I have been using a pair for about 7 years now. I recommend getting one for
both sides of the blade. IIRC there is a break when you buy both sides.
It is a great tool that enables accurate miters, repeated length cuts and
easily cut wide panels.
Keep in mind, that the Dubby sleds are great tools however they are
considerably larger that they typical miter gauge but about the same size as
any other sled.
With that in mind I also ended up buying a precision miter gauge, The Kreg,
a few years after buying the Debbys. I wanted a quick way to make one or
two 90 degree cuts with dead on precision with out having to look at the
markings on the gauge to insure it was set at 90 degrees dead on and with
out having to pull out the sled.
The EB3 is a cool concept but I have not seen one yet that locks up solidly
at "both" 45 degree settings with out having play in that setting. Another
poster recently bought an EB3 and seems to be happy with it. Perhaps after
dropping the EB3 price to about half of what it was a couple of years they
also beefed up the telescoping angle setting bar. Maybe the other owner was
not looking for a the same tolerances that I do. The current Delta badged
version of the EB3 still has the inherent problem that the models a few
years back had.
I heard about the EB3 problems, I still like the idea, but, I do agree about
having a precision Miter Gauge. I have an Incra and it is dead on 90, plus
great stock support even for long pieces. I just hate trying to reconfigure
it for miter cuts and having my Zero Clearance backer board ruined.
Looks like the dubby is the way to go.
There you go. You should be set.
The EB3 is a miter gauge and does not offer the features of a miter sled. I
really don't think you would gain anything by getting the EB3 even if you
got one that worked correctly given the fact that you already own an Incra
Let me throw out a few more observations and points about the Dubby.
These can be plusses of minuses.
1. If you have 2 table saws you should dedicate a Dubby jig to only one as
you trim the Dubby to a particular TS during set up. This creates an edge
that is next to the blade and gives you a reference point to measure from
when using the adjustable stop. This edge also acts as a zero clearance
back up on the bottom of the keeper side of the cut.
2, Like many type sleds the Dubby goes from a 90 degree cut to a 45 degree
cut. A miter gauge that goes from one 45 degree setting past 90 degrees to
the other 45 degree setting affords you the ability to cut asymmetrical
stock much more easily. The problem with being able set the fence to both
45 degree angles on the same side of the blade is that when you have the
fence set such that the end closest to the blade is the leading end, the
exit side of the cut is more prone to tear out. When the end of the fence
closest to the blade is the trailing end of the fence the cut is much less
prone to tear out on the exit side of the cut.
IIRC the Joint Tech miter sled will let you cut both 45's from the same side
of the blade but the draw back is the greater possibility of tear out on
some 45 degree cuts and because the fence swings a full 90 degrees vs. 45 on
the Dubby the sled takes up a lot of table room behind the blade and you are
restricted to narrower stock or panels than what the Dubby will let you cut.
3. Dubby offers a left and right sled so that you can always cut left and
right 45's with the blade end of the fence always trailing the lead end.
The second jig also affords you the opportunity to tilt your blade and not
cut into the sled by using the sled on the opposite side of the blade tilt.
4. You do cut through the fence at the saw line and this tends to erode the
fence as you make angle cuts other than 90 degrees. The good news is that
this portion of the fence is easily replaceable although this has not been
an issue for me and had not increased tear out on the exit side of the cut
with less fence support. Again, because the blade side of the fence is
always even or the trailing end of the fence, tear out is less likely.
I have one. It works very well. But...buying a Dubby is very
analogous to buying a workbench, instead of making one yourself. Its
just a wooden sled and pivoting fence. There are about 10,000
articles and books on making cutoff sleds for the table saw. I built
my workbench many years after acquiring the Dubby.
