Shooting Boards and they’re Red Hot!

Shooting Boards and they’re red hot, yes I’ve got em’ for sale!
I have to thank the early bluesman Robert Johnson, for the inspiration on the title here. I have been getting some email reminding me to come up for air and write a little bit here, as I have been working with my head down. With that said, I am still amongst the living!

Here’s a photo of a pair to draw to. The shooting boards, shown here in left and right-handed models. You could almost call them V-Twins, but darn it, somebody already thought of that…

Back in late March 2009 I revealed I was going to be making a shooting board with an accurately calibratable fence, which can be fixtured in six positions. Woodworkers found this very interesting! I want to take a moment to say thank you to all who have purchased one. It has been a warm and well-received response from the woodworking community. I plan to continue making them, and even have a few ideas to accessorize them as well.

Introducing a Shooting Board from Evenfall Studios.

One of the coolest things about hand planes is the finish they leave behind. We have all seen the finish quality they are capable of free hand, but when you put hand planes on jigs, a door is opened and passed through where clean, straight, and angular accuracy becomes something that is hard to obtain in any other simple way.

Yes, I am talking about shooting boards.

Shooting boards are one of the gateways to fine woodworking. Sure, there are many gateways, but the shooting board, in its different configurations guide the cleanest edges and end grain cuts to the finest accuracies, the most spectacular fit and finish, and it puts this capability in the hands of any woodworker.

I have always enjoyed woodworking jigs, and have made a number of shooting boards over the years. I have thought about many different designs for a long time. I’d have one that did this, but not that, and wish I had one that did that too, but then, that method can become a stack of shooting boards, and most of us don’t have the space for that. It’s true; there are some very specific types that are meant to cover specific uses. Others are great for general work, but the worry over wood movement and long-term accuracy causes some folks to question how much energy to put into the making of their own.

I decided to try designing a shooting board, using a design that encompasses the many qualities that I felt most woodworkers would most desire and need in a basic shooting board. Reinforcing as many strengths as I could, while diminishing the weaknesses where possible, and offer it for sale to woodworkers who may be interested in a shooting board that can cover a lot of fine woodworking situations, yet may not want to build one of their own. If you are interested in purchasing a shooting board, I’d be happy to build one for you. Please see the details at the end of this article. Continue Reading »

The Foibles of Tape Measures

For the average user of a retractable tape, there can be some usages of a tape measure that unwittingly reduce its accuracy. Basically, many people are not even aware of these details. I did say usages, but there are also problems inherent with the way a tape measure is made, that for fine work, render it a tool which is not always the best tool for the job. When we ask a tool to wear too many hats, it fails to do as well by us as we may think it should. It is good to know what some of the weaknesses are so we can learn to accept what are and are not good practices for the tape measure.

tapes1.jpg

When you are buying a tape measure, there are several available features that you can consider. For shop use, furniture making and cabinet making, you will rarely need a long tape, but the long tapes have features that enhance accuracy. They come with 1-inch wide tapes, which are easier to read for eye relief, harder to distort and are more rigid. Often the 1-inch tapes include more rivets on the hook, which lend themselves to resistance to wear and stretch. Unless you need a shorter tape for handy reasons, I recommend the bigger tape just for its added stability. Continue Reading »

The Challenges to Squareness

Yup. The Challenges to Squareness.

You didn’t actually think this was going to be easy did you? Well, it isn’t always, but I think the endeavor of overcoming some of these challenges can make things better, especially if you like taking good to great. Knowing what some of the issues can be, and how to overcome them when and if they arise, can help our results better match our desires.

We learned in The Constructs of Squareness article that geometrically speaking, a right angle is 90 degrees, and if it isn’t 90, then it isn’t a right angle. Everything can be represented perfectly on paper, in CAD drawings and in theory, but in building, milling, and manufacturing there are a number of factors, which can affect the quality of accuracy. Some we have to accept, some we can learn to work with, and knowing the difference is how we approach closer to fine, if fine is the goal.

Things that affect the accuracy we use to build do vary. Goals, philosophy, materials and tooling all play a part.

Goals affecting accuracy are often production oriented, cost oriented, or what the intended use of a final product is. If the Goal is to build a doghouse, it needs done quickly, and the price of materials and labor needs kept low, then, the accuracy of squareness need only be relative. If the goal is to make a jewelry box, where scale is small and appearances will be highly scrutinized, then the accuracy of squareness becomes much more important, because the philosophy behind jewelry boxes is seeing how far craftsmanship can be taken. Close tolerance fit and finish is a very large part of how this type of work will be evaluated. Continue Reading »

Sharpness Flatness Godness Agnes!

…Or: How I Learned to Stop Worrying and Love the Honing. (Dr. Strangelove has nothing on us.) :-D

Ok, this is a little longish, but there is no substantial way to provide a sharpening primer in a sound bite. I’ve tried to write about what will work well overall, without getting too focused on too many particulars in any sharpening media. No matter which way you choose to go ahead with sharpening, this advice should be helpful to you overall. It’s a reasonable primer that will put you on the road with usable sharpening skills. So grab a snack and a drink, and settle in for a bit. If you really want to learn to sharpen, reading this will likely be worth your time. Your Questions and Comments are invited as always!

When it comes to sharpening, abrasives are abrasives the world around. They may have particular idiosyncrasies you need to pay attention to, but they all abrade metal. Once you choose the abrasives you feel will work best for you, you will establish your own routine for working with them. All paths are means that will lead to a similar end. Waterstones, oilstones, ceramics, particulates, sandpaper, various styles of machine sharpening etc. The steel does not care; the abrasives don’t care either, as long as the grit equivilents of abrasiveness are appropriate to the goal. Sharpness.

For the sake of this discussion, I am referring to the abrasive grits, as they correspond to the grits common to waterstones. I do this simply for the reason that waterstones are very popular, but I am in no way advocating that waterstones are the best abrasive. Most all abrasives will sharpen, and it is up to the end user to investigate the pros and cons of the various abrasives to determine the best paths for themselves. For cross-reference please refer to this cross reference chart to derive the equivilent grit for the media you choose.

It is important to keep in mind that the goal of sharpness has stages.

Coarse grits are for grinding, heavy material removal, bevel forming, flattening. Initial flattening and bevel angle forming are the biggest jobs and to aid getting the job over with, the coarsest grits should be used to get the bulk of these tasks done.

Fine grits are for honing and polishing. Once you have established bevels and flatness on the backs, you will want to polish it. Removing coarse scratches in steel with finer ones is what creates finer sharpness. Sharpness actually is where the intersection of the two planes formed by the bevel and the back meet. The finer they are polished, the sharper they will be. the act of creating the wire or feather edge happens when the bevel side of the iron or blade is abraded until the dullness has been honed away. This is required to establish a fresh edge on the tool, and can be done with any number of the different honing or grinding grits.

It is up to the sharpener to determine how dull the tool is, and select the coarseness or fineness of abrasive grit needed to restore the edge to sharpness the fastest way. This means, it comes down to how much steel needs to be removed on the bevel side to form the wire, or feather. You must determine the condition of the edge, and the fastest way to restore it. If only a lttle honing is needed to restore the edge, don’t select coarse abrasives when you begin. If a lot of honing is needed, don’t select fine abrasives when you begin, but realize you will have to polish all the way up through the grits to the fine abrasives to restore the sharpness.

It is important to get a feel for the finish your honing equipment will give you as a finish result at each stage of the work. It will aid you to learn to evaluate what is needed, where to start, how long to hone, and when you have reached what was needed. Knowing this simplifies the task and helps you save time. This is experiential– it is learned by using the sharpening tools you have on your edge tools. It is getting to know one another. Call it sharpening intimacy if you will. Continue Reading »

The Utility of the Straightedge

Precision refers to the amount of dimensional accuracy or incremental refinement used when something is made, and can be attributed to the quality of the layout, workmanship, or machine set up.

Accuracy refers to the confirmation of dimensional tolerances.

Dimensional tolerances differ with the various types of projects a woodworker will commonly undertake. The set up of shop machines and precision hand tools often requires the precision of accuracy to be at the thousandth of an inch level, however most woodworking projects require accuracy at a level which is commonly referred to by fractions, and is often referred to in the 1/32nd (.031) to 1/64th (.016) range.

straightedge.jpg

The quality in our craftsmanship is inherent in our understanding of these constructs, and our personal stake in setting for ourselves, a level of tolerances. These tolerances are the differences between woodworking, and fine woodworking. Continue Reading »

The Woodworks Library

Amongst the many dilemmas facing the woodworker, just a few are what to build and how to build it, but even as those questions seem like early ones in the process, the earlier ones considered are even more elementary.

The nature and ways of wood, joinery, adhesives, and style are all things that need to be dealt with in the “what” to build and “how” to build it. Is it furniture, casework, cabinetry? Will it involve carpentry, as a built in as many elements of Arts and Crafts styling will? will it include some metal work or upholstery? Other leading questions like, will I have the appropriate tools, and can I properly fixture the work for all the different elements of construction? What finishes are most appropriate, and how best to apply them?

You see, it is a lot of questions. Fortunately there are a lot of answers. The art and craft of woodworking is age old, in fact, even our great grandparents and grandparents knew a lot about it, and lucky for us, even as much of an undertaking it was to publish books back in the day, the understandings of the woodworking trades, the methods and the how to with hand and power tools was something they authors of that period wrote about quite articulately. There was a want for future generations to know these things, and there was a lot they understood. Continue Reading »

Understanding Fractional Accuracy

Published by Rob under Metrology, Skill Development

I want to have that little talk with you about, Fractions. Yeah. But the plan is, if all goes well, that it won’t hurt – as much as it did last time. Working in sub inch territory usually involves the use of little buggers. The problem many people have when working with fractions, is that they relate the use of the common fraction to their math education experience when they were in school as children.

metrology3

Our school systems scared the bejeezus out of everyone by forcing us all to learn a series of mathematical exercises, which evolved around fractions that we would never use again in our entire lifetimes. For many, this often created mental blocks to the entire notion of fractions, even the simple useful ones, because after that harrowing experience, it seemed that nothing pleasant could possibly come from the manipulation of fractions at all. In fact, when people are faced with dealing with fractions, they generally feel some panic along with it. A panic that rates up there with the sound of high speed dental drills and root canals, and it is most likely from their harrowing experience in math class. Folks remember what all the wonky practice of solving mismatched fractions was really like, and relate that it was way, way too similar, and maybe even the diabolical preparation, for diagramming English sentences later on during their high school education.

I hope I can help make this a lot more user friendly! Continue Reading »

Using Cross Dowels

The big thing about using steel cross dowels for knock down construction is that your layout must be absolutely meticulous. I have, and continue to use these a lot in jig construction, but there are a lot of other great applications. cross_dowels.jpg

While a lot can be done with these, a common application is for use in workbench base construction. People move, many cannot build a bench with the certainty of knowing it will never need to be easily transported to elsewhere at some future point. This makes the use of steel or brass cross dowels a wonderful option.

Layout for cross dowels in knock down bench legs works like this. Continue Reading »
