Why it took four weeks to get a porch swing

I have high hopes for building a porch swing from scratch one of these days, but the initial idea was to use wood from a black walnut in the backyard which a friend and I have yet to examine and see if it can be milled. Meanwhile, my neighbors tossed a broken porch swing a few months ago and I figured a rebuilt swing was better than no swing, at least until I carve my own swing straight from the raw timber of my land.

The swing is a bit old but in overall good shape save for the four cracked boards that connect the back of the seat to the bench:
No problem, thought I - I have enough 1x4 (which is wider than the existing boards, but that's not an issue) and I can even use my new dado blade set to easily carve the groove. Of course it wouldn't be so simple. The arbor nut on the table saw didn't want to budge, so I was forced to improvise using just the normal blade. I ran each board through multiple times, shifting the cut width to cut the outer edges of the groove and remove some of the wood in the middle, then used a chisel to clean everything out. The only tricky thing, really, is to remember that the blade will cut further on the underside of the board than on the top - I marked a second line further down the board to compensate and tell me when to stop.

Since this isn't the 'final' porch swing for the house, I took the opportunity to test out some all-natural stain samples to see how they look, and how they weather:

Now to paint the porch.
