What goes around comes around.
Usually the stiffness of the wood is enough to keep it straight at the backcustard":2wd5d4ma said:......
The screw provides a point of support and actually prevents the bottom sagging as there's nothing holding it up at the back because the grooves are only on the sides and front.
Yebbut 10/20 years on with a loaded drawer and a change of humidity is when the problem could show.I've made hundreds of drawers this way without problems.
I've never seen it in use at all except when I did it myself (not knowing any better!).Incidentally, I've seen it on Georgian drawers and in Victorian instruction books so it's certainly not a new idea. But hey, they're your drawers so you use whatever method you like.
What I have often seen is trad drawers in old furniture where the back has been pinned or screwed to the bottom. This is often accompanied by a gap at the front where the bottom has shrunk away. The remedy is to remove the screws/pins and slide the bottom back into the front slot, with a bit of glue, leaving the back edge unattached. I had proof in one instance that the screws were retro fitted by an amateur - my old dad did it to a victorian table drawer many years ago before I was born - I've still got the table, minus pins/screws and the bottom properly fixed!
I've never seen it in old books but only newer ones - but in any case I don't trust the books. Not very good "good ideas" get slotted in and are repeated for evermore. The most common being the notion the DT angles should be 1/6 or 1/8 - a redundant idea which simply won't go away.
