It's definitely 5/4. I measured it. I went with the thick stock because
I'm copying a piece that I saw in a furniture store. You're right, I'm
sure it's overkill from a structural standpoint but I like the way it
looks.

So what exactly would I need to cut these by hand? From what I have
gathered, I need a dovetail saw, some sort of guide and a nice set of
chisels. I have none of the above. Recommendations?

Thanks for the help,
