There has been a few posts recently regarding adjusting a jointer and it got me to thinking. One problem that caused me some frustration occurred after several years of use when one of the tables started to sag. And since the tables we no longer co-planar I started having problems. Identifying this as a problem was not quite as quick of easy as I thought. But, what if, You were to take one of those little $10-15 HeNe lasers (the red light ones) affix it to a block of some kind, set it at one corner of one table and aim it back to a ruler stuck to a block at one side of the other table. Record the height. Move the laser block to the other side and then the front of the table repeating the measurement each time. Unless all measurements are the same your tables are not co-planar. Seems quicker and a lot cheaper than getting an expensive straight edge. So will it work? What do you think? Cheers, JG
