What should you do before starting the jointer?
Make sure fences and any other guards are in place before using the machine. Remove all wrenches and tools used in the set up from the table. Provide a minimum clearance of at least 1 m (3 ft) greater than the length of the longest stock being worked.
What are 5 safety rules for a jointer?
The following is a list of safety precautions to take into account when operating a jointer. Always read and follow the manufacturer’s instructions. Wear ear and eye protection, and do not wear jewelry, long sleeves, or loose clothing. Use paddles, push blocks, and push sticks to keep your hands 6 in.
What is the main use of the jointer?
The jointer derives its name from its primary function of producing flat edges on boards prior to joining them edge-to-edge to produce wider boards. The use of this term probably arises from the name of a type of hand plane, the jointer plane, which is also used primarily for this purpose.
What should you never pass over jointer?
Safety Rules Hearing protection advised. Always run dust collection with jointer. Keep hands 4” away from cutter head. Never pass hands over cutter head.
What is the most common injury on a jointer?
Second to circular saws, hand-feed jointers or surface planers are the most dangerous woodworking machines. Most injuries are caused by the hands and fingers of the operator coming in contact with the blades of the machine.
How much should a jointer take off?
Again, the maximum cut will depend on the width and density of the workpiece, but I generally don’t remove more than about 1⁄8″ at a time. For pieces that aren’t much longer than your infeed table, hook your heeled pushblock onto the trailing end of the board.
What causes kickback on a jointer?
A board or piece of one, resting on top of the cutter head will experience a force moving it to the operator’s right. If that force is unopposed by the operator adequately pressing the board down and to the left, the board may be thrown to the right. This motion is known as “kickback”.
Where is the danger zone when working on a jointer?
Danger Zone-The jointer danger zone is 3″ out from the cutterhead and knives and 8′ directly in front of the cutterhead. When you use the jointer, stand to the left of the machine (opposite the drive shaft) and keep your hands away from the knives. Always wear proper eye and ear protection.
When using the jointer you should stand?
Stand on the left, beside the jointer, not behind or in line with your material. You will have more control over your material, will not have to reach so far, and will not be hit by the material if it is thrown from the machine. 11. Shift your hands so they never pass over the knife head at any time.
Why is my jointer not cutting flat?
In some cases, this can be caused by infeed and outfeed tables that aren’t parallel. But a more common (and easier to fix) cause is an outfeed table that is just a bit higher than the jointer knives.
Can you plane with a jointer?
It does exactly what a hand plane does, except that you move the wood across it instead of moving it across the wood. A jointer creates a flat surface on wood, and yes, it can be used to correct bow and warp on one side of a board at a time.
Do you really need a jointer?
Simply purchase your lumber already milled in S3S or S4S form (surfaced on three sides or surfaced on 4 sides). If you’re at a point in your woodworking where you’re starting to use rough sawn lumber, say from a lumber mill or your local sawyer, then a jointer is absolutely essential to your shop workflow.
Who invented the jointer?
As covered in Early History of Jointers, the modern jointer was patented by Climer and Riley in 1866. Before that, many attempts were made to produce an effective machine to flatten the faces of boards. The earliest woodworking machines were sawmills that reduced a log to rough-sawn boards.
Where do you apply pressure on a jointer?
The idea is to remove material only at the ends where the board is touching the jointer. It’s even easier in this situation to press the board flat as you move it across the jointer. So it’s important to only apply pressure on the ends.
What is a good size jointer?
An 8-inch wide jointer allows me to joint wider boards than a 6-inch jointer, and 8-inch jointers usually come with longer infeed and outfeed beds, adding more support to the lumber. And 8-inch jointers are usually affordable enough for hobbyist woodworking shops.
Does a jointer straighten boards?
Wood Jointer—The Easy Way to Make Square and Flat Board Surfaces. A jointer quickly smooths and flattens the edge of a board while cutting it square to an adjacent edge. Once this is done, the board is ready to lie flat against a table saw fence or table for a straight cut.
When using the table saw you should?
Stand to one side of the saw blade when cutting; do not allow others to stand in direct line with the saw blade while the saw is operating. Use the blade guard that comes with the saw. Never reach over the saw blade to remove or hold down the piece of wood. Always use a push stick when ripping wood on your saw.
When using the jointer you should joint with the grain?
To get a jointed edge that’s square to the face of a board, you should joint the face first. Then, with the newly jointed face against the fence (with the grain running downhill), joint one edge square with it.
