They started building my boat in 1936.
I have no confidence it will ever be finished.. As you finish one bit another bit is busy deciding to rot rust flake break or fail.
40 years of boats evidences that only you can define when the boat is finished.
The build morphs into maintenance rapidly, as evidenced by the mouldy grey primered projects littering the canals. Boats get away from you. I fix something daily, be it a scratch, a thermocouple failing , or an oil change.
Im sure you will be fine, you appear to have your eyes wide open, enjoy the task.
However you need to apply Kiss principles, because the bits that fail are always the most inaccessible.
