10 Cut a trial tenon: set the fence to cut on
the waste side of the line and make a test cut
11 Turn the piece over left/right and cut the
opposite cheek
12 Cut off the waste by hand and try the tenon for width in the trial mortise. Repeat this experiment,
adjusting the bandsaw fence, until the tenon produced is a nice sliding fit
13 Mark a shoulder line on another piece and
pass it through the bandsaw up to that line
16 Now for the shoulders. If you’re lucky enough
to have a decent mitre fence with your machine,
then of course you can use that
14 Position a stop piece against the end
- note the notch to allow sawdust to clear
17 Mine’s too sloppy a fit in the slot for accuracy,
so I use this MDF triangle against the rip fence
15 Flip the timber left to right and cut the second
cheek. Cut all the tenon cheeks before disturbing
this setting
18 For safety, clamp a short sub-fence onto
the rip fence, stopping just short of the blade
will be in the manual. With all those sorted,
some of the finer points need to be checked.
The blade must be cutting straight and true
- parallel to the fence and perpendicular to the
table. It’s very important that both these settings
are precise or the tenons – and therefore the
whole project – will end up twisted. The easiest
way to test this is to cut some timber.
Set the fence just a few millimetres from
the blade and run a straight piece of timber
through. The cut should be absolutely parallel
to the edge from start to finish – but it’s a pretty
safe bet that it won’t be. However, don’t assume
that it’s the fence that’s to blame.
