Door fittings are the same. They all have doorways which, when installed, hang on a railroad system which moves them to provide access to some closet or opening. When properly sized, they line up flat and fill out the opening. They won’t shut, if they’re too wide. This is normally a problem with odd-sized openings. You can remedy this situation by trimming down more or one of those doorways to fit.
Put in a blade on a table saw. Raise into in which the blade emerges from the table, the blade from the tip of the tooth to 2 inches in height. Put in the determined dimension.
Hardware from the doorway which stop the door or may interfere with the blade saw. Measure and write down the diameters and places of any holes on top of the door which are used for pins, rollers or any additional hardware that needs to be put forth. Use a screwgun.
At which the blade will pass through the doorway, put and measure a piece of tape on both sides of the doorway and based. The blade should pass through the middle of this tape. This is to prevent chipping of this veneer.
Turn on the saw. Slowly push on the doorway holding it tight against the fence with your hand as you push against it forward . Continue pushing to get another 6 inches when the blade emerges the rear of the saw out, let go and turn off the saw.
Cut a piece of 2-by-2-by-96-inch fir to fit inside the doorway if you have cut more than 2 inches off the doorway and exposed the hollow center. Use the table saw to cut it to width and length. Put glue on both sides until it’s flush with the other side and tap it into the door’s side. Place straps onto it and let the glue dry for a hour.
Check to see whether you’ve cut off places or the holes where the hardware is set up. If you’ve cut them off, then use diameters and your measurements to drill holes. Re-install the hardware.
Sand the cut area with a hand block and 100-grit sandpaper until smooth. Wipe blot the doorway on to match the blot. Finish by spraying with aerosol lacquer.
