Class Machines

I prepare the stock for my projects in the adult ed class I take at a local high school. The equipment is decent, although the upkeep could be better. Last fall both the jointer and planer were out of commission for several weeks. Given that the use of those machines and the tablesaw are the reason I take this class, it was frustrating to say the least.

I first took this class about 10 years ago, after winning a gift certificate in a raffle which was part of the annual charity fund raising at work. I've taken it at least one session almost every year since.

Pictured below are the machines I use most often at class, and a brief explanation of each. This is the jointer. It's used to create a flat face, or edge on a board. Step one in surfacing a board is to place it on it's face on the table to the right of the red guard. The table surface on the right is slightly lower than the table surface on the left. The blades are under the red guard attached to a cylindrical holder. The blades spin and as you push the board from right to left they shave a small amount off the wood. Once one face is flat, the board is held on edge against the fence (the vertical metal piece in the picture), and run over the blade. As long as the fence has been set at a 90 degree angle to the table this will create an edge square to the face.

This is the planer. This one is mammoth - it'll take a board at least 20" wide. The planer is used to create a second flat face parallel to the face created on the jointer. It works similarly to the jointer. In the planer the blades are suspended above the board, and slice the wood off the top face of the board. The planer also has rollers flanking the blades that feed the board through.
This beauty is the table saw. I didn't manage to get a picture that shows the blade (sorry about that). Using the fence (the T shaped item on top of the table) and a miter gauge, which runs along the cut out at the left side of the table, the wood is cut to size.

wow this is heavy duty stuff. I'm going to have to google some of this stuff. I have never heard of jointing thing, I still can't picture what that means. And 'flat face' is hard to imagine too.
Thanks for sharing this stuff, it opens up my mind to whats out there that I otherwise wouldn't have heard of.
