   you'll need some straightedges, check that the wheels are aligned, check each wheel for trueness, check that the pulley is where it should be- if it was shipped ready to start up, the motor weight may have caused misalignment. Check for any any kinks in the blade, perhaps it was brazed poorly and needs to be filed. Check for upper and lower guide blocks are in the same plane.

   Would'nt hurt to check the belt too.

   The wheels wouldn't "warp" unless they were dropped or in a fire.

   It would be hard to create serious vibration with just a tire swap. Did you run the saw before the swap and if so, how did it work?

   If the machine has been sitting for a while, the belt is likely to need replacing. Buy a good-quality machine belt from a real industrial supplier (e.g. http://www.mcmaster.com or local) rather than a hardware or auto parts store.

   Beyond that, it's process of elimination. Carefully spin each wheel by hand, making sure that they're on properly and no shaft is bent. Try running just the motor, then run the motor and one wheel with no band, etc. Make sure the band isn't kinked.

   Good luck!

   Hi planespoken,

          Are the new tires glued on or stretched on ? If they were stretched on it could be that there is more rubber on one side of the wheel than the other. Wedge the wheel so it is stationary and work a screw driver under the tire and run it around the circumference to " equalize the stretch " . This was a big help to me when I changed my bandsaw tires.

   Try replacing your drive belt.  As a high school shop teacher, I have noticed that after a bandsaw sets over a summer, it will run rough for a few days due to a set in the belt.

   You ask "Or could the old blade itself be the issue?".  If this was stored under tension, why not.  Take the blade off and examine it. 

   You left out two bits of information that you should discover.  1)  Is the vibration more, less or about the same as before you tuned it up.  2)  Does this vibration exist if you run the machine with no blade.

   As for your first question, I have never heard of aluminum wheels warping.  as for your third, I am not familiar with that model bandsaw and the build quality, but if the blade had been overtensioned, check the axle and the and wheel mounting bolts.

   Take the blade off and run it.  Does it still vibrate?

   Take the belt off and run it.  Does it still vibrate?  (Ouch!)

   If it doesn't vibrate with the blade off, that seemingly eliminates belt or bottom wheel problem (except for out of round, of course).  Spin the top wheel and make a mark at the bottom when it stops spinning.  Spin again and note if the mark is at the bottom, again.  (Ouch!)  If the mark always ends at the bottom that indicates an out-of-balance wheel.

   You can check for out-of-roundness wheels by spinning them and holding a bit of wood or ruler close to the circumference of the wheel and note if the wheel touches the wood at some one point. 

   If it vibrates with just the belt that pretty much indicates the belt has taken a set.  It may, as mentioned, smooth out with use, but I'd replace it.  I like the power-link belts available from McMaster and other suppliers.

   YMMV, of course.

   You should also try posting your quesion on the Inca tool users group on yahoo.  Lots of information specific to inca tools there.

   One Incra bandsaw I know of had three wheels. I believe some blade manufacturers make blades especially for three wheelers.
