I'm looking at re-making my clothes closet to a book shelf unit. I've
been contemplating putting up some 3/4" MDF on each side and running
lengths for the shelves going down. (The span is approximately 3').
I've never used a routing system before and am looking for
recommendations for how deep the cut should go for the 3/4" shelves to
slide in? Would simply glueing them in make a strong enough bond?
Thanks for any suggestions,
The usual depth would be 1/4 inch (I am assuming that you mean the depth of
a dado cut). You would glue them in the dado. By the way, isn't 3 feet
more than a bit long for MDF?
MDF is heavy but weak.
Back to the original topic, I'll second the 1/4" deep dados, but I'd
also agree you'd want something other than MDF for your shelving
material. Solid hardwood (3/4") should be fine for 3', or even strips
of pine under MDF as supports should work.
Alternatively, if you didn't want to rout dados, you could cut a bunch
of 1"x1"xshelf depth" strips to use as cleats, and set your shelves on
those. You'd still need something to support the MDF in the middle,
but that's another option for the sides.
Good luck and have fun,
I agree with Jim that 3/4" MDF is a bit weak for a 3' span-- especially
for books. I'd use a centered stile in the back and front-- about 2"
wide made of pine or even 3/4" plywood dadoed the same as the sides
that will accept the shelves. , ( a brace running back to front would
be even stronger-) When assembling, the front stile in the center
would be the last thing to go on.
That should work.
The OP will find that MDF breaks very easily. It also may crack when
nailed. It also does not hold screws well.
Otherwise, outside of its appearance, it is fine stuff.
(In your house that is).
