The common file, as every workman knows, is an Implement, the flat or curved surfaces of which are notched or serrated in such a manner that, on being rubbed on the wood, ivory, metal, or other hard substance for which the tool is intended, a surface of more or less smoothness is obtained.
Files are made of bars of steel prepared in a peculiar manner, it being necessary that the file should be formed of the hardest possible metal, or else its working surface would be speedily worn away. The steel is therefore rendered harder than usual by means of a process known as double conversion, the metal thus prepared being said to be doubly converted. (more…)
Next week, Lost Art Press titles that I’ve written will feature a new design of signature bookplate.
Designed and printed by Brian Stupayrk at Steam Whistle Letterpress & Design, these bookplates are printed in two colors on Crane & Co. self-adhesive paper.
If you purchased one of our books from another retailer and would like one of these bookplates, you can order one in our store here.
Many of the woodworking “gift guides” out there are a thinly veiled attempt to get you to buy some new products that are new to the store and are new, new, new.
As someone who was force-fed a diet of new tools for 15 years, here is my advice: Be wary of tools that are new in the marketplace. Let the manufacturer work out the bugs in the manufacturing process first. This advice carries over to new car models etc.
Case-in-point: A few years ago one of the big woodworking retailers came out with some 90° clamping blocks that you would clamp to the inside of a carcase to square it up. This new product was out just in time for Christmas and was in all the company’s gift guides.
But here was the problem: All of the clamping blocks were made at 89°.
Over at my other blog at Popular Woodworking Magazine, I’ve been doing a series called “The Anarchist’s Gift Guide.” These are small, time-tested and thoughtful gifts that you might actually use. I have no financial interest in any of the products. They are simply little things I have purchased and used for years in my shop. Here are the links:
Day 1 is here. Rockler Mini Drill Bit Set
Day 2 is here. Brownell’s gunsmith drill bits
Day 3 is here. Grip mini pry bar
Day 4 is here. Tiger Flakes
Day 5 is here. Gramercy Holdfasts
Day 6 is here. Draft-Matic mechanical pencils
I have a couple more to add this week. But today I am taking a day off to go to Chicago and eat myself silly.
A few naughty readers have been attempting to build collapsible tables and bookcases similar to ones I’ve been constructing for “Campaign Furniture” and have run into some trouble.
Instead of being a wiener-kabob and saying “wait for the book,” here is some basic but critical information about mechanical furniture: In these simple constructions, the pivot points have to be equidistant.
What does that mean? Take a look at the quick-and-dirty sketch above. In these bookcases, the center pivot point is on the outside of the bookcase. The top pivot point it 7-1/4” above that — right below the top shelf. The lower pivot point is 7-1/4” below that right above the lower shelf.
If the upper and lower points are not equidistant from the center, the bookcase will not fold flat. Also good to know: If the distance between the lower and upper pivot points is greater than the length of one of the shelves, the bookcase will not fully collapse. The two center pivot points will run into one another.
I am almost finished building this bookcase and will post a movie later this week.
In your laſt acceptable Letter dated from Weſtminſter the 2d. of Auguſt, I obſerve that you deſire me to turn my Speculations, and to give you my Thoughts upon ſeveral Appearances relating to a Razor; particularly to ſay ſomething concerning its Edge and Sharpneſs, which in a good Razor is ſo fine and ſo nice, that it is ſubject to the leaſt Change and Alteration in the Weather; and particularly that Cold has ſuch an Influence upon it, as to ſpoil and blunt its Edge, inſomuch that it will hardly cut a Hair aſunder.
In anſwer to your ſaid Letter, I muſt acquaint you, Sir, that I ſhave my ſelf, and that my Razor, which I always uſe twice a Week, and which I have had above Thirty Six Years, was never Ground but twice, and yet it cuts very well; but I ſet it ſometimes upon an Oyl-ſtone or Hone, yet not as I obſerve ſome Barbers do, who ſtroke it above Twenty five Times on one ſide, and then again as many on the other; whereas I on the contrary paſs my Razor once only on one ſide, and that very gently with the Edge againſt the Stone, and then on the other ſide in the ſame manner; and ſo continue about ten or twelve Times; after that I paſs the Razor, with the Back of it downwards, upon a Leather prepar’d with Tripoly [which the Silver-ſmiths uſe, to Poliſh or Clean their Plate with.]
When I look upon ſuch a Razor thro’ my Microſcope, I ſtand amazed at the great number of Gaps and Notches that I ſee in the Edge thereof, and wonder how one can ſhave ones ſelf ſo ſoftly therewith; nor does my Razor refuſe to do me Service even in Winter and cold Weather, tho’ I muſt own at ſuch times the Shaving is a little more painful, but that I have hitherto thought, was only occaſion’d by the Hair of the Beard being harder in Winter than Summer, when ’tis cold Weather I always keep my Razor in a Room that has Fire in it.
