Topic tags/keywords: question scroll saw scrollworking

I just purchased a used DeWalt Scrollsaw 788 Type 1 and every blade I put in the upper clamp does this to them. I have been using two types of blades, Olson and Seyco. Ray at Seyco suggested clamping pressure (amount I tighten the screw) but I have tried less and less. I still get the look of a fish hook on the blade after a few uses. What do I need to do?????

Buy some fish hooks and see if they bend into blades…

I would try tighter, the blade should PING when plucked. Keep tightening untill you get that PING then try running it.

there should be a set screw on the other side of the thumb screw that you use to tighten the blade. adjust the set screw so that it will center the blade in the holder.

I have a DW 788 and it doesn’t do that to my blade – the blades are still straight when they are removed. It looks like whatever mechanical method is being used to hold onto the blade (I haven’t looked at mine closely) is not in alignment on the two sides. It should be pinching closed on the blade evenly on both sides.

Take a close look with a flashlight and see if you can work out a) what is misaligned b) whether you can get it back into alignment. If not, maybe DeWalt customer service can help – I don’t know how helpful they are as a general rule.

I went out and took a picture of the set screw that you ne
ed to adjust. It is some sortvof a hex screw but I didn’t measure it.

I also discovered that I need to really adjust the screw on one of my saws.

YES – I think that Mrs. N hasw answered it. ALSO, I need to start using less torque (tighting the screw) on the blade. On my old saw I had to really clamp down to make it hold.

If you find you are needing to put a lot of torque you can try cleaning off the tips of the thumbscrews and set screws. Sometimes they get oily residue on them. Also over time the screws may get a little rounded on the tip and you may need to sand them flat again. I always clean my blade tips off with paint thinner when I first put them in to remove any oil they may have on them which seems to help quite a bit for me.
