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,
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!
