I usually mill my own stock, 50 to board feet Rough Lumber Projects Quizlet of rough lumber at a time. The process begins with my trip to the lumberyard. I take rough cut lumber projects pdf time to pick stock that has the least cup, bow and twist.
My strategy is not to completely avoid all defects, as that would be too costly. Instead, I work with deformed stock that my shop set-up can handle efficiently.
It is good advice to mill only the stock that you need for a project. The trade-off, however, is reduced efficiency, as you have to repeat the machine set-up rough cut lumber projects pdf every small milling job. Rough cut lumber projects pdf prefer to mill my rough lumber in bulk, preparing enough for several projects. For edge-jointing, I use my table saw. The only other machine I need to mill my wood is a thickness planer.
First, I sort all the boards into groups according eough their rough thickness boards that are too long can be crosscut to more manageable lengths and condition twisted, bowed or cupped. By milling boards of similar thickness and condition as a group, you rougn to make fewer machine adjustments. When it comes to defective lumber, twisted boards are the more difficult ones to handle.
Mildly cupped boards, for example, can usually be dressed using the thickness planer alone. Twisted lumber, however, is a challenge whether using a jointer or a thickness planer because it rocks as you feed it into the machine. The trick is to stabilize a twisted board with an aid before you flatten it. One such example is the simple planing sled, made of a flat, rigid sheet good with a top cleat attached to one end.
This sled supports a warped board with shims under the high spots. More sophisticated sleds rough cut lumber projects pdf be designed and built that allow you to back up rugh board with adjustable supports instead of shims. Right: This planer sled uses rows of support blocks that can be raised or lowered to level the lumber. Photo by Kelly Miciak. To use the planing sled, butt the twisted board against the cleat in the proper grain direction and place shims to fit underneath the gaps.
Next place the sled, cleat end first, ccut the infeed table odf feed the whole sled through the planer. The cleat will keep the infeed rollers from pushing the stock ahead of the sled.
Left: Squeeze blobs of hot-melt glue to attach the shims to both the board and the rough cut lumber projects pdf. After one face lunber rough cut lumber projects pdf, remove the board from the sled. Turn the board over and continue milling the second face. In shops with extreme humidity swings, leave excess wood to allow final milling in case some warping sets in after leaving the boards to rest for a couple of days.
Left: After flattening the first face, remove the board from the sled and mill the opposite face. Right: Try to take off an equal amount of stock from each face to minimize warping when the tension is released. My Remedies Snipe scoop-like depression occurs when the workpiece is not properly supported as it is fed through the planer. Not all machines are made the same, and I recommend investing in a thickness planer that has a carriage lock feature for better snipe control.
The simplest snipe solution, but one that is also wasteful, is to let the snipe happen and then cut off the ends. When using this method, wait to cut off any rough or checked ends promects the board is planed. With a planer and a simple planing rough cut lumber projects pdf, you can mill your own stock and rough cut lumber projects pdf the rewards of using rough lumber, one of which is the pride of completing a project from rough to finished.

No Jointer? Right: Once the glue sets, run the sled with the board through the planer. Left: Look for the carriage lock feature when you consider buying a bench-top planer. Right: Cut off the rough ends with any snipe after the faces are dimensioned. It may also help to keep the ends from teetering up into the cutter blades by lifting the back end of the board as you run it through the planer and lifting the front end just as the board is about to leave the planer.
Feed the Boards Through at a Slight Angle Feed a long board through the planer at an angle so the cutter head makes contact with just the corners of the board. Text and photos by Charles Mak Charles Mak, now in retirement, is an enthusiastic hobby woodworker, teacher, writer and tipster.
