Festool DF 500 사용자 설명서

Generally miter box joints are fairly weak because the joint is 

predominately endgrain to endgrain. Tenons significantly 

increase the strength of the joint and make it easier to 

assemble and clamp the pieces.

► 

For thinner materials, keep the mortise close to the inside 

corner. This minimizes the chances for boring all the way 

through the workpiece. 

► 

For very thin materials, it may be necessary to shorten the 

► 

For thicker materials, stacked mortises can be used as 

shown in the picture to the right. 

 

1. 

Tilt the fence to the appropriate angle. (Refer to the table 

2. 

Lower the fence to the desired height. Note that the 

mortise should be close to the inside corner to avoid 

penetrating through the workpiece. 

3. 

Plunge the joiner as shown below.  

► 

The stacked mortises are used for thicker stock. 

► 

Grasp the joiner by the auxiliary handle for best control. 

 

 

A locked tenon joint is any type of joint with two or more 

tenons at opposing angles. Once the opposing tenon(s) are 

inserted, the joint cannot be disassembled. With the 

exception of the Three-way Locked Miter Joint (page 18) at 

after the joint is assembled. This is referred to as the Locking 

Tenon. 
There are many variations of a locked tenon joint, but the 

simplest involve a mitered corner in a box or flat frame. The 

miter angle provides an easy reference for the two tenon 

angles. 
In the example shown to the right, a standard miter joint is 

constructed using a large Domino tenon for strength in the 

main joint. The locking tenon is a 5mm x 30mm Domino 

tenon.  
The mortise for the locking tenon is milled with the joiner’s 

plunge depth set to 28mm. This mortise is typically milled 

after the joint is assembled, but it is possible to mill the 

mortise in each piece separately.
