easily be gripped and pulled in conjunction with using the thumb to brace against the workpiece, similar to the motion of making a fist, or firmly and comfortably gripped to push the blade away, or make a piercing cut.blog-5-bench-knife-0252

A bench knife should have a tapered blade so that the tip can get into tight spaces yet the base of the blade is stout enough for heavy cuts. Also, the blade should not flex (flexible blades are for peeling fruit) and a cross section that can “roll” into and out of a cut.

And forget about A2, cryogenic steel, molecular packing, or any steel-related voodoo you may have heard about. Tried-and-true high carbon steel that has been properly heat treated makes a wonderful blade that has the right combination of toughness and edge-holding ability.

For a purchased knife, my favorite is a 2″ knife by Frost. It’s a plain unadorned knife and the price is reasonable. I used this knife daily for years carving figures as part of my former life as a craftsperson, so, I can vouch that the blade is of good quality with a shape that makes it quite versatile. The center swelling of the handle is comfortable and allows for a variety of grips.

blog-5-bench-knife-0201So think about adding a bench knife to your benchtop. There are the tools we own, then there are the tools that we use. A good bench knife is a tool that you will use.

P.S. Off in the future the making of a bench knife may be a project in ShopNotes. My first prototype uses a purchased knife blank to which custom wood scales have been riveted on. The nameplate is a fun addition. (Who doesn’t like to personalize their tools?) I may also custom make a knife blank from tool steel.

Planer Snipe…with a Twist

§ by on December 10th, 2007

I had recently acquired a barely used planer from Sears. It was one of those deals where the price was right and I couldn’t pass it up.

When I first brought it home, I fired it up and ran a few boards through it. It seemed to work great, but I didn’t need it right away, so I stored it under the bench. Let me say right here that when Sears calls this a “benchtop” planer, that’s an outright lie. This monster is heavy. I’ve got to build a stand for it one of these days. But I’m getting sidetracked.

While I was in the process of building the project mentioned in this previous post (where I injured my thumb on the table saw), I needed to plane some 3/4″ curly maple boards down to 1/2″ thickness. (Yes, it broke my heart to see 1/4″ of those boards go to waste as chips.) As I was planing, I noticed that there was a wide, shallow groove along one edge of the boards along the entire length. Since the two boards I was planing were cut from longer stock, I thought that the boards were rough-planed that way and that’s how I brought them home. A couple of shallow passes later it dawned on me that the groove wasn’t going away. “Great,” I thought. I was going to have to tear down this planer to see what was going on.

Fortunately, this planer is designed to make it fairly easy to get to the cutterhead. A few screws remove the dust shroud to gain access to the knives. As I rotated the cutterhead around, I couldn’t believe what I saw. The gib holding the knife in place was bent outwards and the remaining cavity between it and the knife was crammed full of chips. You can see what I mean in the drawing at right. (I tried to hightlight the area in red.) The item labeled ’65′ is the gib. Item ’64′ is the knife. (Item ’60′ is the cutterhead.) Now, what to do?

Figuring that the worst-case scenario was ordering a new gib, I attempted to straighten it. I clamped the bent area in heavy-duty vise and torqued it as far as I could go. That took care of the majority of the bend. Then some carefully placed taps on the leading edge of the gib with a wood block and hammer took care of the rest. Some minor filing was all it took to get a smooth, straight edge. I re-installed the blade and gib and ran a few boards through it. No sign of a “groove.” I was relieved and glad that I was able to repair it.

But the question remains…what caused the gib to bend in the first place? It’s possible that it was like that when I first bought it. But the mystery remains. When I talk to the other guys in our shop, no one can come up with a plausible explanation. Very strange. If you’ve got any thoughts, leave a comment here.

Table Saw Safety Hits Home

§ by on December 8th, 2007

It’s been a rough week. Sunday night, I was in my shop working on a small project. It was nearing dinner time and my wife stepped into the shop to inquire about my plans for dinner. I was in the middle of resawing a small workpiece. I knew she was standing there, so it didn’t startle me. But something happened to the workpiece and in a split second it kicked back with a loud bang. I instinctively shut the saw off and reached for the workpiece.

Then I saw it. The workpiece was not the only thing I was cutting. The end of my right thumb had somehow come down directly on the spinning blade. I hadn’t even felt it.  Yet. My wife saw the whole thing happen.

The end result after some microsurgery is a shorter thumb without a thumbnail. I’ll spare you all the gory details. The prognosis for a full recovery is good after some physical therapy.

But what I have left to deal with now are all the questions. And anger and blaming myself for letting it happen. I haven’t been back to the “scene of the crime” since it happened. I suppose I’ll have to face up to it here in the next day or so.

I lay awake at night second-guessing myself. Not believing that I’ve been woodworking for over 30 years without serious injury.  The full range of emotions and “what-if” scenarios.

I’ve already wrestled with the 100 different ways I could have accomplished my goal that night. And what I should have done differently. The constant blame game you play in your mind.

But that’s behind me and life must go on. My point of telling my story is that you should always listen to that voice in your head that says, “Perhaps I should do this another way.” For that’s exactly what I was thinking precisely one-half second before I permanently injured my thumb.

Going Nationwide: The Woodsmith Shop TV Show

§ by on November 29th, 2007

If you’re a subscriber to Woodsmith or ShopNotes magazine, or live in the state of Iowa, you probably already know that we’ve been busy around here. We’ve been working hard on a new TV show that has been airing on public television (PBS) stations in Iowa and will soon be available nationally in December.

The Woodsmith Shop is unlike any other woodworking show you’ve seen. It’s the first one to be filmed and produced (by Iowa Public Television) in High Definition. That means the picture quality is unsurpassed. You’ll see all the details of the tips and techniques we talk about on the show.

Second, The Woodsmith Shop isn’t a project-based show. What I mean is we’ll spend an entire episode talking about a particular woodworking joint, tool, or technique instead of building a project. That means you’ll get more detail about woodworking than you’ll find on any other show. And you’ll have the opportunity to download project plans and articles from our web site that are related to the show’s content.

We’ve been getting a lot of positive feedback so far from those that have seen the show. And a lot of folks nationwide are anxious to take a look. Now is the time to take a minute to email or call your local public television station and tell them you heard about The Woodsmith Shop and want to see it in your area. This link will take you to the show’s web site where you can find out if the show is airing in your area. You’ll also get a list of PBS stations in your area and a contact link for each station.

Let us know what you think of the show.

Miter Saw Product Recall

§ by on November 28th, 2007

Well, the news from the Consumer Product Safety Commission keeps rolling in. Today, I received notice that Performax and Wilton miter saws are being recalled. These are Chinese import brands distributed by WMH Tool Group (makers of Jet and Powermatic tools).

Here’s the hazard they’re reporting:

“The saw handle’s switch can fail, causing the saw to smoke, spark, and trip circuit breakers, and disable the safety brake. The saw also can keep operating unless the unit is unplugged, posing a laceration hazard to consumers.”  

Yikes.  You can contact WMH Tool Group for a new saw or a full refund if your saw is included in the recall.

For additional information, contact WMH at (800) 689-9928 between 8 a.m. and 6 p.m. ET Monday through Friday, or visit the firm’s Web site at www.wmhtoolgroup.com.

You can read the entire text of the recall notice here.

Shop Light Product Recall

§ by on November 26th, 2007

I’ll admit it. When it came time to set up my shop, I didn’t want to spend a lot of money on lighting. Yep…I’m cheap. So I went to my local big box store and picked out the least expensive flourescent shop lights I could find. But just so you don’t think I’m a total cheapskate, I did upgrade half of the tubes to the newer (and more expensive) daylight or full-spectrum tubes for more natural lighting. I learned that lesson from our new shop here at August Home Publishing. Natural lighting makes a big difference.

Now, my cheapness may come back to haunt me. The Consumer Product Safety Commission has sent out notification of a product recall for shop lights made by Cooper Lighting. You can read all about the recall here. To see the announcement on the CPSC web site, click here.

Well, since my shop lights look suspiciously like the ones that are being recalled, looks like I’ll have to climb a ladder and check them out. And if yours look like the one shown in the photo here, you should do the same.

Fitting a Panel into a Frame

§ by on November 5th, 2007

This weekend was one of those weekends when my lovely wife made it very clear that she had some things she wanted me to get done around the house. One of those tasks I had managed to put off for over a year. 

She wanted a white board put up in the kitchen so she’d have a place to write her grocery list, notes, and whatever else came to mind. Our 1960′s-vintage kitchen still has the original cabinets with the rabbeted plywood doors. But the way the cabinets were built, there’s a bumpout in one corner that is essentially the back side of a closet. Strange floor plan, I know, but this whole house is strange. Anyway, where the wall cabinets meet this bumpout, there’s an adjacent empty space on the wall that had been framed in 1×2′s. The area is about 28″ high by 14″ wide. A perfect size and location for a whiteboard, my wife so strongly hints.

So here’s the challenge:  Can I get a ¼” whiteboard panel to fit inside this framed area without having to add trim to hide any gaps? I brought in my framing square and was pleasantly surprised to find out that one corner was only out of square by about 1/8″ over the 28″ length. “Hmmm. Not bad,” I thought.  “This will be easier than I thought.”  (Usually, this thought gets me into serious trouble…but not this time.)

I cut the panel just about 1/16″ oversized on my table saw and kept trimming a little off until the panel just started to slide into the “narrow” end of the frame. Knowing that I had to take about another 1/16″ off the other end of the panel, I went back to my table saw, folded up an old business card to four thickness, and put it between my panel and the rip fence at one end. That effectively “tapered” the cut. I checked the fit of the panel and it was real close to fitting. So I brought my small block plane into the kitchen and kept shaving the edges here and there until the panel could be held in place with friction only. Of course, my ten-year old walks in while I was planing and says, “Dad, why are you doing that in the kitchen?”

After a few rounds of planing and test-fitting, I ended up not needing any glue or screws to hold the panel in place. And there was barely any noticable gap around the panel. Nothing beats a block plane for final trimming and fitting.

I was happy to get another project checked off my list and my lovely bride was happy to have a place to make a list.
