Bonjour a tous et a toutes
Last year I wrote a short post about how to flatten a « thin » piece of wood
Now today I will show how to flatten a panel.
The problem is this:
and this is the left side of this (in red circle):
As usual, before doing anything, you have to think twice or even thrice, what could be the best solution.
Panel are usually assemble to edge grain , and most probably with live sawn boards as the face grain side curved.
OK, so one solution would be simply insert glue between the curved part of the panel and the side and put a clamp . But by pushing by hand you can see there is quit some pressure, so this would not work or at least not last.
So the second solution would be decrease the tensions in that board by making some grooves in that opposite side of the panel, the one which is on the opposite side of the veneer.
With less tensions in the board and a good gluing, this shall be fine
So first you have to remove the top and background panel,
and then remove the panel you want to work on:
Once again, you know that this is hide glue, so you can soften it either with water or either with heat, to be honest I worked little bit with force too.
Once I opened this box, I notice that the solution I choose , had already been used,
as you can see on the photo below, some grooves are already there.
Which means despite the grooves, the wood still curves, so you have to use a more radical solution:
First, if possible increase the depth of the grooves and the number too.
Then little by little, flatten the boar, easy easy, be careful to no rip the veneer on opposite side,
once you reach your goal, maintain the fully flat position to get free hands,
as below I hold it with clamps.
Then start to dig the space to place the piece of wood perpendicularly to the face grain of the panel. I used chisel and mallet.
To be honest I took this piece of satiné cause it was approximately the size I needed and I did not need to do any cutting.
Like this you will assure flatness to the panel
Now before you place your piece of wood, think about the drawer that should slide and need a
passage, so decrease a bit the thickness of the piece where the drawer is supposed to slide
Now it seems to fit properly
As usual, I used the fish glue.
Let it dry
Now it is not done yet,
you have to make a proper gluing,
and remove all the old glue to have a good grip power once glued again,
I used the same technique as usual, described here:
Once wood is clean and dry
you can go for the final step
