6-13 For mortises and tenons shorter than the guide, reverse the
calculation: Guide, minus Joint, divided by 2.
Example: you may want a 1"[25mm] joint
➀
using 2"[50mm] guide
➁
.
So, 2" - 1"
÷ 2 =
1
⁄2 [50mm - 25mm ÷ 2 = 12,5mm].
Make a block
1
⁄2"[12,5mm]. You will also need a short length of
3
⁄16"[5mm] dowel
➂
to act as a guard when routing the mortises.

6-14 Tenons Setting the block and limit stops for the shorter
tenons procedure
➀➁
is exactly the same as for longer tenons
setup, except when you come to rout.
