  • Delta Blade Lock Won't Stay Locked

    Hi everyone,

    I am new to scrolling and have a Delta 350. I bought the saw brand new almost 4 years ago but life hasn't allowed me to use it until now. I set up my saw and start seeing what it will do. The first couple of times I changed blades, the quick release blade locks stayed locked. Now, all of a sudden, they won't. Can anyone help me please?


    I removed your picture you will need to re-size it and then follow my instructions below.

    I think you need to re-size your picture....

    Just a tip...

          If it is anything like my Q3 and other Delta quick change blade holders, there is a small U-shaped spring which holds the two halves of the blade holder together when you close the lever. If it is missing, it just won't stay closed. Been there, done that.

            George is correct but also you might have to adjust the tension knob that tightens the clamp.

              It appears that from the picture that you might have to back off the knob on the right just a tiny bit until the left lever locks into position. I had this problem before and found this to help me.

                Kenn, I have a Delta with the quick change blade holders and had a similar problem. There was a small piece of a broken blade in it which wouldn't allow the blade to lock. I took the blasted thing apart to see what was going on. There are two springs in that thing: One is the U-shaped spring and another is a very, very, very tiny compression spring. Of course that's the one I lost. I had to get a replacement. So be careful if you take it apart.

                  Thanks everyone for all of the input. I seem to be experiencing everyone's previous issues all in one.

                  I had tinkered with the tension thinking maybe it was too loose or too tight. Then I started taking the clamps apart to see if something was jammed up and whoops, lost one of those springs. I got another spring from the hardware store, put it all back together but still no luck.

                  I'm thinking I may need to order 2 whole new clamp setups. Looks like I'll spend Thanksgiving eating more turkey and watching more football.

                  Thanks again for the help. At least I know I was looking at the problem the right way.

                    Good luck Keen, I have one of those locks on my Delta too. That is the reason I use my Hegner a lot. And I have changed the clamps 4 times..

                      Hi Kenn -no problem at all with my QuickLock clamps - I have the model 2 version on my saw. Assuming you have all the parts in place it does take a bit of trial and error to initially get them to work right but usually adjusting the knurled semi circular tightening nut correctly solves the problem. Screw it too far in and you can't close the clamps without a heck of a lot of pressure and risk breaking the levers, ease it back too far and the clamp won't grip the blade. Also check that the clamping surfaces have no oil on them - A light pass over with a fine size wet and dry paper with help. Don't forget that if you change blade sizes you will probably need to adjust that nut again.

                        Jim - Thanks for the info. I'll see if that makes a difference.

                          A couple of months ago I ordered the Large Pegas Scroll Saw Table for my EX21 from Denny which I received about a week later. I installed it immediately and made a few test cuts. Since then I have been busy with several Urban renewal projects around house as well putting the yard to bed for the winter....

                          Back in the late 90's I bought a Incra 2000 Miter gauge. Incredibly precise. The problem was that it only adjusted in one direction, It rarely gets used. It locks in to half degrees. More recently I bought a Kreg fence which has a pin that precisely locates the frequently used angles.
