While I mostly use the sector for doing design and layout work in my shop, I realized recently that it’s also a great tool for showing someone (especially your kids) an intuitive approach to understanding fractions. Here’s how I’d describe what’s going on in the drawing above:
Because I want to find out where a point four-sevenths of the width of a board would come to, I set the legs of the sector to touch each edge of the board to denominate (i.e. to name) the kind of divisions I’m looking for. Here, that would be seven – the denominator. Now I want to enumerate (i.e. give a number) to how many of those sevens I’m looking for – in this case the numerator is four. The job of the dividers is to grab this numerator above the denominator value on the legs of the sector in order to transfer the setting to the face of the board. For me (and my kid), this drawing offers a decent visualization of why the numerator goes over the denominator. You can learn more about the sector in excruciating detail in “By Hand and Eye;” and in a somewhat less excruciating matter in “By Hound and Eye.”
Good morning! Another weekend over and another busy week is upon us. No matter how crazy life is, make sure to take some time to read the forum and see what your fellow woodworkers are up to. Remember, if you have a question about our products, procedures in our books or anything related to Lost Art Press, the fastest way to get an answer is our forum. Check it out here.
No. 7 Adjustment Issues Kendall took apart his Lie-Nielsen No. 7. to sharpen the blade but now that he is putting it back together he cannot get the blade to adjust below the sole. He is looking for any help on what he may be doing wrong. Let’s see if we can prevent him from having to make a call into Lie-Nielsen. Help him here.
Handworks 2017 Does anyone who has attended Handworks have a recommendation for a place to stay? Steve is ready to get his plans together and is looking for input.
Spare Bedroom Workshop Mark and his girlfriend have found a house that they love and want to buy but there is no garage or basement to use as a workshop. Mark is looking for feedback from anyone who has used a spare bedroom as a shop before. Did it work out? How was the noise? Was dust all over the house?
Crucible Dividers Jason likes the pictures of the Crucible dividers but wants to get to the point and find out how they work. If you have a pair, let him know what you think.
Hot Hide Glue Gelling Quickly Josh has had success with hot hide glue on small pieces but has had no success with it when trying to glue up a panel. Every time he finds he is unable to close the joint. He is wondering if anyone would be able to help with why this is occurring.
Staked Chair Travis has made a pair of staked chairs from “The Anarchist’s Design Book” and they turned out great. (Photo at top and to right.) The beveled edges are a great touch!
Bookshelves that fold at or disassemble are common items among surviving pieces of campaign furniture. These ingenious units were generally pretty small. After all, it’s not as if you were traveling overseas with a Carnegie library, and books of the 19th century were usually compact items.
How small? A typical campaign shelf unit is 3′ wide, 2′ high and 8″ to 10″ deep. That’s not a lot of shelf space.
Many of these shelving units were designed to sit on top of another piece of furniture, such as a campaign chest or desktop. Or they were intended to hang on the wall, which was especially handy during a sea voyage.
Common Types of Portable Shelves The most common type of portable shelf isn’t one you’d expect to see in a book on woodworking because it’s mostly metal. These shelves are tubular metal uprights that screw together with two, or usually three, wooden shelves between.
These shelves look spindly but are robust enough for the job.
A less-common variant on these shelves replaces the metal with wooden uprights – usually turned spindles – that screw together with the wooden shelves to produce the finished piece.
Another type of shelving unit is a folding book rack. The simplest form of book rack has a at shelf with two “bookends” that fold flat while traveling. These simple racks are not exclusive to the campaign style; you’ll find variants during every furniture period where books were common.
The ends of the three boards are mitered and hinged. Sometimes the ends have handles so you can lift and move the loaded rack.
There are more complex mechanical book racks that also expand in length as well as having folding ends. These usually require some tricky hardware to make them function well, so I decided not to build one for this book.
The third common type of collapsible shelving unit folds like an accordion. You usually remove a center shelf (or two), and the uprights fold in on themselves, turning your shelf unit into a flat pile of lumber. The first time you see it in action, it’s actually a little bewildering. But it is quite cool.
This type of shelf unit requires no special hardware – just a small pile of butt hinges. And there is almost no real joinery to speak of. So it’s an ideal project for the woodworker without access to a forge or a metal shop.
These accordion-style shelves came in several dierent sizes and configurations that were embellished or plain. Some versions were designed to hang on a wall; others sat on top of a chest or desk.
The shelves I built for this book are based on a unit I admired in one of the Christopher Clarke Antiques catalogs. The original was made from teak; mine is mahogany. While the only joinery in the whole project is cutting two dados, you will become quite an expert at installing butt hinges. It takes 12 hinges to get the whole thing to work. And installing the hinges precisely makes the shelf unit sturdier and makes it collapse more smoothly.
For the most part, facsimile editions of historical books don’t do much for me. The printing is muddy. The paper is a measly notch above groundwood (aka newsprint). And the binding is weak. The cover, however, always looks nice so as to trick you into buying the poor manufacturing job within.
If you’ve ever bought a facsimile of Thomas Chippendale’s famous book, then you know what I’m talking about. Some companies do a good job with facsimiles; most do not.
So when we decided to reprint the “Stanley Catalogue No. 34,” we wanted to reproduce the look and feel of the original and make some manufacturing improvements, such as a sewn binding, to ensure our version could outlast floods, dogs and babies.
Our first shipment of “Stanley Catalogue No. 34” arrived smack dab in the middle of Woodworking in America, and I haven’t had much time to look at it. (I had one in the car that I was examining at stoplights; that’s how nuts it has been here.)
So I’m happy to report that this book has exceeded every expectation I had for it. The prepress people managed to make plates that mimicked the original’s crisp drawings and text. The black are black. The screens are real screens – not some moire mess.
Our warehouse is getting an assembly line together during the next week to ship out all the pre-publication orders. So if you placed an order for one, it will be on its way soon.
“Stanley Catalogue No. 34” is $25, which includes shipping in the United States and Canada. Many of our retailers have decided to carry the book, including Lee Valley Tools, Lie-Nielsen Toolworks, Henry Eckert in Australia, Tools for Working Wood in Brooklyn and Classic Hand Tools in the UK. Check out our international ordering page for links.
You can now visit crucibletool.com, and read up on our holdfasts, our new dividers and why we started this company. I’ll be adding a lot more blog entries in the coming week, including:
How to retrofit a benchtop to use 1”-diameter holdfast holes.
How to carefully ream holdfast holes for a sweet fit with the tool’s shaft.
A tour of Chris Erhart Foundry, where our holdfasts are poured.
An update on the next batch of dividers.
Note that we are not taking backorders for the dividers. To prevent us from getting into a bad situation that plagues many young businesses, we have decided to sell only what we have in stock. No backorders. No waiting lists.
When we have stock, we will announce in advance when the dividers will go up on the site so everyone has a fair shot. And we think we’ll soon have enough to keep them in continuous stock.
