Refer to the events calendar for the list of upcoming trainings, and feel free to post in the #help-woodworking slack channel with any questions about training.
Training Checklist
- When to use a jointer and basic principles
- Making your first flat face
- The dangerous spinning bits, kickback, blade guard.
- Knowing when your face is flat
- Cover everything in Operation section
- Instructor demo proper technique of setting up machine and pushing a block of wood through the jointer.
- Trainee demonstrates technique of using the machine
- Trainers: Sign off trainee using the Slack command /membership > equipment authorization.
Operation
Be familiar with and abide by the woodshop rules.
Setup
- Turn on the dust collector and ensure the blast gate is open and the machine is getting suction
- Ensure your material is free of any metal
- Metal going over the cutter head will damage the teeth
- Check your grain direction to determine the best feed direction
- Assess the shape of the board to determine which face you will joint
- Bowed boards should be placed with the convex side up
Usage
-
Start the jointer and let it reach full speed before beginning to cut.
-
Hold the wood firmly against the fence and push it over the cutter head, applying steady and even pressure.
-
Use three directions of force to push wood through. Through the cutter head, towards the fence, and light downward pressure. Using push blocks for downward force is REQUIRED at denhac! Push blocks mitigate the common accident of kickback shooting wood back and fingers pushing wood down going into the spinning blade.
-
Never reach over the cutter head or try to pull the wood through.
- Push your material all the way through the cutter head until the guard swings back into place.
- Never move the guard with anything other than a piece of material that you are actively jointing.
-
Shut off the jointer and wait for the cutter head to stop spinning before grabbing your material and cleaning up any chips on the jointer bed.
Shutdown & Cleanup
Materials
denhac’s jointer can handle material up to 6” wide. For boards wider than 6” (but narrower than 20”), we recommend using the planer and a planer sled to joint your material. Ensure your material is free of any metals using the metal detector prior to making your cut. Softer materials can be fed through the cutter head at higher rates than harder materials. Slower feed rates will typically give better results.
