After planing, sanding, and trimming, I ended up with this.
Then, I cut equal size pieces on my cheapo table saw and it was time for a dry fit (alternating the orientation of every other piece).
To try to make the fit a little better, I “jointed” the mating surfaces trying to remove high spots. This involved clamping my plane in a workmate and sliding the piece over the blade.
Second glue up.
Finally, there was block planing and sanding. Then sanding. Mostly sanding.
