Topic tags/keywords: question

I want to make a couple of ash gluedup panels which will be
fixed and standing upright (for the sides of a cabinet –
some 2,5m high/0,5m wide).

My question – what sort of means can I use on the gluedup
panels to both help keep them
flat and give them some form at floor and ceiling level ?
- is something needed
- what

I was thinking breadboards are used only for panels which are
supported like table tops and here something like dadoed/dovetailed pieces
of shaped wood could be used i.e. these pieces are slid slid under and
over the panel. If this was OK, not sure whether glue is allowed
or just a screw or dowel in the middle along the width of the panel
or nothing i.e. just secure the dadoed pieces which
will also keep the panel in place ?

Must admit this wood movement business has me thinking overtime
since I have no experience – I have the feeling it’s going to
get me if I don’t get it ;) .

Are these just plain panels or part of a frame and panel side? I’m fairly new to woodworking but as I understand it most of the change in dimension of wood panels is across the long grain (that is the sides will move and get wider but the panel will not get significantly longer or shorter as the humidity levels change). something 50cm wide will probably change width a fair bit so you will need to allow for the movement. I am building some bathroom cabinets and am using frame and panel construction because it allows the center panel to move around as necessary with out affecting the overall dimension (as you can imagine the humidity in a bathroom changes a lot over). That may be a solution for you. But I am sure there are other approaches.

Hi Vjeko,
The bread board method will work. A screw or dowel in the center with glue will be OK. Only use glue to secure the dowel.
By fastening the panel in the center it will allow it to expand and contract in both directions without cracking.
There are other methods that will work but without knowing the design, it is difficult to make additional suggestions.
