I recently purchased a timberwolf 3/8 4 t.p.i blade for my 14 inch bandsaw (from Amazon). It is making a clicking sound and the cuts are VERY rough. It also sort of looks like it has a wobble when it is running. I have heard that you can grind the weld to make it run smoother. Is it worth it? or should I send it back to Amazon and get a replacement?
