Precision Mechanism factory

My first attempt at making a proper schematic for the automatic Precision Mechanism factory I keep always manually rebuilding on every save file.

It features:

• Automatic retry when the build outputs junk.

• Automatic resupply when the build outputs a golden sheet (Same as the retry, but minus the gold ingot).

• Automatically turns itself off after 2 minutes when the related Factory Gauge is satisfied. This circuit can be done more compact with something like Project Red, but I went with vanilla redstone and Create for this schematic. It could probably be optimised better?

V2 Edit: Oops, didn't have those observers pointing at the belts at the right height. Also annoyingly clogs at high volume, so I refactored the inputs and added a vault buffer. The hands need extra stock when too many mechanisms at once eat up all the cogs/nuggets, so I added an "Overstock" to pre-fill before starting, or to un-clog it. Gosh these incomplete mechanisms are persnickety.

P.S. Annoyingly, the Frogports needs to be re-configured since they lose their chains.
