I was busy making 3/8" ash dowels for the drawbored mortise and tenon joints for the Roubo bench, when something became clear to me. Woodworking is a very time consuming activity.
At my stage I am slow not only because of my inexperience, but there are naturally more interruptions in the beginning. You need to stop in order to re-hone a tool, but your sharpening station is not properly set up, or you are missing a honing guide or a stone. You need to make a jig for the 1st time (mortising jig, table saw sled, guides to hold your sash clamps etc.). Or you just need to stop to read about a process which you have never attempted before. All these improve with time and practice.
But despite the above, there are a lot of detailed processes that go into woodworking. And each process and sub-process is a skill on its own to acquire. Measuring, laying out, preparing stock, joinery, making dowels, choosing the right glue, honing, tool selection, fettling, safety procedures, dust extraction, wood movement...get my point?
