Minimum manual crafting

I saw the "less than 111 manual crafting" achievement and I got to wondering what the actual minimum was (and also to plan out my approach for my inevitable attempt at this run).

I figure to get a first assembling machine going, we'd need: 1 steam engine, 1 boiler, 1 offshore pump, 1 electric pole, 1 assembling machine, 1 lab, 10 science pack 1

We start with a stone furnace and a mining drill, which can be used to get all the stone/coal/iron plates/copper plates we'd want (although slowly), by picking it up and moving to a new location. The furnace can also be built into the boiler, since once we have the automated factory we can just make a new one.

• 1 steam engine - 5 gears, 5 pipe = 11 manual craft steps
• 1 boiler - 1 pipe, 1 stone furnace = 2 manual craft steps
• 1 offshore pump - 2 circuit (1 plate, 3 wire), 1 pipe, 1 gear = 8 manual craft steps (3 wire, 4 for final ingredients, 1 final)
• 1 electric pole - 2 wood, 2 wire = 3 manual craft steps
• 1 assembling machine - 3 circuit (1 plate, 3 wire), 5 gear, 9 plate = 14 manual craft steps (5 wire+8 ingredients+1 final)
• 1 lab - 4 conveyor belts (1 plate 1 gear for 2 conveyors), 10 gear, 10 circuits (1 plate, 3 wire) = 40 manual craft steps (15 wire, 2 for gears for belts, 22 final ingredients, 1 final)
• 10 science - 1 plate 1 gear = 20 manual craft steps (10 gear, 10 science)

For a total of: 11+2+8+3+14+40+20 = 98 manual craft steps. Am I missing 13 steps somewhere that would take it to 111, or is there a little leeway?

• Edits from comments: I missed assembly machine 2 and refinery, so 100 strictly required (102 if you want a pick before assembly machine 1).

• Double edit: Apparently a pick is actually two crafts, not one (you have to build a stick!). Also, since both mining drills and Assembling Machine 1 aren't actually buildable until Assembling Machine 2 is unlocked, there's actually 120 red science before things can really get going (110 of which will have to be made in the Assembling Machine 1). So... get lots of use out of that starter mining drill.
