One of the nice features of this house was that it already had a fire pit so I didn't have to construct one as I'd done at our last house. Near the firepit, the prior owners had left a supply of stacked firewood as well as a few logs set on end for seating and one larger log - 16" in diameter and three feet long - set on its side for seating.
As my wife and I were walking around the house a few weeks ago, she expressed that she thought the fire pit - constructed of retaining wall bricks - was ugly. She also shared that she thought the same of the fire pit I'd built at the last house. She was also not a fan of the log seating.
I'm planning to build a new, more attractive fire pit with smokeless features at some point in the relatively near future. But I started on the seating issue first. I got out the 18" electric chainsaw that I'd acquired for removing the stump from the front flower bed, situated the big log on end, and started cutting the log into four sections.
Unfortunately, the chainsaw was not working very well and I stopped and re-started each of the cuts several times. Sharpening the chain didn't seem to do much good. Replacing the chain with an aftermarket Oregon chain (thanks, Project Farm!) did a lot of good, allowing me to finish off each cut in a small fraction of the time I'd spent on each cut initially.
Sadly, my poor chainsaw work left each slab in pretty rough condition. I didnt take pictures of all of them, but here are a couple of them after the chainsaw but before the next step:

I considered a few different methods of smoothing them out, not being particularly worried about achieving absolute flatness. I considered sanding but figured it would take a long time with my random orbital sander and eat through a lot of sandpaper. I picked up a belt sander on special at Harbor Freight but then returned it after I saw a special on a tool that I thought would do the job better without the need for sandpaper - an electric hand planer.
The hand planer took a bit of getting used to, but I got them all pretty smooth and all but one of them pretty flat using the planer. I found and removed a fair amount of rot from the log, which also affected the smoothness.

I mixed up a few batches of sawdust and Titebond 2 wood glue and used it to fill in some of the deeper voids in the wood, especially cracks near the ends of each slab. I didn't wait quite long enough for the glue to set before going over each board lightly with the random orbital sander. I vacuumed off any loose debris and then applied a tape dam around the edge of each slab. I didn't secure the tape dams well enough in some spots.
I mixed up a batch of epoxy and then poured it over the boards. I applied the most epoxy to the least flat board, counting on the epoxy to self level and make it a little closer to flat. I didn't count on the excessive amounts of epoxy building up pressure on the tape dam and spilling out, but that's exactly what happened.

After an hour, I removed the tape dam. The boards were pretty thirsty, so there wasn't much epoxy remaining on the top of the boards to run off and coat the sides. I used my gloved hands to apply the spilled epoxy onto the ends and sides of each slab. Now I'm just waiting for the epoxy to dry and/or cure before I spray on a couple of layers of polyurethane to protect to epoxy from UV or other damage outside. I also need to fashion some legs for each slab. I'm thinking to use either one wider log on both sides of each slab as the legs or two smaller logs on each side. It may just depend on what's already in my firewood pile.
Here's what they looked like about after removing the tape dams:
