Had a weird gap issue on a built-in and tried something my grandpa said once
I was fitting a cabinet into an old, uneven wall in a house in Bellingham. The gap at the top was almost 3/8 inch and I didn't want to scribe a huge filler. I remembered my grandpa saying to use a heat gun on the back of the plywood to make it bend. I clamped one end, heated the back along the top edge for about a minute, and gently pushed it into place. It held the curve perfectly after it cooled. Has anyone else tried bending plywood with heat for a tight fit, or is that a bad idea long term?
