Just want to let everyone know that I found the vibration problem with the Dewalt 788. I looked everywhere on this thing and jiggled and moved linkages to never find any movement that could cause such a noise and vibration. Just as I was about to give up and take it to a service center I found that the M5 screw #27 that connects the connecting rod assembly #82 to the Verticle rocker assembly #8 was just ever so slightly loose. Not enough to cause any freeplay when moving it by hand but enough when the saw is running. I tightened that and good grief it's like a brand new saw. The point being, it was not at all an obvoiious problem so if you have vibration and noise that you can't find a reason for you might try tightening on the aformentioned area. Best to all..roughcut

Thank you Thank you.
I really like my Dewalt 788, but the quality of work was slipppping. I thought I had big problems and I really wanted to finish the project I had started. I opened it (the saw) up and nothing appeared loose but 3 different screws tightended slightly. It is a completely different machine. The quality of the cuts is like a new machine. It is fun to saw again.
Thank you for your help.

Hey roughcut thanks for the info. I've had my DW 788 for about 15 years, just the past week it started vibrating like heck. I cut anywhere from 2 to 6 hours a day, 6 to 7 days a week. I tore it apart yesterday and checked almost everything on it and in it. It's coming apart tomorrow, again. I was sopposed to take it in to the shop.Those guys said they would have it for a couple of weeks. YIKES. I was ready to get me another saw. I have never had any trouble with my saw until last week. Thanks again.

I'm a new member but already glad I joined. My 788 started to vibrate at any speed above mid-range, and it was really bugging me. I haven't opened it up yet to try your fix, but I'm so glad to have a lead to follow! Scrolling with that noise is nerve wracking. Thanks!

I've had to re-tighten that bolt three times. The last time, about two weeks ago, I put some Loc-tite on the threads where the nut goes. I've been trying to do it without taken the rocker arm off, but, if it happens again, I'll have to pull the rocker arm and replace that bolt & nut.
I'm using a used type 1 saw, which, if I read the serial number correctly, was made in 2001. When that bolt is tight it runs smooth as glass.
Now I'm looking at a way to fix the blade travel. I have that infamous 1/16th of an inch between the top of the stroke & the bottom.The good woodworker does not craft the wood for honor. He uses his craft to honor the wood.

Great job in sharing your hints and tips. There are a lot of 788 users on this forum."Still Montana Mike"

Reply to YoraHome Laser w/CNC Engraver/Routerby evilbadgerHere is the thread from when I was building it. I gave up trying to post photos on this forum. After they updated to the new format it no longer automatically resizes photos like it use to, I know I could resize everything on my own but the forum isn't as active as it use to be so why bother.

by markdavdThere are a lot of good points brought up here. Some may be easy to correct, others not so much. As far as Fox Chapel replying to this thread, I am trying to imagine a response that would not have made at least some people upset.
As far as the pattern size in the books, I believe the physical...-

by NC ScrollerI often resize just to fit the size of the wood I have on hand. I agree this is a no win situation because of the various software, hardware differences plus the skill level of us, the end users. Even providing the patterns in a digitized format will no fix this because of the reasons I already mentioned....

by RolfJohn your original post is a valid question. It is a simple thing to put in the original scale assuming that it was on the original drawing. As a minimum the size of the material required can be stated, although that has been a confusion for folks that have built the clock projects. I field a lot of...
