HOw do I adjust the tables so I do not get a snipe?
Adjusting a jointer to relieve snipe can be trickey but here are a few procedures that will help.
-The two tables on the jointer are adjustable, the front (infeed) is what you adjust for cut depth.
- The back (outfeed) needs to be the exact hieght as your knives
The outfeed needs to be adjusted first
-using a straight edge on the outfeed table adjust it so that when you turn the head (counter clockwise) the knives just touch the staight edge (NOTE** all the knives should touch the straight edge the same, if not your knives are not set correctly) This is your most important adjustment, if the outfeed is to high or to low it will cause inconsistant jointing.
-Now that the outfeed is trued up to the head you can adjust the infeed table, using the straight edge align it so that it is perfectly lined up with the outfeed table (not touching the kinives) Your jointer is now at ZERO
You can now adjust the infeed for depth of cut, Start by lowering the infeed a very small amount (1/16 of a inch to start)
The biggest problem I have seen is that people try to cut to much at one time, it will work alot better if you take several small cuts instead of one deep cut.
Also- getting the knives set perfectly in the head is a key to success, if this is not happening you WILL have jointing problems. ALSO if the knives are not sharp they will pull the material down causing snipe.
I really hope this helps and if you need a visual aid try looking it up on you tube.
I have used my jointer for numerous different projects, Here is a cool one for tapered table legs.
Take a piece of square stock (like 2x2 ) about 3 feet long, make a mark about 2 foot up and wrap a piece of tape around it at the mark.
now make a mark (we will call it a stop mark) on the fence of the jointer by the head.
with a pencil and number the edges on the 2x2 (above the tape so you dont joint them off)
turn on jointer and run side 1 until your tape is at the fence mark, carefully lift 2x2 and do the same to the 2 side.
only joint the #1 & #2 sides, run several more times and you will have a perfect tapered leg.
