I got a bandsaw for the first time 2 years ago. I’d say it probably qualifies as “midrange”, a record power BS300E
When the following are correct it works like a dream! (for straight ripping… I very rarely do any curves!)
Good quality sharp blade.
Fence set accurately.
Table set accurately.
If any of the three above are below par the performance suffers in a big way.
The thrust bearings, (top and bottom), need to be set just right as well, but the side bearings, if the other things are right, are of no consequence for straight cuts.
In my limited experience!
