A proposed tech tree starting from a few relatively simple parts. Goal is to get a BLDC motor and driver capable of about 2HP. It needs either a spindle that can directly take high load or a way to drive a spindle that can take high load.
I have a Go project started to try and represent the tech tree as a directed graph. Documenting different "Recipes" means I can find different paths through the graph trading time for money.
Big
- 3D printer
- Circular saw
- Drill
- BLDC motor and driver
- good soldering iron (TS-80, TS-100)
Small
- drill bits
- taps
- large metal square
- multimeter
Consumable
- plywood
- screws
- wood glue
- sand paper
- threaded rod
- nuts
- washers
Node Types
- Lab: These are the essential nodes. A vulcan lab is complete when they are all built.
- Efficiency: Non-essential, but useful.
- Bootstrap: Temporary nodes used to build up to a lab. Can be bypassed.
- Factory: These go beyond the base lab towards specialized production. The goal here is for the community to be able to generate some parts.
Stage 1
- Straight edge for circular saw
- guide for drill
Stage 2
- Convert circular saw to table saw
- convert drill to mock-press
Later
- Modify circular saw to use BLDC
- Modify drill to use BLDC
- ACME die
- Mill press (with thrust bearings)
- Produce Bearings
- Lathe
With an acme die and some heat treating I can take soft iron/steel, cut a threaded rod, then harden it. Keeping it straight will be a challenge. With acme threaded rod it will be possible to build a good mill press.
Spindle Assembly
Used for both lathe and mill, though with CNC we may just end up using the mill as a lathe.
The assembly needs high quality bearings that can take both radial and axial thrust. We can bootstrap and start with low quality bearings, possibly 3D printed then machine our own and replace them.
Dependence
- lathe w/ 3|4 jaw → simple collets
Think about what would be needed for a CNC lath to churn out bearing parts. Stock feed, captive cutoffs and of course CNC.
