Sloppier in what respect?

There's enough play in the biscuit slots, and enough variability
in the thickness of individual biscuits, to allow for noticeable
misalignment in an edge-to-edge glue-up, enough to leave a ridge
that's too big to remove with just a few passes with a card
scraper. I found that I can get better alignment, faster, without
the biscuits.


I understand how that can happen but I've not really had problems with
it. I've been using Porter Cable biscuits and keep them in a pretty
stable environment so they don't swell.

I did once use a bag of generic biscuit and found more variation though.

I used PC biscuits and PC cutter and found and had the same problem.

Same he PC tool and PC biscuits.

It's back in the box with just a little dust on it.

I'm still using mine, though. Just not for edge-gluing panels.

If I couldn't trust it to align flat panels to each other (with the
help of clamps and cauls), I figured there was no point in even trying
anything more complicated. There are too many other joinery
techniques to bother with it anymore.
