Hi, I usually live in the gardening forums and am new to woodworking - thanks!

We want to build a gazebo using ash logs. We have acres of tall straight ash trees that we can cut in matching sizes. (and I fear they are eventually doomed anyway because of emerald ash borer)

My husband is experienced at both logging and woodworking. He has used raw lumber and planed it for projects, but this time we would like the look of "logs" rather than lumber. here are some sample photos of the log look we would like, although not exactly either design.

How do you remove the bark?

How and how long do you dry the logs?

What do you use to seal it?

How often does it need to be resealed?

Other considerations?

I have done a web search and come up with very little, so I was hoping someone here might have some experience.

Thanks in advance for any suggestions!
