A guy I work with is wanting to make a handrail from some oak he has. It's 2" thick by 4.5 wide. He needs the total length to be 16' long. He has one piece that's 12' and another that's 6'. He asked me how I'd join the two together to get the total length. I thought about maybe pocket screws but use some that are about 2 - 2.5" long. I don't know if that would leave a gap at the top. I also mentioned dowels but gluing the two sections together might be a problem. Would you cut the two ends at 90 or 45 degrees?
How would you do this?
