The Last Moxon Dovetail Vise
Many
of my projects involve bow fronts, which result in compound angle
dovetails ...
I
do enjoy building furniture with dovetailing challenges.
Between
furniture pieces, I find time to build a new tool. This time it is
the Moxon dovetail vise I have been promising myself for a while. My
first and only one was built in early 2011, after Chris Schwarz
helped put it on the map. I immediately modified this design, and
have been making modifications since.
(Link: http://www.inthewoodshop.com/ShopMad...etailVise.html).
This new Moxon incorporates the best ideas.
Ironically,
this design is not geared for compound angles. I decided to heed my
own advice and keep it as simple as possible, and cater for the 90%
of the dovetailing that is likely to be done.
The width of
the vise is narrower than my previous one, but capable of 450mm (17
3/4")between the screws. Most cases I built are between 350 -
450mm deep. My previous Moxon could do 560mm (22") between the
screws. This is unnecessary, and just makes for a very large
fixture.
Where the old Moxon used wooden screws, which I
turned, this uses steel Acme screws and iron wheels ala BenchCrafted
... except that these came via Tom Bussey (thanks Tom), which
amounted to a large savings. The wheels are 5" in diameter on a
3/4" Acme screw.
The front chop is 5 1/2" high,
and the Moxon is built in Jarrah ... what else do you expect! I
went a little OTT in this build, but it was fun, and I admit I did
become a little carried away
Brass
inlay ...
The
chop runs on bronze bushings ...
Lining
the inside of the vise is rubberised cork. This makes a great
non-slip (not my idea - this comes from BenchCrafted, who call it
"crubber". Simply search eBay for "cork
rubber").
This
vise is a good height for sawing ...
There
are a few innovations. The rear of the vise ...
This
is a spacer, and it can be locked into the up position ...
The
spacer has two functions. The first is setting the pin board (10mm)
above the chop to prevent scoring the chop when transferring tails to
pins with a knife (this is more of a danger with through dovetails).
Also, by lifting the work, there will be light behind the pin board,
and this makes it easier to align the edges.
The
crubber makes a great non-slip.
The spacer may be dropped
out of the way, once the height is set ...
The
second use of the spacer is that it has a sliding dovetail at the
top, and this allows for the use of MicroJig clamps. This would be
especially useful for holding wide boards, or tail board which have
developed a slight bow ...
I
have used this on other fixtures, such as a morticing jig.
For
aligning the tail- and pin boards, I prefer a simple wide square I
made from wood ...
The
spacer needs to be dropped out of the way for this ...
Once
transfer is made, reverse the board and saw the pins. This is where
you will recognise that the cove is not simply decoration, but allows
the saw to angle and get closer to the work piece. The lower the work
piece in the vise, the less vibration when sawing ...
And
thats it ... the last moxon dovetail vise ...
