Title: Blade Twisting when making turns
Post by: Richard 33 on March 07, 2017, 10:23:18 AM
Hello to all. When I make turns while cutting my blades are twisting causing mistakes and I am also having trouble with it cutting straight. I am using a Dewalt 788 with Olsen blades while cutting 3/4 inch rough cut pine. I have tried every blade I have. OLeson 2/0 through 7 Ultra reverse blades as well as Bosch blades.
I am sure that many newbies have asked this but this is a new problem for since I have not had the issue before. I have been scrolling for almost one year and while that is not a long time and I know that I still have much to learn, I know that something is very wrong. I just hope it is something I am doing or not doing.

thanks for the help
Richard

Well, my first guess would be not enough tension on the blade.  Also, when you do a sharp turn, you need to give the blade a pause to catch up.  Watch the blade when you turn you will see it does not turn a quickly as you make the turn.  Pause a fraction of a second and you will see it the blade "come around" to the new direction, provided the tension is right.  The thicker the wood the longer the pause required. 

I have read posts where the tension mechanism on DeWalts can lose it ability do give adequate tension and I think there is an adjustment that can be make.  Maybe some DeWalt owner on here will speak about that.

I would agree with scrappile but, I would also suggest that when you come to a corner or place to turn, you just stop cutting for a split second, backup just a small fraction and then go back in for the turn. That will give you just a tad more saw kerf for relief for the blade to turn in and not bind.

I would suggest skip tooth blades on material as thick as you are using along with the previous advice.

Thank you all for the advise and tips. I will try them and let yall know if that corrected the issues.

I have noticed that I have had to increasingly  increase the tension adjustment on my saw. I will also see if i can find the adjustment that was mentioned above. Thanks again

Richard, go online to:  http://www.scrollsaws.com/

On the left side of the screen go down the list of items under "Reviews" click on "DeWalt Tune up"

Scroll down about 1/2" page and there is an article on adjusting the tension....   I do not own a DeWalt any more so I don't know if it helps you but worth a read and try.

Thank you for the advise.
Increasing the tension and slowing the speed of the saw along with slowing the turning speed seems to have corrected the issues.  I see it was user error the entire time.
Thanks again
