I'm making a drawer unit with a pine dust frame and a poplar face frame.
How differently do the two woods move seasonally? Can I glue the entire
mating edge or should I leave the ends free? The climate here varies from
mostly low humidity in the summer to very high in the winter.
The question (I think) isn't really about the differential in the
woods but rather that both woods are running their grain in the same
direction. I have to admit that I'm unfamiliar with "dust frame" so I
can't give a direct answer.
IF the dust frame is like the toe kick then as it runs across the
front FF you have no worry as the bottom rail of the FF and the dust
frame are ong grain on long gran and most of the movement is cross
grain so I don't see a problem.
However, If I have this right, then I assume on the sides, the dust
frame is running across the side panel, then regardless of different
or same woods, you need to account for the movement in the panel
I could be way off base here but I am still reeling a bit from the
Texan thing about leading a horse to water and the image of that
second guy sucking.
Will provide you with the T/R percentage values. As dust frames are
normally that - frames to control drop from above, they're attached forward,
float aft in vertical solid wood carcasses.
Neither will give you problems, unless you use fresh construction grade
lumber immediately versus letting it drop moisture prior to use.
How wide is the face frame and what will be the grain situation where they
join? If you don't have a cross grain situation, and any likely
expansion/contraction will be in the same direction, you will most likely
not have a problem. Even then, if the face frame is narrow, say 1 1/2" or
so, you will probably still be OK.
FWIW, and not that it matters for your project, but I have had better luck
over the long haul making dust frames (rails, stiles, panels).entirely out
of a good grade of plywood, instead of solid wood. Although I've had to edge
them a time or two, it was less expensive and provided better dimensional
Thanks for the responses so far.
This drawer unit is going under a cantilevered hearth that is about 10" from
the floor. There will be three drawers side-by-side about 17" by 15" and
about 7" deep. The dust frame is made of 1X4 pine ripped from wider boards
and the face frame is 1X2 poplar. They will be joined long-grain to
long-grain. I'm debating whether to rabbet both pieces or just edge-glue
and pocket screw the dust frame to the face frame. Any thoughts?
I wanted to make the dust frame out of plywood for stability but the store
only had some crappy stuff that was pretty beat up and not very straight.
The pine, on the other hand, was VERY straight. Unusually so for pine.
