Dave Monk Posted February 17, 2016 Report Share Posted February 17, 2016 I have a new Dewalt scroll saw and I am also new to scrolling. I was cutting some 1/2" mahogany today and when I cut a right angle corner it seems like it makes a lot of noise. It is the same type of noise it makes if I don't put tension on the blade. Is this normal? dave Quote Link to comment Share on other sites More sharing options...
NC Scroller Posted February 17, 2016 Report Share Posted February 17, 2016 (edited) While turning did you accidently put a lot of sideward pressure and actually push the blade to touch the side on the insert hole. There is enough flex and play in the blade that it can and will happen if not careful.

Dave Monk Posted February 17, 2016 Author Report Share Posted February 17, 2016 (edited) Scott, I don't think so but I will watch that, dave Edited February 17, 2016 by Dave Monk Quote Link to comment Share on other sites More sharing options...
Fish Posted February 17, 2016 Report Share Posted February 17, 2016 I had that problem, if it's the same thing, I didn't have enough tension in the blade. Quote Link to comment Share on other sites More sharing options...
dgman Posted February 17, 2016 Report Share Posted February 17, 2016 Tension, tension, tension!!! In my opinion, you can never have enough tension! Dave Monk 1 Quote Link to comment Share on other sites More sharing options...
LarryEA Posted February 17, 2016 Report Share Posted February 17, 2016 If the side of the insert hole has blade marks, then the blade did touch, otherwise not the noise maker. How does the saw sound with the blade in and tightened and you are not cutting? Increase the speed, does it sound 'normal'? If not then see if you can isolate the offending noise.

Jim Finn Posted February 17, 2016 Report Share Posted February 17, 2016 I suggest you find out what is doing this. My DeWalt was making that kind of noise just before it literaly fell apart in 2008. It was 20 months old, out of warranty so I bought a Hegner and never looked back. Quote Link to comment Share on other sites More sharing options...
Dave Monk Posted February 17, 2016 Author Report Share Posted February 17, 2016 Thank you for all the comments. I used it today and used the max tension that the saw has. Seemed to work better. I was surprised that a #1 blade did not break on max. dave Quote Link to comment Share on other sites More sharing options...

By the way... blades do stretch, (yea I know... not much) and there is slippage and you may need to tighten while you cut.

CharleyL Posted February 18, 2016 Report Share Posted February 18, 2016 Dave, When putting a new blade in my Dewalt 788 I have developed the habit of installing the bottom end of the blade first. Then I apply several pounds of downward pressure with my fingers on the upper blade clamp to remove any play in the upper blade mechanism, and then tighten the upper blade clamp to the blade. I then pull the tension adjust handle, usually to 3 1/2 or 4, and I'm ready to begin cutting. By applying the downward pressure to the upper blade clamp before tightening the blade clamp I've found that the blade tension setting becomes very repeatable. This is just free a suggestion and you may have already learned it, but it took me a while of using my 788 before I learned to do it.

jerry1939 Posted February 19, 2016 Report Share Posted February 19, 2016 Charley, I've been a back words sort of guy all my life. I'm a Delta top feeder and I put upward pressure when tightening the bottom clamp. When tensioning the blade in a tiny hole, sometimes it pulls the wood into alignment with the blade. If so, I remove tension and re-clamp. Works well for me. jerry Quote Link to comment Share on other sites More sharing options...

ike Posted February 19, 2016 Report Share Posted February 19, 2016 I tighten the blade at about 3/4 maximum on my DW 788 and I have my tension adjusted to where full pressure is hard to get. It all in The inter adjustment of the machine. find out where the blade pings at a high pitch by using your fingernail . and as Kevin ask what speed are you running, I very seldom run it above 5. and a blade usually last me 1-2 hours, i CAN TELL BY THE WAY IT CUTS AS WHEN TO CHANGE THE BLADE THIS COMES WITH EXPERIENCE. Today I changed the blade after about 1 1/2 and I was cutting 3/4 popular..It just didn't seel right to me. Quote Link to comment Share on other sites More sharing options...
heppnerguy Posted February 20, 2016 Report Share Posted February 20, 2016 sometimes my saw gets really loud with a combination of some woods and some blades. changing to a different blade will make all the difference in the world. I really do not understand the whys of it but it is what it is Dick heppnerguy Quote Link to comment Share on other sites More sharing options...
