I just bought a PC555 at an auction.
It came with a bunch of #10 biscuits, and I have been playing with it.
Presumably the cut depth should be set so that the two pieces just come
together with the biscuit inserted. Yes?
Even then, there is an awful lot of play; the biscuit moves around pretty
freely. I know it is supposed to swell with the glue, but it just seems too
loose. Is that normal, am I doing something wrong, or is my jointer or
I didn't notice that there was no dust port. Any suggestions for minimizing
the mess? (I guess I got what I paid for...)
They should slide in without any play they will vary depending on many
things, biscuit subject too humidity will make them tight, not hold the
biscuit cutter tight will give a wide cut and the fence not parallel to the
cutter will make the slot large also.
Set the depth of the slot a little deeper than the biscuit
Woodworking is messy get used to it.
When joining 2 pieces with a biscuit or with dowels or with any form
or joinery the matting pieces must fit tight, of course. Your biscuit
must not restrict a tight fit so your depth of cut must be sufficient
for the biscuit to lay in the wood and yet the joint must close
The reason for all that side play in a biscuit slot is for ease of
joining the matting pieces... dowels, by comparison, are a tight fit
during the process of lining up the dowel pins with the holes... this
is alleviated with biscuits because you have some side to side play in
the biscuits slot.
Sawdust is the by-product of cutting wood with any tool that doesn't
have a means of catching it in a bag... plate joiners, routers, finish
sanders and the like all cast sawdust... sawdust, to a woodworker, is
manna from heaven.
What you do is after you made the slot cut, insert the biscuit, using a fine
pencil, draw the line, then turn the biscuit around, draw the line again (on
the same side), then pull it out and measure the line. It should have
1/16"th space. Do you know what is being asked you to do? That is for #20
biscuits, with that, the #10 should follow falling into correct settings.
Also, you may want to look at it and see if the bits are sharp, if not, it
may not be cut correctly. Check if there is a play (first, unplug the cord,
then pull the body in and move the blade sideways), if there's a play, then
something need to be tighten.
It is called a PLATE JOINER. A commonly error name is "biscuit cutter." A
jointer and plate joiner are two different category.
PC has different settings for the different biscuits (20/10/0) but made need
adjusting (do the pencil trick as said previously). That takes care of the
side to side play. Up/down may be a function of your biscuits. I stick to
Since we're extra anal this morning, I'll point out the following:
I think one manufacturer, possibly Freud, copyrighted "Biscuit
Joiner", so most everyone else uses "Plate Joiner".
Either is "correct".
They look like they do the same thing to me. <G>
Which way ? The biscuit should be a tight fit (narrow thickness) but
should slide along its long axis quite some distance. A biscuit only
locates in one axis (thickness), should have barely adequate depth
(short width), and is deliberately flexible with the long axis, to
If you're sawing an over-width slot, then check for a damaged or bent
sawblade (cheaply replaceable) or (sadly more common) worn out
bearings on the machine. Failed bearings are usually a scrapper,
depending on the ease of dismantling and maker's spares position.
Bearings are just a standard item from any bearing dealer, but you may
have lost the arbor too.
