Pressure on the outfeed side is important, especially when you have a few
inches over there to generate an alignment, BUT it's also important for your
infeed fence to be longer than your board, to keep the same support points
as the cut progresses. Also, put the bow convex side out. Then you will
have support at the outfeed fence and at the tail end of the board
throughout the cut, until the tail hits the bit. Think about it. If the
poard is convex side out you realy have alignment only until the high point
of the curve gets to the bit. At that point you have alignment only on the
outfeed side, which may or may not be long enough to keep you straight.

If the infeed fence is shorter than the board you have to work convex side
to the fence and the high point of the curve must be on the fence before the
cut starts or you'll pull away from the bit when the high point gets to the
fence. Same thing if the board is convex side out and the fence is short.
The tail will be behind the fence at startup and the board will be lifted
away from the bit as the high tail rides up the end of the fence.

With your short workpieces it should be no prob to get an 18" infeed fence
set up.

I have a router setup similar to that from the Router Workshop with the
infeed side of the fence 3 mm less the outfeed. I aligned the cutting edge
of the bit with the outfeed side of the fence so each pass should take off
3 mm along the entire length of the board. This should give a sound edge-
to-edge join boards. The boards I am using are already dressed and simply
need some edge work to enable a sound glue joint to form.

I keep pressure against the infeed side of the fence until the last 25 mm
or 1" of the board and then move the pressure to the outfeed side of the
fence. The boards are about 400 mm or 17" long. Each of the boards that I
have jointed in this fashion end up with a banana shape in the middle, it
somehow seems that I am taking off more material in the middle of the
boards than at the ends. What am I doing wrong?

Thanks for the help in advance.
