I just bought a new dewalt scroll saw and the blade goes from front to back about .060 you cant see it unless the speed is turned all the way down but i started doing some fret work and couldnt get around the corners without the corner getting all chewed up. It took a little while to find the front to back movement i still dont know why or how to correct it if it is even possible to correct it my older hitichi saw has a longer arm so the radius is way longer and there is no front to back movement and going around corners is much better so i have a new expensive saw but have to use the old one for anything with corners and everything seems to have corners. I took it to the dewalt repair shop and they didnt have a clue as to why it does that or if all dewalt saws do it that is hard to believe seemed like everybody loves there dewalt saws i hope someone on here knows how to fix this problem cause i sure cant use it the way it is. If i put the saw on slow speed and put a block of wood behind the blade and run the saw it will give the wood little knocks so u can see the run out on the blade then I put a indicator on the blade and fun it by hand and then you can read all the movement about sixty thou at least the dewalt repairman just turned it on full speed and said just use it that way but the blade has the same movement ya just cant see it…..but he tried got to give him credit but he had no ideas on how to fix it if they are all like this i need to find another saw dont know what to do with this one tho…..well thanks

If you just bought it locally, you may want to try returning it and see if the replacement is better. The quality control is definitely lacking on these saws. Excessive front-to-back motion is a VERY common issue with new Dewalts and is the biggest reason why we made the switch to a General International Excalibur. The quality of the DW788 has gone down significantly over the years. The older type 1 DW788’s were 13 lbs heavier than the ones you get now! I would think that significant of a change should warrant a new model number but they just chose to cash in on the reputation of the type 1 DW788’s.

Here’s a link to where some people have found a solution that worked for them… (scroll down to the post titled: Front to back blade movement fix; DW 788 blade forward travel)

I would really hate to do this to a brand new saw though because you are going to void your warranty. Like I said you should return it and hope you get lucky or take the plunge on an Excalibur. The problem is quite common and I know some people who have taken the second Dewalt home and returned that one too.

The 16” Excalibur is only slightly more expensive than the Dewalt. If 16” is big enough for what you do than I would seriously encourage you to go that route. The 21” is significantly more expensive but if you need the size and can swing the cost, then do it! The front-to-back motion of the blades can be adjusted on Excaliburs without modifying parts or voiding any warranty. If you are in the US you can get an Excalibur from http:/, they take it out of the box themselves and pre-tune it for minimal front-to-back motion. If you buy it elsewhere just PM me and I will explain how to do it or find the instructions online for you, should you decide to go that route. It’s simple to do and only takes a few minutes.

Our Dewalt was the older type 1 and still had significantly more front-to-back motion than the Excalibur after tuning. I was quite used to it since it was all I had ever used but my scrolling definitely went up a level with the upgrade to the EX.
