Jointer plane defined zoom I have using the jointer plane defined zoom as a paperweight since my results were so poor. Any hand plane must be adjusted before every use. But if you experience chatter or tearout as you are jointing, it is important to understand how to read the grain to minimize or eliminate the effect. When you pull it out of the other end of the wood jointer, it will be less warped. The direction that grain is running in your stock can affect the surface quality of your jointed edge. You can copy and paste the article onto a Microsoft Word Doc.

If an edge needs to be squared to a true 90 degrees for example, the front of a case which will have a face frame applied , a try plane with a cambered blade will actually make the process easier.

This process continues until the higher corner has been lowered sufficiently to make the edge square. On the other hand, when making a joint between two boards, one wants a flat edge for gluing. This is the purpose of the jointer plane. Jointed edges need not be a perfect 90 degrees if the two boards are match planed. When match planing, the show faces of the two boards to be joined are placed together and the Jointer Plane Defined Not Working mating edges are planed at the same time.

When planed together, the boards can be opened like a book and the angles of the edges will be complimentary to each other, resulting in a flat panel. Perfect 90 degree edges are not necessary. A cambered iron cannot make this joint as well as a straight iron.

Hopefully, this clears up some of the confusion surrounding the try plane. You can see now that a 7 and 8 can both actually make very nice try planes or jointer planes. It all comes down to how you set up the iron. Tag: Hand Planes. I'm a passionate woodworking enthusiast of over 30 years, with an interest in the methods of pre-industrial joiners and cabinetmakers. I'm a furniture maker, teacher, and author, and I share my thoughts and experiences with the goal of educating and inspiring others who are pursuing the craft of traditional woodworking.

In addition to writing about and teaching traditional woodworking, I also build commission pieces for customers, and speak at woodworking shows and seminars. Just picked up an old try plane. Only problem I had in the 5 minutes I tried, is setting up that two part blade and the wedge.

Should be fun! This site uses Akismet to reduce spam. Learn how your comment data is processed. Remember Me. Not a member yet? Register now. Sign me up for the newsletter! The camber on the blade of the try plane is less than that of the jack plane so that it will remove the deeper scallops left by the jack plane, and bring the surface closer to flat. Bob Rozaieski.

A masterful and concise dissertation. This cutter head is typically driven by an electric induction motor. Older machines were driven by belts from line shafts.

A moveable fence is normally set perpendicular to the tables, though some models may allow settings adjustments to various angles.

These tables are referred to as the infeed and outfeed , the table from which the work piece is fed into the machine and the height reference table on which the work piece is floated over lightly as leaves the machine's cutting head. The work piece to be planed flat is placed on the infeed table and passed over the cutter head to the outfeed table, with care taken to maintain a constant feed speed and downward pressure.

The cutter head contains two or more knives which are honed to a very sharp edge. The knives are arranged radially in the cylindrical cutter head such that their cutting edges protrude from the cutter head so that they will come into contact with the board being cut as the cutter head spins. The cutter head's axis of rotation is parallel to the table surfaces and perpendicular to the feed direction.

The knives cut into the board in the direction opposite to the feed. Some, more expensive, jointer models contain a spiral, or helical, cutting head. This configuration has many individually mounted, self-indexing knives that can be rotated to a new edge when necessary. Other, older, models have cutter heads that are not cylindrical but instead square. This leaves a significantly larger open region below the level of the blade edges and creates a larger hazard as hands, etc.

The infeed and outfeed tables can be raised or lowered independently of each other and in relation to the cutter head although the outfeed table is normally set so that it is level with the knives when at the top dead centre of the rotation of the cutter head.

The infeed table is adjusted so that it is lower than the outfeed table and this gives the depth of cut. Jointers for home workshops usually have a 4—6 inch —mm width of cut.

Larger machines, often 8—16 inches —mm , are used in industrial settings. In operation, the board to be jointed is held with its face against the fence and the edge to be jointed resting on the infeed table. The board is fed across the cutter head and onto the outfeed table. The knives in the revolving cutter head remove an amount of material and the relationship of the two tables and the fence keeps the board oriented in such a way that the result is an edge which is flat along its length and perpendicular to the board's face.

A jointer may also be used to flatten the face of a board, in which case the sole focus is to produce a flat surface on the face of the board and the fence is not used. This procedure is often performed prior to edge jointing so that the board has a flat reference face for subsequent operations. To straighten a piece of bowed timber, the guard is temporarily swung out of the way.

The machine is switched on and the timber is slowly lowered to the machine table, with the concave side down. A few cuts are made out of the red section "A". The timber is turned end for end and the same procedure is done to the section "B". This is repeated as required with the operator sighting along the length of the timber from time to time to check on straightness of the timber.

When the timber is almost straight, the guard is replaced and the last cut is made in the normal way. Twisted material is treated in a similar way. The operator lays the timber on the bed of the machine and rocks it slowly from side to side to estimate the amount of twist. If there is, say, 20mm of twist in the board, he holds the board level and takes 10mm off one end, then repeats it for the other end.

Jointers are also used for making rebates also known as rabbets in North America in finished timber. The fence is set to the width of the rebate and the infeed table is set to the depth. A jointer that is used for rebating has the outside ends of its blades also sharpened and set with a small clearance from the cutter head.
