Sliding Doweling Jig
Dowels can be
a great (albeit somewhat slow) way to join wood. Alignment can
be a problem, which requires a jig to accurately place holes. I
have several jigs, but finally decided to build one of my own.
The design is based on an article I saw in Fine Woodworking
Magazine. The two pics that got my creative juices flowing are
to the right.
jig is simply a block of maple scrap with steel bushings super-glued
and pressed into it. I took a great deal of care in aligning the
holes with a fence and stop blocks with my drill press so everything
was as precise as possible.
It is used
with auxiliary fences that I make with any piece of wood. All that is
necessary is routing a t-slot into the fence [I use the Rockler
t-bolts and the bit they sell for routing slots into wood (I use this
for lots of different projects and can't recommend them highly enough)].
[I know I've
said it before but I'm gonna say it again: I will try to update
this page with some additional pics and information since making my
first doweling jig. I've made more, using various methods.
They work incredibly well and in head to head testing with very,
very expensive doweling jigs, my design works better.]
(1) Place two
registration marks on the bottom piece where you want the inside of
the side piece.
(2) Clamp the
fence to the bottom piece, aligning it to the registration marks.
(2b) This is a
profile shot of the fence, showing the t-slot.
(3a) This is
the block with steel inserts, front view.
(3b) This is
the rear view of the block.
attach the block to the fence, align it to the end of the workpiece,
tighten the knobs and drill (I did two of the five holes). Then I
loosen the knobs, align the block to the other side of the workpiece,
and drill two more holes.
(4a) I remove
that fence and guide block and attach the guide block to another
fence that I can use for drilling the side.
(4b) I clamp
the assembly to the side and drill two holes, move the assembly to
the other side and drill the last two holes
the two pieces fit together perfect, the edges are perfectly aligned.
the workpieces over, I check the registration marks and find that the
side meets the bottom exactly where I marked.
