Jet Saw - Delta Tenoning Jig

[Firefly556]

I have a Jet JTAS-10 table saw (left tilt blade). My wife bought me a
Delta Tenoning Jig as a Father's Day gift. Today, I finally got to put it
together and set it up. I think everything is OK, but thought I would ask
the experts.

The Delta saws are right tilt. The guide chanel with the leaset clearance
is to the left of the blade. The Jet, being left tilt has the close
channel on the right side of the blade. When I follow the instructions
everything is fine using the channel to the right. I can make the
adjustments and alignments and have it all set to go.

There are a couple of things that concern me.
1. The handles for the jig are on the "away side".
2. The plum support is also away and therefore in front of the piece you
will be cutting.

Any problems? Has anyone out there used this combination?

If I understand it correctly, it sounds like you're placing the jig on
backwards and into the right hand miter slot. If that's true, I highly
recommend against that. There is no support behind the piece while
cutting. I expect it will fly and it can be dangerous. Do not expect the
clamp to hold the piece tight enough to prevent the blade from throwing
it.

If you can't run the jig in the correct orientation (and thus in the left
hand miter slot), return it and build your own. The jig works fine but
only if you use it in the way it was intended.

I picked up the tenoning jig some time ago now. I ended up re-drilling it
to make it work on my PM66, but I keep it on the left, as do I the miter
gauge.

With the support in front, I'd worry (only a little) about longer pieces
(depends on ceiling clearance) being stable.

But - when you set up your table saw, which slot did you use as a reference
to set the blade (arbor) parallel ? If it was the left, then I'd move the
jig to the left slot. True the right slot should be parallel to the left,
but some of us get really tight, often within .002" or so. On my saw (for a
certain short run that I can measure) I'm better than .002".

No - not to open up the pandora's box on tolerances again, and my own
personal weakness therein, but I know for certain that every ounce gained
during setup pays dividends down the road, I'm not sure about the ROI.

I didn't see the original post so can only figure that someone is having
problems with a Delta T Jig on a Jet Tablesaw. I dont know why this
problem exists. I have a Jet saw and use a Delta Tennon Jig with it
regularly. Its fits perfectly. If the original post reads this article,
Email me and I will discuss.

Ken,

I originally posted this question:

I have a Jet JTAS-10 (left tilt saw). I received a Delta Tenoning Jig
for father's day from my wife. The jig will align ok on the right of
the blade, with the handles and plum support facing away. The slot on
the left of the blade is further away from the blade, and therefore,
can't be used.

I have looked at the jig a little further and realize I can add 3/4" L
support to the jig and have it work ok. I was concerned if I ran it on
the right of the saw blade the jig would create a saftey problem.
