Glue and Screw Method
This is the easiest method for a hollow base newel installation.
You will need 4 to 6 screws, good carpenter’s glue, and wood filler. Trim head screws work well, because the heads are small and require a small hole, so less filler is needed in the hole. Remember, the glue will be very strong once it dries, the screws are mostly for initial stablility.
- Once the newel is cut to length, set in place and check for plumb.
- Mark the very corners of the newel so it can be set back in the exact same location.
- Remove the newel and put a bead of a carpenter’s glue where the newel base will set.
- Set the newel back in place on the glue.
- Drill holes at an angle throught the newel base into the floor to accomodate a square drive trim head screw. The closer to the corners you put the screws, the more stability they provide.
- Once all the screws are in, check for plumb. If the post needs adjusted, back out the appropriate screws, and use matching wood shims to shim it plumb.
- Fill the screw holes with a wood filler that will match the newel.
Fill and Mount Method
This is the second option for a hollow base newel installation. It results in a lot more glue anchoring the newel in place than “Glue and Screw Method”.
- Cut piece of 2 X material that will just fit inside the bottom of the newel (snug but not tight).
- Cut the newel to length.
- Take the scrap cut off and set in place where the newel will be mounted.
- Drop the 2 X material inside.
- Hold the 2 X in place and remove the newel cut off.
- Mark the perimeter of the 2 X and remove.
- Using carpenter glue, glue the bottom of the 2 X and nail or screw it down, making sure to not split it.
- If you want to stack another piece or two of 2 X onto the first one, you may. The higher this filler is, the harder it will be to plumb your newel if necessary.
- Once the 2 X piece is down, you can then glue the edges as well as the floor where the newel base will be setting, and set the newel in place.
- Screw trim head screws at an angle into the floor, or straight into the 2 X filler to anchor the newel. You may choose to use a 15ga trim nail through the newel into the filler also.
- Be sure the newel is plumbed, then nail it in place.
