I would have stopped as well at the thought of using all those tiny nuts and bolts.
I have had a few projects stall when you get something like that. All you need is time….mull it over…find a way round it, as you have.
Perhaps the worse job I ever stalled on was all those portholes on the Titanic, and tiny square windows. In the end all done in 20 mins with masking tape, a pre-holed template and a fine marker pen…
