I watched the video Steve posted a couple of days ago about the Dewalt 788. In the video Bob said the blade clamp should move. I have attached a video of my upper and lower clamps. Is this wear & tear, would just replacing the clamps fix the issue. I am hoping to get the Pegas clamps for Christmas! These are the links to the videos as I couldn't figure out how to upload them here. Let me know if you can't see them and possibly how to show them (not very tech savy). https://imgur.com/a/pmnzTRi

Hi Barb,
First let me preface this by saying I'm new to scrolling and the DeWalt. However, I'm not new to mechanics. These bearing are loose. I don't think replacing the holders alone will have much effect
I just compared your video to my new DW788. I'd estimate that yours have 20 to 30 times more slop than mine have.
First make sure the blade holder bolts are tight. The bushing should be clamped tightly between the sides of the holder block. Next I would disassemble and inspect the needle bearings and inner sleeve for wear.
I took a short video of mine but the file size is 20.3 MB. I could email to you if you like.

I'm not familiar with your saw and certainly not very 'mechanical' but, I'd sure try removing the bolts and putting thin washers between the clamp and the holder to see it that would tighten it up.

That would be interesting to see, you could email it to puzzledplus1@gmail.com.
Thanks

Barb: Video and additional info emailed to you.

Barb, if you want to open up the saw and to replace some parts, I put a couple of links in a recent post that will help you with the process.
https://www.youtube.com/watch?v=bNt2Y0ajDwk (https://www.youtube.com/watch?v=bNt2Y0ajDwk) and https://www.youtube.com/watch?v=3P4E1At82lc&feature=youtu.be (https://www.youtube.com/watch?v=3P4E1At82lc&feature=youtu.be)
They are long, but sure helped me getting into and lubing my saw.
Good luck,
Jim

I would like to thank everyone for their help. I went to or called 4 different DeWalt service outlets here. None of them had the "short sleeve" part in stock and it would have to be ordered in. Estimated time anywhere from 5 days to 3 weeks. Each sleeve was aproximately $10. I was looking to replace the 4 on the clamps. Decision time - I was going to put the Pegas clamps on my Christmas wish list. It is not on the list anymore, just ordered them this afternoon. :) Should be here in a week!! Yes the Pegas clamps are twice the price of the sleeves, but I am sure it will be more than worth it. Can't wait!!! Hope Canada Post doesn't actually go on strike!

just fitting new clamps is not going to rectify the bearing problem
here are the sleeves

Thanks Dave, I was under the impression that the new Pegas clamps replaced the whole area. I guess I will wait to see when they arrive later this week.

Barb,
I found this video on installing Pegas clamps on the DW788. Note that the clamps installed are the earlier version before the model for the DW 788 was available. I have not watched all of the video. I believe everything comes with the new clamp heads.

Barb - did they make a difference?
The only silly questions are the ones not asked....

I put a set of the Pegas on my Ex 21 and it made a ton of difference. And, I love the way they apply the tension. I'm going to order the Ex set for my Dewalt because of the tension lever system. I should be able to set the tension on the Dewalt with their rotating lever and then leave it in that position. From that point on, it's just flipping the lever on the Pegas clamps.

Yes they did make a difference. Very quiet, not much vibration. That being said, now I am hearing other noises. Might just have to lube up the other bearings - or get the mechanic son-in-law to do!!!

In another post it looked like the Pegas clamps come with new bushings so you didn't need new ones from DeWalt.
Is that correct?

That is correct. I actually phoned Bearwood to confirm. They in turn phoned Steve Good who confirmed that everything you need comes with the Pegas clamps.
