I'm betting that the table isn't square to the blade. My Cabinet Makers Table Saw does the same thing - the top plate (the big heavy cast iron plate that weighs about 50 pounds) sits on top of the sheet metal box that houses the motor and motor lift. This cast iron plate is held onto the sheet metal box by 3 screws (usually).

Loosen the 3 screws and the cast iron plate can move around on top of the sheet metal box (the holes for the screws are large enough to allow 1/8 inch movement). Looking down from the top, you can rotate the cast iron plate clockwise and it will move the front of the blade closer to the fence and the back of the blade away from the fence. Counter-clockwise does the opposite.

For the best adjustment, use a dial indicator mounted to something that slides in the track of the table top. Position the dial indicator agains the blade and slide it back and forth in the track of the table top. This will accurately set the table top to the blad (so they are parallel within 0.0005 inches).

Then check the accuracy of your fence (sounds like this is good). Don't forget to check the alignment of your riving knife/guard & splitter to the blade (if it's off you can't feed wood because it will hit the splitter).

On my Dewalt table saw when I lock the rack and pinion part its fine on the front of the saw but its way out of square on the other side. But the fence is fine is there an adjustment so it stays square?


If I read this right the fence is not square with the blade and if so on the backside of the tool you will find 2 hex head bolts that need loosened and the fence run up against the blade, push/pull fence until it is square front to back and snug up the bolts, run the fence away and try again. I always check a couple times, when sure it is square tighten bolts and this should take care of your problem. Let me know if you need more assistance and if I have helped you would you please vote accordingly. Thank you

The blade is not sqare to the front of the table, with the fence next to the blade there is a 1/8 inch differance. how do i adjust the blade or the motor/shaft


you don't adjust anything but the fence if I understand the question correctly. You are using the fence for a straight cut and there is a gap, if so on the back of the saw UNPLUG SAW FIRST you will find a schematic about hhow to adjust the fence but all you have to do is loosen the 2 bolts where the arrows are I believe they are 10MM and lift the guard out of the way then gently run the fence next to the blade and "push" the fence square to the blade and tighten the bolts, usually it takes a couple times (I always recheck it). Now if the blade set at 0 degrees is not square you reset the angle from the front. Let me know if you need more help

Rip fence is out of alignment..what do I need to do?


This is the fundamental problem with rip fences on table saws. I don't know what kind of rip fence you have, but most rip fences are adjustable for squareness. However, unless you have a very nice (and expensive) rip fence, they often don't self-align when you move them anyway. If you have the type that clamps at the front and the back of the table, the problem can be overcome by making sure the rip fence is straight before you clamp it in place. The easiest way I have found to do that is to use an adjustable square. Put the front of the rip fence where you want it, then set the adjustable square so that it matches the distance from the miter slot in the table to the fence. Then move the square to the back of the table and move the back of the fence to meet the end of the square. Now clamp it in place and check the front and the back one more time. It's tedious to do this every time you adjust the fence, but you can get a perfectly aligned fence this way. This method assumes that your blade is parallel to your miter slots, which is adjustable too, but you have to get underneath the saw to do that. good luck, Al K

Adjust angle of band saw blade to align with fence


Typically the fence is attached to the table and the table can be angled to create a bevel.

Using a square, align the table so it's square to the blade. Assuming your fence is square to the table vertically, you're good.

With most bandsaws I have worked with, there is a positive stop (typically just a bolt - the head acts as the stop) underneath the table so when you tilt the table, you can return it to flat without having to re-square everything up every time. Once you've got things square, make sure to adjust the positive stop too.

Be aware you may still have to compensate for drift with your fence, though.

When I try to cut a 45 it seems to be cutting a little more than a 45. how do I adjust it?


Make sure the blade is 90 deg vertical to the saw table. Make sure the indicator is set approprately. Raise the blade just enough to clear the table/base. Place a swanson speed square against the fence and blade. Make sure the indicator is at 90 degrees. Here you might want to tilt the square and check that the complete blade is flush against the sqaure as high up as possible. Lay the square back flat on the table and pull the blade toward you as much as possible. The teeth on the blade should ride against the square extented completely out.

Now set the square against the fence with the 45 degree angle coming away from the table and set the blade on the 45 deg mark on the insicator scale.
The blade should touch the square all the way out fully extented.

Or just experiment with some scrap and check

Blade isn't cutting well. It smokes and the wood rides up as it is cutting. The saw is 14 yrs old but blade has only been used a few times. I think it needs alignment. Can I do that myself?


You should be able to adjust the fence but every model is different so I probably cannot tell you exactly how. My Biesemeyer fence has 2 set screws on front guide of the fence for parallel adjustment to the blade (this fence is a single piece fence). I had a Sears contractor saw that had 2 bolts on the top of the fence that needed to be loosened, the fence moved parallel, and the bolts tightened again (the Sears fence was a bolt together fence). Whatever fence you have I would think the adjustment would be on the front part of the fence. I would remove the fence (the fence only, not the guides) from your table saw and take a close look at it for any adjustment screws (the Biesemeyer set screws are somewhat hidden) . If the fence bolts together you will probably need to loosen the bolts to do the alignment. There is a quick check you can make to verify the problem is the fence not being parallel to the blade because your problem could also be caused by a bent saw blade arbor (the saw blade would wobble as it turns)

ø Lock your fence down and measure from the front of the blade to the fence and from the back of the blade to the fence. These measurements should be within 1/32” (ideally is should be zero).
ø If the fence passes the test above, you can see if your saw blade shaft is bent by sliding the fence very near the blade, locking the fence down, and rotation the blade by hand (unplug the saw first). If the blade rubs on the fence as it rotates then you could have a bent arbor, a bad arbor bearing, or a bent blade.

User manual for adjusting your saw here.
When you set it up, make sure you check for square to the table, square to the fence, and check square for toe-in or at a 45 deg. angle across the blade from the corner where fence meets table, like you would check a radial arm saw. (hold a framing square with one leg against line of fence/table and other leg against blade and inclined 45 to both table and fence. Make sure all three are dead square.
I never found any way to compensate for the play in the blade itself. It seems like the manufacturing tolerances are a little too loose.

You may need a heavier plated blade. You may simply need a different saw. Those Dewalts are great workhorses, and I love the design, but it's my experience that when you're trying to miter hardwoods of any substantial size there's a little bit of drift in the cut as the blade comes through the wood.
You can try cutting at a slower rate.
I've found that makitas are a little more solid through the cut, though I don't like the general ergonomics as much...
Kind of a pain, isn't it?
Well, good luck.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

How to set fence square to blade.dw705


First if you need an owners manual go to Dewaltservicenet.com and in the middle of the page at the bottom type in your model number and get a copy. OK for setting the fence square, first unplug the tool and make sure that the blade isi good. Get an accurate square. Set the table at 0 or 90 degree for a straight cut depending on your scale. Make sure the blade is straight up and down on the bevel before starting. What you want to do is loosen up the 4 bolts on the back side of the fence enough so you can move the fence with some resistance. Set your square on the left side of the blade and pull or push the fence till it is square with the blade, snug up one of the bolts and then put the square on the right side and check for square, you might have to move it some if square snug up one bolt and recheck the left side again, if ok tighten both bolts and recheck the right side and repeat if OK. I sometimes recheck 3 or 4 times just to make sure. Also I should have mentioned about putting a straight edge across the length of the fence to make sure that it is not bent in some way thereby not allowing you to square the blade. Let me know if you need any more help
