Wood for in wall cabinet
While I've done standalone wood projects before this is the first time I've integrated into my home. I've got a space in my wall with measurements of 91 5/8 H x 16 1/2 W x 19 3/8 D.

Not worried about color because it will be hidden, more concerned on what material to use. Of the precut materials only MDF has the diameter of 19 3/8. I found precut and pre drilled melamine with right height and width but not diameter (only 15 3/4).

Do I get two boards and join with glue and biscuits?

Insight is very appreciated.

if that's an exterior wall, you will have deterioration from moisture. it will, of course, displace insulation there. you'd have to wrap it with seamless plastic and red-tape it to the existing vapor barrier.

I wouldn't use MDF myself, but then I'm a red-oak kind of guy. oak, you can biscuit and keep strength, or use oak plywood for the back. MDF, as soon as you mess with it, you weaken it. it's only fibers and glue, you know. the melamine coated stuff is going to have a visible seam, and it will erode at the seam in time.

double plus the cost, but consider an in-wall cabinet as a lifetime thing, so ought to do it to last IMPHO.


sig: if this is a new economy, how come they still want my old-fashioned money?

What swschrad said about exterior walls is correct. If its interior I would use a cabinet grade of American made plywood (if you have a ton of patience and help use the Chinese stuff). Plywood is much more stable. You'll pay more for the American stuff, but it's really more stable. You will have some place that sell many varieties of wood. Cabinet plywood is graded by a letter on one side and a number on the other. For example 'A' '1' has the best veneer on it. 'D' '4', is more of a paint grade. Hope this helps.

FYI, for those of you who want to know more about lumber and plywood, this link is an excellent resource, they used to put this info in a book and I guard mine like a hawk.
