Ksmith Posted January 28, 2019 Report Share Posted January 28, 2019 Hi i have a small benchtop delta bandsaw, i was cutting out the rough shape for a spoon the other day. Any time i would try to make a curve the blade would twist and stop. These arent sharp curves i wonder is it just a weak saw? Or is it something i am doing wrong. Any videos that may help? I dont really do anything big, not yet anyway so id hate to go out and get a more expensive saw if its just failure on my part Quote Link to comment Share on other sites More sharing options...
I B Posted January 28, 2019 Report Share Posted January 28, 2019 Is there enough tension on the blade and are the blade guides setup correctly? 1 Quote Link to comment Share on other sites More sharing options...
bleedinblue Posted January 28, 2019 Report Share Posted January 28, 2019 Not enough info to diagnose really...but some of my random thoughts are blade tension, feed rate, blade sharpness, and the type of blade (number of teeth and width). 1 Quote Link to comment Share on other sites More sharing options...
drzaius Posted January 28, 2019 Report Share Posted January 28, 2019 Is the drive belt tension right? 1 Quote Link to comment Share on other sites More sharing options...
Gary Beasley Posted January 28, 2019 Report Share Posted January 28, 2019 How wide is the blade? Too wide and the blade binds. Another thing to check is if the tooth set on the blade has been flattened making the kerf too narrow for the blade to make its turn. Next check your guides and make sure they are set correctly for the blade, improperly set roller guides will flatten the blade. Next is the blade still sharp? A dull blade will bind in a curve because its having to work the machine harder. That not everything but should help. 1 Quote Link to comment Share on other sites More sharing options...
RichardA Posted January 28, 2019 Report Share Posted January 28, 2019 There's a video by the Carter company, that gives a detailed explaination of how to set up your bandsaw properly. It applies to any bandsaw. I had a link, but can't find it. Follow the directions completely. There may be some parts that your small bandsaw doesn't have, but paying attention will get you fixed. 1 Quote Link to comment Share on other sites More sharing options...

Byrdie Posted January 28, 2019 Report Share Posted January 28, 2019 A Delta benchtop - is that a 3 wheel saw? I think we might need some more specifics about the saw, or a picture. Tension, blade width, drive belt tension, tightness of turn are all possible factors but if it's a three wheel model there might be some other dynamics involved.

Ksmith Posted January 28, 2019 Author Report Share Posted January 28, 2019 This is the bandsaw i have. I watched the video with alex snodgrass on bandsaw setup and im looking forward to setting up mine based on his recommendations thanks everyone Quote Link to comment Share on other sites More sharing options...
RichardA Posted January 28, 2019 Report Share Posted January 28, 2019 Keep a copy of that video, you'll find you will be going back to it for awhile, until you master the saw. Quote Link to comment Share on other sites More sharing options...
krtwood Posted January 30, 2019 Report Share Posted January 30, 2019 In addition to what others have said, it can also be technique. The blade can only turn when it's cutting. If you try to do what you would do cutting paper with scissors and pivot the scissors to change direction while you aren't cutting the blade will just bend. Particularly where the bowl of the spoon comes back into the handle, that IS a sharp turn. A 1/4" or larger blade won't be able to do that without a relief cut. Also the blades for those small saws are thin and tend to not have much set. I usually used a 1/8" blade unless I was trying to cut straight. What people give for advice is really geared toward larger saws (14" and up). Quote Link to comment Share on other sites More sharing options...
RichardA Posted January 30, 2019 Report Share Posted January 30, 2019 By the way, the answer to the title of this thread is , Yes! But it's solvable. Quote Link to comment Share on other sites More sharing options...
