Title: Blade Question
Post by: Lakelad on December 01, 2010, 05:18:45 pm
I am cutting out some of the 3D Christmas ornaments and the top portion of my blade is getting to the end of the cut before the bottom part of the cut. In other words if I stop the cut when the top part of the blade has finished I still have a distance to go on the bottom. I have never experienced this problem before, anyone have any thoughts. I am pushing the blade to the back of the blade holder, both top and bottom. I am using a DeWalt 788. is there a blade clamp adjustment maybe?

Sounds like either you are forcing your work, or the blade is not square to the table to start?  Have you checked the blade for square to the table?  Perhaps go up one blade size and slow down your feed rate a bit.  The blade for sure is flexing for some reason.

Check the blade is vertical fore and aft in it's clamps. But it is common to push too hard forcing the blade out of alignment, also check the blade tension may be too loose.

Have you checked the blade alignment, font to back and side to side?   8)

Thanks to all for the advice. I had checked alignment so knew that wasn't my problem. I believe forcing the cut was a major part of the problem. I have done very little cutting in thicker hard woods. In addition I needed to increase speed and also change blades more frequently. Again thanks for all the suggestions, they were helpful.

I had the same problem cutting 3D ornaments, using the same saw.  The diagnosis was the same too--I was pushing the workpiece too fast and therefore stretching the blade which resulted in the uneven cutting.  Working with 2" walnut, I had to speed up the saw and go a little slower.  The end result was beautiful.  Now those ornaments are in the mail to my scrollsaw ornament exchange recipient.  Happy scrolling and merry Christmas.  Jim

Please don't cut like steve good fast and the dewalt scroll saw at  1,000,000 spm lol..  Just slow down and take your time cutting out the stuff that why you got a scroll saw right...... What is the rush.... If the pice that you are cutting is big just take breaks and do something else. Like playing the wii for 6 hours lol....
