Built in wardrobe - do i need to oil concealed sides?

[Adam9453]

Hello,
I am bulding a built in wardrobe for a friend using oak veneered MDF with glued on real wood edging and solid oak framed doors with veneered panels.
I plan to use Danish Oil for finishing it and I would like to know if I need to oil both sides of all parts?
The reason I ask is that a lot of sides will be concealed as they will be screwed together or behind the scribed in frame.
I would prefer not to oil areas that aren't visible as I think its wasteful of time and oil but I'm not sure if oiling one side would adversely affect it,
i.e. unbalancing it, like veneering one side of a panel would do?
Any advice would be much appreciated.

I've allways put at least one coat on all surfaces of a project even if they are concealed just to help with regards to humidity and warpage. Lots of people don't. it all depends on whether your end product is in a house with central heating and and what its made from. older building will vary with temp and humidity which could cause probs later with splitting etc.
I learned how powerful these variations could be and the damage they can cause when i bought a gorgeous original 1930's deco bedroom set when I lived in Switzerland and after having it in a modern efficient flat with CH and then moving to a house made from granite with no CH it all fell apart after a couple of winters.

I think technically yes you should finish all round, but as you describe I don't think I'd bother in this case.

Thanks for the advice guys, its much appreciated.

I may give it one coat of oil on the concealed sides to help balance it with the couple of coats that the exposed side will get.

I'm getting close to actually making the thing now!!
