I spent a last night putting together my new TS and ran into a snag. I
am having trouble getting the cast extension wing to the left of the
blade to stay completely flat when I tighten the bolts.
The TS top and the wing are flat, checked with a straightedge. I tried
a couple of different techniques including clamping some jointed 6/4
maple underneath the table and wing. They're flat before I start
tigthening those bolts. As soon as I do, the end of the wing rises
slight above the height of the TS top and throws it out of whack.
I read some old posts where someone suggested filing the mating sides
of the wing and top, is that a good solution?
Any help here would be much appreciated.
Shiming may be easier than filing, but check there aren't local high
spots causing it that can easily be taken care of by a file first.
Also, is it possible you're over-tightening and thus distorting it?
Its very possible that I'm over tightening. I usually do handshake
tight on blades and bits, but for this I though I should give it a
little extra squeeze. I'll check the sides to see if there is a burr
or paint build up.
I don't want to shim too quick, since they'd have to be near the top
Get them all "snug tight" and then use a rubber mallet
to persuade the edges together. It is time consuming
but will work with patience.
Using the old "Gorilla Tight" is tough when trying to
get a perfect edge.

From what you describe, I'd say it's likely the best solution. Buy,
beg, steal or borrow an all metal machinist's square and check both the
edge of the saw table and the mating surface of that wing.
Both should be perfectly square and smooth. This is really no different
(except for level of difficulty<g>) than gluing up a table top.
From your description it sounds like you've got more material at the
bottom of the saw table or extension than you do at the top since it
(the wing) rises when you tighten the bolts.
As someone else mentioned it may be just a little ridge along the bottom
of one side or the other or may be something more. Only way to find out
is to make sure with a square. Remove the high spot or, as suggested,
you can shim it. Which is better is going to depend on what you find
when you check for squareness.
How much out of whack is it? Who manufactured the saw and is it new or
just new to you? If you can determine that the problem lies with the
wing, perhaps the manufacturer will send you a replacement provided you
can speak intelligently with them about WHY it's not mating properly.
Good luck and let us know how you make out.
This is a new Delta 36-682xl. When I tighten up the bolts and lay the
straightedge (a true straightedge, although not a Starett), it gets
pretty far off the table. May an 1/8 of an inch, although I didn't
measure the gap. I was thinking about calling Delta to hear what they
would suggest. The manual only offers something along the lines of
"insert the bolts".
That is pretty big.
My guess is that it is either a filable high spot or a warped/bad casting.
If it is the latter, you have to determine if it is the main table or the
wing. That should be a warantee issue. I got a bad CI fence for a Delta CMS
once. They sent me a new part pretty much no questions asked.
I suspect delta will take care of you.
I had a similar problem with a cast iron wing on my CS, if I understand your
situation correctly. It was due to poor machining of the wing's mating edge
resulting in that surface being curved inward (or concave if you prefer).
When the bolts were tightened the force sort of racked the top surface
causing it to distort from flat. My solution was to spend $35.00 at a
machine shop to mill the edge flat along its length and square to the top.
The table top mating edge could also be the culprit, of course. New saw,
Best of luck.
I think you may be right. I called Delta and they told me I should try
to start the wing a little below the table top before tightening the
bolts, so that when I do tighten it, it gets pulled into the same
plane. Unfortunatelty, I think they misunderstood me, its the outside
edge of the wing that is lifting.
They seemed very helpful, let's see what happens when we get to round 2
