ADJUSTING FOR TIGHTNESS OF FIT
VARIABLE FINGER TEMPLATE
If the resulting joint is too loose, you will need to re-cut B2 with a different template guide to
tighten the joint. To do so:
1.
Make sure template is mounted with "B TAILS" label to the left.
2.
Mount a new second board (B2) with the same thickness as the board it is replacing.
3.
Use the same router bit (S3).
4.
Alternate template guides are included with the box joint accessory kit 77245 that enable
the user to adjust the tightness of joint when using the variable finger template. As a
reference, if only minor adjustments are percieved to be required, replace template guide
G3 with either G3.1 or G3.2. However, if a more significant adjustment is needed, use
G3.3, G3.4 or G3.5.
5.
Make the cut as described earlier in this chapter and then review the joint.
*
IF TOO LOOSE: Try another template guide that is higher up the chart (Fig. I20). For
example, if you used G3.2, you would want to use G3.3, G3.4 or G3.5.
*
IF TOO TIGHT: Try another template guide that is lower down the chart (Fig. I20).
For example, if you used G3.3, you would want to use G3.2 or G3.1.
MINI FINGER TEMPLATE
If the resulting joint is too loose, you will need to re-cut B1 with a different template guide to
tighten the joint. To do so:
1.
Mount template with "B PINS" label facing up and to the left.
2.
Mount a new first board (B1) with the same thickness as the board it is replacing.
3.
Use S0 router bit.
4.
Alternate template guides are included with the miniature box joint accessory kit 55165
that enable the user to adjust the tightness of joint when using the miniature finger
template. As a reference, if only minor adjustments are percieved to be required, replace
template guide G6 with either G6.1 or G6.2. However, if a more significant adjustment is
needed, use G6.3, G6.4 or G6.5.
*
IF TOO LOOSE: Try another template guide that is higher up the chart (Fig. I21). For
example, if you used G6.2, you would want to use G6.3, G6.4 or G6.5.
*
IF TOO TIGHT: Try another template guide that is lower down the chart (Fig. I21).
For example, if you used G6.3, you would want to use G6.2 or G6.1.
PROUD AND RECESSED JOINTS (ADJUSTING DEPTH OF CUT)
The depth of cut may need to be adjusted to correct proud or recessed joints.
PROUD JOINTS: If the end grain of either board is proud (i.e. is protruding over the other
board as shown in Fig. I22), then the depth of cut on that board needs to be shallower. When
the joint is proud, the bit should be raised (Fig. I24) to reduce the depth of cut accordingly
before re-cutting both boards.
RECESSED JOINTS: If the end grain on either board is recessed (or sunk below the other
board as shown in Fig. I23), then the cut on that board needs to be deeper. When the joint is
recessed, the bit should be lowered (Fig. I24) to increase the depth of cut accordingly before
re-cutting both boards.
