choppy cuts, band saw5/20
Turner mill was at 100% cutting great , had 2 blades sharpened and now my cuts look like a dull chain saw cut them . Have I over tensioned it? Is the blade sharpened wrong , do I adjust guide arms ? . I put an old blade in after trying 2 that were just sharpened . Old blade id better but still some what choppy . Mill has a vibration to it now also . The t handle that controls.the.tracking was striped so I replaced it but how did it strip looks like a lot of vibration hit it ? I was thinking that the.hippy wood was related to the tracking or tension . Hate to think my sharpener guy is that bad . Please any.advice will help .
The set is causing that.
So too much set ? Sharpener guy did a bad job? The blade looks like it has alot more set than other blade does . Or is my guide arm messing up the set ?
Could be the guides but I don't think so causing the choppy cuts. And you might be over tensioning the blade which caused the t hanfle to strip out. The vibration may be coming from the tires out of balance.
Ty, its the first time I've used this guy to sharpen , actually first time I've had sharpened blades for a band saw.I did use a chaimsawmil for a year , band saw smokes the chainsaw by far but already I could sharpen the milling chains myself .
If the problem is the blade, we would expect to see a repeating pattern. For example, if one tooth is set too much, every time it cuts, it will leave a telltale groove.
If the problem is with the tension, then it would be more erratic.
In studying the pictures, I think I see both.
What do you see?
Did your new sharpener ask you for the rpm of your mill? Did he side dress the blade?
I put a new blade on today, perfect cuts again . I have already found a new place to sharpen my blades . The new salesmen said my Lennox blades were a softer metal and he suspects the guy who sharpened it put to much set . I done know , glad the mill is good maybe I can get some sleep now . I also had the tires that run the blade balanced that took out the vibration . I also concluded I had way to much tension, I marked where the.tension bolt was at a good tension so next.blade change I hope to set it at the same Mark . Defiantly need a tension gauge and more experience. Any advice on how to get the wife to let me spend more money this week . Ty.for all the advice , glad to have this.resource to learn.
99.99999% of cutting problems are the blade,,,,,, get a new person to sharpen them... Woodmizer can do most blades if you send them at least 10 I believe
Just got back a box of blades from Woodmizer resharp program in NY.First two blades just fine,last six the tooth set is way off and my boards look like ass. I pride myself on the quality of finish my mill produces,and was very po'd. Boards for the custom order were 18 inches wide and 12 ft long.Cannot plane as customer wanted rough finish.Was smart enough to verify change in finish w/customer before to many were sawn,but had to eat the loss and fill order from my own supply. Not one to badmouth but this will be my third problem with them in years time. Rust out of the box,duration of use and now the Cortland resharp issue. Not a huge customer, but a respected one. Beginning to chafe the underside.
The fellow who sharpened my blades recently sold his shop, so I bought a sharpening system & setter (Norwood). Great move, wish I'd done it years ago. Now I don't wait so long to change blades and get better cuts. There is a learning curve, but it isn't too bad if you pay attention.
