DW788 table out of square. Can you check yours?

[harrisg]

As mentioned on a previous post about my new DW788, I could square my blade on the right side of the table but not on left. I put a straight edge from right to left on the table and it was NOT flat. As you probably know, these tables are cast and then machined flat.

I went to exchange my table at Western Tool, the place I bought the saw from. However, the table they wanted to exchange had the same problem. It also was not flat. Fortunately, the Dewalt repair station was a short way down the road and when the tech checked the table with his straight edge, he saw that it had a crown of about 1/8". Thank goodness he agreed with me because I thought mabybe I was being too pickey. I had to leave the table there and of course their sending me a new one.

I have only been scrolling a short time and am already feeling withdrawals. What the heck, it'll give me some time to fix up a dust collector on my radial arm saw.

Now for the question. For those of you with a DW788, if you have the time would you please put a straight edge across your table, just in front of the blade opening and tell me what you find?

I found that if I put a straight edge across my table that it touches one side, the center, and that there is a 1/16" gap between the opposite table edge and the straight edge.

So I checked my well used/thoroughly thrashed Delta 350 and found the table perfectly flat.

I then checked my table saw table - flat, drill press table - flat, and truck tires - inflated..........

I'll be curious to hear what others find. Please keep us posted on any news from Dewalt.

I haven't noticed any problems with cutting detailed fretwork. Just finished cutting some small flowers last night and the edges don't appear angled or skewed.......

I also noticed that I'm no longer a "Junior" member.......

Mine is dead on flat. I will give you another detail to check if anyone is interested. It came up on another forum and I have a email into Dewalt but have not gotten any answer yet. Harris, when you go back to the place where you bought the saw ask the guy to check the relationship of the blade to the table front to back. In other words take a small square and place it on the back side of the blade. Make sure the blade is in the holders correctly. If they do not have a short square you can take the blade out and turn it around and check from the front with a larger square. But after the blade is in place and you have the square just touching the blade push the blade by hand through it's motion and observe the relationship of the blade to the square. It has been found that the blade is always leaning forward and the back of the table needs to be lifted. Now this does not come into play much with pieces up to 3/4" but when stack cutting and doing 3D work it just may because the bottom is overcutting more than the top.

If you have a Dewalt and would like to check that out and let us know it would be fine. Also if you do do it can you tell us where your saw was made if it is an older one it was made in Canada and the others are now made I think in Taiwain or somewhere. I have never seen this brought up before until recently.

I just checked a brand new 788. The table is significantly dished, easily 1/16" or more, front to back and same side to side. I guess I will be making some telephone calls. Didn't bother to check the tires on the truck. Seems like a saw that sells for the mid-$400s should have a flat table?

[harrisg]

I received a new replacement table in about a week and it's dead on flat. I agree with the last poster. For $400 plus, there should be better QC on the tables. Also, how much could it cost them to add something to hold the arm up when inserting the blade on inside cuts?

On the other side, I LOVE MY DEWALT.....

This is what you get when these big companies try to save money and ship the work overseas. I agree the QC should be better and that is the case with anything. Just kep the production line moving we will fix it later is their motto. As far as the arm lift the reason it does not is that saw is designed to be a top feeding saw. That means you need to have the arm stay down while you insert the bottom part of the blade into the holder. People over the years have gotten creative to adapt it to a bottom feeding saw. In this case you want the arm to stay up and out of the way. Some people use a chunk of wood under it, some use a bungie cord and some use the device made for this purpose a "Jim Dandy" easy lift system which is easy to install.

One other thing that so far no one has bothered to check on their Dewalts is front to back blade travel. Does the blade travel at a 90 degrees up and down within specs. I along with many others have found that the older saws had the table tilted too high in the front and this would show up if stack cutting over 3/4" or doing 3D work. Just thought some would like to check their saws. Being you taking the time to look for flat table tops.

Actually them now being made overseas has nothing to do with the bad tables on those saws. Before I upgraded from a DeWalt saw, mine had a severe dip from the center hole to the front but I didn't check it until after it was out of warranty so they wouldn't replace it.
It was a common problem with those saws from day one even when they were made in Canada. It is just a lack of quality control.
I have heard that some people took their table to a machine shop where they plane cylinder heads for cars and get them planed dead flat.
Hope this tip helps some DeWalt owners because I have never seen it mentioned on any of the sites before.

It's the yellow box that looks like a thought balloon used in cartoons.

Well woodbutcher, you learn something new every day. I didnt see that one
I usually just click on the quote down below. Someday I will look at all the features this board has to offer.

Well, salt me down and call me peanuts. That was toooo easy and I feel embarrased now about asking about it.
Thanks for the help.

OK woodbutcher, I'm going to ask you a dumb question. Where is the yellow box? Go easy on me because I'm from Indiana.

Come on Bob! The Canadians found it, eh?

I finally remembered to check my saw tables last night. On the older dewalt (by older,its a 8 month diffrence in when I acquired the saw,not actual manufacture date)on the older one, the table is dead on flat across the table, and it is about 1/32 inch lower at the very back corner. Im guessing on 1/32,but 4 pieces of paper can slide under the straightedge at the back.On the newer dewalt the table does appear to be just a touch higher at the blade hole. Not quite 1/32 of an inch higher going across the table,but slightly more then 1/32 going to the very back of the table. On both of my yella saws, from the front edge to the blade hole its perfectly flat. Ive never even thought to check it for flatness before,and now that I know its not perfectly flat, I plan to just keep using them as I always have,because if I havent noticed any trouble because of it by now, chances are,I never will.

I checked mine today and found it to be off, but no more than about 1/32 and that's at the outside edges.
I can live with that, I'm not making parts for NASA!
