Few extra tips
King cobra, awesome tutorial. You won't find this professional info in any book or any tutorial (This is top secret shit!).This is the only tutorial i've seen that shows what I consider the correct way to set up a table.
I have a couple extra tips, that were not shown in the tutorial and are imperative to successfull leveling. Unfortunately the carpenters level is not a true straight edge, and can very quite a bit from end to end. When you are at the stages of using the machinist level on top of the carpenters level make sure you calibrate the machinist level and carpenters level as a single unit. If you don't do this you will get VERY funky readings that don't make sense, and you will probably just end up shooting yourself or somebody else. Just as you would normally calibrate the machinist level by itself, you MUST calibrate the machinist level and carpenters level as a single unit. So put machinist level on top of carpenters level and adjust machinist leveling system, turn the machinist level and carpenters level as a single unit 180 degrees and adjust. Repeat until no variations. And make sure when you are doing your leveling to always keep the machinist levels front face aligned with the same face as carpenters level as it was when calibrated. Also when you start using the machinist level without the carpenters level, you must recalibrate it. If you do alot of tables invest in a straightedge, or have a machinist level for use by itself, and one for use with the carpenters level.
If you don't want to fork out cash for a starrett, you can get a cheap chinese machinist level from ebay or Grizzly for about $60 for a 10 inch or so. They are a pain in the ass to calibrate compared to the starrett, but are just as accurate and work just as well once calibrated. If you get one off of ebay the one you want to buy looks like the machinist level on the grizzly site, and it is the same. If you buy one off of ebay, it will come with Chinglish instructions which make no sense whatsoever. They have the instructions in english on the grizzly website for that level. BTW the screw on the bottom is useless, and all of your adjustments will be made with the spanner wheels. If money isn't really an issue get the Starett.
For the carpenters level I HIGHLY recommend a 72" Swanson box level that is sold at Lowes for like $50-$60. It has a large enough depth that the machinist level sits well on, and is the same one pictured in King Cobras tutorials. Most other levels sold don't work very well for doing this. (the top and bottoms aren't usually machined, and skinny to the point that your machinist level has to be centered just perfectly or it will want to fall off because of the vgroove in the machinist level. NOT GOOD!).
If you take Cobras steps, my steps, take your time, be anal retentive, and dont take shortcuts, your table will play better than any table around.
Good Luck
