Well, got those other tenons chopped, both sides glued up. 

Handles sticking up are chisels I was using.   I stick them into a dog hole, saves them from rolling off onto the floor...or my foot. 

Bandsaw work this evening..

Top/crest rail, roughed out.  Planes, and other tools to smooth it out..

Allowed for a 1" tenon on each end.   Now, what did I use to draw them curves with...

Well, I had these three seat brackets.  Chose one of the better ones to lay out the curves.  These three are for the front, middle, and back seat bracket.   I'll resaw a bunch of slats later, and attach the slat to these brackets.   Forms a curve for the bottom to sit in. ...MY bottom, that is.   Again, allowed for 1" long tenons, I can adjust for length after a few mortises are chopped.    The middle bracket will be a bit different, as there is nothing the tenon into,  Might cut a dovetail of some sort.

Don't have a fancy compass plane, so maybe a scrub plane will work on the inside curves?  Harbor Freight #33 made into a scrub plane.   Went at about 45 degrees to the grain, to erase the saw marks.. then a sander to finish things up.   Had a blank for the back's bottom rail, needed to be S4S instead or rough sawn..

Stanley No. 5, type 17/parts plane.   Work all four sides until clean and smooth, and squared.   Made a big pile of shavings, too..

As for the two side units?

Oh, they are just hanging around......a bit of adjustment needed, then time to start chopping square holes, again...stay tuned

I think I can hear the crickets and feel the warm summer breeze as you set on the porch watching a beautiful summer sunset!

 

Lookin' Good!
