Delta Dw788 20" scroll saw

[Melena]

Hello all,
I'm new to Scroll sawer but have been using my saw (Delta DW 788 20") for a few years and have had other S.S's.
My saw is making a chatter when sawing, blade tight, and the tension is set for the type blade I'm using. I am cutting 5/8 pine and while cutting I get a chatter like there are teeth missing on the blade, but it is ok.
Any suggestions would be greatly appreciated.
Thanks, Melena

You are certain the blade is in the right way? Not upside down? Some blades with a skip tooth or skip reverse set can do that, especially in pine.

Melena, welcome & sounds like you might have more than one thing that could cause the chatter. One- The wood piece being cut could be jumping. 2 - the blade may be dull causing it to do that. 3. - Loose bolts or screws inside or around the blade clamps. I have had a clatter sound, even when I hold the work piece down tight. That's due to the kind of wood (hardwood) & sometimes a dull blade. It's hard to know unless we can here it for ourselves. Hope it isn't anything to worry about. Good Luck
