Always be on the lookout for usable wood. You might be able to salvage some. You can use a metal detector to find nails and screws. You don’t need a full fledged metal detector. I use a pinpointer made by Garrett. If your wood has some woodboring beetles you can still use it if not eaten too badly. A healthy dose of cyfluthrin will take care of them.
Framing is another part of carpentry. Framing takes skill and experience it’s not a part of carpentry that anyone can just jump into. The skills that are required in framing is plumbing up a wall, make sure studs are 16 on center or whatever the specs calls for. Developing a good eye for straightness in carpentry work. Last but not least making sure everything is level.
For someone just beginning to purchase hardwood lumber, lumber grades can be overwhelming. Most lumber companies use the generally accepted grading rules set by the National Hardwood Lumber Association. Grades are based on the amount of usable clear material in a board. The highest grade boards are FAS and Select, followed by #1 Common and #2 Common. What grade you choose depends on your project. Some projects, such as tabletops and high quality furniture, may dictate the highest grade available. Many other projects are just as easily adapted to #1 Common (often referred to as cabinet grade) – kitchen cabinet doors, smaller projects and items where some character is acceptable.
I've found that it is easiest to attach the shelf by attaching the 2×2 side rails prior to connecting it to the table. To do this you'll sort of take a minor step back by removing the two lower 2×2 side rails (only 8 screws). Then drill the shelf to the 2×2's as shown below. Lift the shelf into place and attach each end of the shelf to the lower end rails using 2 1/2″ Kreg Screws. Once that is secure flip the table right side up and add the cross supports.
Your moisture meter should have settings on it that will account for different species of wood. For instance, oak is a hardwood, but ebony is an even harder density wood. If you are planning an inlay job using both types of wood, you will need to know the moisture content levels of each of the two species so that your inlay glue joints will stay intact. These different wood species have different specific gravities, which must be used or programmed into the moisture meter.
The sequence in which boards are cut from a log will determine how stable the boards will be once they dry. As a board loses moisture it will shrink in three dimensions. The change in length is so small as to be considered insignificant and the change in radial movement is always less than the tangential movement. This is most significant as the wood dries between the time it's cut (i.e. green wood), and the point where it is kiln dried or air dried and ready for use. Wood that shrinks excessively, or that has been dried improperly, will often develop checks at the ends. When shopping for lumber, carefully inspect the ends for any checking, or for excessively long checks. It is best to allow for some scrap at the end of each board, just in case. As you trim the end, hit the off-cut across the edge of your bench, and if it breaks in two, you'll have to cut off a little more.
I built my coffee table!! I used the plans at www. EasyWoodwork.org to build mine – highly recommended you check those out too. They are detailed and super easy to read and understand unlike several others I found online. The amount of plans there is mind-boggling… there’s like 16,000 plans or something like that for tons of different projects. Definitely enough to keep me busy with projects for many more years to come haha
