thepopela Posted March 22, 2017 Report Share Posted March 22, 2017 Hi all, Could anyone point me in the right direction? i seem to be braking lots of blades , i tension the blade so it has a "nice tone" (ive watched the videos) but the blades always seem to snap on the bottom 5mm - 10mm of the blade! Can you over tighten these on the blade clamp? i've tried not doing them up as much but they just pull out after a few minutes then? Im using pinless pegas spiral blades btw. Any advice greatly received. Cheers. Quote Link to comment Share on other sites More sharing options...
WayneMahler Posted March 22, 2017 Report Share Posted March 22, 2017 Slow down your feed rate, heat is a major contributing factor in blades breaking. Spirals seem to be more sensitive to this from my experience since they are twisted to get the spiral. I'm sure others will chime in on this also. sweetsaw 1 Quote Link to comment Share on other sites More sharing options...
jerry1939 Posted March 22, 2017 Report Share Posted March 22, 2017 Also check if your left blade holder screw is recessed. If so, when you tighten the blade, the right screw puts a kink in it. amazingkevin 1 Quote Link to comment Share on other sites More sharing options...
ike Posted March 22, 2017 Report Share Posted March 22, 2017 put a new blade in and tighten it put correct tension on it then take it out and If it has a bend in the blade the left set screw is not correct, if it is bent take a ruler put it in the blade clammp tighten it down on the right then on the left that should cure that problem. if it still breaks i dont know.

trackman Posted March 22, 2017 Report Share Posted March 22, 2017 Make sure the left set screw that the blade gets pushed into is out (towards center of clamp)about 1/16". This will keep blades from getting a bend like the blade of a hockey stick and breaking there. I have been scrolling for 7 years and have broken only one blade & it was because of this problem. After you get the set screw were you want it put a drop of BLUE locktight on threads. Will keep from working out. Quote Link to comment Share on other sites More sharing options...
Sparkey Posted March 22, 2017 Report Share Posted March 22, 2017 I stopped using the Pegas spirals because of that. The best spirals I have found are Flying Dutchman. Olson blades are also good. amazingkevin 1 Quote Link to comment Share on other sites More sharing options...

thepopela Posted March 23, 2017 Author Report Share Posted March 23, 2017 OK cheers chaps plenty to think about there, stupid question time though ...when you talk about left and right clamp screws my bottom (and top) clamp only have one screw to tighten, are there suppose to be 2? The top clamp tightens on the right and the bottom clamp tightens from the left. amazingkevin 1 Quote Link to comment Share on other sites More sharing options...

Ok i understand what your saying.Now with out putting a blade in screw the blade holding screw all the way in tight.Where the end of that touches is a set screw which is adjustable too,Usually with an Allen wrench.Top and bottom blade holders both have this adjustments.

The top clamp tightens on the right and the bottom clamp tightens from the left. I think most (or all) brands of saws have blade clamps with a screw on each side. You mentioned that one clamp tightens on the right and the other on the left. IF it's handier for you, the screws can be switched, so that they both tighten on the same side. The reason for a "somewhat permanent" screw on the side that you don't tighten is to align the blade right to left, top to bottom. Hope this helps Friend. thepopela 1 Quote Link to comment Share on other sites More sharing options...
Chiloquinruss Posted March 24, 2017 Report Share Posted March 24, 2017 I looked at your scroll saws manual and its hard to tell from their illustrations but I don't think there are two bottom screws. What I would try just for a test is to try one of your 'pinned' blades because it doesn't use your screws. See if that makes a difference, if it does then you have now narrowed down the problem to the screw holder parts. I would remove the screws and look at the ends of the screws, they may have a burr on one of them causing the blade to be tweaked. Also the manual is very clear setting the tension AFTER the blade is inserted EACH time the blade is inserted. If you are doing a piece with a lot of blade insertions this may also be a cause of the breaking. Hope you get it figured out, scrolling is fun (most of the time)!
