Hello everyone…... its that time to wipe the thick layer of dust from my shelves, drawers and tools. i do this at least once a month. during that time i blow all the dust out of the shop with my leaf blower. i take all of my important tools apart and replace brushes, belts, bits and blades. i oil, grease and lubricate all moving parts and bearings. the tool that i pay most attention to in the shop is my 10” cabinet saw. i am constantly checking to see if the blade is square to the miter slots and fence parralell to the blade. i keep my 0 degree and 45 degree stop carefully tuned. my cabinet saw is verry important to me when producing precision work.
My saw is a 2007 10” craftsman proffesional cabinet table saw. it has treated me verry well however recently i have had a few problems. i have fixed most of the problems already. there are two problems that i just cant seem to fix. i dont even know whats causing it.
PROBLEM 1- by far the most important problem. as time has passed i have noticed the saw begining to shake. in the begining the saw was only shaking when powered up and when powered down. the trembling was only being caused at a certain RPM. once the saw got up to full speed it would stop. i could not identify the problem and as time went on the shaking got worse. it now shakes consistantly. it seems to only be shaking around the motor where the belt drive wheel is. i replaced the belt cleaned and lubricated in and around the pully area. the problem still existed. i then checked both of the pully wheels with a dial indicator. they seem to be fine. they dont seem to be bent or lopsided. just after cheking the pulleys i put the belt back on and the shaking continued. to find out if the motor was shaking internaly i took everything appart and pluged the motor in by itself. when i turned it on it ran like a champ. it ran smooth. i cannot figure out what is causing the problem. it really doesnt affect any cut that i make with the tablesaw. the shaking seems to be confined to the motor and surounding parts. even though it does not affect any cut i make. it concerns me because a saw should not sound like that. as i said before it still seems to be shaking more violently at low RPM’s. when powered up and down
PROBLEM 2- allitle less concerning to me but definetly a priority as it does affect certain cuts i make. when the blade is low to the table and checked for squareness to the miter slot its perfect. within .002”. as the blade is raised higher and higher it becomes more and more out of square. as much as .012”. i tried changing blades and the problem still existed. as i hardly ever need to raise the blade all the way this problem isnt affeting me very much iether but as i said before a saw shouldnt be doing that. lol.
any help at all would be great. i know that there are allot of woodworkers on lumberjocks who have a tremendouse amount of knowledge when it comes to tools. i might need to give more imformation on the kind of saw i have but i hope that i have provided enough information for one to get an idea of what problems i am having. all i have to say is. should have got a delta or powermatic. lol
