The Bridge: Drawboring the Hand Rails

I'm discussing this out of order because I want to remember--years from now when I am too old to do anything except read my blog posts--how I attached the rails for the bridge. The idea is called drawboring,

In case you've forgotten, old man Fred, you silly old man sitting there doing nothing, the hand rails were mortise and tenon (look it up). Yes, I'm talking to you.

You drilled some holes into the posts, and then you inserted the rail tenons into the post mortices and marked the locations with a pencil. Normally you'd just drill through the post and the tenon, but with drawboring you want the tenon hole to be slightly off center. This way, the dowels will pull the hand rails up tight when you push them through. Do you remember any of this? Probably not.

Of course, to do this you need to make the ends of the dowels come to a point so that they can slip into the off-center holes. It didn't always work and you broke some posts and had to start over and said some unpleasant things in the back yard. But it was a very nice day. If you can, why not get up and take a walk, you old turd?

Yesterday I finished the steps and added some ornamental touches on the sides. It is pretty much done. Now I just need to let the green wood of the bridge dry out so that it isn't so darn heavy. How many people will it take to move this thing?

Next: Moving on to a new project: the pergola!
