The recording is a little over a minute long and starts at the lowest speed setting and goes to the highest and then back down again. And I appreciate your thought that I might be hearing a perfectly normal sound and just don't know it. I wish that were the case, but I don't think so. But as my mother used to say: "You are never so right that you can't be wrong". DW788 Sound.mp3 1.78 MB · 10 downloads Definitely doesn't sound right. I think it might be time to go back through it and recheck everything. Something is out of whack for sure. Quote Link to comment Share on other sites More sharing options...
Scrappile Posted January 7, 2021 Report Share Posted January 7, 2021 (edited) I have not followed all of this thread,,, because I no longer own a DeWalt but I will ask/suggest two things... Check youtube if you have not.... That is my first go to repair place.... There are videos on all types of repairs/rebuilds on all types of equipment.... and two, I know there are two, maybe more sites/videos on the DeWalt scroll saw...and I think they are mentioned in this thread.... . If they do not discuss your problem.... have tried to email them and let them listen to your recording.... They may be willing to help.... Having owned a DeWalt scroll saw,,, I know you have a problem.... It does not sound normal,,, at all... but it may and probably is an easy fix...

I think I've found all the videos and reference material that's on the net and am always looking for more. with any luck, this problem will be solved in a few days.

Kevin, Yeah, the bolt on the connecting rod is double nutted so no worries there on my unit. The problem reminds me of trying to find a chirping cricket in the house. It's gotta be in there somewhere! OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...

But miniscule play here and there adds up to big play somewhere. Car axel grease in ALL the bearings cure that going on 5-6 years now of heavy scrolling. It's hard to pull more than 1.5 on the blade tension dial, Usually I'm add 1 OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...

Yeah, roger that on the car axel grease - I got the Valvoline full synthetic and used it for all the bearings/sleeves - except for the connecting rod - which is in the mail coming to me. My son-in-law is a mechanic and has the drift tool Ray used in his video to spread the vertical assembly in order to remove the connecting rod from it, so I am optimistic in being able to make that replacement. Really hoping that will be the source of the knocking. But even if it isn't, it will eliminate that as the cause and help zero in on where the knocking is coming from.

Dick heppnerguy Thanks Dick. I had not seen this one before and I learned something from it. I was under the mistaken impression that it was the tension rod that was striking the cover. I didn't didn't know it was the upper arm. So, with that said, I must take back my previous instruction regarding the rod. This video gave a very good example of how much and where to remove material from the cover. I didn't have to remove that much from mine. Just goes to prove the old saying that you're never too old to learn something. Quote Link to comment Share on other sites More sharing options...

I ran across this post a couple of months ago and found it a lot shorter and more to the point then the others. I tore down a DeWalt scroll saw that I gave to my grandson several years ago and cleaned and greased everything and it ran like new. I did not have to do anything with the upper arm on that machine. I am glad you found it helpful also. Dick heppnerguy OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...

I have 2 of them and one DeWalt. I bought my first Ex from Paul (Scrappile). Then I continued a search to find one more for a backup. They were hard to find, once they stopped producing them. Everyone seemed to be hanging onto what they had. I finally got lucky and found one on Craigslist in Phoenix. It was about three years old and purchased for a grandson to give him something to do when he visited him in the winter. But fortunately for me, the kid only spent a couple of hours on it and never was interested and did not touch it again. So it sat unused from the first hour or so it was used. Finally the grandfather decided it was taking up space in the shop for nothing and posted it. An hour after he made the post I had it in my car and have been using it every since. Oh, by the way, I got it for $200 Dick heppnerguy OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...

kmmcrafts Posted January 12, 2021 Report Share Posted January 12, 2021 A little cumbersome but a C-clamp or a bench vise and some pieces of pipe or sockets can press the bearings too.. I'm sure there are many other useful ways of doing it as well.. OCtoolguy and amazingkevin 2 Quote Link to comment Share on other sites More sharing options...
