Hello everyone,
I have a Bosch tabletop router table and have been trying for days to
set it up to edge-joint 3/4 stock for edge gluing. No matter what I
do the piece comes out sort of teeter-totterish. I have a split
fence
using a 1/16 shim on the outfeed side which I have tried flushing up
with the bearing, or just a little shy. No matter what I do every
piece of wood totters when I put it on a flat surface. (Tablesaw...)
Anybody have any ideas what I'm doing wrong? I've tried everything
but replacing the 1/2 shank Rockler straight-cutting bit!
Thanks

What's your setup like? Are you using featherboards or are you doing
it freehand?

Have you used a real jointer before? I've never jointed on a router table,
but I know on a real jointer you have to apply your weight on the infeed
side of the jointer, otherwise you will get a taper. Not sure if it is the
same for a router setup or not, but thought I would throw it out there just
in case. Good luck though, I'll be having to do this soon, too; so I'm
curious as to what else people come up with.

1. Don't make the shim shy of the bit/bearing, make it FLUSH.

2. Do the concave edge of the board. Depending on how concave it is, you
will take off wood at the start and wood at the end but nothing in the
middle on the first pass. Next pass will take off more at front and back,
next pass more, etc. When you take off wood all along the edge you are
finished.

I kinda suspect you have been trying to join the convex side. It can be
done but is harder as you have to make a flat area first so the board
doesn't rock against the fence; otherwise, you just perpetuate the convexity
and wind up with the same teeter-totter board.

With everything being equal and assuming smooth operation pushing the wood
past the router bit, my first inclination would be to suggest that the two
sides of the fence either aren't absolutely parallel, or the shim you're
using isn't the same thickness all the way along.

I've used a table mounted router to remove burn marks after ripping wood on
my tablesaw and even from the get-go, never encountered the problems you're
mentioning.

While it should work, 1/16" seems a little thick to me when routing on a
router table. My first suggestion would be to try a shim a little bit
thinner after again checking that your router fences are initially,
absolutely parallel.

Use a jointed board as a sled on the table saw.

Ummmm.... no, and no.

Applying your "weight" on the *infeed* side is guaranteed to produce a taper,
and a substantial one at that. Proper jointer technique involves applying
light pressure -- just enough to keep the stock on the table -- on the infeed
side *only* until enough of the stock has cleared the cutters to allow
that light pressure to be applied on the *outfeed* side, after which pressure
should be applied *only* on the *outfeed* side.

You've probably already done this, but make sure you check whether the
face of the fence is actually perpendicular to the table surface. I
picked up one of the Bosch tables at Lowes last summer and returned it
when I discovered the fence face was making an angle of about 80
degrees with the table surface.

Forget the table fence.

Clamp a straight edge to either the piece or the table (piece is
safer),

then use a pattern bit to get a clean/straight edge.

Have fun.
