I have a hollow core door that I purchaed . The purchased door width from factory is 24 " and the door opening is also 24 " (original pre-hung hollow door measures at 23 3/4") . What is method recommended to trim off approx. 1/8 " from each side ?

Rent a power planer and set a straightedge along the side to act as a stop. You could possibly use a power saw with a plywood blade and then sand the edge. /8 removal still gives you plenty of edge thickness.

First choose would be an electric plane. On lock side, adjust plane so u get a slight bevel, about 7 degrees, on side that swings toward door stop.

Second choose a table saw. Will have to sand edge after cut.

Third hand plane.

Good luck

Hi Brian

Sorry about my post. Yours was not up when started

Happens to me too. At least we're on the same page. I was going to repost with an angle cut but I'll leave that up to your post. Good old minds must think alike! Brian
