Folks -
I have PC biscuit jointer (type 2) and it's not quite a year old. I know
from surfing around here, that there is some sort of shim for the type 1's,
IIRC.
The problem? I am building an aux 90 degree fence and I've ended up with
some slop. Using the base as a reference in making my cuts the two pieces
should line up exactly, but after I got everything cut, I discovered that
the vertical leg of the 90 was set back from the base by about 1/32+ over
the length. I used the TS table and had everything all solid and square, so
I thought, but no such luck.
This isn't the first time I've had trouble with vertical creep of the
biscuit slot and it keeps cropping up. I don't have any obvious slop or
wobble in the cutter, so what is going on? I specifically purchased the
type 2 to avoid whatever problem the shim set up attempted to solve.
Here's what I have ended up with, if you'll forgive my ASCII:
| |
| |
| |
| |
| _ |
| | | |
|__| |_ | *
* _ _______________
| | |
| |_|
|______________________
The upper asterisk shows that I referenced that corner to the base of the
biscuit jointer, the lower asterisk shows I referenced the upper, outside
corner of the lower piece. The slot, therefore, should be exactly the same
height/depth from the reference points, but it aint!
What gives?

John -
There would be no reason to expect that these parts would line up, if
I understand what you are saying you did. You should have had the
vertical piece in your drawing positioned with the left side from your
drawing facing down, to match what you did with the horizontal piece.
As I understand what you are saying, you instead had the right side
facing down. Whay would you expect those slots to match? Those are
different distances.

Dave,
I use about 10,000 biscuits a year, don't go nuts trying to get the slot in
the middle of any piece of wood. Learn to reference...that's all you need
to know how to do...!
FWIW, take a 3/4" piece of wood, place that 1/8" spacer under your joiner,
cut a slot, now turn the piece of wood over and cut a second slot. Now you
have two slots centered perfectly on the wood. (BTW this works on any
thickness of wood.)

This is common with most every joiner. Learn to reference properly and you
don't need to shim in the typical joint.
BAD Said>I've been bitching about the crappy fence on my 557
The "fence" has nothing to do with this particular joint. All cuts should
reference off the same point and all material will be laying flat on the
bench and the "fence" isn't used. The bottom of the joiner is used in this
joint for reference purposes.

Bridger -
Right you are! My illustration is worng... The single asterisk is the
reference for both parts... Typing ASCII art makes my brain hurt.
I am building Jim Tolpin's "Universal Rip Fence" from his book "Tablesaw
Magic" and this is the vertical fence attachment for the Bies.
The vertical fence features a cuppla threaded inserts and t track in the
vertical face for fixtures, sliders and featherboards, etc. The alignment
of the fence is dead on at the end of the fence, but it is misaligned
slightly at the head.

What I am saying is, regardless of my illustration, I *know* I had the parts
properly aligned and ref'd when I made the cuts, because I *have* made the
mcsnake of getting the cuts reversed. I've had this same problem in making
a simple biscuited edge joint in gluing up boards into panels. Invariably,
I will have a vertical misalignment of the boards over the entire panel, say
16 x 24, of 3/32 or 1/8" (total, top & bottom) . As I see it, a properly
cut biscuit joint *should* be dead on vertically as those biscuits snug up
pretty quick.
I hope I've made myself clearer... Thanks for pointing out my twitchy
finger.

welcome to my world, John. I've been bitching about the crappy fence on
my 557 but other folks think it's the greatest thing since sliced bread.
I've learned to "baby" the damn thing when cutting slots, so that they
come out pretty close to perfect. Had I been a wiser man I would have
purchased the Makita or Lamello...

if I'm reading your ascii right you are referencing backward. your
asterisks should meet.
Bridger
John,
First, if I was going to make the joint you show and wanted the LH face of
the vertical board to align with the end of the bottom board, I would have
referenced the slot from the LH face of the vertical board (the opposite
face from what you show). In other words, reference the cut from the same
side of the two surfaces that you want to be perfectly flush. That way,
even if the two boards aren't exactly the same thickness, they will still
perfectly align on the reference face.
The other problem I have experienced with my PC joiner is that, when I slot
a 3/4" thick board while it is laying flat on a benchtop, the base of the
joiner will rest on the benchtop and leave the fence about 1/32 inch above
the top face of the board. This raises the slot about 1/32" above the board
center. To prevent this, I have learned (the hard way), to always shim the
board a small distance above the benchtop (or extend the board over the edge
of the bench) to make sure that the fence references the biscuit slot from
the face of the board - not the benchtop. Since I became aware of this
problem, I haven't had any more trouble with mis-aligned slots with my PC
joiner.
Better luck next time,

John-
I get alignment problems with the biscuit jointer too. funny, wasn't
the idea of that tool to make alignment automatic? : ^ )
usually I can trace it to operator error- things like failing to
notice that the board had a little bow in it so the reference surface
wasn't sitting flat, or not holding the fence tight enough to the
board. I reference from the bench top as much as I can- and if I were
to fail to notice twist in the board I could get misalignment from end
to end.
having a jig come out wonky really sucks- you can never quite trust it
to make straight cuts, even if the misaligned part isn't critical....

OK, It is important to be sure that your plate joiner is hanging off the
end of the board with it not touching the work surface. Basically you
should be sure the wood you are cutting is at the edge of the work surface
and the joiner is hanging from the wood and not accidentally setting on the
work surface also. If the joiner rests on the work surface while cutting a
slot you may be cutting the slot too high and throwing your alignment off.
I had this problem and it took too long for me to figure what I was doing
wrong.
Also, IIRC the preferred ones are the Type 1 or type 3. I believe the type
2 was the one that was changed to satisfy DeWalt and the Type 3 fixed the
fence problem that the Type 1 never had.

this could be a genuine post ?

to take your comment a bit further, let me mention that I've placed
