Case-hardening is a method of giving surface strength to a specific material. Hardening can only take place under conditions where there is a carbon content in the steel. In the case of some wind turbines, the gear wheels are made of a special, low-carbon, chrome-nickel steel. After the teeth are machined, the gear wheels are packed into large boxes full of bone flour or some other form of high carbon-content powder. The boxes are placed in an oven and heated for about 24 hours to a red glowing temperature. During this baking process, some of the free carbon will be transferred from the surrounding carbon-rich powder in the boxes to the gear wheel teeth surfaces.
One day, I decided I needed an agenda. And instead of buying an agenda, I decided I would make my own. I did a layout, added a weekly Bible verse for a more personal touch, and printed it out. I followed this Instructables on how to bind a book. Made my own book cloth using this Vimeo video tutorial.
I suppose I could’ve bought book cloth, but I was told book cloth was expensive. I decided to look up the price for this post. First link I could find: Hollanders Linen Bookcloth Natural costs $4.75 for 18 by 25 inches. I can purchase 17 inch by 3.25 yards of Heat ‘n’ Bond Lite at Walmart or Joann’s for about $10 and I have fabric available.
I had the materials for the hard covers. I used canvas board that I had laying around for many, many years from when I thought I wanted to make miniature paintings for fun. I wrapped them with an old map of Suzhou and I have myself a couple, interesting covers.
I just used Mod Podge craft glue instead of Elmer’s glue or PVA. It seems to work fine, right now. The spine has been glued for about two weeks now and it’s gone through a fair bit of testing. I’ve been using it without the hard cover until now because I had to get the fabric washed before I could iron on the adhesive and paper backing.
I’m thinking the 2013 agenda will have anniversaries printed, too. Larger format? Flimsier cover? I have a year to decide.
I was reading an article on BlogTO about the Urban Design Streetscape Manual when I saw an advertisement for Winterlicious 2012. This year, Winterlicious will run from January 27 to February 9. Restaurants have been taking Prix Fixe reservations since January 12, so book your places now!
A couple years ago, I tried to put together a list of restaurants that offer vegan and vegetarian options for Summerlicious. It’s been a while since I revisited the ‘Licious menus and I noticed that the City of Toronto offers more informative restaurant listings.
