1
⁄32" x
3
⁄32"[0,8 x 2,4mm] mortises and tenons on this
“match frame” were formed (with machine tool bits) on a
1
⁄4"x
5
⁄16"
guide. The
15
⁄32" tenon bit is
7
⁄32" larger than
1
⁄4". The
1
⁄32" bit is
7
⁄32"
smaller than
1
⁄4". A similar metric set: 6mm guide; 1mm mortise bit,
and 11mm tenon bit to produce 1mm joints. Machine tool bits as
small as 0.010" with
1
⁄4" shanks and similar metric are available from
machine tool suppliers.
4-39 For very small joints we recommend attaching a rigid piece
of ply or MDF minimum
3
⁄4"[20mm] to the clamp plate, using
the through screw holes in the plate. This should have its own
mini side stop fence attached for tenons
