A while back I bought a PC biscuit jointer and have just gotten an

questions:

1. The biscuits seem pretty loose in the slot. *I can move the boards
laterally a 64th or so. *Is this normal?

Yes. I have a can of biscuits that is several months old. Some if the
biscuits will be tight and some loose. There will some variability in
moisture content from biscuit to biscuit. (this is what I have found).

After you add glue they will swell significantly.

*I thought they'd be more
like dowels and be quite tight. *I know the idea is that they expand
when glued but the slop isn't giving me much confidence. *My plywood
is somewhat warped so there is no way the biscuits are going to hold
the two pieces laterally. *It seems I'm going to have to make some
cauls this weekend.

YES! Use wax paper so the cauls don't stick.


2. Is the PC jointer supposed to sound like a coffee grinder? *

Don't know this one, I own a DeWalt.


I would
have expected the sound from HF, but not a "high end" jointer like the
PC. *I can't feel any slop in the bearings so I don't think this
accounts for any slop, but thought I'd ask.

Thanks.
