Changing a Harbor Freight 4-speed bandsaw to one speed
Jan 2nd, 2018 at 7:48am
 
Does anyone have any information or where I can find it about converting the Harbor Freight four-speed bandsaw to a single speed? I have found that I have no need for the other speeds other than the top speed, but there appears to be a power loss because of the belt slipping from the center pulley to the top pulley. I have installed a link belt and I've tightened the center pulley to the point where I fear I could damage any bearings. Thanks for any help.

Bandsaw blade speed is determined by many factors, type of blade/tooth configuration, material. and feed rate.
If your saw is at the highest speed (HF saw is 2529FPM) and you're getting belt slippage between the speed and final dive pulleys, (you say the belt is tightened correctly) then something else must change.
You may need to slow your feed rate, or find a blade that cuts your material/s more efficiently.
How do you know that the final drive pulley is the one slipping?

IMO, too many people just "give up" on bandsaw speed. What I mean is that they find one and never change it, this is fine if you understand the other variables that need to change if the speed doesn't.
Most people seem to like a speed in the 3000 range for general purpose cutting.
