  • bending blades with tensioner

    Hello,
    First off I am very new to the scoll saw and i dont have an owners manuel for the saw I bought because i bought it used it is a delta 16" and it says the model number is 40-560 type 2
    now here is my Question,i put the bottom blade in and then move to the top ,i clamp the top down and the blade looks good but when i throw the tension lever the top of the blade bends backwards and after about 5 minutes it breaks at the bend .
    now im sure i am doing something wrong but i dont know what if anyone can hlp it would be greatly appreciated!!

    Welcome aboard;

    I don't have a Delta so I'm not sure about your specific saw. I have seen blade clamps that bend the blade a little bit when you tighten the screw and then when you apply tension it can break the blade.

    Be sure that the ends of the screws, used to tighten the blade in the clamp, don't have burr's at the ends. If you take the screw out and run it across some 220 or 320 grit sandpaper, you can clean those up.

    Also be sure the screws are centering the blade in the clamp and it is at a 90 degree angle to the table.

    There is a fellow, named Rick Hutchinson who has a lot of scroll saws. I didn't see your Delta saw on his web page, but he may have some info about it. His webpage is: Rick's Scrollsaw.

    Good luck - hope you can get it working and start making sawdust.

        It has the quick clamp on top right? Make sure the top clamp is not binding it should pivot freely front to back.

          You can go to deltamachinery.com then to service and support. Enter your model # 40-560, and you should get a current price and parts price list. To the right should be a couple pdf's in red, a parts list and instruction manual that you can download to help understand the workings of your saw. Most manufacturers offer a service like this for free to help keep people happy with their products.
          Try this shortcut Detail . If it doesn't work then the longhand method should get you there.
          Good Luck, Lou

                    Glad things worked out.

                    I just updated my older PC. The hard drive was 500 gb and eight years old. I cloned it to a one TB SSD (solid state drive). Put the cloned drive in and worked perfectly with all my old programs. The computer is now much faster. The new drive was about $100 and...

                    Once upon a time ( in the 70's) i attempted bow hunting. I believe the bow had a 45 pound draw. I quickly learned that it was not for me. It takes lot of hard work and practice just to be fair at it. Good is a whole different level. I hope you do better than I did.
