Do you see any problem putting decking type screws between slats when making a cutting board. This would be done to help hold it together while glueing and for added strength and resistance to bowing. I seem to have trouble when I just clamp everything. It gets bowed. my plan would be to pre drill holes and screw together 4 slats at a time (and also glue). Then I would attach these sub assembles and glue them together somehow. Maybe inserting dowels for extra strength. Just been thinking. I am using maple.

It would probably be better to first identify _why_ your cutting board
bows when you clamp it. Could be the material is too thin, or more likely,
your boards aren't square.

When gluing multiple pieces, 10+' you have to apply a lot of pressure to
insure all joints get squeezed tightly shut. This will make even BESSEY
kbody and cabinet master clamps to bow.

There are two reasons I can think of at the moment why your glueups bow...

1. The edges aren't square

2. Your clamps aren't set properly. If, for example, all the clamps go
across one side of what you are clamping and if the pressure isn't at the
middle of the edges, tightening the clamps will bow the wood. The easy
way to avoid that is to alternate the clamps, top and bottom; i.e., one on
the top, next (a distance away) on the bottom, next on the top, etc.

As you tighten the clamps, you should use a straight edge across the
boards to assure all are flat; if not, you can tweak it by
tightening/loosing clamps on the appropriate side.

As far as the screws go, I see no problem in doing so, just use something
that doesn't rust.

One possible cause of bowing could be your clamping pressure may be
too high. To counteract the bowing, cauls positioned above and below
your work piece and perpendicular to your clamps could solve the
problem.

FWIW, when I was in high school we sent the initial glue-up
through the jointer and planer to take care of Minor slippage.

What thickness ? of maple.
.. others mentioned clamping pressure ..
... perhaps more of a problem with thin stock ?

stainless steel screws if you really must use screws.

I would be concerned about rust, and with "decking type" screws
I'd be concerned about what they're plated with (which most
likely should not be anywhere near food).

If alignment is the issue, I'd use wood dowels.

I've been thinking about dowels since about the first post... No chance of

Not saying that rust would not be bud, but would rust really be a problem?

The screw is there only to assist with glue up. If it rusted what would
it matter?

Just food for thought. I often use 23 gauge pins for preventing creep
and they have never been an issue.

Yes, since they are totally unnecessary.

If you want to reduce "creep" in your glue up, break there job into
multiple glue ups.

If the total glue up is 16 strips, then do 8 glue ups of 2 strips
each.

When dry, do 4 glue ups of 4 strips each.

When dry, do 2 glue ups of 8 strips each.

When dry, proceed.

You have 16 strips glued together with minimum "creep" while
making only a single joint with each glue up.

That's something I learned early.
Now, I often glue up just wide enough to fit through the planer, then
glue those together. It's a lot fewer seems to scrape.

Bad idea. If the stock sides are parallel, the parts could be creeping and sliding. You could try sprinkling a tiny bit of sand between the boards to prevent slipping. Also, as has been said, use cauls to hold the top and bottom flat.

I am currently building 6 cutting boards with 20 pieces of maple each. I
simply glued 5 together and clamped, then I glued 4 sets of those together.
I had very slight slip. This was pretty fast for me, I glued up 22
groups of 5 in less than 2 hours.

You could use screws but that is going to take significantly longer and
will be a potential hazard if you need to trim after glue up.

Use clamps on top and bottom to guard against bowing.

I made a half dozen sets for Christmas gifts. Got the idea from
Woodsmith (I think).

Started with 5/4 maple blocks and made several templates with different
radii. Marked the blocks and bandsawd the curve. Cut a bunch of strips
of 5/4 wide by 1/16" thick cherry and walnut on the TS and glued and
clamped between the bandsawn curve. Repeat a bunch of times. Then
trimmed the block square on the TS and glued walnut banding around the
perimeter. Bandsawd the four coasters 1/4" thick from the block.

People ask "How did you do that inlay?" :-)

I've made those before, they are a good seller at the craft shows.
Labor intensive compared to a regular cutting board, but similar to
regular projects. What I didn't like was waiting for the glue to dry
after each 'inlay' and of coarse cutting the bugger in half at the
bandsaw (just seems like I'm destroying it).

Try just gluing it like Leon said. If that doesn't work, screw it.
