Hello friends
I made a tool to make dowels.
Make a hole with a drill with the same diameter as the required dowel and cut with an iron saw.
Although the surface of the dowel is rough, it is more useful than commercial products because the adhesive works well.
Also, dowels can be made with stable dimensions.
I actually tried it and it was fine.
