I went and dug this slab out of the barn yesterday and made this little bench, put the final coat of finish on it just now (still using a junk camera, sorry)
The legs are simple, the ones under the crotch flair are wider than the ones on the other end. The stretcher is just 1/2 lapped in. I was going to put feet on them but anything I came up with looked out of place to me. It sits very stable, I am going to leave it as is.
