I am thinking about building a mitre sled for my table saw. I would
like to build something that aligns itself to do a 90 degree cut
automatically. Not having done this before and not wanting to do a
trial and error approach I was trying to work out a way that was self
aligning. I was wondering if people would like to comment on
What I was thinking of using as the reference point for the cut was the
angle between the front edge of the tablesaw top and the mitre slot.
That is 90 degrees on my unisaw to within the measurement tolerance of
my not very expensive square.
I was thinking using MDO plywood for the sled and either more plywood
or hardwood for the front fence.
The idea is that I start off with straight edge on the plywood and make
a dado about 0.5" from the lower edge of the fence. I then put the
runners in the mitre slots and align the face of the fence with the
front of the saw. This gives me a face that should be exactly 90degrees
to the mitre slots. Finally I cut off the surplus fence.
I am trying to work out if this would save time or end up with a fence
that is slightly out because of something I have overlooked and
impossible to adjust.
What do people think?
