Any ideas about making a simple book case 3/4" MDF white melamine.
I was going to use biscuits but obvioulsy the glue wont stick to the
white surface
and you can't use screws as you can cover the holes up (maybe you can
tell me)
Will buscuits be strong enough? 87" tall 24 " wide 7.5" deep 6 shelves

thanks

G'day Connor,
Using 3/4" (19mm) melamine at 24" (600mm)width you shouldn't have any
problem with the shelves sagging or bowing.
My office has wall to wall book cases made from 16mm white mdf melamine
and they are stacked with books and have been for about 10 yrs. No
visable sag in the adjustable shelves. The cases are all backed with 3mm
white board. You should be able to purchase a PVA type melamine glue. I
use an "Anchor" product a division of "Bostic" and if you try to
seperate parts after the glue has cured you will tear the melamine from
the sheet. If you do not wish to use bicuits and clamps, use screws
designed for mdf and glue. Whack a white cap or matching coloured one
into the screw head and Bob's yer Auntie. If there are small kids around
the place, put a drop of super glue or the melamine glue into the screw
head prior to fitting the cap. This will prevent them from being
dislodged, or pulled out by little fingers and remove the possibility of
an ankle biter choking. I'd also recommend fixing the case to a wall as
7 1/2" deep is quite narrow for a unit that tall to be free standing. To
do this you can place a rail of either Melamine or timber under the top
or one of the fixed shelves. Another recommendation would be to back the
case so as to firm it up, hold it square and prevent racking.
These are tried and true methods, which I have been using for many
years, that does not mean that it is the best, or only method, but it
works for me.
all the best with the job

regards
John
