My plate is clean: Final Clean Plate Sneak Peak

Turning you on: An (over) simplified process for using a lathe
Step 1) Cut a length of wood that is straight and square on the ends. If it isn't square when you start the lathe, you'll cause yourself irritation and potential eye injury trying to get it centered. If you've ever done ceramics, this process is very similar to centering the mound of clay on the wheel, except that if you don't do it right, you can't just remound the material - you'll waste an expensive piece of wood a tree died to give you. You might not think it, but the harder the wood, the easier it is too turn; soft wood chips and tears more easily, perhaps because the grain/wood fibers are not as tightly bound to one another. Generally, harder woods (maple, walnut, cherry) are much more expensive than softer woods (pine). Actually, come to think of it, perhaps leafy tree wood is softer than coniferous wood - something to think about at a later date... back to getting lathed:
(Step 3) For my project, I was cutting spindles, but wanted to keep the ends of each square, so I cut a very shallow groove around the perimeter of the wood, about 1 1/2" from each end (see photo). If I hadn't done this, I likely would have splintered off a chunk on each end; cutting the groove helps keep the ends square. If you're going to turn the entire length of wood, this wouldn't be necessary.
I should mention I've been doing this for a while now, but am nowhere near a pro. There are people who do this - and only this - type of woodworking as a passion, and produce some amazing things. With the exception of Christmas ornaments and baby rattles, turning is something I usually incorporate into a larger piece, rather than make as stand alone objects. If you want to see cool pictures of way better turnings, or learn more about the process, check out the Loess Hills Woodturners Club, a local club based out of Iowa. Of for more photos, check out the American Association of Woodturners.

Getting Lathed: A new project

It's all in the cut
For a very long time I had assumed that I knew what "quarter sawn" lumber was. I thought this meant that the wood was milled in exact quarter dimensions, such as 2/4, 3/4, 4/4, etc. I also thought this "style" of cut was sort of the opposite of dimensional lumber, such as one-by-fours and two-by-fours (which are actually only 3/4" and 1 1/2" thick).
However, I just stumbled on a great little article, which includes simple explanatory drawings, that highlights the difference... it's all in the cut...http://www.allwoodwork.com/article/woodwork/plainorquartersawn.htm

Clean Plate table sneak peak
Most of my weekend was in fact spent on my back screwing... boards that is. I took advantage of an extra day off work to finish fabricating the first part of the Clean Plate table. I affixed the side rails to the 4 gorgeous solid walnut legs and created a sort of interior skeletal structure from poplar (a very straight-grained, durable wood).
I joined enough planks to create a full top that screws onto the structure from the underside of the table. In the picture at right, I'm using bar clamps to join the pieces laterally, and squeeze clamps to keep the board from buckling upward under the immense pressure of the clamping. This will also ensure that the piece will remain a flat surface after the glue dries.
Drilling up through the poplar structure into the underside of the planks will accommodate any expansion or contraction that may result from changes in temperature and humidity; this also makes the top look like it's resting on the legs and side rails, without any fasteners, which is a "cleaner" look.
The next phase will involve a pretty extensive amount of sanding on the top. This is the part of working with wood that I wish I didn't have to do. Not only is it hard, tiring work; it's also very dirty and not particularly good for one's health. I wear a professional respirator (those paper masks are worthless, btw), but still come home with nostrels full of brown dust and my eyes feeling slightly irrirated, like I'm wearing contact lenses that are past their expiration date. It's worth the work and risk to health - check out the contrast in the richness of the section of wood that has been sanded and coated with linseed oil and the section that has not - it's pretty dramatic and makes me excited to see how the top will look when finished. Hopefully that happens by the end of the week. Time is running short... Elle starts the move-in to Empty Room August 1.
