My old door was 27 3/4 inches. The new doors are sold in a standard 28" size. Instead of trying to cut a 1/4 inch of the door (I don't have a saw guide) I thought it would be easier to pull the trim off and just redo the strike side of the door. All I need are shims right? And a level ;)
Is it better to do this vs cutting it down a 1/4 inch since if anyone wants to replace the door again in the future they won't encounter this problem.
After buying a hand plane for $10 at my local big box hardware store I started plane'ing the door, it was taking a while so out of stupidity I thought I would go ahead and use my Ryobi Circular saw to make the 1/4 inch cut.
This ended up being a miserable failure, the gap ended up being too large, what I really needed was 1/8". Instead of buying a $10 hand plane I would've been better off buying a guide for the saw, but 1/8 of an inch is still hard to cut.
Today I won for worst DIY mistake on 12/18/14. I'm no amateur, I remodeled an entire bathroom ripped up tile and put in new tile, new drywall, lights, and switches. I write all this so that anyone else who has an old house where the door size is off the standard please don't make the same mistake I did, just get a prehung door. If you have a modern house (maybe build within the last 20yrs) you can probably get something off the shelf and put it in without hassle.
