Default Re: Warped 'fibreboard' (?) on Avominor

In the past I've used a steam-iron on such fibreboard radio card-backs: give the part a good steaming - both sides - then when it's steamy and still too-hot-to-touch put it flat under a foot or so of heavy books to press it down.

Leave for a few weeks!
