If your table isn't flat then you can use the sub base jig to set the blade at 90. If you make this jig make it wider than your blade can cut and don't cut through the back of the MDF fully as doing so will compromise the rigidity of the jig.įinally, I believe the saw head is adjustable for squareness to the table. As is suggested above I often use an MDF sub base and fence assembly for zero clearance cuts. If not under warranty you could try the MDF sacrificial under your work piece.

If the table is in fact not flat and/or the miter carriage is not in alignment with the table wings and your saw is still under warranty I would contact Dewalt. This gap should not be tapered, but even if it is, in and of itself is not an indication of table flatness. The fence is supposed to have a gap under it where it cantilevers over the miter carriage. If you still find that the table is not flat, then you'd have to look at other options from there depending on what is out of alignment.

To be safe you can recess the insert then raise it to meet your straight edge. If the insert is proud of the miter carriage measuring from this point may give you a false reading.

Since the insert is adjustable in the vertical plane having your straight edge end at this adjustable point is not a true indication of flatness across the table. Try putting a longer straight edge across the entire length of the table. In the other, you can kinda/sorta see the light coming underneath the right side fence, showing the widening gap.Īm I crazy? These should all be on the same plane, right? (I am new to miter saws.)Īnd more importantly, is any of this stuff adjustable? It doesn't look to me like it is, but maybe I am missing something. In the one the combination square is resting on the miter table, and you can see the large gap beneath it to the surface of the left table. I tried to take some photos to show the problem. Assuming the bottom of the right side fence is square, you can see a widening gap from the centerline of the miter table going away from the blade. And the miter table itself seems to be at slight angle to horizontal. The left side seems to be about a full 1/8' below the plane of the miter table. The three sections (the miter table and the left and right wings that the fences attach to) are not in the same plane at all. After struggling a bit, I realized the table alignment is completely out of whack. But today I wanted to do so some finer work and had a devil of a time getting square cuts. I made some rough cuts with it in the intervening months and thought it was fine. I have a Dewalt DW715 that I picked up on sale late last year.
