I made my leveling tool for $2.00. You need to get a 3/8" threaded rod coupler and a 2" long 3/8" bolt. Put the two together and you now can level with ease. One a level surface adjust the bolt until it just touches the blade tip on one side and then check the other side. When both sides are within 1/16" you are done, then check the front to rear level and adjust until the difference is equal to the thickness of the bolt head.
