Blade "flex" after tensioning

[hippygirl]

I've read that, once tensioned, a blade should not flex side-to-side more than about 1/16"...does the same hold true for front-to-back?

 

Thanks!

Well I have been scrolloing for 10 yrs,and I have never known a blade not to go back a little.There has to be some flex.or it well snap.I have never paid much attention to just how far it goes back but I do know it moves back just a little. Hope this helps

I never paid much attention to it. ???

Blade will flex more side to side because the side of the blade is thinner than front to back.

If side to side is tight then front to back is tight.

I just ping my blades When it sounds right I let it go at that. Don't pay any attention to the movement of the blade.

Front to back with the blade static (not moving) should be very small. With the blade moving the front to back makes the saw more aggressive or less aggressive. True vertical saws (Eclipse) are not as aggressive as a "C" arm saw ( the old Deltas). I don't worry much about front to back as much as side to side.

Most saws use a kiss release stroke ,slight ,slight tip with saw blade in motion ,a slight camming action allows fine teeth to exhaust dust faster to allow faster forward motion of piece ,some highest dollar saws you can adjust that out for straighter tighter turns ,for GP use that slight tip of the blade allows easier handling by saw user ,side tilt only wanted in special cutting effects then back to dead 90 degree side to side on table ,tension is critical to good control .all and all (Jacobs Law)(states if you do not add it , you do not have to remove it ) This goes for Too much Heat , Speed ,F to B pressure & or side to side pressure .( some times a short cut is the longest way to success ,& the shortest to BooBOO's I can hear and feel when tension is not enough ,so can you !

Listen to and feel the slight vibrations of you saw as you do different cuttings of different materials ,when they change look for the reason and cause ! JMHO!

I find that cutting any wood it flexes , some more some less .Just like a guitar string  ,they are very tight but will flex if pushed or pulled .With the blade not tightened properly it will bend more as you cut more from the give and take movement of the blade.Today on my dewalt no matter what i did the blade would come loose right away.I've had dewalts 4 years now maybe more maybe less and have never had this problem. Ends up it's the thumb screw blade tightening screw is bottoming out against the knob i glued on years ago .Once i found out what the problem is i turned in the allen bolt directly across from the thumb screw and the fixed the problem.

With the set screw backing our ,I bet the end of you blade was bent badly ,if you were doing fret work that would have been a major issue  as soon as it moved ! That's one of the main points ,different , uses larger holes , what your using the saw for has a direct bearing on the issues you can have and not be an issue for a long time ,or when you try different delicate ,there is little forgiveness ,for side to side flex on ,or table off slightly ,or a bent end ,everything is the same and totally different at the same time .IT"S USE is relative to the saw's need to be dead on or not !  Spirals come to mind  and #1 and 2's ,jewelers blade ! Very opened uses  From a #9 -#0 ! JMHO!
