I see good advice has been offered already. I too have an old delta saw. I have found slow down the speed and make sure it is mounted solid. I don't have much problems with vibrations. One good peice of advice on the band saw that I haven't seen is make relief cuts on the wood if possible. If the sew is set up close this will help a bunch. If you are trying to make tight turns 1/8" blades relief cuts and slow down should work.
