Picture it: eight people with different skill levels, each trying to design a different project (which, by the way, they have no idea how to do) and hopefully cutting some wood by the third class. Meanwhile, the instructor is running from student to student, and then running to the table saw where a kickback has occurred. It is no wonder that at the end of the class not a single thing has been made and most of the students don't come back.
And with many homes falling into the “contemporary but traditional’ style that has taken over the decade, these wine racks are in high demand and can fetch a pretty penny for even a more simplistic design.Feel free to get creative with the design for some more bargaining power. And for a design to hold a small number of bottles, you can expect up to $50 per unit sold.
Tightening the nuts clamps the uprights against the shelves, holding them in place and providing shear strength (through friction) for the whole assembly. I know of an 8' tall, 12' long version of these shelves that has survived a few minor earthquakes while fully loaded with hundreds of books. Once the nuts are tightened on my smaller versions, I (all 240lbs of me) have a very hard time "racking" the shelves by pushing on one end of them in an attempt to get them to collapse: I can't.
Thickness planer. A thickness planer is used to fix surfaces of imperfect wood. If you are picking up less than perfect wood from the lumberyard, wood with some surface defects, a planer will let you fix that wood in the quickest time. A thickness planer pays for itself quick as it allows you to buy cheaper wood that doesn’t have perfect surfaces and fix it yourself. Be careful though. You loose wood during planing. So the remaining amount of wood still has to be worth the price you paid for it.
