changing the size of a hollow door

[nobackwheel]

I have 2 old sliding cupbaord doors - they are the hollow type. They are coming off the cupbaord to be replaced by newer, better fitted sliding doors. I have another cupboard in a box room that needs doors putting on. It used to have doors, but were removed before we moved in! - they were definitely 'internal door width' i.e. about 40mm.

What I want to do, to save a few bob, is cut down the old doors to fit the new cupboard - is this possible?

Can I just cut down the length, then join a new peice of stripwood to the cut side? They don't have to look great, they will be painted with white gloss anyway. I could add a block in the space for the handle as well?

Is there a better way of making internal doors?

the old doors may well be made of ply or hardboard faces, with a wooden batten between them top, sides and bottom, and waffles of cardboard to fill the space.

If you cut the top off, you will probably be able to winkle the top batten off the bits of ply. Then you can push it into the hollow space at the (new) top of the cut-down door (the cardborad waffles will push out of the way) and glue or pin it into place.

These doors have almost no strength, but may hold together.
