Handrail is cut to fit -
Please read through the entire plan and all comments before beginning this project. It is also advisable to review the Getting Started Section. Take all necessary precautions to build safely and smartly. Work on a clean level surface, free of imperfections or debris. Always use straight boards. Check for square after each step. Always predrill holes before attaching with screws. Use glue with finish nails for a stronger hold. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain. Be safe, have fun, and ask for help if you need it. Good luck!
Once you have your handrail figured out, start by building the main straight section. The top 2x4 and bottom 2x4 should be the overall length of your straight section. 4x4 posts are attached with 3" countersunk screws and wood glue through top and bottom.
If your handrail extends more than 6 feet (check local codes for spans) you will also need to add additional 4x4 posts to meet codes. We centered our center 4x4 posts:
Now you'll need to figure how many balusters you will need.
This may take some thinking - consider the width of your balusters and spacings, and then end spacings.
Once you know how many balusters you'll need, if it is an ODD number of balusters, attach a baluster through 1 1/2" pocket holes to the center of the railing section as noted in the diagram.
If you need an EVEN number of balusters, the center will be a spacing. So find the center, and measure 1/2 the distance of your spacing off the center. Attach a baluster here.
