No kidding... I haven't had that happen but once. Are you seeing this
on a particular kind of wood or some size of glue up?
I know there are those that have this problem all the time, but I also
know that you undoubtedly buy the good biscuits and are careful (as
you cautioned above) about the installation technique.
I may not have this problem because 1) I am lucky! or 2) I dry fit the
biscuits before I put them in the glue. If they don't slip in and out
with just a little friction, they don't get used.
I only use the PC biscuits (I see you use Lamello) and quit using the
"bag o' biscuits" when a great deal of them didn't fit right, weren't
****pped properly (sealed containers) and they were crumbly.
Remember when companies like PC had actual, live tool reps, not 23
year old guys with degrees in marketing that simply filled out
customer orders?
I went to a "PC Days" thing they had at Woodcraft many, many years ago
and he told me their were three things that screwed up biscuit joinery
(certainly not saying here that you are doing any of these!):
- Folks don't use enough biscuits (at 0.03 a whack, that one made me
LMAO)
- They don't get the depth right (addressed by you)
- And they don't store the biscuits properly
According to the guy, the reason sPC went to the little clear bottles
was to cut down on breakage, but more im****tantly keep the moisture
out of the biscuits. Swelling of the biscuits was a known problem and
PC apparently got a ton of them back as returns.
His opinion was that if you have to tap a biscuit in, it is too
tight. He swore that tight biscuits (don't even go there,
buddy... ;^) ) were the problem that caused their shape to be
reflected through the wood due to their expansion when hit with the
glue.
Your thoughts?
