Dewalt trunion bolt

[Plaquerd]

I haven't been on the forum for a while. So I thought I would pass on a "tip" I used to eliminate the table "wobble" on the Dewalt 788. If you own a 788 you know that the trunnion is not the best design and it allows the table to move. I had some problems with fitting some of the pieces into an inlay project I was making and thought this might be the problem.
After doing this procedure I had no more problems with fitting.

I removed the foam pad on the base behind the trunnion a while ago because it just bunched up and made it hard to adjust the bevel.

Trace the inside of the trunnion slot onto the base, remove the table, drill a 17/64" hole in the base of the saw as far to the left or right as possible of the original bolt on center between the traced lines.

Note: Leave room for the head of the bolt in the back of the base, if you drill the hole just right the shoulder of the base will keep the bolt from turning while tightening the nut

Then place a 1/4" bolt through the hole, replace the table, replace the factory knob and set the bevel you want, place a washer and nut on the new bolt, tighten it down, and no more table movement.

Note:This will limit the amount of bevel you can achieve with the saw. But if you need more than 35 degrees just remove the bolt.
Here are two pictures of the finished procedure.

Dave I'm glad that you posted this problem , and solution . I've never had any problems with my 788 yet ,but now I've not done a lot of angle cuts on this saw yet . I use to make a lot a baskets on my old Craftsman and as I recall that it had the same problem also , I wonder if this may be a weak area for scrollsaws in general . O well glad you let us know about this , thanks.......Marshall
