making sequence :
I cut some boards for the rest parts.
The longest and narrow one was for the stretcher.
After dimensioning, I had to make dadoes first.
If I did make a curvature first, I could not get any reference face for dado.
After I sawed down to pencil line,
I plowed out with router plane.
Finally, I made a curvature with my own made frame saw.
With a little of shaving, I got the completed stretcher ….
See you again :)
