I bought the 14" bandsaw from harbor freight about 6 months ago. Since then I added a 6inch riser block. now I know this isn't a great saw to start with, but mine sure seems week. today I was trying to cut a few bowl blanks, they are about 5" thick and was cut a 10" diameter out of wet walnut and eucalyptus. but the saw keeped bugging down, motor was running but blade would stall out, pretty sure I had it tight enough as there wasn't any play in the blade. Any ideals or is it just a under powered saw?
