The right tool for the right job! This thread is a good startingn point.
Transfer Punch Set - These are used to "transfer" a pattern of holes from one piece to another. Note, when transfering holes from thin materials, the raised part that dimples the material can prevent the circumference of the transfer punch from locating itself relative to a hole.
Examples: Harbor Freight Transfer Punch set
Centering Transfer Center Punch - This is useful if there isn't enough "meat" or thickness around a hole to locate a traditional transfer punch. An example is trying to center a hole through L-track where the bottom of the chamfer is too thin to properly locate a transfer punch.
Examples: Penn Tool Hole Transfer Center Punch
Transfer Screw Set - These are useful to locate holes on the backside of a piece. Say I have 4 1/4-20 threaded holes in a wall and you need to mount a panel to that wall. You insert the transfer screws int to the threaded holes, place the panel against the wall, and dimple the backside by pressing the panel against the transfer screws. Remove and drill the proper locations.
Examples: Transfer Screw Set on Amazon
Center Scribe - Useful to scribe a center line down a long strip of metal (e.g. 1/2 series 80/20 or L-track) to aid in drilling/transfering holes.
Example: Center Scribe
Metal Saw - For cutting 80/20 and other stuff.
Humble Road uses the Makita LC1230 which runs about $540.
I have been looking at Evolution S380CPS which runs about $440.
I think the Evolution has the edge.
Stop Block System - Useful for cutting precise lengths of 80/20.
Example: Kreg system ($140)
Hot Wire Foam Cutter - Will be used to cut the foam used to fill the channels in the van before the top upper layer of XPS.
Example: Hercules Hot Wire Foam Cutter ($140)
Cheap But Accurate DMM (Logging a plus) - Will be used for battery construction and cell balancing.
Example:ut61e
Look into sigrok for logging without installing stupid software. Also considering picking up one of these to check it. Note, the 61e+ is not supported by sigrok. The 61e is supported. There are also good python repositories that support the 61e.
Oscilloscope with CAN Decode - Would be useful. And I've always wanted one. UPDATE: GIFTED!
Example: Siglent 4 Channel with CAN etc ($499)
Top Balancing System - Will be used to top balance cells for battery construction.
Example: ESP32 based system. This system uses a HRPG-300-3.3 which is capable of 60A at 3.8V. This would charge 16 280AH cells in approximately 37 hours from 50% SOC. It would require use of shotty diodes in parallel detailed in that the above thread.
High Capacity DC PSU - Could be used to top balance cells and to test the 12V and 24V electrical system ahead of battery light off. Can also be used as a virtual solar array to provide input to MPPT.
Example:Riden RD6018 ($199)
Capacity Tester - This will be used to test individual cell capacity to allow matching/verifying cells. The example below all so has serial out, so logging of tests via raspberry pi should be pretty easy.
Example: Atorch 4-wire ($100)
Plus-Nut Setting Tool - This Tool is used to set plus nuts consistantly
Example: Astro Pnuematic Tool 1450 is recommended in this forum thread.
Example: Air Powered Option is highly recommended by this youtube video.
THIS WAS A GAME CHANGER!
Air Compressor - Due to the scarcity and price increases of spray adhesives, we are purchasing sprayable adhesive in liquid form and will spray with compressed air. This requires an air compressor.
Example: Central Pneumatic 10 Gal 2.5 HP (178.97) - This compressor has greater than 6CFM at 40 PSI so it will support the HVLP guns we are looking at.
Spray Gun - One for spraying adhesive, and one for urethane.
Example: Central Pneumatic HVLP (16.99) - Not sure if we need the version with the regulator.
Hand Planer - used to match thickness of foam and ribs Example: Ryobi
